Abstract

Pseudoaneurysms of the ascending aorta developing after previous aortic or aortic valve surgery pose a high risk of exsanguination upon sternal reentry. In the past, femorofemoral bypass and hypothermic circulatory arrest before sternotomy was the preferred approach. Today, however, availability of the PORT-ACCESS EndoCPB system (Edwards Lifesciences, Irvine, CA, USA) allows for endovascular clamping and cardioplegia before sternotomy, avoiding circulatory arrest.

摘要

既往主动脉或主动脉瓣手术后发生的升主动脉假性动脉瘤，在再次开胸时存在大出血的高风险。过去，在胸骨切开术前采用股-股旁路和低温循环停止是首选方法。然而如今，PORT-ACCESS体外循环系统（美国加利福尼亚州尔湾市爱德华兹生命科学公司）的应用使得在胸骨切开术前能够进行血管内钳夹和心脏停搏，从而避免循环停止。
