ObjectiveTo discuss the operative techniques and results of coarctation resection plus aortoplasty with pulmonary autograft patch for coarctation of the aorta combined with hypoplastic aortic arch in infant.MethodsBetween May 2007 and Dec 2009，14 cases including 9 males and 5 females with coarctation of the aorta and hypoplastic aortic arch underwent coarctation resection plus aortoplasty with pulmonary autograft patch in our hospital.The age ranged from 23 days to 17 months，with a median of 4.33 months.The mean body weight was(6.14 ±2.36)kg.All patients were diagnosed as aortic coarctation combined with VSD and hypoplastic aortic arch.The surgery was performed under deep hypothermia cardiopulmonary bypass with selective cerebral perfusion in 8 cases and circulation arrest in 6 cases.Fresh pulmonary autograft patch harvested from the main pulmonary artery was used for aortoplasty.The associated VSD was repaired in the same stage.ResultsAll patients survived except one died from circulatory failure during the perioperative period.Low cardiac output syndrome occurred in another case who was cured afterwards by correspondent treatments.No residual obstruction was detected by echocardiography after the operation.Follow-up was carried out in 13 cases from 4 months to 3 years.Echocardiographic examination showed that the pressure gradient across the aortic arch was less than 16 mmHg in all cases.The blood velocity at the descending aortic arch was not significantly changed during the follow-up period as compared with that immediately after operation.Computed tomography showed that the morphology of aortic arch was normal.The left bronchus compression was relieved obviously or totally disappeared in patients who suffered from left bronchus stenosis before operation，and no aortic aneurysm were detected in these patients.ConclusionCoarctation resection plus aortoplasty with pulmonary autograft patch is the optimal surgical method for treating coarctation of the aorta combined with hypoplastic aortic arch in infant.14 refs，2 figs.
