Examined were 42 patients with aortal coarctation at the age of from 6 to 35 years. The differences in hemodynamics, microcirculation and oxygen regimen of tissues depending on the degree of aortal coarctation were revealed. To diagnose the degree of aortostenosis, it is suggested to use the transcutaneous monitoring of PO2 distally to the site of coarctation.

The results of perinatal management and surgical treatment of 30 newborn babies, owing antenatally diagnosed isolated aortal coarctation (AC) and 40 newborn babies, in whom this diagnosis was not established antenatally, were analyzed. Application of antenatal diagnosis and optimization of the patients' perinatal management algorithm have permitted to reduce the treatment duration in the intensive therapy division of cardiosurgical department. In newborn babies, to whom the diagnosis of AC was established antenatally, a trustworthy reduced duration of postoperative pulmonary artificial ventilation was revealed in comparison with such in patients, in whom this diagnosis was not established antenatally.
