Microsurgical treatment of basilar tip aneurysms: is it still acceptable?

Blood Flow Into Basilar Tip Aneurysms

Endovascular coil embolization is an established treatment for intracranial aneurysms. The efficacy of coil embolization has been proven for the prevention of rebleeding in the acute phase of aneurysmal subarachnoid hemorrhage. Endovascular coil embolization is occasionally preferred in the management of unruptured intracranial aneurysms because it is less invasive than surgical clipping. Howev...

Basilar Tip Aneurysm : Endovascular Treatment

RESULTS: Embolization was technically successful in all patients. Cornplete occlusion was achieved in 14 (67%) patients; 90% occlusion was achieved in seven (33%) patients. There was partial reperfusion of the aneurysm in three patients (14%) after 6 months, which necessitated repeated embolization. The clinical results were excellent in 13 patients, good in six, and fair in one. One patient di...

Thrombosis in giant basilar tip aneurysms during coil embolization.

Two patients with giant basilar tip aneurysms underwent coil embolization, one with both platinum fiber and platinum Guglielmi detachable coils and the other with Guglielmi detachable coils only. In both cases, spontaneous intraaneurysmal thrombosis occurred outside the coil mass, presumably a result of disruption of the intraaneurysmal flow pattern.

Endovascular treatment of basilar tip aneurysms after direct puncture of the vertebral artery.

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...
