Abstract

An intraarterial shunt for cerebral protection during carotid endarterectomy is described. It combines the features of the U-shaped shunt of Hallin and the straight shunt of Sundt, and incorporates a side-arm that can be used for perfusion, irrigation, and intraarterial pressure. The shunt is a molded Silastic tube with wire coils at each end to prevent collapse, and its funicular collar and rim obviate sudden expulsion. Its use allows endarterectomy to be performed in a deliberate manner, permitting careful attention to prevention of an intimal flap and unhurried repair of the arteriotomy.

摘要

本文描述了一种用于颈动脉内膜切除术期间脑保护的动脉内分流管。它结合了哈林U形分流管和桑特直分流管的特点，并设有一个可用于灌注、冲洗和动脉内压力监测的侧臂。该分流管是一根模制的硅橡胶管，两端带有金属丝线圈以防止塌陷，其缆索状套环和边缘可避免突然排出。使用该分流管可从容地进行内膜切除术，从而能够仔细注意预防内膜瓣形成，并从容地修复动脉切开处。
