OBJECTIVE: To evaluate the early and mid-term outcome of surgical repair for post-ductal coarctation of the aorta (CoA) under normothermia without cardiopulmonary bypass.
METHODS: Clinical data from 15 patients (11 males, 4 females, mean age 18 +/- 10 years) undergoing surgical repair for post-ductal CoA under normothermia without cardiopulmonary bypass between January 1999 and December 2004 were analyzed retrospectively. There were 7 isolated cases, 7 cases associated with patent ductus arterious (PDA), 1 case with PDA and ventricular septal defects. Operation was performed under normothermia with partial cross-clamping of descending aorta in 8 cases, compete cross-clamping in 6 cases and temporary shunt in 1 case. Operative techniques adopted prosthetic bypass graft in 9 cases, Gore-Tex patch graft aortoplasty in 4 cases and stenosis resection with end-to-end anastomosis in 2 cases. PDA was ligated at single-stage in 8 cases. Ventricular septal defect was repaired at second stage in 1 case.
RESULTS: No early and late death. Hypertension occurred in 9 cases during early postoperative period but was normalized gradually in 5 cases without medication during follow-up period, from 6 months to 5 years. The arterial blood pressure of lower extremities increased significantly and no hoarseness, paraplegia occurred after operation. No recoarctation and aneurysm formation were found during follow-up.
CONCLUSION: Surgical repair of post-ductal CoA under normothermia without cardiopulmonary bypass is safe and effective, which is a procedure of choice for patients with isolated CoA, CoA associated with PDA, or with other intracardiac anomalies that are ready to be repaired at second-stage.
