ObjectiveTo analyze the outcomes of complicated congenital heart diseases (CCHD) patients accepting multiple (>2) re-sternotomy operations.MethodsWe retrospectively analyzed the clinical data of 146 patients undergoing multiple cardiac re-sternotomy operations between 2015 and 2019 in our center. There were 95 males and 51 females with an age of 4.3 (3.1-6.8) years and a weight of 15.3 (13.4-19.0) kg at last operation.ResultsThe top three cardiac malformations were pulmonary atresia (n=51, 34.9%), double outflow of right ventricle (n=36, 24.7%) and functional single ventricle (n=36, 24.7%). A total of 457 sternotomy procedures were performed, with 129 (88.3%) patients undergoing three times of operations and 17 (11.7%) patients undergoing more than three times. Fifty-two (35.6%) patients received bi-ventricular repair, 63 (43.1%) patients received Fontan-type procedures, and 31 (21.2%) patients underwent palliative procedures. Ten (6.8%) patients experienced major accidents during sternotomy, including 7 (4.8%) patients of urgent femoral artery and venous bypass. Eleven (7.5%) patients died with 10 (6.8%) deaths before discharge. The follow-up time was 20.0 (5.8-40.1) months, and 1 patient died during the follow-up. The number of operations was an independent risk factor for the death after operation.ConclusionSeries operations of Fontan in functional single ventricle, repeated stenosis of pulmonary artery or conduit of right ventricular outflow tract post bi-ventricular repair are the major causes for the reoperation. Multiple operations are a huge challenge for CCHD treatment, which should be avoided.

Abstract： Objective To summarize our operative experiences of cardiac reoperation after mechanical valve prosthesis replacement and investigate the causes of reoperation and the perioperative techniques and operation methods. Methods From January 2001 to December 2008, we performed reoperation on 105 patients (59 males and 46 females, aged 50.2±10.6 years old) who had undergone mechanical valve prosthesis replacement. Among the patients, there were 31 cases of mitral valvular replacement (+ tricuspid valvular plasticity), 38 cases of aortic valvular replacement (+ tricuspid valvular plasticity), 11 cases of Bentall procedure, 7 cases of mitral and aortic bivalvular replacement (+tricuspid valvular plasticity), 8 cases of tricuspid valvular replacement, 6 cases of repairing of prosthetic leakage, and 4 others cases. The time interval between two operations was 3 months to 18 years (46.3 ±31.9 months). Before reoperation, the cardiac function (NYHA) of the patients was class Ⅱ in 27 patients, class Ⅲ in 53 patients, and class Ⅳ in 25 patients. Results There were 6 hospital deaths with a mortality of 5.71%(6/105). All others recovered to NYHA class ⅠⅡ. The causes of mortality included 1 case of multiple organ failure, 1 case of low cardiac output after operation, 1 case of aortic pseudoaneurysm rupture, 1 case of severe infection due to brain complication and 2 cases of prosthetic valve endocarditis (PVE). The causes for cardiac reoperation after mechanical valve prosthesis replacement were 67 cases of prosthetic leakage (63.80%), 16 cases of PVE (15.23%), 14 cases of prosthetic thrombosis (13.33%) and 8 cases of other valvular anomalies. Followup was done for 11 to 107 months, which showed two cases late deaths of cardiac arrest and cerebral hemorrhage. Conclusion Patients who have received mechanical valve prosthesis replacement may undergo cardiac reoperation due to paravalvular prosthetic leakage, paravalvular endocarditis, and prosthetic thrombosis. The keys to a successful cardiac reoperation include appropriate preoperative preparations, operational timing, and suitable choosing of cardiopulmonary bypass and operational skills.
ObjectiveTo investigate and evaluate the safety and efficacy of Bentall operation in the reoperation of patients with small aortic root or annulus.MethodsBentall procedure was performed in 24 patients with small aortic root or annulus in our hospital from September 2014 to December 2019. There were 18 males and 6 females with a mean age of 31-68 (45.70±15.27) years. All patients had undergone a previous replacement of the aortic valve including 20 patients receiving valve replacement, 2 patients aortic root replacement with a valved conduit and 2 patients bioprothesis replacement.ResultsThere was no early death in hospital and one death during the 30-day postoperative period. Re-thoracotomy due to bleeding was necessary in only 2 patients and no bleeding was related to the proximal anastomosis of the conduit. One patient performed pacemaker implantation for heart block after the procedure. The mean sizes of implanted aortic valve prosthesis were 22.75±1.78 mm. A mean gradient across the aortic valve prostheses in the postoperative echocardiographic examination was 11.17±2.24 mm Hg.ConclusionBentall procedure is safe and allows a larger size of prosthesis implantation in patients with small aortic annulus or root after previous aortic valve or complete root replacement, resulting in good postoperative hemodynamic characteristics and short-term clinical results.
Objective To summary the operative technique of liver retransplantation （RLT）. Methods The clinical data of 62 cases who had received RLT in our institute from Jan. 2003 to Jun. 2012 were analyzed retrospectively， and the experience about RLT was summaried too. Results The operative time 〔（12.7±3.5） h vs. （10.5±3.0） h〕， bleeding volume （3 431 mL vs. 2 211 mL）， and blood volume transfused during operation （3 229 mL vs. 1 910 mL） in 62 cases who had underwent RLT were longer or higher than that of 38 patients who had underwent the first liver transplantation （LT） in our hospital （P＜0.05）， but there was no significant difference on the model for end-stage liver disease （MELD） score between the 2 groups （P＞0.05）. All cases were followed up for 1-104 months （average 31 months）. Twenty case died within 1 month after RLT， including sever lung or abdominal infection in 13 cases， multiple organ failure in 4 cases， hepatic artery complication in 2 cases， and portal vein complication in 1 case. Eight cases died of tumor recu-rrence during 14-69 months （average 27 months） after RLT. The cumulative survival rate of 1-， 2-， and 5-year of 62 cases of RLT were 67.7%， 59.7%， and 56.4%， respectively. The 34 patients had survived for 3-104 months （average 49 months）， of them， there were biliary stenosis in 3 cases who were cured by interventional radiology treatment， biliary stenosis in 2 cases who were cured by a third RLT， infection in 10 cases who were cured by anti-infective therapy and immunosuppressant adjustment， light rejection in 2 cases who were relieved by dosage increase of oral immunosuppressant， other 17 cases suffered no complications and all in good condition. Conclusions RLT is an effective method for irreversible graft failure after LT. Proper surgical procedure contributes to the increase of survival rate of patients who has received RLT.
目的探讨腹腔镜胆道再次手术的适应证、手术方法及临床效果。方法回顾性分析我院2003年2月至2010年11月期间46例腹腔镜胆道再次手术患者的临床资料，对术中及术后结果进行总结。结果本组45例在腹腔镜下完成手术，1例中转开腹。手术时间为45～270 min(平均120 min)，残株胆囊切除时间为(40±10) min，胆总管切开取石+T管引流时间为(150±50) min，胆总管切开取石+等离子碎石+T管引流时间为(180±40) min，术后出血及漏胆腹腔镜探查术时间为（40±15）min。结石一次性取尽23例，术后残余结石2例，住院4～21 d，平均8.6 d。胆管残余结石患者在术后1个月后经T管瘘道用胆道镜取石。术中十二指肠球部损伤3例，及时发现修补; 术后出现右侧胸腔积液4例、肺部感染2例和漏胆1例，均经非手术治疗痊愈。术后电话随访6～24个月（平均15个月），未见异常。结论腹腔镜胆道再次手术可行，并具有创伤小、恢复快等优点，但术前应严格掌握手术适应证，对手术医生的技术要求也较高。
