A patient with a giant aneurysm of the top of the basilar artery presented with severe progressive symptoms of brain-stem compression. There was inadequate collateral circulation to the upper basilar system. She underwent exploration of the aneurysm and, after it was found to be impossible to clip, a tourniquet was placed on the basilar artery for future occlusion with the patient awake. A saphenous vein graft was interposed between the left external carotid and the left posterior cerebral arteries. The previously unruptured aneurysm bled fatally 36 hours after surgery, just before intended occlusion of the basilar artery.
一名患有基底动脉顶端巨大动脉瘤的患者出现了严重的进行性脑干压迫症状。基底动脉上段的侧支循环不足。她接受了动脉瘤探查，发现无法夹闭后，在基底动脉上放置了止血带，以便在患者清醒时进行未来的闭塞。在左颈外动脉和左大脑后动脉之间置入了大隐静脉移植物。此前未破裂的动脉瘤在手术后36小时，即在预定闭塞基底动脉之前，发生致命性出血。
