چکیده

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 presence of surface collateral flow may not indicate adequate perfusion of the paramedian penetrating branches of the basilar artery or the thalamoperforating branches of the posterior communicating or posterior cerebral arteries. It is these vessels which supply the territory regulating the level of consciousness and containing some of the control mechanisms for respiratory function.

Clinical features of proven basilar artery occlusion.

Our study describes the early symptoms and signs of 85 patients with either basilar artery occlusion or bilateral distal vertebral artery occlusion documented by selective angiography. The most common prodromal symptoms were vertigo, nausea, and headache, which occurred during the 2 weeks before the stroke. Angiographic findings of 49 patients were classified into proximal, middle, and distal b...

Basilar artery occlusion in rats.

The basilar artery is one of the three major sources of blood supply to the circle of Willis. To investigate the effects of basilar artery occlusion, we surgically exposed and coagulated the basilar artery in 25 rats. Basilar artery occlusion at any single point between the foramen magnum and the circle of Willis in 11 rats did not produce histologically detectable infarcts in the brain at 12-2...

Endovascular recanalization of basilar artery occlusion 80 days after symptom onset.

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...

Relationship between findings of conventional and contrast-enhanced transcranial color-coded real-time sonography and angiography in patients with basilar artery occlusion.

BACKGROUND AND PURPOSE Contrast-enhanced transcranial color-coded real-time sonography (TCCS) is a promising tool for the evaluation of brain circulation. The purpose of the present study was to assess the diagnostic ability of conventional and contrast-enhanced TCCS in patients with acute stroke and basilar artery occlusion and to compare the findings with those of angiography. METHODS We pr...

Two cases of basilar artery occlusion in childhood.

Basilar artery occlusion is not a diagnosis which is frequently made, although, since the clarification of the clinical manifestations by Kubik and Adams (1946), more cases are being recognized. The following two cases are reported because no instances of basilar artery occlusion in childhood have been found in the literature, and because in one of the patients the occlusion was a completely is...

CT diagnosis of basilar artery occlusion.

Basilar artery occlusion was diagnosed by high-resolution computed tomography (CT) in 11 cases. The normal basilar artery imaged on plain CT scans has an attenuation value not higher than that of whole blood. If the CT attenuation value of the vessel is higher than that of blood, basilar artery occlusion is probably present. The tentative diagnosis can be confirmed by comparison of the attenuat...
