Both atrial resection and superior vena cava replacement in sleeve pneumonectomy for advanced lung cancer

Both atrial resection and superior vena cava replacement in sleeve pneumonectomy for advanced... Abstract Extended sleeve pneumonectomy including removal of the superior vena cava, right atrium and parts of left atrium on cardiopulmonary bypass was successfully performed in a 40-year-old man. The tumour was histologically proven a T4 N1 stage with margins free from tumour. Adjuvant radiochemotherapy was administered postoperatively on an outpatient base. The patient did well for 7 months then he died from myocardial infarction due to metastatic infiltration of the right coronary artery. Other metastatic deposits were not found at autopsy. More data from extended pulmonary resections are required to demonstrate a benefit. Advanced lung cancer, Extended pulmonary resection, Cardiopulmonary bypass Results A 40-year-old-man complained of cough and hemoptysis of 2 months duration. He smoked two packs of cigarettes per day for 25 years. Chest X-ray films showed a mass in the right upper lobe invading the mediastinum. Computed tomography of the thorax (CT) revealed tumour invasion of the carina and superior vena cava (SVC) (Fig. 1 ). Enlarged lymph nodes were not found. Biopsy taken bronchoscopically from the right main bronchus showed a squamous cell carcinoma. Metastases were ruled out by abdominal CT and bone scintigraphy. The patient was deemed to be in an excellent clinical condition for primary resection. Operative access was achieved by right posterolateral thoracotomy. Invasion of the mediastinum was found more advanced than preoperatively expected: the tumour extended into the right heart by continuity. As there was no evidence of malignant pleural effusion nor for pleural carcinosis we decided to put the patient on cardiopulmonary bypass by cannulating superior and inferior vena cava, as well as the ascending aorta. Blood cardioplegia was employed and the right atrium entered anteriorly. The interatrial septum and the confluence of the superior and inferior pulmonal veins were invaded as well. Resection comprised three quarters of the right atrium, a 5-cm long segment of the SVC and a quarter of the left atrium. The right main pulmonary artery was dissected and centrally stapled by a TA 30 vascular stapling device and divided. The resection was accomplished by division of the distal trachea one ring above the carina and the left main bronchus one ring below. Fig. 2 shows the intraoperative situs when resection was completed. The specimen showed the real extension of the tumour; frozen section of the resection margins were free of tumour. Reconstruction began with the end-to-end anastomosis of the trachea and left main bronchus with interrupted monofilamentous sutures PDS 3-0. The anastomosis was secured by a pedunculated intercostal muscle flap which was wrapped around the sutures and fixed by fibrin glue. A gelatine coated 18 mm dacron prosthesis was interposed in the caval and right atrial defect (Fig. 3 ). The left atrial defect was closed by continuous suture. A temporary pacemaker (Fig. 3) was administered and the pericardial defect closed by a Goretex patch. The patient could then be easily weaned from cardiopulmonary bypass. One chest tube was inserted on the right side and removed 2 days later. The postoperative course was complicated by a pneumonia. However, the patient recovered well under antibiotic therapy and was discharged on the 25th day after operation. Histologically the margins were free from tumour and lymph node metastasis found in the first level representing a T4 N1 M0 stage.
