摘要
脉络膜前动脉动脉瘤临床上较少见,发生率占颅内动脉瘤的2%~5%,破裂率为26.7%。由于脉络膜前动脉管径相对狭小、解剖结构复杂、手术夹闭治疗难度大、风险高,且术后并发症较常见。其中,最常见的并发症为脉络膜前动脉狭窄或闭塞造成的脉络膜前动脉综合征,严重影响患者神经功能的恢复。本文拟通过文献回顾,对脉络膜前动脉动脉瘤夹闭术后缺血并发症的诱因及预防保护措施进行综述。
Anterior choroidal artery aneurysms(ACh AAs)are rare in clinic,accounting for 2% to 5% of all intracranial aneurysms,and the rupture rate is 26.7%. Because of the complex anatomical structure and the relatively smaller diameter of the anterior choroidal artery(Ach A),the surgical operation is difficult and high-risked. Often the postoperative complications are present,among which,the most common one is the ACh A syndrome caused by the stenosis or obstruction of the ACh A. The syndrome can severely affect the post-operative recovery of patients' neurological functions. Through reviewing the previous literature,this study aimed at making a clue for the inducing factors of clip-induced ischemic complications of ACh AAs and their prevention approaches.
