We present the case of a 68-year-old woman with abdominal aortic aneurysm (AAA) complicated by right ectopic kidney, in another term, congenital pelvic kidney. The patient underwent AAA repair and right renal artery reconstruction using renal perfusion with cold Ringer's acetate, and no deterioration of renal function was observed. 3D-CT was essential diagnostic procedure in order to identify the blood supply to the ectopic kidney for planning a careful surgical technique.

A 72-year-old woman was admitted with a sensation of compression and shortness of breath. A mass was detected in the right atrium (RA) by transthoracic echocardiography. Preoperative chest computed tomography showed an RA tumor measuring 30×24 mm in the lateral wall. We performed resection under the cardiopulmonary bypass. Histopathological examination confirmed that this tumor was a lipoma.

Between 1988 and 1991, 231 patients underwent surgical repair for abdominal aortic aneurysm. Among them 132 patients underwent isolated Y graft replacement electively. They were divided into two groups, according to the operative procedure; transperitoneal approach (n=51) and retroperitoneal approach (n=81), and the surgical results were compared retrospectively. There was no significant difference in operative time, amount of operative bleeding, operative transfusion, total transfusion, autotransfusion, duration of intubation, total use of analgesia or length of postoperative stay in the two groups. The amount of fluid drained from the nasogastric tube was significantly greater in the transperitoneal group. The initiation of drinking and eating were both significantly prolonged in the transperitoneal group. The transperitoneal approach is indicated for cases with thoracic or thoracoabdominal aneurysm which may be operated on in the future, cases of bilateral common iliac aneurysms and cases with heart disease. Otherwise it is preferable to select the retroperitoneal approach as the first choice for elective surgical treatment of abdominal aortic aneurysm, because the retroperitoneal approach is superior in terms of the recovery of gastro-intestinal movement.
