[Reoperation for coarctation of the aorta and interrupted aortic arch].
This report presented four patients who underwent surgery for restenosis after repair of coarctation of the aorta (CoA) or interrupted aortic arch (IAA) at our institution between January 1980 and October 1994. Case #1 underwent primary repair for IAA, VSD, and PDA consisting of aortic arch reconstruction using a EPTFE (expanded polytetrafluoroethylene) graft of 10 mm in diameter at the age of four years. After 17 years, pressure gradient of 58 mmHg between the ascending aorta and the descending aorta prompted the reoperation. Case #2 underwent primary repair for CoA, VSD, and PDA consisting of a bypass between the ascending aorta and the descending aorta with an EPTFE graft of 11 mm in diameter at the age of three years. After 13 years, he had reoperation because of pressure gradient of 64 mmHg. Case #3 had pressure gradient of 20 mmHg between the upper and lower limb at the hospital discharge following patch angioplasty for CoA at five years of age. He underwent unsuccessful percutaneous transluminal balloon angioplasty at age 12 and had reoperation at age 15. Case #4 underwent subclavian flap angioplasty as the first stage operation for CoA, VSD, and PDA at 1 month after birth. About 9 months after the initial operation, the pressure gradient between the upper and lower limb had reached 40 to 50 mmHg, and the patient had reoperation at the age of 1 year. The reoperation method for cases #1, #2 and #3 consisted of bypass grafting from the left subclavian artery to the descending aorta under a simple cross clamping of the thoracic aorta.(ABSTRACT TRUNCATED AT 250 WORDS)
