ObjectiveTo summarize our clinical experience of bidirectional Glenn procedure (BGP) for the treatment of complex cyanotic congenital heart disease (CHD). MethodsClinical 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. ResultsTwo 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. ConclusionBGP is safe and reliable for patients with complex cyanotic CHD who cannot undergo anatomic correlation or one-stage repair.
Objective To summarize the experience of the superior vena cava and pulmonary connection surgery for functional single ventricle (SV) with total anomalous pulmonary venous (TAPVC). Methods We retrospectively analyzed the clinical data of 10 patients with SV and TAPVC in our hospital from January 2012 through June 2014. There were 7 males and 3 females at average age of 90.33±86.53 months. The 10 patients were with right atrial isomerism, 9 with heterotary and asplenia syndrome. Five patients were anatomic single ventricle and others were with functional uni-ventricle. Nine patients were with supracardiac pattern TAPVC and one was with intracardiac TAPVC. All patients were operated unilateral or bilateral bidirectional Glenn procedure with TAPVC correction. Results The arterial oxygen saturation (SaO2) increased prominently after operation (86%±6% vs. 79%±6%, P<0.01). There were 3 patients with low cardiac output syndrome, one patient with severe arrhythmia, 4 patients with serious pleural effusion, 4 patients with hospital-acquired infection, and 3 patients with central nervous system complications (epilepsy or hemiplegia). One died because of hemorrhage and pulmonary thrombosis, and the other died of hypoxemia and mutiple organ dysfunction syndrome (MODS). Conclusion Glenn is one of palliated procedure choice for SV/TAPVC patients. The indication for surgery and perioperative management individually is crucial.
Objective To analyze the feasibility of bidirectional Glenn procedure (BDG) in treatment of adult congenital heart disease (ACHD). Methods From December 2004 to December 2015, 42 ACHD patients received BDG in our hospital. There were 23 males and 19 females with a mean age of 24.6±8.5 years (range: 18 to 49 years). There were functional single ventricle (FSV) in 14 patients, Ebstein’s anomaly in 11, corrected transposition of great arteries in 7, transposition of great arteries in 5, double outlet of right ventricle in 3 and tricuspid atresia in 2. Twenty patients suffered moderate or severe atrioventricular valve regurgitation (AVVR). Half of the patients were operated upon with cardiopulmonary bypass (CPB) and the others with off-pump coronary artery bypass grafting (OPCABG). Thirty-four patients underwent unilateral BDG shunt and eight bilateral BDG shunts. Concomitant procedures included correction of Ebstein’s anomaly (7 patients), atrioventricular valve replacement (7), atrial septostomy (3), ligation of patent ductus arteriosus (3), ligation of major aortopulmonary collateral arteries (2), correction of total anomalous pulmonary venous connection (1) and mitral valve repair (1). Results The early operative mortality was 9.5% (4/42). FSV and moderate or severe AVVR were risk factors for BDG in ACHD. Early postoperative oxygen saturation increased from 78.8%±11.2% to 89.3%±6.6% (P<0.05). The follow-up time was 6-132 (41.4±33.1) months. There was no death. The heart function improved (2.7±0.5 vs. 1.9±0.4, P<0.05). Conclusion The BDG shunt can be applied to ACHD. Although the early mortality is relatively high, the middle- and long-term results are satisfactory. The oxygen saturation increases and the heart function improves. The life quality of patients will also improve. FSV and moderate or severe AVVR are risk factors for BDG in ACHD.
