[Urgent surgical correction of ventricular septal defects in children of first months of life].

The article presents the results of urgent surgical correction of ventricular septal defects (VSDs) and a range of associated congenital heart diseases (CHDs) in 123 children of the first 6 months of life, hospitalized between 1988 and 2002 in a severe or critical condition. In 102 patients the progression of clinical symptoms was caused by a big single VSD and in 21 patients--by multiple VSDs. 70 patients had significant associated CHDs. Significant extracardiac anomalies were revealed in 75 patients. The condition of 55.3% of children had deteriorated due to pneumonia. Correction of defects with cardiopulmonary bypass was performed after urgent examination and intensive therapy. Hemodynamically significant VSD were closed in 117 (95.2%) patients. Two patients were reoperatied due to the presence of residual VSD. Partial or full simultaneous correction of associated CHDs was performed in 68 patients. 93.5% of patients with isolated VSDs survived the operation. The survival rate of patients with associated CHDs and extracardiac anomalies was 81.5%. Postoperative mortality risk factors were found to be critical condition at hospitalization and preoperative activity of infectious process (P < 0.01 and < 0.05, respectively). Accumulation of experience and introduction of a special approach allowed an 8-time decrease of the hospital mortality, which has not exceeded 3.4% within last 3 years. Good and excellent follow-up results were obtained in 98% of the survived patients within 10 to 67 months after operation. Precise diagnostics of associated CHDs and extracardiac anomalies, intensive preoperative treatment and weighed estimation of indications and risk factors allow significant improvement in the results of primary correction of VSD and accompanying cardiovascular anomalies in children of the first months of life in a heavy and critical condition upon admission.

[Significance of intravascular ultrasound studies in the evaluation of the vascular lumen and wall in interventional radiological procedures]. / Znachenie vnutrisosudistogo ul'trazvukovogo issledovaniia v otsenke sostoianiia prosveta i stenki sosudov pri interventsionnykh radiologicheskikh protsedur.

The paper analyzes the first experience with intravascular ultrasound study (IUSS) in 9 patients at the Cardiosurgery Center. It presents the potentialities of IUSS during interventional radiological procedures. It is concluded that there are benefits and trends of the technique in the exploration of various vascular beds.

[Surgical treatment of cryptorchism in children]. / Operativnoe lechenie kriptorkhizma u detei.

A method of sparing fixation of the testicle in cryptorchidism is described. It was used in 200 children. Good and satisfactory long-term results were obtained in all the patients operated upon.

[Surgical treatment of pseudarthroses and defects of the long bones at polyclinics]. / Operativnoe lechenie lozhnykh sustavov i defektov dlinnykh trubchatykh kostei v poliklinike.

The author describes his experience with the operative treatment after G. A. Ilizarov of 22 patients with false joints under conditions of the out-patient clinic. Good results were obtained in all the cases. The method of periosseous osteosynthesis is recommended for wide use under conditions of the the out-patient clinic.

[Variability of sinus rhythm during deep respiration]. / Issledovanie variativnosti sinusovogo ritma serdtsa pri glubokom dykhanii.

A possibility was studied of applying the deep and infrequent respiration test with an object of increasing the informativeness of the statistical parameters of the ECG sequence interval as applicable to the quantitative evaluation of the functional state of man. Examination of patients with wound infection shown that the deep respiration test makes in possible to assess quantitatively the status of test subjects on the basis of two statistical parameters (the mean value of RR interval of ECG and root-mean-square deviation).
