胸腹主动脉瘤的外科治疗进展

Surgical treatment of thoracoabdominal aortic aneurysm

胸腹主动脉瘤(TAAA)是一种累及降主动脉及腹主动脉的动脉瘤样变,自然病程病死率高,手术治疗难度大。传统的治疗方式为开放手术,随着腔内技术的发展,杂交手术和以开窗支架和分支支架为代表的腔内手术技术在TAAA治疗方面展现出了价值,新近出现的八爪鱼技术进一步完善了腔内治疗的术式选择,TAAA的微创治疗正逐步成为可能。

Thoracoabdominal aortic aneurysm （TAAA） refers to an abnormal widening of the aorta involving both its descending and abdominal segments. It is a highly lethal condition as far as its natural history is concerned and the surgical intervention is difficult to perform. Open surgery is the traditional method for TAAA repair, but with the development of endoscopic technology, hybrid surgery and endovascular therapy represented by fenestrated or branched stent grafts are already showing great promise in treatment of TAAA, and the newly developed octopus technique further enriched the choice of its endovascular therapy. Minimally invasive treatment of TAAA is now gradually becoming possible.
