Surgical Treatment of Coarctation of Aorta -The Report of Two Cases-

대동맥 축착증 수술치험 2례

Coarctation of the aorta is classically a congenital narrowing of the upper descending thorac aorta adjacent to the site of attachment of the ductus arteriosus which is sufficiently severe that there is a pressure gradient across the area. Recently we have experienced two cases of coarctation of the aorta and successfully performed resection of the sites of coarctation and end to end anastomosis of the aorta. The first case was a juxtaductal type of coarctation of the aorta with PDA and the pathology of the lesion was a diaphragm with central narrow opening. And the resection length was about 0.5cm and aortic clamping time was 20 minutes. The second case was also juxtaductal type coarctation of the aorta with mild tubular hypoplasia of aortic isthmus, left SVC and the pathology was also a diaphragm with central narrow opening. And the resection length was about 0.5cm and aortic clamping time was 29 minutes. Both postoperative course was uneventful and the patients were discharged two weeks after operation.
