Yasui procedure for surgical repair of interruption of aortic arch and ventricular septal defect associated with aortic stenosis or aortic atresia / 中华胸心血管外科杂志

ABSTRACT

Objective:To study the surgical results of Yasui procedure for interruption of aortic arch and ventricular septal defect(IAA/VSD) associated with aortic stenosis(AS) or aortic atresia(AA).Methods:A retrospective study was performed on all 4 children with IAA/VSD/AS(AA) that underwent a Yasui procedure from Dec 2014 to Dec 2019. Three patients had AS, and 1 patient had AA. The age was from 10 days to 25 months and the weight was from 2.7 kg to 10 kg. The type of IAA was type A in 1 and type B in 3. The diameter and Z value of the aortic annulus were 1.9-4.3 mm and -6.7--3.6. The diameter and Z value of the ascending aorta were 2.6-5.8 mm and -5.4--2.6. The mean Z value of LVEDD and LVEDS was 3.6±2.6 and 3.6±2.9 resparately.Results:All 4 patients survived after the Yasui procedure. Three patients underwent primary repair and 1 patient underwent staged repair. CPB time was 128-283 min and aortic cross-clamping time was 98-171 min. Ventilation time was 93-296 h, and ICU and hospital length of stay was 7-25 days and 18-39 days. Follow-up was complete in all patients from 8 to 92 months, and there was no late death. All the patients were in good biventricular function with NYHA grade Ⅰ in 3 and NYHA grade Ⅱ in 2 patients. No residual left ventricular outflow tract obstruction was detected.Conclusion:The Yasui procedure can be an option for patients with IAA/VSD/AS(AA) and good developed left ventricle and can achieve good early surgical results.
