[Experience with repeated operations in the late periods after aortic prosthesis for coarctation]

Six repeated operations were performed in periods of one and a half to thirteen and a half years after aortic prosthetics in five patients and shunting in the region of the coarctation in one patient. Severe deformity of the prostheses was revealed during the operation in all cases. Total normalization of the correlation between arterial pressure on the upper and lower extremities was achieved in five persons as a result of the operation. The causes of deformities of the prostheses, the peculiarities of the technique of repeated operative interventions, the methods for correcting circulatory disorders and the indications for reoperations are discussed.
