[Aneurysms of the thoracic aorta detected in patients with aortic coarctation before surgery and in the late period afterwards]. / Anevrizmy grudnogo otdela aorty, vyiavlennye u bol'nykh s koarktatsiei aorty pered operatsiei i v otdalennye sroki posle ee.

At the period from 1964 to 1989 operations were performed on 454 patients with coarctation of the aorta. Long-term results were analyzed in 300 patients operated upon. The cause of the formation of false aneurysms in the area of an anastomosis at later terms after operation was in most cases the partial prosthetic detachment due to cutting or resorption of sutures, inflammatory destruction in the area of anastomosis. All the patients subjected to operation for aorta coarctation, alloprosthesing in particular, need the dynamic follow-up and examination.

[Diastolic changes in isolated stenosis of the pulmonary artery after correction of valvular defect]. / Izmeneniia diastoly pri izolirovannom stenoze legochnoi arterii posle korrektsii poroka.

Intracardiac hemodynamics and myocardial function were studied in 20 patients surgically treated for a valve defect. All the patients developed isolated stenosis of the pulmonary artery. It is emphasized that an early postoperative period in relevant correction proceeds with diastolic impairments. Some factors affecting the degree of the diastolic filling of the right ventricle upon the defect correction are determined. Adequate therapy of the disorders in proposed.

[Treatment of varicose veins]. / Lechenie varikoznoi bolezni.

The authors analyze the results of treatment of 1500 patients suffering from varicose conditions. They have developed original methods for the treatment of varicose dilatation of subcutaneous veins: endovascular and ++perivascular electrocoagulation of subcutaneous veins, removal and crossing of subcutaneous and communicant ++ veins with vein extractor and capron fish line; liquidation of venous conglomerates by means of a submerged removable suture; ++supra-fascial crossing of subcutaneous veins. Employment of these methods in combination with the traditional treatment modalities yields a good therapeutic and cosmetic effect. The methods are simple and available, this recommending them for any surgical hospital.

[The anti-infection resistance system and the pathogenesis of bacterial endocarditis in patients with congenital heart defects]. / Sistema antiinfektsionnoi rezistentnosti i patogenez bakterial'nykh éndokarditov u bol'nykh s vrozhdennymi porokami serdtsa.

The clinico-immuno-microbiological study of 24 patients with congenital heart diseases was made. Clinically, the patients were subdivided into two groups: 8 patients with diagnosed bacterial endocarditis (BE) prior to the operation and 16 patients without BE. The analysis of the results of investigation carried out prior to the operation showed that age, the form of the disease and its duration did not affect the level of anti-infectious resistance factors (AIRF): in both groups a decrease in the level of AIRF characteristics (cell-mediated and humoral) was noted and no characteristic differences were determined. The results of the study of microflora from the nasal and laryngeal mucosa showed no difference in both groups of the patients. At the same time the detailed analysis of the results made it possible to suggest that BE caused by Streptococcus epidermidis and Streptococcus aureus inhabiting the mucous membrane of the anterior sections of the nasal cavity, alpha-hemolytic streptococci and S. epidermidis inhibiting the laryngeal mucosa. The results of the analysis made 3-6 months after the operation were also indicative of the absence of essential differences between AIRF characteristics observed in patients with confirmed and clinically unconfirmed BE. The clinical manifestation of this fact was an increase in the percentage of diagnosed BE cases up to 70% as compared with that before the operation (33%). This clinico-immuno-microbiological study made it possible to come to the conclusion that any form of congenital heart disease develops in combination with BE and/or is its prodrome.

[Endomyocardial biopsy in complicated congenital heart defects]. / Endomiokardial'naia biopsiia pri oslozhnennykh vrozhdennykh porokakh serdtsa.

Endomyocardial biopsy followed by myocardium examination helps detect the changes characteristic of bacterial endocarditis at different stages. This allows rational treatment conducive to a favorable course of the postoperative period.

Developmental defects of the aortic arch and the right subclavian artery.

The study included 10 patients with anomalous development of the aortic arch, of whom 5 had a double aortic arch, 5 had anomalous branching of the right subclavian artery with the formation of a vascular ring. 5 patients were operated with good long-term results during a 15-year follow-up period.
