Objective To summarize clinical outcomes of right ventricle-to-pulmonary artery shunt (Sano shunt)as the first stage palliative operation for patients with pulmonary atresia with ventricular septal defect (PA/VSD). Methods Between September 2009 and May 2011,17 PA/VSD patients underwent Sano shunt in Fu Wai Hospital. There were 10 male patients and 7 female patients with their median age of 9.7 (2.5-73.8) months and average weight of (8.3±3.4)kg. Preoperative McGoon ratio was 1.04±0.29 and Nakata index was (102.0±56.9) mm2/m2. Five children had severe intrapericardial left pulmonary aretery stenosis,11 patients had patent ductus arteriosus (PDA),and 1 patient had major aorto-pulmonary collateral arteries. Preoperative transcutaneous oxygen saturation (SpO2) was 72.6%±11.6%. Results All the patients received Sano shunt placement successfully. Eleven patients underwent concomitant PDA ligation,and 7 patients underwent concomitant left pulmonary artery plasty. The Sano shunts were constructed with glutaraldehyde-fixed autologous pericardium in 10 patients,fresh autologous pericardium in 1 patient and Gore-Tex graft in 6 patients. All the patients underwent reconstruction of the right ventricular outflow tract via the right ventricular incision. The average cardiopulmonary bypass time was (75.0±30.0) min. Postoperative SpO2 was 89.8%±5.3% and significantly higher than preoperative SpO2 (P<0.05). All the patients were discharged alive and followed up for (12.1±6.7) months. During follow-up,8 patients underwent angiography study whose McGoon ratio and Nakata index improved to 2.05±0.37 and (304.8±51.3) mm2/m2 respectively,both of which were significantly higher than preoperative values(P<0.05). Four patients successful underwent second stage total correction. Conclusion Sano shunt is a comparatively safe procedure as the first stage palliative operation for PA/VSD patients,and can significant improve their pulmonary artery growth.
