We describe the use of abciximab to prevent rethrombosis of the basilar artery after transluminal angioplasty. A 60-year-old patient with vertebral basilar insufficiency and acute occlusion of the basilar artery underwent revascularization with urokinase and angioplasty. Despite the repeated use of urokinase and angioplasty under anticoagulation with heparin, the basilar artery immediately reth...

BACKGROUND AND PURPOSE Dolichoectasia of the basilar artery is a characteristic finding of Fabry disease. However, its prevalence, severity, and course have been poorly studied. This study quantitatively evaluated, by MRA, a panel of basilar artery parameters in a large cohort of patients with Fabry disease. MATERIALS AND METHODS Basilar artery mean diameter, curved length, "origin-to-end" li...

Basilar artery territory stroke may result from embolism arising from the site of vertebral artery occlusion. This stroke mechanism (local embolism) has been well documented in the middle cerebral artery territory from extracranial internal carotid artery disease but not fully appreciated in the vertebral basilar circulation. We report two patients whose clinical presentation indicated major ba...

The incidence of basilar artery fenestration is approximately 0.6% in angiographic studies and more in autopsy studies [1]. The most common site of basilar artery fenestration is proximal part [2]. Basilar artery fenestration aneurysms are very rare, posing unique challenges. Reported incidence of aneurysm at basilar artery fenestration site is 7% [3]. Surgical treatment of such aneurysm is usu...

Variations in the cerebrovascular tree can increase surgical or interventional morbidity. To date, only scant comments are to be found in the literature regarding intraluminal variations of the basilar artery. To further elucidate such anatomy, a cadaveric study was performed. One hundred and fifty human brains were evaluated for the present study. The basilar artery was identified in each and ...

BACKGROUND AND PURPOSE Acute basilar artery occlusion portends high risk of stroke and death. Thrombolysis or endovascular therapy has been limited to patients who present within hours of symptom onset. Without recanalization, acute basilar artery occlusion almost always results in death or severe disability. SUMMARY OF CASE We report a case of basilar artery occlusion and successful endovasc...

BACKGROUND AND PURPOSE Aggregation and adherence of platelets to vascular endothelium are increased during diabetes mellitus, and thus responses of cerebral arteries to products released by platelets may have important implications for the pathogenesis of stroke during diabetes. The goal of this study was to determine whether responses of the basilar artery to products released by platelets are...

We tested the hypothesis that dilator responses of the basilar artery to endothelium-dependent vasodilators are mediated by activation of tyrosine kinase in vivo. Using a cranial window in anesthetized rats, we examined responses of the basilar artery to acetylcholine and bradykinin. Topical application of acetylcholine and bradykinin increased diameter of the basilar artery in a concentration-...

AIM We aimed to examine the basilar artery in an experimental subarachnoid hemorrhage (SAH) model both from the ultrastructural and radiological aspects and tried to evaluate the benefit of proanthocyanidin (PC), an antioxidant matter, in reducing vasospasm. MATERIAL AND METHODS A total of 21 male New Zealand rabbits were divided into three groups after performing angiography. Group I: Contro...

Our goal was to examine whether exercise training alleviates impaired nitric oxide synthase (NOS)-dependent dilatation of the basilar artery in Type 1 diabetic rats. To test this hypothesis, we measured in vivo diameter of the basilar artery in sedentary and exercised nondiabetic and diabetic rats in response to NOS-dependent (acetylcholine) and -independent (nitroglycerin) agonists. To determi...
