Aneurysmectomy with bifurcated graft replacement was initially performed on a patient with a ruptured abdominal aortic aneurysm, and an emergency operation was performed successfully on a proximal anastomosis pseudoaneurysm-rectal fistula that was diagnosed by bloody stool a year after operation. On the 10th postoperative month, CT detected a small pseudoaneurysm at the anastomosed prosthetic aortic graft. On the 1st postoperative year the patient first passed a slight amount of bloody stool, after which there was a large amount of bloody stool. Emergency CT and barium enema showed a pseudoaneurysm extending from near the anastomosed prosthetic aortic graft to the upper margin of the rectum and perforation into the upper rectum (Rs). An abscess covered the prosthetic aortic graft in the pseudoaneurysm, extending to the retroperitonerum on the left. We judged the case to be prosthetic aortic graft infection caused by the abscess and performed an emergency operation. The operation consisted of removal of the bifurcated prosthetic aortic graft, right axillo-bifemoral artery bypass, debridement, lavage, and packaging of the gastrocolic omentum. We report a successfully operated case of prosthetic aortic graft infection caused by pseudoaneurysm, rectal perforation and retroperitoneal abscess.

Blow-out type cardiac rupture after acute myocardial infarction (AMI) is usually a fatal complication. We report the case of a 64-year-old man, admitted to our hospital for AMI with cardiac shock. ECG and echocardiography showed a cardiac rupture after anterior AMI. We performed an emergency operation with a percutaneous cardiopulmonary support system (PCPS) and intra-aortic balloon pumping (IABP). The actively bleeding site, located at the anterior wall, was approximated using a large mattress suture with felt strips to close the rupture site, and the site was covered with fibrin glue. The patient was discharged on POD 48. We report a successful surgery for a case of blow-out type cardiac rupture after AMI.

Floating masses in the descending aorta are an uncommon source of embolism. We report a 43-year-old woman, with no previous history of thrombotic events, who was admitted to our hospital for renal and splenic infarction. Transesophageal echocardiography and computed tomography showed a floating mass in the descending aorta. We started anticoagulant therapy immediately and performed surgical removal of the mass that had caused multiple embolic episodes. The postoperative course was uneventful. In cases of a free floating thrombus in the aorta, it is important to prevent catastrophic complications by removing it surgically after anticoagulant therapy.

During past 7 years, 43 patients less than 2 years of age underwent closure of the ventricular septal defect. Durations of postoperative use of a respirator were 3 days or less in 30 patients (short-period group) and over 3 days in remaining 13 patients (long-period group). There was no operative death. Pre-, intra- and postoperative factors affecting prolonged respiratory care were analyzed between two groups. Results were as follows: There were statistically significant differences between short- and long-period groups on age (9.7 versus 6.5 months), body weight (6.3 versus 5.2kg) at surgery, necessity of preoperative respiratory care on respirator (0/30 versus 4/13), duration of cardiopulmonary bypass (108 versus 132min.), aortic clamp time (56 versus 70min.) and respiratory index at the first postoperative day (1.1 versus 1.7). These results revealed the necessity of far earlier surgical intervention in symptomatic patients before respiratory distress develops. Furthermore, shorter cardiopulmonary bypass and aortic clamp times should always be in mind for attaining smooth postoperative course.
