Abstract
Pulmonary atresia with defect of interventricular septum and collateral pulmonary blood flow refers to complicated congenital malformation of the heart. Surgical treatment represents itself as very difficult task because of anatomical variability of this abnormality. The main problem of surgery is a definitive repair of the defect including correction of maldistributions of pulmonary arterial bed (unifocalization of pulmonary blood flow), reconstruction of outflow tract of the right ventricle and closing of interventricular septum defect. The performance of closing interventricular septum defect could be successful in patients with pulmonary atresia and collateral pulmonary blood flow in case of stepwise and one-step surgical treatment. The combination of maximal number of pulmonary segments and sufficient development of central pulmonary arteries facilitates to progress of assigned task. Patients with the level of pulmonary-arterial index more than 170 mm/m² and integrity of pulmonary arterial bed, centralization of pulmonary segments (minimum 15) could be considered as a candidate for definite repair of the defect.
