ABSTRACT

A 74-year-old man who had received graft replacement of ruptured abdominal aortic aneurysm 6 years previously was admitted to our hospital because of hematemesis. Gastroduodenoscopy revealed no bleeding site in the stomach or the first and second portions of the duodenum. Preoperative CT scan demonstrated an adhesion of the aorta-duodenum at the proximal anastomosis of the prosthetic graft. Preoperative angiography demonstrated no leak of contrast material at the proximal anastomosis of the prosthetic graft. Therefore, we performed an emergency operation under a diagnosis of an aortoduodenal fistula. Operative reconstruction was performed with <i>in situ</i> grafting using a new prosthetic graft, and the greater omentum was used to fill defects surrounding the anastomotic site. We report a case of surgical treatment for an anastomotic aneurysm associated with a graft-duodenal fistula after abdominal aortic aneurysm repair.

ABSTRACT

We report a case of surgical treatment of iatrogenic cardiac trauma. A patient with cardiac tamponade was treated by pericardiocentesis. During pericardiocentesis both right and left ventricles were perforated. These perforations were repaired in the beating heart state using 20 monofilament mattress sutures reinforced by felt pledgets. Iatrogenic cardiac trauma is rare. Fatal complications might arise when proper procedures are not followed during the placement of a catheter for pericardiocentesis. Here we present successfull surgical treatment of cardiac penetrations induced by pericardiocentesis.

ABSTRACT

A 59-year-old man had been treated at another institution for bacterial meningitis (<i>Streptococcus pneumoniae</i>). He had severe back pain and lumbago. Computed tomographic (CT) scanning of the chest and abdomen demonstrated saccular aneurysms at the diaphragm in the descending thoracic aorta and the infrarenal abdominal aorta. An extended left posterolateral retroperitoneal incision was performed for resection of the thoracoabdominal aneurysm and replacement of an <i>in situ</i> dacron graft with rifampicin using cardiopulmonary bypass. The abdominal aneurysm was resected and replaced by an <i>in situ</i> dacron graft with rifampicin. The grafts were covered with a pedicled omental flap. The tissue culture was negative. After subsequent intravenous antibiotic therapy for 2 months, the patient was discharged without any evidence of remaining infection.

ABSTRACT

This study was designed to assess the correlation of brain natriuretic peptide (BNP) levels with cardiac function and to determine the usefulness of BNP as a prognostic marker in patients undergoing cardiac valvular surgery. We measured plasma levels of BNP in 53 patients who had undergone aortic valve replacement (AVR) or aortic and mitral valve replacement (DVR) more than 1 year earlier. These cases were divided into the aortic stenosis (AS) group and an aortic regurgitation (AR) group. Fifty-two patients were in NYHA class I, and 43 (82.7%) of them had plasma levels of BNP above the normal range. There were significant correlations between the plasma levels of BNP and ejection fraction (EF) in both the AS and AR groups (<i>r</i>=-0.460, <i>p</i><0.05; <i>r</i>=-0.529, <i>p</i><0.01). In the AR group, BNP showed significant correlations with LVMI and LVDd (<i>r</i>=-0.469, <i>p</i><0.05; <i>r</i>=0.680, <i>p</i><0.0001), whereas, in the AS group, BNP showed no significant correlation with these factors. The most remarkable finding was the development of heart failure in 3 patients whose plasma levels of BNP were over 80pg/ml, despite remaining in NYHA I during follow-up. We concluded that plasma levels of BNP in a late phase after AVR or DVR can be an excellent biochemical marker for predicting of heart failure and overall prognosis.
