[Formation of pseudoaneurysms at the site of prosthetic surgery of the aorta using a synthetic prosthesis in coarctation]

Abstract

Two patients who underwent 28 and 20 years ago operation for correction of coarctation of the aorta and its restoration by synthetic dacron prostheses were examined. They had characteristic complaints. Examination by functional and invasive methods revealed changes in the synthetic prostheses which caused the characteristic complaints and elements of the disease. The findings of autopsy were studied in a case of sudden death 25 years after repair of the aorta by a dacron prosthesis in coarctation. Morphological examination revealed essential changes in the synthetic dacron prosthesis which led to complications in the late postoperative period.
