Transcaval Access to the Abdominal Aorta: indications of Interest to Surgeons and a Comprehensive Literature Review

Abstract We performed a review of the literature (until August 01, 2019) on the occasion of the first transcaval approach for transcatheter aortic valve implantation in our hospital. This review focuses mainly on the indications of this alternative access route to the aorta. It may be useful for vascular surgeons in selected cases, such as the treatment of endoleaks after endovascular aneurysm repair and thoracic endovascular aneurysm repair. We describe historical aspects of transcaval access to the aorta, experimental studies, available case series and outcomes. Finally, we summarize the most significant technical aspects of this little-known access.

摘要：值本院首例经腔静脉入路行经导管主动脉瓣植入术之际，我们对截至2019年8月1日的相关文献进行了系统回顾。本综述重点阐述该主动脉替代入路的临床适应证。该入路在特定临床病例中对血管外科医师具有参考价值，例如血管腔内动脉瘤修复术（endovascular aneurysm repair, EVAR）及胸主动脉腔内修复术（thoracic endovascular aneurysm repair, TEVAR）术后内漏的治疗。本文详述了经腔静脉主动脉入路的历史沿革、相关实验研究、现有病例系列研究及临床结局。最后，本文总结了这一鲜为人知的入路的核心技术要点。
