Three patients with giant aneurysms (2 internal carotid and 1 anterior communicating) were treated by internal carotid occlusion with a detachable balloon. 133Xe regional cerebral blood flow (rCBF) was performed on each patient on admission. Due to low CBF, one patient received a superficial temporal artery--middle cerebral artery (STA-MCA) bypass. The rCBF was repeated when the balloon was inflated in the internal carotid prior to detachment of the balloon. All three patients were discharged within one week with no neurologic deficit. The rCBF assessment appears useful to decide which patient will tolerate acute balloon occlusion of the internal carotid and to help select patients who will need an extra-cranial-intracranial (EC-IC) bypass to avoid ischemic complication.
3例巨大动脉瘤患者（2例颈内动脉瘤和1例前交通动脉瘤）接受了可脱性球囊颈内动脉闭塞治疗。每位患者入院时均进行了¹³³Xe局部脑血流量（rCBF）测定。由于脑血流量低，1例患者接受了颞浅动脉-大脑中动脉（STA-MCA）搭桥手术。在球囊脱离前向颈内动脉内充盈球囊时重复进行rCBF测定。所有3例患者均在1周内出院，无神经功能缺损。rCBF评估似乎有助于确定哪些患者能够耐受颈内动脉急性球囊闭塞，并有助于选择需要进行颅外-颅内（EC-IC）搭桥手术以避免缺血性并发症的患者。
