Objective To explore current results after staged operations in patients with functional single ventricle anomalies and pulmonary hypertension. Methods We retrospectively analyzed the clinical data of 129 patients with functional single ventricle anomalies and pulmonary hypertension undergoing pulmonary artery banding in our hospital between April 2008 and December 2015. There were 81 males and 48 females. There were 71 patients with double outlet of right ventricle, 17 patients with tricuspid atresia, 7 patients with transposition of great arteries, 33 patients with uni-ventricular heart, and one patient with complete atrio-ventricular septal defect. The surgical results, transition to Glenn procedure and subsequent transition to Fontan procedure were analyzed. Results The 129 patients underwent 159 operations of pulmonary artery banding totally. Hospital mortality was 4.7% (6/129). Nine patients were lost to follow-up. Eighty-seven (67.4%) patients underwent the second-stage Glenn procedure, and 43 patients(33.3%) underwent third-stage Fontan procedure. Two patients died after Glenn and 3 patients died after Fontan separately. There were 32 patients who accompanied with coarctation, interruption of aortic arch, heterotaxy, total anomalous pulmonary venous connection or atrio-ventricular valve regurgitation. Fifteen (46.9%) patients succeeded in transition to Glenn, and 6 (18.8%) patients succeeded in transition to Fontan. Fourteen patients developed obstruction of left ventricular outlet tract or bulbo-ventricular foramen. Conclusion Early pulmonary artery banding is an acceptable strategy for patients with single ventricle anomalies and pulmonary hypertension. Outcomes and results of subsequent Glenn and Fontan procedures are generally good. Accompanied complex anomalies are risk factors for lower ratio of transition to Glenn and Fontan procedure.
Objective To assess the mid- and long-term outcomes of right ventricular outflow tract reconstruction for children with congenital heart disease. Methods We retrospectively analyzed the clinical data of 3 138 children with complex congenital heart disease in right heart system admitted to our hospital from January 2007 to January 2017. There were 1 660 males and 1 478 females. The age at surgery was 9 days to 84 months, and the body weight was 2.2 to 28.6 kg. Pulmonary patch enlargement was performed in 2 335 patients (1 477 patients of valve-sparing repair and 858 patients of transannular repair); autologous tissue (direct anastomosis, left auricle or pericardial conduit) was used to connect with right ventricle in 289 patients; extracardiac conduits were used for reconstruction in 514 patients. Results There were 181 in-hospital deaths with a mortality of 5.8%. The early postoperative causes of death were low cardiac output syndrome (LCOS), severe pulmonary hypertension and right heart failure. Fifteen patients died of cardiac insufficiency or sudden death during follow-up (6–27 months postoperatively). The echocardiography showed 408 patients with right ventricular outflow tract obsturction (RVOTO), 340 patients with pulmonary trunk or branches stenosis, 609 with pulmonary regurgitation (morderate or severe). 12.6% (394/3 138) of patients underwent reintervention or reoperation with 39 deaths. About 92.4% of patients exhibited an improvement of New York Heart Association (NYHA) functional class from Ⅲ or Ⅳ preoperatively to Ⅰ or Ⅱ at follow-up. Conclusion The anatomical structure of right ventricular outflow tract is complicated and various, and each operation method has different strengths and favorable outcomes. The operation should be individually designed according to pathological types, anatomical features, clinical symptoms and operation conditions.
ObjectiveTo summarize and explore the individualized surgical treatment strategy and prognosis of anomalous aortic origin of coronary artery (AAOCA). MethodsThe clinical data of children with AAOCA admitted to Shanghai Children's Medical Center from March 2018 to August 2021 were retrospectively analyzed. ResultsA total of 17 children were enrolled, including 13 males and 4 females, with a median age of 88 (44, 138) months and a median weight of 25 (18, 29) kg. All patients received operations. The methods of coronary artery management included coronary artery decapitation in 9 patients, coronary artery transplantation in 5 patients and coronary artery perforation in 3 patients. One patient with severe cardiac insufficiency (left ventricular ejection fraction 15%) received mechanical circulatory assistance after the operation for 12 days. No death occurred in the early postoperative period, the average ICU stay time was 4.3±3.0 d, and the total hospital stay was 14.4±6.1 d. All the children received regular anticoagulation therapy for 3 months after discharge. The median follow-up time was 15 (13, 24) months. All patients received regular anticoagulation therapy for 3 months after discharge. No clinical symptoms such as chest pain and syncope occurred again. The cardiac function grade was significantly improved compared with that before operation. Imaging examination showed that the coronary artery blood flow on the operation side was unobstructed, and no restenosis occurred. ConclusionAAOCA is easy to induce myocardial ischemia and even sudden cardiac death. Once diagnosed, operation should be carried out as soon as possible. According to the anatomic characteristics of coronary artery, the early effect of individualized surgery is satisfactory, and the symptoms of the children are significantly improved and the cardiac function recovers well in the mid-term follow-up.
ObjectiveTo analyze the clinical efficacy of right midaxillary straight incision surgery in the treatment of doubly committed subarterial ventricular septal defect. MethodsThe clinical data of children with doubly committed subarterial ventricular septal defect who received surgeries in our hospital from August 2020 to July 2023 were analyzed retrospectively. All the children underwent surgical repair and were divided into two groups according to the incision position, including a right midaxillary straight incision group and a median incision group. The outcomes were compared between the two groups. ResultsA total of 187 patients were enrolled. There were 102 patients in the right midaxillary straight incision group, including 55 males and 47 females with a median age of 26.0 (5.0, 127.0) months and a median weight of 12.5 (5.1, 32.8) kg at surgery. There were 85 patients in the median incision group, including 37 males and 48 females with a median age of 4.0 (2.0, 168.0) months and a median weight of 6.7 (4.8, 53.9) kg at surgery. No mortality occurred in the study. There was no statistical difference between the two groups in the cardiopulmonary bypass time (50.0±18.4 min vs. 46.1±15.7 min) or aortic cross-clamping time (31.3±18.6 min vs. 26.3±17.5 min) (P>0.05). Compared to the median incision group, the time from the end of cardiopulmonary bypass to the closure of chest (22.3±15.6 min vs. 37.1±13.4 min, P=0.001), postoperative hospital stay (6.9±3.9 d vs. 8.6±3.6 d, P=0.002), the length of incision (4.3±2.7 cm vs. 8.5±3.2 cm, P=0.001), drainage volume (79.0±32.2 mL vs. 100.2±43.1 mL, P=0.001), and the pain score on the 2nd and the 3rd day after the operation were statistically better in the right midaxillary straight incision group (P<0.05). The medical experience and incision satisfaction scores at discharge were higher than those in the median incision group (P<0.05). During the follow-up of 21.0 (1.0, 35.0) months, no residual shunt was detected and all patients in both groups had a normal cardiac function and mild or less valve regurgitation. ConclusionCompared to the median incision, minimally invasive right midaxillary straight incision is equally safe and reliable in the treatment of doubly committed subarterial ventricular septal defect with the advantages of cosmetic and fast recovery.
ObjectiveTo evaluate the safety, efficacy, and cost-effectiveness of different uses of oxidized regenerated cellulose (ORC) in video-assisted thoracoscopic surgery (VATS) for lung cancer resection to provide a reference for the selection, clinical use, and rational utilization of absorbable hemostatic materials. MethodsA retrospective analysis of relevant data from inpatients who underwent VATS for lung cancer resection at a tertiary hospital from July 2019 to January 2020 and from July 2020 to December 2020 was conducted. Patients were divided into two groups based on the use of ORC: 1) combined use group (ORC and collagen sponge) and 2) sole-use group (ORC). Safety, efficacy, and economic outcome indicators were compared between the two groups. ResultsThe main analysis included a total of 904 patients, with 466 in the combined use group and 438 in the sole-use group. Compared to the combined use group, the sole-use group had a significantly longer hospital stay, used fewer hemostatic drugs, had a lower average cost of hemostatic materials, and a lower median total hospitalization cost (P<0.05). No statistically significant difference was found between the two groups in terms of intraoperative blood loss volume, massive blood loss rate, perioperative transfusion rate, reoperation rate, postoperative 48-hour drainage volume, bloody drainage fluid rate, or postoperative laboratory test indicators. ConclusionThere was no significant difference in the safety or efficacy of VATS for lung cancer resection between the sole use of ORC and the combined use of ORC, but the sole use of ORC was associated with a lower cost of hemostatic materials and a lower total hospitalization cost. The sole use of hemostatic gauze in VATS for lung cancer resection may be a more cost-effective choice.
ObjectiveTo analyze the risk factors and re-intervention strategies for mid- and long-term residual after arterial switch operation (ASO). MethodsThe clinical data of children with complex congenital heart disease who underwent ASO surgery in Shanghai Children’s Medical Center from January 2006 to June 2022 were retrospectively collected, and the factors for mid- and long-term residual after ASO were analyzed. ResultsA total of 952 children undergoing ASO were enrolled in this study, including 654 males and 298 females with an average age of 102.9±90.1 d and weight of 4.6±1.6 kg. There were 421 patients with D-transposition of the great arteries with intact ventricular septum (D-TGA/IVS), 357 patients with D-transposition of the great arteries with ventricular septal defect (D-TGA/VSD), and 174 patients with right ventricle double outlet combined with inferior pulmonary artery absence (Taussig-Bing malformation). Eighty-nine patients died early after the surgery, the mortality rate was 9.3%. The 746 surviving children were regularly followed up after the surgery (follow-up rate 86.4%), with a median follow-up time of 79.4 (12.0-188.0) months. During the follow-up, 53 children underwent surgical re-intervention due to residual, including 33 males and 20 females, with a median age of 62.5 (17.0-214.0) months. The median surgical weight was 19.0 (8.2-86.0) kg, and the mean time of re-intervention was 28.0-170.0 (77.5±45.4) months after the ASO. Residual problems included common trunk and branch stenosis of the pulmonary artery in 34 patients, right outflow tract stenosis in 11 patients, left outflow tract stenosis in 6 patients, aortic arch restenosis in 5 patients, aortic insufficiency in 5 patients, residual shunt of ventricular septal defect in 2 patients, and tricuspid valve insufficiency in 1 patient. Two patients died early after the re-intervention because of acute left heart failure, and the mortality rate was 3.8% (2/53). The mean follow-up time of the surviving children was 52.4±28.6 months, and no mid- and long-term death occurred. Two patients underwent the third operations due to pulmonary restenosis. The multivariate analysis result showed that combined aortic arch surgery and early postoperative right ventricular outlet tract (RVOT) velocity>3 m/s were independent risk factors for mid- and long-term residual after ASO. ConclusionASO is an ideal surgical method for the treatment of D-TGA/IVS, D-TGA/VSD and Taussig-Bing malformations. Combined aortic arch surgery and early postoperative RVOT velocity>3 m/s are independent risk factors for mid- and long-term residual after ASO.
