  • 部分型房室间隔缺损二尖瓣处理策略

    目的 总结部分型房室间隔缺损(PAVSD)患者外科手术的近远期疗效,探讨二尖瓣处理方法。 方法 回顾性分析1990年1月至2008年12月于第二军医大学长海医院行外科治疗PAVSD患者118例的临床和随访资料,男 51例,女67例;年龄7个月~62岁(28.5±12.6岁)。均有原发孔型房间隔缺损和不同程度的二尖瓣前瓣裂隙,其中二尖瓣中重度反流78例,三尖瓣中重度反流56例。手术均在中度低温体外循环下进行。术后通过门诊和电话随访。 结果 术后早期死亡2例,病死率1.69%。发生其他严重并发症为再次气管内插管5例,左心辅助1例,Ⅲ°房室传导阻滞1例。术后随访103例,随访时间3个月~18年(91.2±25.6个月)。再次手术8例,距第一次手术时间为5 d~18年(10.5±5.6年)。再次手术死亡1例。随访生存的102例患者生活质量均有明显改善。二尖瓣无反流70例,微量和轻度反流17例,中度4例。行二尖瓣置换术患者瓣膜功能良好,无抗凝相关并发症。心房颤动19例,Ⅰ°房室传导阻滞21例,频发性房性早搏4例。 结论 二尖瓣修复是PAVSD矫治手术成功的关键,应综合应用二尖瓣成形修复的方法,尽量消除二尖瓣反流;术后二尖瓣再反流是再次手术的主要原因,对中重度二尖瓣反流患者应定期随访和及时手术。

  • Longterm Results of Tetralogy of Fallot in Adults

    Abstract: Objective To evaluate the longterm results of surgical treatment of tetralogy of Fallot (TOF) in adults and discuss the perioperative treatment skills. Methods From January 2000 to March 2008, 149 patients older than 14 years with tetralogy of Fallot received surgical treatment in Changhai Hospital. Among the patients, there were 78 males and 71 females with ages ranged from 14 years to 53 years and the average age was 26.3 years. Twenty patients had previous pulmonary arterial shunts before radical treatment. A total of 129 patients underwent primary radical treatment. Thirtyeight patients received a right ventricular outflow tract patch, 107 patients had transannular patch, and 4 patients had homograft aorta with valves. Results Hospital mortality was 4.0%(6/149). Four patients died of low cardiac output syndrome (LCOS), and multiple organ failure, and 2 patients died of acute renal failure. The postoperative complications included pleural effusion in 11 patients, pulmonary edema in 10 patients, severe LCOS in 9 patients, severe cardiac arrhythmia in 7 patients, reoperation for excessive bleeding in 7 patients, reintubation in 6 patients, and residual ventricular septal defect (VSD) in 5 patients (two of them had reoperation for residual VSD repair and 2 received transcatheter closure of VSD). One hundred and thirtyfour patients were followed up for 3 to 102 months (47.2±28.6 months) with a followup rate of 93.7%(134/143). Late death occurred in 2 patients, one of whom died of secondary infective endocarditis and the other had a sudden death 29 months after operation. During the followup, one patient had residual VSD (2 mm), but had a normal life. The peak systolic right ventricletopulmonary artery pressure gradient exceeded 40 mmHg in 4 patients. Two patients had severe pulmonary regurgitation. A total of 132 patients survived and had an improved life. One hundred and twentyone patients had class Ⅰ heart function (NYHA), and 11 patients in class Ⅱ. Conclusion The pathophysiologic conditions of the patients with tetralogy of Fallot in adults are very complicated due to longterm right ventricle outlet stricture and chronic hypoxia. Preoperative evaluations and postoperative treatment of complications are necessary. The systemicpulmonary arterial shunts should be performed when hypotrophy of the pulmonary arteries or left ventricles exists. Repair of tetralogy of Fallot in adults has acceptable morbidity and mortality rates with goodlongterm outcomes.

  • Surgery Treatment of Chronic Moderate Ischemic Mitral Regurgitation in Coronary Artery Disease

    Objective To investigate the treatment and prognosis of moderate ischemic mitral regurgitation (IMR) in coronary artery disease(CAD). Methods From January 1998 to May 2006, 28 patients of CAD with moderate IMR underwent coronary artery bypass grafting (CABG) and mitral valve plasty(MVP, 24) or mitral valve replacement (MVR,4). The Reed method were used in 9 cases, the annuloplasty ring were used in 15 cases. Mechanical valve were implanted in 1 case and biological valve in 3 cases. Results There was no operative or hospital death. Twentysix patients were followed up to a mean period of 41 months. There were two late death(one was MVP, the other was MVR). In MVP cases, nineteen patients were in New York Heart Association (NYHA) functional class Ⅰ and Ⅱ, 3 in class Ⅲ, which was better than that of preoperative one. Ultrasonic cardiography (UCG) examination showed no mitral regurgitation in 5 cases, mild in 7, light in 6, moderate in 3, severe in 1. Left atrial volume (LAV) and left ventricular enddiastolic volume (LVEDV) were 54.1±12.7ml and 60.9±14.8 ml, decreased more significantly than that preoperatively (Plt;0.05). In MVR cases, 2 cases were survival and followed. One patient was in NYHA functional class Ⅰ, 1 in class Ⅱ, which was better than that of preoperative one. Conclusion Moderate IMR with CAD should be treated carefully. MVP with annuloplasty ring have better early results. For patients with bad heart function and abnormal left ventricular wall motion, the late results need more studies.

  • Clinical analysis of 31 lung metastases patients by percutaneous thermal ablation in a single center

    ObjectiveTo explore the factors that affect the accuracy of percutaneous thermal ablation of lung metastases and coping strategies.MethodsWe retrospectively analyzed the clinical data of 31 patients who met the conditions for thermal ablation of lung metastases in Ninth People’s Hospital affiliated to Shanghai Jiao Tong University School of Medicine between October 2019 and December 2020. There were 19 males and 12 females with a mean age of 40-81 (62.8±10.3) years. A total of 33 metastases tumors were thermally ablated, 12 were radiofrequency ablation and 19 were microwave ablation.ResultsOf the 33 metastatic tumors, 5 targets showed significant puncture deviation, 4 of them completed the ablation after adjustment and 1 failed. The result of the univariate logistic regression showed the distance within the lung parenchyma (P=0.043) and the maximum diameter of the tumor (P=0.025) were independent risk factors for the accuracy of percutaneous thermal ablation. In terms of correlation, there was a positive correlation between the accuracy of percutaneous thermal ablation and the distance within the lung parenchyma (P=0.033), and a negative correlation between the maximum diameter of metastases tumor (P=0.004) and hemoptysis (P=0.015). Complete ablation rate was 87.8% (29/33).ConclusionWhen we perform CT-guided percutaneous thermal ablation of lung metastases, we must fully prepare the deviation plan for the small diameter tumor, the long travel distance in the lung parenchyma, and hemoptysis during puncture. Complete ablation can be achieved by fully identifying the anatomical features of the tumor and its surrounding structures, shortening the travel distance in the lung parenchyma and increasing the ablation range.

  • Cardiac Surgery Via Minimally Invasive Incision versus Median Sternotomy: A Systematic Review

    Objective To evaluate whether minimally invasive (MI) cardiac surgery has advantages over conventional median sternotomy (MS), so as to provide evidence for clinical diagnosis and therapy. Methods We searched CBM, VIP, CNKI, PubMed, and Elsevier databases from 1995 through 2008. The literature about the therapeutic effect of minimally invasive cardiac surgery and conventional median sternotomy was identified. The data was extracted, and the methodological quality was evaluated by two reviewers independently. The Meta-analyses were performed using RevMan 4.2 software. Results A total of 8 studies involving 492 MI patients and 712 MS patients met the inclusion criteria. Of these eight studies, two studies were randomized trials and the other six studies were retrospective cohort studies. The results of meta-analyses showed that the MI group had a better postoperative effect, and the cardiopulmonary bypass time (WMD=16.45, 95%CI 2.56 to 30.35, P=0.02), chest-tube drainage (WMD= –132.63, 95%CI –208.53 to –56.72, P=0.0006) and hospitalization stay (WMD= –1.22, 95%CI –2.14 to –0.30, P=0.009) of MI group were less than those of MS group, but the aorta clamping time (WMD=0.47, 95%CI –1.35 to 2.29, P=0.61) and operating time (WMD=26.67, 95%CI –8.91 to 62.25, P=0.14) were not significantly different between the two groups. Conclusion The minimally invasive cardiac surgery has a better postoperative therapeutic effect than conventional median sternotomy cardiac surgery.
