Objective To summarize our clinical experience of bidirectional Glenn procedure (BGP) for the treatment of complex cyanotic congenital heart disease (CHD). Methods Clinical data of 68 patients with complex cyanotic CHD who underwent BGP in People's General Hospital of Xinjiang Uygur Autonomous Region from January 2007 to December 2012 were retrospectively analyzed. There were 40 male and 28 female patients with their average age of 3.9 years (range, 3 months to 22 years) and body weight of 6.2-53.0 (13.6±8.5)kg. Preoperative diagnosis included tricuspid atresia in 20 patients, single ventricle (SV) in 11 patients, double outlet right ventricle in 10 patients, complete transposition of great arteries in 7 patients, tricuspid stenosis in 5 patients, pulmonary atresia in 5 patients, corrected transposition of great arteries in 4 patients, tetralogy of Fallot in 4 patients and Ebstein's anomaly in 2 patients. Among them, there were 14 patients with dextrocardia or dextroversion of the heart, 2 patients with SV and pulmonary hypertension after pulmonary artery banding, and 1 complete transposition of great arteries patient after aortopulmonary shunt. Twenty-three patients received BGP under cardiopulmonary bypass (CPB) and 45 patients received BGP without CPB. Results Two patients died postoperatively, including 1 patient with severe low cardiac output syndrome (LCOS) and another patient with pulmonary infection. Postoperative pulse oximetry oxyhemoglobin saturation (SpO2, 89.3%±7.4%) was significantly higher than preoperative SpO2 (66.8%±11.8%, P < 0.05). In 53 patients, postoperative SpO2 was more than 10% higher than preopera-tive SpO2. Postoperative hematocrit (0.40±0.07) was significantly lower than preoperative hematocrit (0.49±0.11, P < 0.05). Postoperative complications included pleural effusion in 16 patients (23.5%), chylothorax in 7 patients (10.3%), LCOS in 5 patients (7.4%), arrhythmias in 4 patients (5.9%), and pneumothorax in 1 patient (1.5%), who were all cured after appropriate treatment. Fifty-five patients were followed up for 9 months to 6 years after discharge with satisfactory clinical results. All anastomoses remained patent without stenosis or thrombosis. Four patients successfully received total cavopulmonary connection 2 to 5 years after discharge. Conclusion BGP is safe and reliable for patients with complex cyanotic CHD who cannot undergo anatomic correlation or one-stage repair.
