ABSTRACT
Objective The aim was to evaluate the development of pulmonary arteries(PA) in patients with pulmonary atresia,ventricular septal defect and diminutive pulmonary arteries by using a central end-to-side shunt between the ascending aorta and pulmonary arteries and to identify the associated factors for the results.Methods 51 consecutive patients(37 male,14 female) with pulmonary atresia,ventricular septal defect and diminutive pulmonary arteries received a central end-to-side shunt between PA and the ascending aorta from May 2004 to June 2013.Ages and weight ranged between 2-86 months and 2.5-21.5 kg,respectively.39 patients with main PA diameters less than 4 mm received the central end-to-side shunt between the ascending aorta and PA,and 14 patients with main pulmonary arteries absence received a modified shunt.Results There were no deaths during operation and follow-up.Compared with preoperative measures,total pulmonary artery index increased from a mean value of(68.8 ± 11.4) mm2/m2 to(129.1 ± 24.9) mm2/m2 (P < 0.001) at the time of six months or the final repair after shunt.The increased pulmonary artery index change was(87.7 ± 27.4) % (27.0% to 150.0%).By multivariate regression analysis,age at shunt,shunt procedure and number of major aortopulmonary collateral arteries were correlated with increasing pulmonary artery index change.Conclusion The central end-to-side shunt between the ascending aorta and pulmonary arteries promoted sufficient growth of the diminutive central pulmonary arteries.Due to the risk of a distortion of pulmonary branches,we interposed a modified procedure for patients with main pulmonary arteries absence.It is technically easy to perform,warrants low risk of shunt thrombosis in the early postoperative period.
