    Abstract:
    The effect of the Blalock-Taussig operation on the growth of the pulmonary arteries (PA) in infants with tetralogy of Fallot (TF) was studied in late-term periods. Thirty-eight patients were examined, angiography and study of hemodynamics were conducted 31 to 144 months after the Blalock-Taussig operation. The obtained data provide evidence that as the result of the operation all segments of the hypoplastic PA grew to such a size that radical correction of the anomaly could be accomplished. In patients with an initially normal size of the PA growth of the vessel was not encountered. Iatrogenic complications and deformities of the PA occurred in 13.2% of cases. These complications developed most frequently (7.9%) in patients in whom the anastomosis was established in the first year of life. The degree of severity of the infundibular stenosis grew in all patients. Severe obstruction of outflow from the right ventricle developed in 10.5% of patients; in 7.9% of children it was completely obstructed. In view of that prolonged delay of the second stage of surgical treatment is inexpedient.
