FIELD: medicine.
SUBSTANCE: to correct circulation for infants with a single functional ventricle, surgical correction is performed in two stages. The first stage includes application of "end to side" anastomosis between the superior vena cava and the right pulmonary artery (RPA), tying of the pulmonary artery trunk. The second stage, not earlier than within a year, intervention is performed, ensuring the establishment of blood flow from the inferior vena cava (IVC) to the pulmonary arteries. For this purpose, an IVC is taken from an adult corpse from the level of common iliac veins merge to the heart confluence area , devitalized, sterilized and stored by freezing. At the second stage of correction anastomoses are created between one end of the stored allovein and child's IVC; between the other end of the stored allovein and the pulmonary arteries bifurcation area with the transition to the child's RPA. At that, separated and thinned allovein walls at its ends are excised prior to anastomosis application. Wall defects at branches transected at the time of twithdrawal are sutured, and transplant ends are modeled in accordance with the child vessel diameters that are anastomosed with the allovein and the distance between them. After transplantation, the allovein is positioned between the right atrium and the pericardium.
EFFECT: method ensures availability, simplicity and prevention of thromboembolic complications and complications due to bleeding disorders of vascular anastomoses suture lines.
