Chest wall invasion in carcinoma of the lung. Therapeutic and prognostic implications.
From 1974 through 1983, 125 patients underwent operation at Memorial Sloan-Kettering Cancer Center for non-small cell carcinoma of the lung invading the chest wall. (Excluded are those with superior sulcus tumors or distant metastases at presentation.) Eighty patients were male and 45 were female. Ages ranged from 33 to 88 years (median 60 years). Histologically, the tumors were epidermoid carcinoma in 46%, adenocarcinoma in 46%, and large cell carcinoma in 8%. ⋯ The extent of tumor invasion of the chest wall appeared to influence survival, but in the absence of lymphatic metastases the difference at 5 years was not significant. Complete resection offers a significant chance for long-term survival in lung cancer directly extending into parietal pleura and chest wall. Extrapleural resection or en bloc chest wall resection can be performed with a low operative mortality and an expected 5 year survival in excess of 50% in the absence of lymphatic metastases.

Randomized Controlled Trial Comparative Study Clinical TrialA prospective randomized study of hydroxyethyl starch, albumin, and lactated Ringer's solution as priming fluid for cardiopulmonary bypass.
The ideal priming fluid for cardiopulmonary bypass is not known. We designed a study to determine whether there are important differences in the clinical effects of hydroxyethyl starch versus albumin when used in priming fluid, and in the clinical effects of colloid versus crystalloid priming fluid. We prospectively randomized 83 adult patients undergoing coronary artery bypass or valve replacement. ⋯ No adverse reaction to the prime solutions was noted. The differences between the HES and ALB groups--prothrombin time, platelet count, and blood viscosity--had no apparent clinical effects; thus, the two may be considered clinically equivalent. The greater somatic and pulmonary fluid accumulation in the LRS group suggests that colloid is preferable to crystalloid in priming fluid.

Cardiovascular and thoracic battle injuries in the Lebanon War. Analysis of 3,000 personal cases.
This report comprises 3,000 casualties of the Lebanon War whom I operated upon for cardiovascular-thoracic injuries in twelve Lebanese hospitals between January, 1969, and July, 1982. These patients were studied retrospectively through 1978 and prospectively thereafter. The logistics, weapons, wounds, and operative results in this study were unique. ⋯ The mortality for injury to the aorta was 60% (12 deaths), contrasted with 1% (three deaths) for injury to extremity vessels. Hemorrhage and cardiac rupture were the most frequent causes of death. Early, proficient, open surgical control after or concomitant with intensive resuscitation proved successful in this special military conflict.

Comparative StudyIn vivo hemodynamic comparison of porcine and pericardial valves.
The bovine pericardial valve and the SupraAnnular valve have been developed to improve the hemodynamic function of tissue valves. Hemodynamic performances of the standard Carpentier-Edwards porcine valve, the Carpentier-Edwards SupraAnnular valve, and the Carpentier-Edwards bovine pericardial valve were compared in the aortic position. One hundred patients undergoing aortic valve replacement were studied intraoperatively. ⋯ At the same flow rate, the 23 mm pericardial valve had larger valve orifice areas, higher performance indices, and lower gradients than the 23 mm SupraAnnular valve. The SupraAnnular valve is hemodynamically superior to the standard Carpentier-Edwards porcine bioprosthesis. The Carpentier-Edwards pericardial valve, however, is less obstructive in the aortic position than either of the porcine valves.

Modified Blalock-Taussig shunt in infants and young children. Clinical and catheterization assessment.
The effectiveness of 19 modified Blalock-Taussig shunts performed with expanded polytetrafluoroethylene was evaluated clinically and by cardiac catheterization with angiography 4 to 24 months after operation. Fifteen patients underwent operation in infancy. Conduit diameters included 4 mm (nine cases), 5 mm (eight cases), and 6 mm (two cases) sizes. ⋯ There were no deaths. Thirteen children underwent more complete elective cardiac repair 5 to 24 months later. Although the modified Blalock-Taussig procedure is an effective short-term alternative to the classic Blalock-Taussig shunt, the effectiveness of the 4 mm diameter conduit may be limited without postoperative anticoagulant therapy.
