颈内动脉球囊闭塞试验（BOT）和可脱性球囊永久性闭塞治疗的临床应用价值分析

目的对于Mata＇s试验（颈动脉压迫试验）阴性的颈内动脉宽颈动脉瘤、梭形动脉瘤、巨大动脉瘤（GA）、海绵窦动脉瘤、海绵窦瘘（CCF）、前循环供血肿瘤等患者行颈内动脉球囊闭塞试验（BOT）,评估其安全性;BOT阴性者行颈内动脉可脱性球囊永久性闭塞治疗,分析其临床应用价值。方法 43例颈内动脉（ICA）上述患者,应用可脱性球囊暂时性闭塞ICA,作BOT,36例BOT阴性患者行永久性闭塞ICA,观察其脑缺血并发症的发生率。结果 BOT的阴性率为83.7%。随访3～6个月统计,与BOT相关的并发症的发生率为8.3%。可脱性球囊永久性闭塞ICA后脑缺血的发病率为2.8%。结论 BOT是检测患者是否耐受ICA闭塞安全有效的方法,颈内动脉可脱性球囊永久性闭塞是治疗颈内动脉宽颈动脉瘤、梭形动脉瘤、巨大动脉瘤（GA）、海绵窦动脉瘤、海绵窦瘘（CCF）、前循环供血肿瘤的有效方法。

Clinical application analysis on balloon occlusion test (BOT) and permanent ICA occlusion with balloon which can be taken off

Qbjective To estimate the safety of balloon occlusion test（BOT） of internal carotid artery（ICA）,which with a negative result on Mata＇s test.Include ICA wide-necked aneurysms,fusiform aneurysm,giant aneurysms（GA）,cavernous sinus aneurysms,carotid cavernous fistulas（CCF） and intracranial tumour blood-supplied by front circle.To analysis the clinical application value of internal carotid artery cured by permanent balloon occlusion,which with a negative result on BOT.Methods Tentatively block internal carotid artery with balloon which can be taken off in 43 cases accompanied above-mentioned lesions.36 cases had negative results.Meantime,observed the incidence of complications of cerebral ischemia.Results The negative rate of BOT is 83.7%.Follow-up of 3 to 6 months,complications associated with the incidence of BOT is 8.3%.The incidence of cerebral ischemia associated with permanent balloon occlusion is 2.8%.Conclusion BOT is a safe and effective testing could detect whether patients to tolerate permanent balloon occlusion.Permanent occlusion with balloon which can be taken off is a effective method on treatment of ICA wide-necked aneurysms,fusiform aneurysm,giant aneurysms（GA）,cavernous sinus aneurysms,carotid cavernous fistulas（CCF） and intracranial tumour blood-supplied by front circle.
