It is well known that patients with abdominal aortic aneurysms (AAA) have a high incidence of coronary artery disease (CAD), and that the major cause of death in patients undergoing aneurysmectomy is acute myocardial infarction. A total of 53 patients (mean age, 71 years) underwent elective repair of AAA between January 1991 and November 1999. In an attempt to reduce early and late mortality caused by myocardial infarction, coronary angiography (CAG) was performed in all cases. Significant CAD was found in 23 patients (43%), with triple vessel disease in 1 patient (2%), double vessel disease in 5 patients (9%), single vessel disease in 16 patients (30%) and left main in 1 patient (2%). Ten patients (19%) in whom CAD was detected by CAG had no history of CAD and displayed no ischemic findings on ECG. In 4 patients (8%), AAA repair was performed 2 (mean) months after coronary artery bypass grafting (CABG). Percutaneous transluminal coronary angioplasty (PTCA) was performed in 8 patients (23%) 19 days (mean) prior to AAA surgery. No patient had a perioperative myocardial infarction either following coronary revascularization (CABG and PTCA) or AAA resection. Moreover, there was only one operative death after abdominal aneurysmectomy (2%), in a patient who was 70 years old with chronic hemodialysis and who died due to multiple organ failure caused by uncontrollable adhesional ileus. The results of this study emphasize the importance of preoperative routine coronary angiography following coronary artery revascularization to enhance the operative outcome of AAA repair.

We report a case of successful surgical treatment for an aortic anastomotic false aneurysm associated with a graft-duodenal fistula after abdominal aortic aneurysm repair. A 63-year-old man was admitted with melena and an aortic anastomotic false aneurysm after prosthetic graft replacement 8 years previously. CT scan demonstrated an aneurysm with a maximum diameter of 70mm at the proximal anastomotis of the prosthetic graft. Gastroduodenoscopy revealed no bleeding site in the stomach or the first and second portions of the duodenum. Therefore, we performed an emergency operation under a diagnosis of an aortic anastomotic false aneurysm associated with a graft-duodenal fistula. The aneurysm was replaced with interposition of a new prosthetic graft via a thoracoabdominal approach. The fistula was repaired by covering the duodenum with the jejunum through a left pararectal laparotomy. The postoperative course was uneventful, and there was no evidence of graft infection at 14 months after the operation.

Rheumatic tricuspid stenosis has become rare recently. A 54-year-old woman had undergone mitral valve replacement with a Carpentier-Edwards bioprosthesis for mitral stenosis 22 years previously and had undergone repeat mitral valve replacement for prosthetic valve failure 10 years later. She was admitted with severe leg edema. Cardiac catheterization revealed pulmonary hypertension and tricuspid stenosis with a diastolic pressure gradient of 6mmHg across the tricuspid valve. Tricuspid valve replacement was performed with a Hancock bioprosthesis. The postoperative course was uneventful and her edema improved markedly. This case suggested that careful follow-up to detect progression of tricuspid stenosis is necessary in patients with rheumatic valve disease and pulmonary hypertension.

Purpose: Despite widespread adoption of open abdominal management (OAM), there is currently no threshold criterion for OAM duration for non-trauma patients. Moreover, there is a positive relationship between morbidity and the duration of OAM, but an uncertain relationship with patients’ age. Therefore, a novel clinical index for the duration of open abdominal management (IDOM) was developed based on the patient’s age and risk of severe complications following OAM to indicate the maximum tolerable number of days of OAM based on the individual’s age. The utility of this new index was evaluated. Methods: This retrospective study included 65 non-trauma patients managed with an open abdomen (OA) from August 2015 to August 2018. The IDOM was developed based on the patient’s age. The result indicated the maximum number of OA days. Patients’ demographic and operative variables were examined and patient data was assigned to one of two groups according to whether the actual number of OA days was above or below the calculated IDOM. Prevalence of complications between these groups was compared. Measures of validity were employed to assess the utility of the IDOM for patient complications. Results: Sixty-five patients were included. The above-the calculated IDOM group exhibited a significantly longer OA and higher rates of wound complications and postoperative respiratory complications compared with the below the calculated IDOM group. The IDOM predicted the incidence of OA-related complications with a sensitivity of 72.4%, and a specificity of 80.6%. Conclusion The IDOM is a potentially useful tool for appropriate duration at the outset of OA.
