Twenty patients with basilar artery occlusion and three patients with bilateral vertebral artery occlusions have been studied. The clinical data at the time of the ictus and the long-term follow-up data have been correlated with the site and extent of the basilar artery occlusion and the type of collateral flow. Patients with hypertension and with coma at the outset have a grave prognosis. The ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015209317 DESCRIPTION A 48-year-old man presented with a 24 h history of neck pain, vomiting, vertigo and impaired gait. On examination, he was found to have left gaze provoked nystagmus and left arm and leg dysmetria with mild weakness, symptoms attributable to cerebellar dysfunction. He underw...

We report here on a rare case of a ruptured basilar tip aneurysm that was successfully treated with coil embolization in the bilateral cervical internal carotid artery (ICA) occlusions with abnormal vascular networks from the posterior circulation. A 43-year old man with a familial history of moyamoya disease presented with subarachnoid hemorrhage. Digital subtraction angiography demonstrated c...

The superior cerebellar artery is the most consistent branch of the basilar artery and arises near the bifurcation of the basilar artery. A bilateral origin of the superior cerebellar arteries from the posterior cerebral arteries has been rarely reported in the literature. Reporting variations in brain vessels is important for neurosurgeons to safely and confidently treat pathologies in this re...

The posterior circulation of the brain constitutes the vertebrobasilar system and its branches, which are responsible for about 30% of the brain's blood supply. The aim of this study was to describe the anomalies of the basilar artery, especially fenestrations. For that purpose, we examined 50 patients with computed tomography (CT) angiography during an 8-month period. In the CT reports of 2 (4...

Transmural nerve stimulation (TNS) induced relaxations in porcine and bovine basilar arteries which were abolished by tetrodotoxin (TTX) and by L-nitro-arginine (LNAG). However, TNS induced contractions in equine basilar artery which were abolished by TTX and by guanethidine, but not by LNAG. These results suggest that the TNS-induced contractions of equine basilar arteries may be mediated by n...

Acute thromboembolic occlusion of the basilar artery accounts for 6% to 10% of large-vessel stroke in humans. Because of the brain region supplied by this artery, the case fatality rate is the highest for all ischemic stroke subtypes, ranging from 40% to 86%. Patients who undergo successful recanalization of the basilar artery by intra-arterial thrombolysis have lower mortality of 39%. Consider...

A 71-year-old man with acute basilar artery occlusion was referred for endovascular treatment 6 hours after the onset of stroke with a Glasgow Coma Score of 3 and National Institutes of Health Stroke Scale of 27. A cerebral arteriogram revealed occlusion of the left vertebral artery proximally and thromboembolic occlusion of the basilar tip. Direct aspiration and mechanical thrombectomy with va...

Duplication or fenestration of the basilar artery, a result of an embryologic malformation, has an incidence of up to 5.3% in the general population. The most common complication of this anomaly is the formation of aneurysms. Thrombosis of a partially duplicated basilar artery developed in a 43-year-old man who complained of visual disturbances followed by seizures and coma, and who eventually ...
