A Successful Surgical Repair of Anastomotic Aneurysm Complicated with Aorto-renal Bypass 31 Years after the Initial Operation / 日本心臓血管外科学会雑誌

ABSTRACT

A 55-year-old man was admitted with anterior chest pain. He had received aorto-renal bypass for left renal artery stenosis at the age of 24. His coronary angiography with ergotamine malate provocation showed 99% stenosis in the left anterior descending artery and circumflex artery and abdominal aortography revealed an aneurysm with a diameter of 4cm at the proximal site of the graft anastomosis. The patient was surgically treated with aneurysmectomy and PTFE grafting (7mm) between abdominal aorta and the already-implanted graft to the left renal artery. His postoperative course was uneventful and no major complication such as renal failure were observed. Anastomotic aneurysm is a fairly common complication associated with arterial reconstruction which is most common in the common femoral artery. This is the first reported case of anastomotic aneurysm complicated by aorto-renal bypass.
