Left pneumonectomy for lung cancer after correction of contralateral partial anomalous pulmonary venous return.

We report the successful treatment of a 48-year-old man with left lung cancer and contralateral partial anomalous pulmonary venous return (PAPVR). He was found to have an abnormal shadow on a regular checkup. Sputum cytology revealed squamous cell carcinoma. Chest computed tomography showed not only a left hilar mass but also showed that his right superior pulmonary vein was draining into the high portion of the superior vena cava. In the presence of the right partial anomalous pulmonary venous return, it was believed that left pneumonectomy would cause serious postoperative heart failure due to an increase in the left-to-right shunt. Therefore his partial anomalous pulmonary venous return was corrected first under cardiopulmonary bypass, and 3 weeks later he underwent successful radical left pneumonectomy.

Multiple atherosclerotic aneurysms of the bilateral subclavian artery, aortic arch and abdominal aorta.

Subclavian artery aneurysms are relatively rare in comparison with other peripheral aneurysms. We report a 65-year-old woman with multiple atherosclerotic aneurysms of the subclavian artery, aortic arch saccular aneurysm and abdominal aortic aneurysm. Two-staged operations by which the infrarenal abdominal aorta was replaced first and median sternotomy extending to the supraclavicular space for the concomitant resection of bilateral subclavian as well as aortic arch aneurysm resulted in good results.

[Acute infective endocarditis].

Between January 1987 and June 2004, 65 patients with infective endocarditis underwent aortic and/or mitral surgery. Nine of these patients with active native valve endocarditis required emergency surgery. Indications for emergency operation were progressive congestive heart failure in 5 patients, systemic emboli in 2 patients and uncontrolled infection in 2 patients. The aortic valve was affected in 3 patients, the mitral valve in 4 patients and both the aortic and mitral valve in 2 patients. All of these patients were treated with radical excision of infected tissue and implantation of mechanical or stented bioprosthetic valves. There was no hospital death and no patients required reoperation for recurrent endocarditis. Although medical therapy for acute infective endocarditis is effective in most instances, some patients still require early surgical intervention. These data demonstrate excellent results in patients who underwent emergency surgery for acute infective endocarditis.

False aneurysm due to suture loosening after aortic arch replacement.

We describe a case of false aneurysm due to loosening of the anastomotic sutures 5 years after graft replacement for subacute type A aortic dissection. Leakage from the graft was controlled by tightening the suture slack indicating that suture loosening was the cause of the aneurysm. The mechanism was probably the progressive thinning of the edematous swollen aortic wall over the years causing the sutures to loosen.

Resection of paraaortic lymph node metastasis of colon cancer with graft replacement.

The metastasis sites of colon cancer are the liver, lungs, bones, peritoneum, and lymph nodes. Lymph node recurrences, however, are seldom resected metachronously. We report here a case of en-bloc resection of paraaortic lymph node recurrence together with the invaded abdominal aorta, left kidney and ureter 4 years after curative resection of sigmoid colon cancer. Combined resection of the metastatic lymph nodes and the abdominal aorta would be an even more radical procedure and treatment for cancer because of lymphatic spread around the aorta. The slow growth of the cancer might justify this aggressive resection. This is the first report of resection of late paraaortic lymph node metastasis and simultaneous abdominal aortic graft replacement.
