Endovascular treatment of distally located giant aneurysms.

摘要: OBJECTIVE Because giant aneurysms (GAs) can be technically difficult to clip, the endovascular approach is becoming increasingly popular. Endovascular treatment of distally located GAs, which often requires parent vessel occlusion, particularly challenging because limited pathways are available for collateral flow. We aimed determine outcomes attempts treat GAs downstream from circle Willis. METHODS Between 1991 and 1998, 27 patients with very large or were evaluated possible treatment. Ten underwent selective embolization 9 treated primary without distal bypass. Eight could not endovascularly. RESULTS Selective resulted in only one cure. Two died as a result subarachnoid hemorrhage during follow-up period. One coil-treated patient, who subsequent spontaneous all nine primarily occlusion considered cured after their treatments. Only two experienced periprocedural ischemia, did major deficit either case. Of eight endovascularly, succumbed surgery, four while being conservatively, three lost monitoring. CONCLUSION aneurysm usually curative these situations. For selected patients, however, safe effective preventing progression symptoms bleeding.
