Common Iliac Anatomy as a Limiting Factor for the Implantation of Anaconda Aortic Endoprostheses

Introduction: Endovascular Abdominal Aortic Aneurysm Repair (EVAR) remains a challenge for vascular surgeons. There are different models of endografts, including the Anaconda model (Terumo®). Complex iliac anatomy seems to be a risk factor for the appearance of complications after surgery such as endoleaks or branch occlusions. Objectives: To analyse the anatomy of the iliac arteries that receive a distal anchoring of the Anaconda endograft and to determine if it could be a predictive factor for the development of type Ib endoleak. In addition, the study aims to examine the iliac anatomy and its potential relationship to the development of branch occlusion.
