After reporting our initial results, the results of VA stenosis operations and the follow-up studies are analyzed. Median pre-interventional stenosis degree was 75% (IQR 70-85) with a median lesion length of 4.5mm (IQR 4-7.5). 3]. Type of stent and cerebral embolic protection device may influence the rate of postprocedural neurologic ischemic events. Primary end points were analyzed as early results (≤30 days after the procedure), and secondary end points were long-term results (>30 days). Successful EVT of the VA stenosis was achieved in 68 patients (93.2%). The authors report experience of intravascular angioplasty of atheromatous ostial strictures of the vertebral artery in 24 patients. Materials and methods: We performed a prospective observational study using a single stroke center registry to investigate the risk of recurrent stroke and vascular outcomes in patients with . Following anastomosis the cerebral blood pathway is physiological. In the NDES Group, 9 patients had pre-stent angioplasty; 2 had post-stent angioplasty. However, differences were not statistically significant. A histopathological analysis of segments of the thrombosed large intracranial arteries was carried out on eight patients who died within 28 days after brain infarction. Found insideVERTEBRAL ARTERY INTERVENTION Approximately 25% of ischemic strokes involve the posterior or vertebrobasilar circulation. Stenosis of the vertebral artery ... PMC However, one patient (2%) died of nonneurological causes, and one (2%) suffered a stroke that occurred within the 30-day postprocedural period and was related to a complicated coronary intervention. Objective: To report a single-center experience using drug-eluting balloon mounted stents (DES) for endovascular treatment of atherosclerotic ostial vertebral artery stenosis (OVAS). The book also gives an insight into the clinical manifestations of carotid and vertebral artery dissection and to the possibilities and limitations of the main diagnostic tools, ultrasound, CT and MR imaging, and angiography. 23/30 had contralateral VA involvement. Because vertebral artery stenosis can reduce or even block blood flow to your brain, it significantly increases your risk of developing a stroke or transient ischemic attack (TIA). Although the rate of restenosis was half that seen with the use of bare metallic stents, 21% of patients still developed moderate or severe ISR. Between the patients with subclavian arterial stenosis and those without this artery stenosis, there was no statistical significant difference observed in ABI level. Endarterectomy for atherosclerotic stenosis at the origin and proximal extracranial vertebral artery has been performed via a supraclavicular incision since the early 1960s, with variable success rates. ic roadmap'' was made of the subclavian and the vertebral FIG 2. Comorbidities included hyperlipidemia (83%), hypertension (70%) and prior stroke (63.3%). Refining the concept of paradoxical LFLG AS It is frequently assumed that normal LVEF implies normal LV systolic function and normal transvalvular flow and, consequently, high transvalvular gradient in the presence of severe AS. This association could have a significant genetic component. During this period, 7993 eversion endarterectomies were done for significant carotid artery stenosis. In total, 89 patients were recruited (67% male, mean age: 72 years). 2007 Feb;106(2):222-5. doi: 10.3171/jns.2007.106.2.222. Univariate analysis failed to identify any variable predictive of long-term patency of successfully treated VA stenosis. Carotid duplex ultrasound has some difficulties in this question. When all cause morbidity/mortality within 30 days from stent-PTA and stroke or death from stroke in the treated vascular territory during the first 12 months of follow-up are combined, the incidence of periprocedural complications and disease progression for the first year is 10.3% in VAOS patients and 17.6% in the VBIS group. Anticoagulants have been used to alleviate symptoms in some cases but are ineffective in solving the primary hemodynamic problem. One had a supratentorial completed stroke, and the other two hat TIA or RIND, but without any notable lesion in the angiograms.

Diagnosis and classification of vertebral artery stenosis are more demanding than in The techniques most often used to reconstruct the distal vertebral artery at this level include (1) saphenous vein bypass from the common carotid, subclavian, or proximal vertebral artery; (2) transposition of the external carotid or hypertrophied occipital artery to the distal vertebral; and (3 . The authors have reviewed their experience in the management of 55 patients admitted to Henry Ford Hospital with symptoms of vertebrobasilar insufficiency and associated proximal vertebral artery stenosis or occlusion. Further prospective comparison with medical preventive strategies is warranted. The vertebral arteries are commonly asymmetric in diameter, and it is not uncommon for one vertebral artery to be atretic, a finding that is slightly more common on the left than the right . A transient ischemic attack (TIA), or "mini-stroke" causes a temporary loss of brain function, but a full-blown stroke is the next step. B,Post stenting angiogram (NIR Primo stent) of the left subclavian artery shows excellent antegrade filling of the left ver-tebral artery. There were no cases of cerebral infarction of the posterior fossa. This procedure is ideal for people who have moderate to severe stenosis. Conclusions: These blockages can greatly increase your risk of stroke. They underwent extracranial-intracranial bypass surgery to relieve their symptoms. The remaining seven patients had single events, four of which caused permanent deficit. Simplified endovascular access to the VA origin after angioplasty is demonstrated. Overall, this test takes about an hour and requires you to lie flat afterward for two to four hours. NECK VESSELS (MRA & CTA): • Basilar Artery: 50% stenosis (distal) and reduced flow. We analyzed the long-term outcome of consecutive patients with OVAS who received either medical treatment (MT) or vertebral artery stenting (VAS). Method/Design: This trial is a 1:1 randomized, controlled, multicenter, non-inferiority trial that compares the DCB to BMS in terms of angiographically assessed target lesion binary restenosis (≥50%) at 12 months in endovascular treatment of symptomatic patients with VAOS. An angiographic core laboratory-adjudicated target lesion binary restenosis (≥50%) at 12 months of follow-up was selected as primary efficacy endpoint to assess the DCB treatment effect. From February 2001 to March 2013, 73 consecutive patients (33 men with a mean age of 61.7 ± 8.8 years) underwent EVT for symptomatic high-grade VA stenosis. Background. Subsequently, postprocedural magnetic resonance imaging (MRI) including diffusion weighted imaging and apparent diffusion coefficient were obtained within the first 24 hours after completion of the procedure. This difference was statistically significant (p less than 0.01). Clinical features, location of infarct, and outcome differed between groups and reflected the presumed mechanisms of stroke. Our team is the region's leading resource for brain health emergencies, including stroke. No major complications such as dissection, vessel perforation, hemorrhage or ischemic events occurred. Two patients underwent bilateral procedures. When an artery inside the skull becomes blocked by plaque or disease, it is called cerebral artery stenosis. From 1977 to 1989, 28 patients, 18 men and 10 women, underwent 29 proxi mal vertebral artery reconstructions. Nineteen patients (19.8%) experienced non-localizing symptoms possibly compatible with VB TIA, none of whom had a stroke. MATERIAL AND METHODS Eighteen elderly patients with symptomatic vertebrobasilar artery stenosis who underwent endovascular stent-assisted angioplasty (ESAA) in our department were studied. Complications included one stent migration, one small ischemic infarct in the posterior circulation, and a femoral artery thrombosis. All patients were examined by neurologists 1, 3, 6, 9, and 12 months after entry and then every 4 months. It causes as many as 20% of posterior circulation stroke. Comprehensive indications for treatment of symptomatic vertebral stenosis remain unavailable. CAS was performed with distal embolic protection device on patients with both standard and high risk of endarterectomy. Patient 6. Then, it winds behind the superior articular process of the atlas. The higher age, symptomatic lesions, negative history of hypertension, and hs-CRP difference had significant association with the presence of new DWI lesions in univariate analysis (all P<0.05). Methods: The histological characteristics of the thrombosed arteries were plaque rupture in three, intramural haemorrhage in one, ulceration in one, and thrombosis in the absence of plaque rupture or intramural haemorrhage in three. Next, a small flexible balloon is inflated, pushing plaque back against the artery walls and opening the blockage. Atherosclerosis of the intracranial cerebral vessels was more severe than that of the extracranial vessels. We therefore describe the clinical and pathological features of recent, symptomatic internal carotid artery occlusion to examine the pathogenetic role of plaque instability at both extracranial and intracranial sites. Found inside – Page iThis must-have manual for surgical residents and vascular surgery trainees is copiously illustrated with more than 250 original line drawings. Right subclavian artery is fed by a retrograde flow through the right vertebral artery (subclavian steal). Emergency Diagnosis and Response Postoperative neurological deficits due to intraoperative brain ischemia did not occur, and MR imaging demonstrated no new postoperative ischemic lesions in any of the patients. The mechanisms of thrombus formation in atherosclerotic cerebral arteries are still controversial, although intraplaque haemorrhage and rupture of the atheromatous plaques have been proposed. He had a stroke after the procedure which has left him paralized on his left side. Although the presentation of patients with vertebrobasilar insufficiency is generally characteristic, we believe that a specific diagnosis can be established only by angiographic means. The imaging follow-up was performed with Doppler ultrasound (DUS) as a primary screening modality. There was no significant difference between the two groups in the rate of RS during 12 months after surgery. Since postmortem examination fails to provide information about hemodynamics, attention has been focused on cases studied arteriographically during life, with particular regard to the pathway by which the intracranial vertebral-basilar system is supplied. At 12-month follow-up, no patient reported recurrent vertebrobasilar ischemic symptoms or had VA restenosis. Percutaneous trans-luminal angioplasty (PTA) might offer a promising treatment modality, but re-stenosis rate is high. DWI within 3 days postoperative showed asymptomatic embolization 2 (4.1%) patients in the DCB group and 9 (19.6%) patients in the BMS group (p=0.004). For vascular reconstruction in cases of atherosclerotic stenosis at the origin of the vertebral artery, we use vertebral to subclavian artery transposition. Hypertension and diabetes mellitus were identified as factors associated only with intracranial atherosclerosis (p < 0.001), whereas ischemic heart disease was associated with atherosclerosis in both the intracranial (p < 0.001) and extracranial (p = 0.012) vessels. Literature suggests that the most significant factors associated with ISR in patient with OVAS include cardiovascular comorbidities such as hypertension and diabetes and the length of the lesion (2. Angioplasty and stenting appears to be technically feasible and safe in asymptomatic and symptomatic vertebral stenosis. This is an underdiagnosed condition, and the incidence of significant vertebral artery (VA) stenosis has been underappreciated. Angioplasty was associated with higher frequency of elevated post-procedural hs-CRP in comparison to angiography (P=0.003). The early complication rate was 5.5%, which included one periprocedural transient ischemic attack, two hematomas at the puncture site, and one allergic reaction to the contrast agent. Speed of treatment is critical for recovery, and our policies and processes for stroke care have been recognized by The Joint Commission. There were transient, minor complications in 2 patients. There were no procedure-related mortalities. The degree of stenosis ranged from 46% to 83% (mean, 67.3% +/- 11.9). The significance of such instability in arteries supplying the brain is less well appreciated. The new artery bypasses the damaged blood vessel and restores healthy blood flow in the brain. Follow-up revealed no deaths, however, three cases exhibited symptoms of cerebral ischaemia. Two (7.6%) patients had in-stent restenosis and underwent retreatment with angioplasty. Background Prevention of cerebrovascular ischemic lesions due to atherosclerotic occlusive disease (AOD) of supraaortic vessels plays a major role in the daily work-load of a vascular surgeon. Duke University Hospital is proud of our team and the exceptional care they provide. The pathologic process was atherosclerotic stenosis in 283, kinks in 25 and extrinsic compression in 17 cases. With a low surgical risk . If you require surgery, our highly skilled neurosurgeons -- who have undergone advanced training in this type of complex brain surgery -- will choose and perform the procedure that's best for you. Two patients (1.9%) died postoperatively and five patients (4.7%) had nonfatal neurologic complications. The first lesion is concentric and high-graded, while the second lesion is intramural hypoechogenic hematoma . Magnetic resonance imaging showed contact between the left REZ and vertebral artery (VA), which had shifted to the left. Results: Thirty patients were treated and were predominantly male (n=25). Hospital mortality was 0.6%. Bilateral extracranial vertebral compromise results from occlusion or stenosis of both vertebral arteries, or of one vertebral artery when the other is vestigial. The vertebral artery is a major artery in the neck. Smoking was associated with narrowing of the extracranial vessels only (p = 0.0054). Surgical reconstruction of the affected area deserves further evaluation in the management of these patients. Percutaneous transluminal angioplasty (PTA) with stent should be restricted to patients with hos-tile neck, contralateral laryngeal nerve palsy, high-grade restenosis, or very distal ICA stenosis. Endovascular treatment of vertebral artery (VA) origin stenosis typically requires placement of the proximal end of the stent within the lumen of the subclavian artery or aorta to provide complete coverage of the ostial lesion. To compare the angiographic and clinical outcomes of drug-coated balloon (DCB) with distal embolic protection devices (EPD) vs bare metal stent (BMS) without EPD in the treatment of symptomatic vertebral artery origin stenosis (VAOS). 2011 Jul-Aug;20(4):369-76 Caplan L, Wityk R, Pazdera L, Chang HM, Pessin M, Dewitt L. These can be performed with or without contrast dye. All patients had severe bilateral distal vertebral artery or basilar artery disease. Arterial occlusion was most commonly observed in vertebral artery, with incidence of 27.9%. Results Stenoses of the intracranial vertebral artery (24 patients) and basilar artery (6 patients) were treated with stents (10 patients), angioplasty alone (13 patients) or both (5 patients). Finally, we discuss the gaps in the current understanding of VAOS and how best to explore them in the future. When MRI or CT scans are used to examine blood vessels (angiograms), they are called MRAs and CTAs. VAOS was performed for patients with greater than 70% stenosis of vertebral artery origin and contralateral occlusion, stenosis or atresia, and posterior circulation stroke or TIA, need for coronary artery bypass graft, bilateral anterior circulation disease, and ipsilateral posterior inferior cerebellar artery TIA/stroke with no other embolic source, ... Subclavian artery stenosis was usually treated by surgical bypass surgery.In recent years, with the progress of interventional therapy equipment and technology, more and more patients have obtained satisfactory curative effect through interventional therapy.Interventional therapy mainly includes simple balloon dilatation and stent placement. J Endovasc Ther. Six patients presented as stroke, ten as TIA and twenty-three were treated on an elective basis due to contralateral occlusion. Two patients had symptoms of anterior circulation ischemia with carotid artery occlusions and reduced supply to the anterior circulation from the stenosed vertebral arteries. indexed AVA ≤0.6 cm2/m2, a mean pressure gradient (MPG) <40 mm Hg, an LVEF ≥50% and a stroke volume index (SVi) <35 mL/m2. Background and Aims:Bilateral intracranial vertebral artery disease (ICVAD) often has poor outcomes. Unlike the endovascular treatment of carotid artery stenosis, which has been the subject of multiple investigations and trials, the epidemiology, risks, and treatment strategies of extracranial vertebral artery disease are much less understood. A test of interinstitutional comparability of x-ray interpretation revealed greatest agreement when lesions compromised more than 50% of the arterial lumen. The exact prevalence of extracranial vertebral artery (VA) stenosis is undetermined, with estimates ranging from 7% to 40%. Restoring or enhancing blood flow in the narrowed arteries, reduces the risk of a potentially life-threatening stroke. Broussalis E, Kunz AB, Luthringshausen G, Klein S, McCoy MR, Trinka E, Killer-Oberpfalzer M. Interv Neuroradiol. 2003). The Montreal Cognitive Assessment Scale (MoCA), Hamilton Depression Self-assessment Scale (HAMD), and Hamilton Anxiety Self-assessment Scale (HAMA) were also used to evaluate the cognition, depression, and anxiety of patients at different time points of the study, and analyzed the correlation between the changes of cellular metabolism in the hippocampus and the scores of MoCA, HAMD, and HAMA. Approximately 25% of ischemic strokes involve the vertebrobasilar circulation (, 1,, 2).Vertebral artery (VA) stenosis may account for up to 20% of vertebrobasilar ischemic strokes (, 3-, 7).In an angiographic study of 4748 patients with ischemic stroke, some degree of proximal extracranial VA stenosis was seen in 18% of vessels on the right side of the brain and 22% of vessels . There were eight late deaths from 1 to 9 years, with a 12-year actuarial survival rate of 75.8%. Mean duplex follow-up was 78.6 months (range 3-146). Carotid endarterectomy was still found to be beneficial when all strokes and deaths were included in the analysis (P<0.001). Percutaneous transluminal angioplasty of the subclavian artery was performed in 35 patients. Mean ostial stenosis at presentation was 80 ± 14.8%. The VA lesions in seven patients were complete occlusions, and three patients had severe atherostenosis. Endovascular treatment of vertebral artery stenosis (VAS) is a safe and effective technique for treating symptoms caused by posterior circulation ischemia with high technical and clinical success rates, low complication rates and durable long-term results. Vertebral to subclavian transposition, Vertebral Artery Reconstruction: Results in 106 Patients, Superficial temporal and occipital artery bypass pedicles to superior, anterior inferior, and posterior inferior cerebellar arteries for vertebrobasilar insuffiency, Results of vertebral artery reconstruction, Subclavian artery angioplasty and the origin of the vertebral artery, Percutaneous transluminal angioplasty (dilatation) of carotid, vertebral, and innominate artery stenoses, Transcutaneous angioplasty of vertebral artery atheromatous ostial stricture, Vertebral arteriovenous fistula following anterior cervical spine injury. Twenty-seven patients had crescendo TIA's or stroke in evolution and were considered to be clinically unstable. Nine men and one woman (average age, 65.9 years +/- 11.6 [standard deviation]) were included. Symptoms resolved in 30/31 (96.8%) patients treated with NDES and 11/12 (91.7%) treated with DES. One patient (3.3%) died after the procedure, two had stroke (6.6%) and one a subarachnoid haemorrhage without ensuing deficit. None of the remaining 34 patients experienced further ischemic events, and the mRS score in all of these patients remained unchanged during a mean follow-up period of 54 months. Follow-up angiography (range, 4-48 months; mean, 14.7 months) showed insignificant stenosis in 9 patients, mild in 6, moderate in 4, and severe in 1. Follow-up with duplex scan was available in 26 patients and was complete in 24. Dependent upon the stenosis degree of vertebral artery, subclavian artery and renal artery measured by DSA, the patients were divided into normal group (stenosis < or = 50%) or pathological group(stenosis > 50% or blocked lesions). Proximal vertebral artery reconstruction yields good clinical long-term results, and duplex scan is a useful tool in the follow-up of these patients. In the long-term follow-up, there were no transient ischemic attacks or strokes, non-neurologic mortality was 3.13%, and the recurrent restenosis rate was 4.4%. Editor's Choice - Management of atherosclerotic carotid and vertebral artery disease: 2017 clinical practice guidelines of the European Society for Vascular Surgery (ESVS). 22 A meta-analysis performed by Borhani Haghighi et al. One instance of technical failure was caused by failure of the guidewire passage. There were significant association between post-procedural hs-CRP level (P=0.02) and hs-CRP difference (P=0.003), and the number of new lesions; and the hs-CRP difference and the accumulated lesion surface area (P=0.009). ABI < 0.9 indicated higher risk of stenosis or occlusion of vertebral and renal arteries (P = 0.008 and 0.047 respectively). There were four (9.5%) transient complications (< 30 minutes): two cases of vessel spasm and two of cerebral ischemia. Four of these seven complications occurred after combined vertebral and carotid surgery. Dilatation of stenosis at the origin of the vertebral artery, using a Grüntzig balloon catheter, was attempted in 5 selected patients and was successful in 4. The patients with stenosis or occlusion of arteries had lower ABI (P = 0.000), and the patients with stenosis or occlusion of vertebral and renal arteries also had lower ABI (P = 0.003 and 0.02, respectively), compared with those without stenosis. One patient died of acute myocardial infarction 2 months after surgery and another developed a left thalamic hemorrhage (mRS score of 5) at 42 months postsurgery. The stenosis degrees of 51%-74% and 75%-99% were most commonly observed in renal artery, with incidence of 22.1% and 5.8%, respectively. Their frequency is suggested by the observation that during a 20-year period, 1,382 carotid, 789 supra-aortic trunk and 683 vertebral operations were performed. Atherosclerosis is the buildup of cholestero l , fat and other substances traveling through the bloodstream, such as inflammatory cells, cellular waste products, proteins and calcium. To evaluate our early experience using self-expanding stents to treat atherosclerotic vertebral artery ostial stenosis (VAOS), with respect to technical feasibility and clinical and imaging follow-up results. J Stroke Cerebrovasc Dis. A search strategy using the terms 'stents', 'drug-eluting stents', 'atherosclerosis', 'vertebral artery', and 'vertebrobasilar insufficiency' was employed through Medline. Of the 407 patients in the registry, 80 (20%) had V1 segment lesions. However, there are limited data on whether they have any advantage over BMS in vertebral artery stenosis (VAS). Results: (a) Preintervention angiography of aortic arch shows occlusion of the inominate artery and left common carotid artery, as well as high-grade stenosis in the prevertebral segment of the left subclavian artery. All patients had transient ischemic attacks (TIA's) suggestive of vertebrobasilar ischemia. This diagnostic uncertainty is tried to be solved by improving the criteria system of stenosis grading in internal carotid artery.The aim of this article is to give an overview about the importance and role of extracranial duplex ultrasonography in stroke prevention based on the latest guidelines. Purpose: To evaluate the feasibility and preliminary results of using paclitaxel-eluting stents for angioplasty and to treat symptomatic atherosclerotic ostial vertebral artery (VA) stenosis. In this select group of patients with severe disease, direct vertebral artery operations have resulted in significant long-term relief of symptoms and prevention of transient ischemic attacks and strokes. Initial intraoperative angiography confirmed severe stenosis at the initial segment of the left vertebral artery and proximal subclavian artery a. In this series, 69% had complete resolution of symptoms; the mortality rate was 8.4% and the morbidity rate 13.3%. Patients were treated either with a SeQuent Please NEO or Neuro Elutax SV DEB. Three patients with severe atherosclerotic vascular disease underwent vertebral artery stent placement using a balloon expandable stent. While medical management remains the mainstay for stroke prevention, surgical and/or endovascular intervention is indicated in selected patients. The mean age of the cadavers at death was 77.2 years (range, 68-88 years). Data collected included demographics, comorbidities, presenting symptoms, stenosis severity, contralateral VA stenosis and/or carotid stenosis, type of stent used, angioplasty before or after stenting, post-treatment residual stenosis, clinical and radiological follow up and retreatment. The authors summarize their experience with stent deployment in the treatment of vertebrobasilar artery (VBA) insufficiency. Thirty-four patients had associated stenotic or occlusive lesions of the internal carotid artery. Intracranial stenosis is the narrowing of an artery inside the brain due to buildup of plaque inside the artery. However, no statistically significant intergroup differences were observed. We present convincing and reproducible data to aid neurosurgeons in choosing the procedure best suited to their patients. A neurosurgeon makes a small incision, inserts a catheter, and guides it through your circulatory system to the blocked artery. In these instances, endovascular treatment provides a popular and safe alternative to open surgical techniques. Twenty-one patients had contralateral VA involvement. Three patients had a major brainstem stroke. Clinical practice is allied with basic science to guide all those with an interest in stroke on the diagnosis and management of intracranial atherosclerosis. Know the facts: read this book! All procedures were performed without use of cerebral protection. The observed stroke rate was 8.5 times the expected infarction rate for a normal population.
