Abstract

Hybrid repair of a thoracoabdominal aortic aneurysm comprising thoracic endovascular aortic repair and total renovisceral debranching is a feasible alternative to open repair, especially for high-risk patients. However, transperitoneal debranching is a relatively complicated procedure that requires deep dissection around vital abdominal organs. Therefore, we developed a new debranching technique called Chunnel debranching, which was characterized by transaortic tunneling using a covered stent between the target artery and the prosthetic graft anastomosed on the aneurysmal wall using an inclusion technique. This procedure increases the feasibility of renovisceral debranching with fewer dissections than conventional transperitoneal debranching.
