ABSTRACT
ObjectiveTo evaluate the clinical application of bidirectional Glenn shunt without extracorporeal circulation(ECC) on treatment of children with complicated congenital heart disease (CHD).MethodsForty-six patients with complicated CHD(without ECC group) underwent bidirectional Glenn shunt without ECC,and 40 patients with complicated CHD (with ECC group) underwent bidirectional Glenn shunt with ECC.The therapeutic effect was compared between two groups.ResultsThere was no operative mortality in two groups.The pulmonary artery pressure in without ECC group was significantly lower than that in with ECC group [( 16.7 ± 1.2) mm Hg ( 1 mm Hg =0.133 kPa) vs.( 18.9 ± 1.0) mm Hg,t =4.686,P=0.026 ].Duration of respirator assistance after operation in without ECC group was significantly lower than that in with ECC group [ ( 12.2 ± 2.7) h vs.( 19.2 ± 2.8) h,t =2.972,P =0.041 ].There was no significant difference in saturation of blood oxygen and the rate of chylothorax after operation between two groups (P＞0.05).The symptoms and signs including cyanosis and breath were markedly alleviative in all patients.ConclusionBidirectional Glenn shunt without ECC is an effective and safe method for complicated CHD.
