Outcomes were compared with children who underwent repair of truncus arteriosus without aortic arch obstruction ( n = 163) during the same period. We sought to review the long-term outcomes of patients with truncus arteriosus with an interrupted aortic arch at the Royal Children’s Hospital. However, many centres have reported truncus arteriosus with an interrupted aortic arch to be a risk factor for death. There is limited cumulative experience regarding the management of this condition, the long-term outcomes. The combination of truncus arteriosus and an interrupted aortic arch is rare. Truncus arteriosus, Interrupted aortic arch, Surgery INTRODUCTION At last follow-up, no clinically significant aortic arch obstruction was identified in any patient, and all patients were in New York Heart Association Class I/II. Follow-up was 95% complete (19/20), with a median follow-up time of 20 years. Freedom from aortic arch reoperation was 69 ± 11% (95% CI 42–85) at 10 and 20 years. Six patients underwent 10 aortic reoperations. There were no late deaths and overall survival was 83 ± 8% at 20 years. The early mortality rate was 17% (4 out of 24 patients). A period of deep hypothermic circulatory arrest was used in 16 patients, and isolated cerebral perfusion was used in 8 patients. One patient, the first in the series, underwent interrupted aortic arch repair via subclavian flap aortoplasty prior to truncus repair.
#INTERRUPTED AORTIC ARCH SURGERY PATCH#
Direct end-to-side anastomosis of the ascending and descending aorta was performed in 16 patients (67%, 16/24), patch augmentation in 5 patients (21%, 5/24) and direct anastomosis with the use of an interposition graft to the descending aorta in 2 patients (8%, 2/24). The median age at repair was 10 days and the median weight was 3.1 kg.
