Endosaccular occlusion of basilar artery bifurcation aneurysms using electrically detachable coils.

摘要: Thirteen patients with basilar artery bifurcation aneurysms, treated by electrothrombosis using electrically detachable coils, are presented. Nine of them presented after hemorrhage, two mass effect, and were found coincidentally other ruptured aneurysms. Selection for endovascular therapy was based on the following criteria: 1) poor clinical condition (Hunt Hess III-V); 2) high surgical risk; 3) age medical condition; 4) morphological features (small necked aneurysms). With Guglielmi coils aneurysm occlusion ranging from 70-100% achieved in all cases. All five small large broad aneurysms totally occluded. Two had a 95% 90% In another patient only an 80% achieved, because tortuosity vertebrobasilar system. Our last patient, who as grade V clinically, partially 70% aneurysmal occlusion.
