Surgical repair of complete atrioventricular septal defect in 86 patients / 中国医师杂志

ABSTRACT

Objective To investigate the early surgical outcomes of 86 patients with complete atrioventricular septal defect.Methods Between January 2007 and December 2014,consecutive 86 cases received surgical repair in our department.There were 44 male patients,and 42 female patients.Two-patch repair was performed in 69 cases,and modified single-patch repair in 17 cases.The mean age,height,and weight at the time of operation were (32.3 ± 46.5)months with a range from 1 month to 17 years,(82.1 ±27.6) cm with a range from 53 to 165 cm,and (10.8 ± 8.7) kg with a range from 4.1 to 43 kg,respectively.Rastelli A type was found in 67 cases,B type in 15 cases,and C type in 4 cases.Down's syndrome was complicated in 6 cases.Preoperative mild regurgitation of common atrioventricular valve was shown in 32 cases,moderate regurgitation in 38 cases,and moderate to severe regurgitation in 16 cases.Mild pulmonary hypertension was observed in 15 cases,moderate in 54 cases,and severe in 17 cases.Results After operation,all patients were sent into intensive care units (ICU).The mean duration mechanical ventilation,ICU stay,and hospitalization were (30.9 ± 47.7) h with a range from 2.5 to 244 h,(87.7 ± 76.8) h with a range from 14 to 306 h,and (16.4 ±9.2)d with a a range from 6 to 50 d,respectively.We encountered 4 operatively mortalities (4.7％),including 3 in two-patch repair group,and 1 in modified single-patch repair group.The cause of death was mitral regurgitation.Conclusions Modified single-patch and two-patch technique have a satisfied early outcomes.
