摘要
本文对36例颈动脉结扎术或孤立术治疗的颅内动脉瘤和颈内动脉海绵窦瘘患者于术后4~11年进行结扎对侧的颈动脉造影随访,其中 7例发现新生动脉瘤,发病率为 19%,显著高于一般颅内动脉瘤的发病率。本组新生动脉瘤皆位于结扎对侧颈内动脉后交通动脉起始部(ICA)。而全部病例曾于颈动脉结扎术前行双侧颈动脉造影,未发现该侧有动脉瘤迹象。随访结果表明:一侧颈动脉结扎可诱发对侧颅内动脉瘤,大多在术后7~10年出现,从临床上进一步说明,脑血流动力学变化对颅内动脉瘤形成有重要影响。
Angiographic follow-up studies on 36 patients4~11 years after carotid ligation for intracranialaneurysms or carotid-cavernous fistulas have beenmade. New aneurysms were found in 7 cases. Theincidence of 19% (7 of 36 cases) was much high-er than the estimated incidence of intracranialaneurysms in the general population (1%). Allof these new aneurysms were locatedat the junction of internal carotid and posteriorcommunicating artery on the nonligation side, whereno trace of aneurysms had been found on angiographyperformed bofore carotid ligation. This data suggeststhat the cerebral hemodynamic changes secondaryto carotid ligation played an important role in theformation of intracranial aneurysms.
