Endoconversion During b-EVAR for Pararenal Abdominal Aortic Aneurysm.

Adverse events associated with stent-grafts during complex aortic procedures are rare but can be difficult to manage. These occurrences can be reduced by precise planning and anticipating complications by considering the patient's anatomy and the characteristics of the graft. This paper describes an endovascular conversion following branched endovascular aneurysm repair (b-EVAR) for a pararenal abdominal aortic aneurysm (pAAA) caused by the distal displacement of the stent-graft during delivery system retrieval. A replanned endovascular strategy (endoconversion) was performed by the deployment of another b-EVAR as a bailout technique. Technical success was obtained and the post-operative course and follow-up was uneventful. High technical skills with the ability to predict and manage complications can play a crucial role in the management of intraoperative adverse events.
