Results of unifocalization for pulmonary atresia, ventricular septal defect and major aortopulmonary collateral arteries: patency of pulmonary vascular segments.
Unifocalization, a surgical technique to unifocalize the pulmonary blood supply in patients with pulmonary atresia, ventricular septal defect and major aortopulmonary collateral arteries, is a useful preparative operation to extend the indication for corrective surgery. The preoperative and postoperative pulmonary angiograms of 51 patients (aged 3 months-26 years at first unifocalization, 29 males, 22 females), who underwent a total of 96 unifocalizations from December 1985 to July 1994, were studied to assess the effectiveness of each procedure of unifocalization. The procedures of unifocalization were ligation (9), angioplasty (6), direct anastomosis (25), bridging (6), additional central pulmonary artery creation (9), central pulmonary artery creation (36) and thrombectomy (5). ⋯ S.). The patency rate of the anastomoses involving intrahilar arteries was 88.0% (44/50), while that for the group involving extrahilar arteries only was 71.9% (46/64; P < 0.05). It is concluded that 1) unifocalization with the reconstruction of central pulmonary arteries using a pericardial roll is a useful method for patients with absent or hypoplastic central pulmonary arteries, 2) it is preferable to divide the fissures of lung in anastomosing pulmonary arteries of arborization abnormalities.

Predictive factors for postoperative cerebral complications in patients with thoracic aortic aneurysm.
Perioperative factors affecting the outcomes of postoperative brain function in patients with thoracic aortic aneurysm were demonstrated. ⋯ Although there was an increased incidence of advanced age and complex lesions in patients with aortic aneurysm, an improvement in surgical results has recently been achieved using advanced diagnostic and surgical techniques.

Aortic root replacement with a composite graft. Factors influencing immediate and long-term results.
From April 73 to June 94, 203 patients (167 men, 36 women) aged from 10 to 74 years (mean: 44.8 +/- 15) underwent ascending aortic replacement with composite graft for: dystrophic aneurysm (AN) (130 cases, 64.5%), chronic dissection (CD) (35 cases, 17.2%), type A acute dissection (AD) (38 cases, 18.7%). Forty-six patients (22.6%) suffered from Marfan syndrome (24 AN, 13 AD, 9 CD). Thirty patients (14.7%) had undergone a previous cardiac or aortic operation. ⋯ The technique of coronary reimplantation has a significant influence on the long-term results. The reimplantation of choice is the "button" technique, especially in the presence of a fragile aortic wall (AD). The "Cabrol" technique must be used when the "button" or the "Bentall" reimplantation is not feasible, for instance during redo procedures.

Since 1990 the Institute of Cardiac Survey has compiled data on open heart surgery. In 1993 247,943 operations were performed. ⋯ This subset was 1.9%, e.g. 4,689, of the total number. The increasing rate of open heart surgery in Europe was 8.3%, whereby the highest increasing rate could be observed in CABG.

Respiratory muscle strength after lung resection with special reference to age and procedures of thoracotomy.
Changes in respiratory muscle strength after lung resection were examined concerning age and procedures of thoracotomy. Maximum inspiratory (MIP) and expiratory (MEP) mouth pressure were measured before operation and 1, 2, 4, and 12 weeks after operation in 81 patients undergoing lung resection. In 48 patients undergoing pneumonectomy, lobectomy, or segmentectomy, patients older than 70 showed a significantly lower MIP and MEP before operation and throughout the postoperative period compared to younger ones (P < 0.01). ⋯ In 31 patients undergoing lung wedge resection, patients undergoing limited thoracotomy (LT) and video-assisted thoracic surgery (VATS) showed significantly higher percentages of postoperative MIP and MEP than those undergoing posterolateral thoracotomy (PLT) 1 and 2 weeks after operation (P < 0.01 or 0.05). But there was no significant difference in the values between LT and VATS. We concluded that (1) elderly patients suffered respiratory muscle weakness before and after operation and their postoperative recovery of respiratory muscle strength was slower than in younger patients, and (2) VATS and LT resulted in more rapid recovery of respiratory muscle strength than PLT, but the difference between VATS and LT was not significant.
