title: [Attempt at allo-aortal conduits in the correction of congenital heart defects].
abstract: In the period September 1990 to April 1993, an allo-aortic conduit was used in 16 patients during reconstruction of the right ventricular outflow duct. The patients age ranged from 2 years 8 months to 14 years, their body weight was 11.8 to 26 kg. Seven patients were diagnosed as having pulmonary atresia with ventricular septal defect, 4 had Fallot's tetrad and 5 transposition of great vessels with pulmonary stenosis and ventricular septal defect. The allo-aortic conduit made by the procedure developed at the A. N. Bakulev Institute of Cardiovascular Surgery, Russian Academy of Medical Sciences, was used in all cases to reconstruct the right ventricular outflow duct. The allografts were sterilized in a solution containing culture medium RPMI-1640 and mixture of antibiotics. After sterilization, the prostheses were frozen in liquid nitrogen vapours and kept at -150 to -160 degrees C till their clinical application. In the immediate postoperative period, 2 patients died, which amounted to 13%. Two deaths were caused by excessive bleeding, but in one case the implanted conduit wall bled. The residual right ventricle-pulmonary artery gradient was no more than 23 +/- 17 mm Hg. A discharge echocardiographic examination of patients found no valvular dysfunction of the implanted conduits on days 12 to 26 days after surgery. The findings suggest that the allo-aortic conduits prepared at the A. N. Bakulev Institute of Cardiovascular Surgery, Russian Academy of Medical Sciences, can be regarded as the prostheses of choice in the surgery of congenital cardiac malformations.
