Case reports to analyze causes and possible prevention of complications in a new setting are important. We present an open repair of a ruptured type 2 thoracoabdominal aortic aneurysm in a 78-year-old man. Lower-body perfusion through a temporary extracorporeal axillobifemoral arterial prosthesis shunt was combined with the use of a branch to the permanent aortic prosthesis to enable rapid visceral revascularization using a visceral-anastomosis-first approach. The patient died due to transfusion-induced capillary leak syndrome and left colon necrosis; the latter was probably caused by a combination of back-bleeding from lumbar arteries causing a steal effect, an accidental shunt obstruction, and hemodynamic instability towards the end of the operation. The visceral-anastomosis-first approach did not contribute to the complications. This approach reduces the time when visceral organs are perfused only via collateral arteries to the time needed for suturing the visceral anastomoses. This may be important when collateral perfusion is marginal.
分析新环境下并发症原因及可能预防措施的病例报告很重要。我们报告了一例78岁男性2型胸腹主动脉瘤破裂的开放修复手术。通过临时体外腋双股动脉人工血管分流进行下半身灌注,并结合使用分支连接永久性主动脉人工血管,采用先进行内脏吻合的方法实现快速内脏血管重建。患者因输血引起的毛细血管渗漏综合征和左结肠坏死死亡;后者可能是由于腰动脉回血导致盗血效应、意外分流阻塞以及手术末期血流动力学不稳定共同作用所致。先进行内脏吻合的方法与并发症无关。这种方法将内脏器官仅通过侧支动脉灌注的时间缩短至缝合内脏吻合所需的时间。当侧支灌注不足时,这可能很重要。
