Internal cuff reimplantation technique for aortic branch reconstruction.

Abstract

Massive blood loss during thoracoabdominal aortic aneurysm repair may impair postoperative outcomes but can be reduced by a secure suture line. Our internal cuff reimplantation is a novel technique for the reconstruction of branch arteries with a cuff of the native aortic wall, which is anastomosed inside the prosthesis through a hole created in it. This technique can ensure hemostasis at the anastomosis by decompression of the suture line, improve patency of the reconstructed branches by leaving the diseased orifices untouched, and prevent future enlargement of the remnant native aortic wall by covering it with the prosthesis.
