[Late postoperative complications of coarctation of aorta]

Main complications of the remote 2-35 years period after coarctation of the aorta repair are studied up. Of 2746 patients 2464 (89.7%) were operated upon at the age of 2-25 years old. In 841 (30.61%) of patients were determined coexistent heart diseases, more often aortic valve lesion. End-to-end anastomosis was fulfilled in 44.6% of operations and patch repair was done in 43.6%. The most frequent complication of the remote period was the aortic aneurysm-in 61 (2.2%) of cases. It occurred seven times more frequently after the patch repair (4.1%) then after anastomosis end-to-end conduction (0.6%). Late postoperative mortality equaled 1.5%. The main reasons of it were aneurysms at the site of repair--in 12 patients, aneurysms of the ascending aorta--in 4 and progressing of the coexisting heart diseases--in 10.
