Abstract
Rete mirabile is a congenital aberrant arterial collateral network resulting from abnormal embryonic activity during native vessel formation. Even though frequently observed in mammals, this entity is rare in humans except when there is hypoplasia, aplasia or narrowing of native vessels. Rete mirabile is reported involving internal carotid and vertebral arteries. Rete mirabile of the posterior inferior cerebellar artery (PICA) is not described in the literature. We report the clinical presentation, imaging findings and management of PICA rete mirabile formation with subarachnoid hemorrhage.
摘要
奇网是一种先天性异常动脉侧支网络，由正常血管形成过程中异常的胚胎活动所致。尽管在哺乳动物中经常观察到，但该实体在人类中很少见，除非存在正常血管发育不全、发育不全或狭窄。据报道，奇网累及颈内动脉和椎动脉。文献中未描述小脑后下动脉（PICA）的奇网。我们报告了伴有蛛网膜下腔出血的PICA奇网形成的临床表现、影像学表现及治疗方法。
