Two Cases of Graft Replacement Combined with Wrapping Procedure for Thoracoabdominal Aortic Aneurvsm / 日本心臓血管外科学会雑誌

ABSTRACT

The results of complete graft replacement for thoracoabdominal aortic aneurysm remains unsatisfactory. The operative strategies, including the method of reconstruction of visceral vessels and the protection of abdominal organs and spinal cord, are controversial. Two male patients (53 and 59 years of age) had thoracoabdominal aortic aneurysms including the celiac artery and small abdominal aortic aneurysm in the renal arterial part. They underwent replacement of a large aneurysm using a Dacron prosthesis with reconstruction of the celiac artery. The remaining small aneurysm was wrapped by a bandage of Teflon tape 3mm in width. This wrapping technique was easy to perform and could be sufficiently adapted to the aneurysm preserving visceral arterial branches. The postoperative courses were uneventful. Their postoperative enhanced CTs (41 months and 26 months after surgery, respectively) revealed no enlargement of the wrapped aortic aneurysm and no stenosis of the visceral branches. This result suggests that our wrapping method is useful to reinforce the wall of small aortic aneurysms.
