Subclavian steal syndrome (SSS) is a clinical entity characterized by brachial and basilar insufficiency as a result of critical proximal subclavian artery stenosis or occlusion. We report a patient of giant hypervascular thyroid nodule presenting with features of SSS. The left hand ischemia and symptoms of vertebro-basilar artery in our patient were probably related to stealing of blood by the...

Basilar aneurysms that are not amenable to standard endovascular treatment via the femoral approach because catheterization is difficult pose a rare but serious problem. We present two cases of basilar tip aneurysms successfully treated by the endovascular route after direct puncture of the right vertebral artery. In both patients, the left vertebral artery was tortuous, small, and irregular, a...

A case of Moyamoya disease associated with basilar aneurysm was reported. This case was rare in that it developed from subarachnoid hemorrhage attributable to rupture of basilar aneurysm. The pathological findings of the intracranial blood vessels were almost identical to the findings presented in previous reports. In the vertebral basilar artery system, a remarkable intimal thickening of the i...

Coiling of a wide-necked basilar tip aneurysm can be accomplished in selected cases by placing a single Neuroform stent horizontally across the aneurysm neck via a posterior communicating artery approach rather than by placing 2 stents in a Y configuration via a basilar artery approach.

Kissing aneurysms associated with a proximal basilar artery fenestration are an exceedingly rare and unique therapeutic challenge due to anatomical complexity. This report describes double-barrel stent-assisted technique with dual closed-cell stents for the successful endovascular coiling of kissing aneurysms from a proximal basilar artery fenestration.

BACKGROUND AND PURPOSE The effects of hemodialysis on the cerebral circulation of humans and the correlation between changes in blood flow velocity in the basal cerebral arteries and those of several physiological variables influenced by hemodialysis have been inadequately studied. METHODS Blood flow velocities were obtained from the middle cerebral artery and the basilar artery by transcrani...

A 47-year-old male presented with a 2-year history of hemifacial spasm. Magnetic resonance imaging performed showed his tortuous basilar artery with nerve compression, and the patient was treated conservatively with botulinum toxin injections with complete resolution of symptoms. This rare disease was caused by his long history of hypertension, which led to his major basilar artery dolichoectasia.

We report a 61 years old male presenting with a right cerebral infarction, along with a type I persistent left proatlantal artery (PA), which is a form of primitive carotid-basilar anastomosis. The patient had an absence of the ipsilateral vertebral artery (VA) and hypoplasia of the contralateral VA, while the basilar artery was supplied by the PA. Other vascular anomalies present were a fusifo...

Distribution of atherosclerotic vascular lesions in the intracranial posterior circulation has not been as well documented as in the anterior circulation. Data regarding this aspect among Asian stroke patients are scarce. In present study, we sought to investigate the distribution of posterior circulation vascular lesions in Chinese stroke patients. We examined consecutive patients with acute i...

We studied isolated basilar artery segments from a rabbit model of chronic cerebrovasospasm. Autologous blood placed around the basilar artery of rabbits killed 1, 2, 3, 4, 5, 6, 7, or 9 days later caused narrowing of the segments with a biphasic time course. The first (immediate) phase was reversed by intra-arterial papaverine; the second phase exhibited an increasing component of narrowing th...
