Objective To summarize the experiences of surgical treatment of sinus venosus atrial septal defect （SVASD）. Methods There were 32 patients of SVASD, all of them were associated with totally or partially right anomalous pulmonary venous connection. There were 25 cases of superior SVASD, 22 cases underwent double-patch procedure, 3 cases underwent Warden procedure. In 7 cases of inferier SVASD, 3 cases of Scimitar syndrome underwent ASD repair by pericardial patch and at the same time the anomalous pulmonary vein was divided and reimplanted to the posterior wall of left atrium, 4 cases of them underwent single-patch ASD repair. Results The surgical results were satisfying and no patient died, 28 patients were in sinus rhythm and echocardiography showed neither obstruction of caval vein and right pulmonary vein nor residual interatrial shunt. Conclusion SVASD mostly associated with right anomalous pulmonary venous connection according to its special anatomic structure. Preserving the function of sinus node and avoiding of obstruction of caval vein should be routinely considered when superior SVASD was repaired. The heart function of Scimitar syndrome should be followed-up for a long time for it usually associated with right lung hypoplasia.
ObjectiveTo explore the early results of Ozaki operation in children with aortic regurgitation.MethodsWe retrospectively analyzed the clinical data of 15 patients with aortic regurgitation who received the Ozaki operation in our hospital from April 2017 to July 2019. There were 11 males and 4 females with an average operation age of 10.7±3.7 years. Besides preoperative evaluation, aortic regurgitation and cardiac function were evaluated on 1 day, 1 week, 1 month, 3 months, and 6-12 months after surgery.ResultsIn 14 (93.3%) patients , the aortic valve leaflets functioned well on 1 day, 1 month, 3 months, and 6-12 months, and the regurgitation grade was Ⅰ-Ⅱ, which was improved than before (P=0.001). The cardiac function of children recovered quickly after operation. There was no statistical difference in ejection fraction on 1 day, 1 month, 3 months, and 6-12 months after operation (P>0.05). No children died, and no other clinical event was found.ConclusionThe Ozaki technique of reconstructing a tricuspid aortic valve leaflet for the treatment of severe aortic regurgitation in children is effective in short term, and the persistence of its valve function remains to be determined in the long-term follow-up.
Objective To explore the surgical management method and outcome of functional univentricular heart with total anomalous pulmonary vein drainage (UVH-TAPVD). Methods We reviewed the surgical procedures and results for 44 UVH-TAPVD patients in our hospital between the year 2010 and 2016. There were 34 males and 10 females. The age of the patients was 312 (77-4 220) d when they accepted the first surgical treatment. Results There were 8 deaths in stage Ⅰ palliation, 1 death in stage Ⅱ palliation and 5 deaths during the follow-up. The overall survival rate was 68.2% (30/44). Glenn operation was undertaken in 34 patients with 5 deaths. Fontan operation was undertaken in 9 patients with 2 deaths. Conclusion Surgical strategies for UVH-TAPVD should be planned according to different anatomical and pathophysiological conditions in different patients. Staged palliations can reduce mortality and morbidity. But pulmonary venous obstruction and heterotaxy syndrome are still risk factors for these patients.
Objective To analyze the performance of epidemic prevention of Sichuan Province in the reconstruction stage after Wenchuan earthquake, so as to provide references for future epidemic prevention when such emergencies occur. Methods Data about the relief work were collected from the archives of Centers of Disease Control and Prevention in earthquake-stricken areas. And then the data were classified and analyzed. Results In the reconstruction stage, epidemic prevention followed principals of local-based, local-management, assistance-relied and joint -forces-pushed. The strategies included strengthening the capacity of CDCs through personnel training and improving abilities of hygiene service. Owing to these strategies, the epidemic prevention in Sichuan Province was conducted vigorously, orderly and effectively. Conclusion The epidemic prevention strategies in the reconstruction stage in Sichuan Province are accurate and effective, which could be recommended when such emergencies occur in future.
