[Results of surgical treatment of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries].

This article presents the 14-year experience of surgical treatment of pulmonary atresia with ventricular septal defect and pulmonary collateral blood bed. The surgery of defect was performed on 32 patients and they were followed up. The individual and differential approaches should be used in the choice of surgical strategy.

[Results of bidirectional cavapulmonary shunt operation without cardiopulmonary bypass in children with complicated congenital heart defects during the first year of life].

The authors present results of bidirectional cavapulmonary shunt operation without cardiopulmonary bypass for the treatment of complicated congenital heart defects. Temporary blood shunting during surgical intervention enables cavapulmonary anastomosis to be created without making resort to artificial circulation (AC) and limitation on the time of superior vena cava occlusion. The proposed method is free from additional risks and excludes negative effects of AC.

Eight years clinical experience with the replacement of the ascending aorta using composite xenopericardial conduit.

Objective: The evaluation of early and late results after ascending aorta replacement with composite glutaraldehyde-treated xenopericardial valved conduit.

Methods: From December 1989 to May 1999 the ascending aorta was replaced with 148 composite xenopericardial conduits aorta in 145 patients. Biological valves were inserted in 28 conduits, mechanical valves - in 116.

[Intraoperative finding of complicated congenital heart defects in dogs].

Vitium cordis found in a dog comprised a defect of the interatrial septum, pulmonary artery trunk aneurysm and right pulmonary artery atresia. The heart chambers were filled with polymer protacryl mass for obtaining the cast. No such anomalies have been described in the literature so far.

[Unsolved problems of the surgical treatment of dissecting aneurysms of the ascending aorta (analysis of complications)].

It is shown that various complications occurring after surgical treatment of dissecting aneurysms of the ascending aorta with or without aortic insufficiency depend mainly on the methods of correction applied and the etiology of the disease. As the result of the study the authors conclude that the Bentall-De Bono and Cabroe's operations are radical methods for surgical management of dissecting aneurysms of the ascending aorta irrespective of the etiology of the disease. Wide introduction of these operative methods into the clinical practice led to an essential decrease of hospital mortality and the frequency of complications in the immediate and late-term postoperative period.

[Long-term results of the surgical treatment of aneurysm of the ascending aorta in combination with aortic valve insufficiency].

Four of 28 patients who were operated on died in late-term periods, four from advancing cardiac failure and one died 5 years after an operation from cardiac tamponade. In the group of four patients one underwent Cabrol's operation, three were operated on by the Bentall-De Bono method. The condition of 25 patients considerably improved and they were related to the II and I functional classes.

Surgical treatment of dissecting aneurysm of the ascending aorta: immediate and late results.

The authors describe experience gained with surgical treatment of dissecting aneurysm of the ascending aorta in the period from 1978 to 1987. 30 patients were operated on using the techniques proposed by Bentall, De Bono and Carbrol. All patients exhibited the presence of annulo-aortic ectasia.

[Surgical tactics in dissecting aneurysms of the ascending aorta].

The aspects of surgical tactics in management of dissecting aneurysms of the ascending aorta are analysed in relation to the disease etiology, the anatomical pattern of the aortic root, presence of attending aortic insufficiency, and dissection extension. Based on the experience of 32 operations (March 1979--February 1988), it is concluded that the abnormal type must be the best criterion for choosing the surgical technique. In dissecting aneurysms due to aortic wall degeneration, Bentall-De Bono and Cabrol's modifications are preferable.

[Surgical treatment of aneurysm of the ascending aorta in Marfan syndrome].

An experience with 26 operations for aneurysms of the ascending aorta with a concomitant insufficiency of the aorta valve in Marfan syndrome is described. We started using operations after Bentall-De Bono in 1979 and operations after Cabrol in 1983 which were used in cases with low localization of openings of the coronary arteries in relation to the fibrous ring of the aorta valve, as well as in cases with the dissecting aorta wall, especially involving the area of the openings. These operations allowed the intrahospital lethality to be reduced: in the period of 1979-86 it made up 30% (6 patients died out of 20), in 1983-86 it was 15.

[Immediate results of the surgical treatment of aneurysms of the ascending aorta associated with aortic insufficiency].

Experience with surgical treatment of ascending-artery aneurysms with concomitant aortic insufficiency is summed up. Forty-four patients were operated on, 30 of those having dissecting aneurysm of the ascending aorta. There were 6 operations where coronary arterial openings were isolated and stitched into a valve-containing conduit and 8 supracoronary resections with prosthetic aortic valve implantation.
