Objective: to determine the rate of diaphragmatic eventration after the congenital heart defects (CHD) reconstruction in children, and to identify risk factors for the relapse of diaphragmatic eventration after its primary operation.
Materials and methods. A retrospective analysis of inpatient medical records at the Republican Scientific and Practical Centre of Paediatric Surgery (RSPCPS) in Minsk (the Republic of Belarus) during the period of 01/08/2018 to 01/01/2017 was conducted. The analysis of primary surgery protocols for the CHD correction, features of the postoperative course and methods of primary plastic surgery in diaphragmatic eventration was carried out. Statistical processing of the data was carried out using the MedCalc Version 17.6.
Results. During the analysed period, 6325 open heart operations were performed at the RSPCPS, and in 120 (1.8%) cases, the eventration of one of the diaphragm cupulas was observed in P/O period as complication. After the initial correction of diaphragmatic eventration, 12 (10%) out of 120 patients experienced a relapse, which required reoperation. The following statistical analysis of the data showed a significant increase in the number of relapses in the group of patients who underwent plastic surgery involving the use of U-shaped sutures on pads. In the group of patients transferred to spontaneous breathing in the first 12 hours after the operation, there were no relapses, while in group 2 (in which the time of breathing using the artificial ventilation was from 12 to 72 hours), the risk of relapse decreased 1.3 times as compared with patients of group 3, who needed respiratory support more than 72 hours. When applying «soft» regimens of the artificial ventilation, approximately a 4-time reduction of relapses was observed.
Conclusions. For the period from August 1, 2006 to January 1, 2017, the diaphragmatic eventration in the patients operated on CHD was diagnosed in 120 (1.8%) cases, which corresponds to literature data. Most likely the reason for the relapse of diaphragmatic eventration is the type and technique of the primary surgical intervention. Features of the postoperative course and artificial ventilation parameters in the patients after the primary plasty of the diaphragm with subsequent relapse of the disease are revealed. The choice of the optimal method of surgical correction of diaphragmatic eventration associated with a complex of postoperative management of patients will allow minimizing the number of relapses.
