目的总结左胸骨旁小切口微创封堵分流方向偏向流出道的室间隔缺损（VSD）的初步经验。 方法2014年2～8月广州医科大学附属第一医院对15例分流方向偏向流出道的VSD患者施行左胸骨旁小切口微创封堵手术，其中男7例，女8例；年龄10个月～19岁（4.5±4.6）岁；体重5.5～54.0（14.6±14.1）kg；其中干下型6例，嵴内型6例，膜周部型3例；缺损直径2.5～6.5（4.0±1.2）mm，距主动脉瓣环距离≤1 mm 9例，≤2 mm4例，>2 mm 2例；合并主动脉瓣右冠瓣轻度脱垂5例；采用左胸骨旁第2或第3肋间1.5～2.5 cm切口，在经食管超声心动图（TEE）监视下在右心室流出道表面选择适当的穿刺点，建立VSD输送轨道并置入封堵器，观察有无残余分流、主动脉瓣反流；术后3个月复查经胸超声心动图。 结果15例均成功封堵，无中转开胸，无残余分流和心律失常，新发主动脉瓣轻微反流2例，围手术期输血1例；手术时间30～120（58±28）min，术中出血量5～200（26±50）ml；术后住院时间3～13（4.3±2.6）d，无二次开胸止血、Ⅲ°房室传导阻滞、主动脉瓣反流加重、溶血、切口感染等并发症；术后3个月返院复查经胸超声心动图13例，无新发主动脉瓣反流和封堵器脱落；2例术中新发主动脉瓣反流加重，其中1例出现残余分流。 结论左胸骨旁小切口封堵分流方向偏向流出道VSD 手术安全、切口小、操作简单，近期效果尚满意；对合并主动脉瓣轻度脱垂VSD 需慎重施行外科微创封堵手术。
Objective To explore the advantage of transection the cervical muscles at sternal end and flip fixed in therapeutic bilateral huge thyroid surgery. Methods The transection of the cervical muscles at sternal end and flip fixed in 53 cases was observation group， 44 cases of the neck white line incision thyroid surgery completed for the control group. The completion of the surgery by the same group of physicians. The operative time， operation field of exposing effect， amount of bleeding in operation， postoperative complications， and postoperative drainage volume were compared between two groups. Results There was no statistically differences of sex， age， disease composition， and tumor size between two groups （P＞0.05）. Operative time， amount of bleeding， and postoperative drainage volume in observation group were shorter （less） than that in control group （P＜0.01）. The postoperative complication rate in observation group was lower than that in control group（P=0.04）. Surgical field exposure in observation group was better than that in control group （P＜0.01）. Conclusions The huge bilateral thyroid surgery with the sternal end approach is feasible and simple. The operation field exposure is better than the white line neck incision， complications after operation is less. It is worthy of clinical application.
Objective To investigate surgical strategies using bilateral pectoralis major muscle flaps for the treatment of sternal dehiscence after cardiac surgery. Methods From May 2005 to October 2010，21 patients with sternal dehiscence, sternal osteomyelitis and mediastinitis after cardiac surgery were admitted to Beijing An Zhen Hospital of Capital Medical University. There were 13 male patients and 8 female patients with their age of 53-72 （64.5±7.8） years. There were 19 patients after coronary artery bypass grafting （CABG） and 2 patients after heart valve replacement. The non-viable and necrotic bones were debrided and sternal wires partially or completely removed. The sternal origins of pectoralis major were released on both sides. The pectoralis major muscle flaps were tensionlessly sutured across medially over the sternal defect. Multiple suction drains were placed and removed in due time. The skin was intermittently closed. Results All the pectoralis major muscle flaps lived well after surgery，and all the patients were discharged in 2 weeks after surgery. Twenty patients were discharged with complete wound closure，and 1 patient had wound fistula and infection after removal of suction drains that was healed after another surgery to resect the wound fistula. During 6 month follow-up，sternal wound healed well in all the patients with normal thoracic appearance，and none of the patients had abnormal respiratory movement, infection recurrence or persistent infection. Conclusion Bilateral pectoralis major muscle flap technique is a positive and efficient surgical strategy for the treatment of refractory sternal dehiscence after cardiac surgery.
Abstract： Objective To explore the application of lower sternal incision with on-pump， beating heart intracardiac procedures in mitral valve replacement （MVR）. Methods We retrospectively analyzed clinical data of 42 patients （minimal incision group） with valvular heart diseases who underwent MVR via lower sternal incision under the beating heart condition in Xinqiao Hospital of the Third Military Medical University from January 2011 to December 2011. There were 16 male and 26 female patients with their average age of 42.3±12.7 years in the minimal incision group. We also randomly selected 42 patients with valvular heart diseases who underwent MVR via routine midline sternotomy during the same period in our department as the control group. There were 18 male and 24 female patients with their average age of 43.8±13.1 years in the control group. Operation time， cardiopulmonary bypass time， major complications， chest drainage in postoperative 24 hours， skin incision length and average postoperative hospital stay were observed and compared between the two groups. Results There was no major perioperative complication such as in-hospital death. There was no reexploration for postoperative bleeding， complete atrioventricular block， embolism or perivalvular leakage in the minimal incision group. There was no statistical difference in cardiopulmonary bypass time， operation time， or the incidence of reexploration for postoperative bleeding， wound infection and perivalvular leakage between the two groups（P＞0.05）. The skin incision length in the minimal incision group was shortened by 5.2 cm compared to that in the control group （7.9±1.4 cm vs. 13.1±3.3 cm， P=0.000）. Chest drainage in postoperative 24 hours in the minimal incision group was significantly less than that of the control group （183.6±40.2 ml vs. 273.4±59.9 ml， P=0.000）. Postoperative hospital stay in the minimal incision group was significantly shorter than that of the control group （8.1±1.3 d vs. 10.6±2.1 d， P=0.000）. Forty patients in the minimal incision group were followed up for 3-15 months and 2 patients were lost during follow-up. Four patients had postoperative wound pain， and the majority of patients didn’t have significant wound scar formation but a satisfactory quality of life. Thirty-eight patients in the control group were followed up for 3-15 months， 4 patients were lost during follow-up， and 17 patients had postoperative wound pain. Conclusion Lower sternal incision with beating heart can reduce the surgical injury， simplify the operation procedure and improve the therapeutic efficacy. It is a safe， effective and esthetic surgical approach for MVR.
Objective To investigate surgical indications，techniques，safety and clinical outcomes of minimallyinvasive sternal lowering operation for the treatment of pectus carinatum （PC）. Methods Clinical data of 40 PC patientswho underwent minimal invasive sternal lowering operation in Xinhua Hospital，School of Medicine，Shanghai Jiao Tong University from July 2009 to August 2012 were retrospectively analyzed. There were 39 male patients and 1 female patientwith their average age of 14.5 （12-22）years. All the patients underwent their surgical correction for the first time，and their chest deformity were characterized by a significant protrusion of the sternum and ribs including 21 symmetric and 19 asymmetric protrusions. Preoperative evaluation included electrocardiogram，CT scan of the chest，echocardiogram and pulmonary function test. Preoperative mean Haller index was 1.91±0.23. Sixteen patients had mild restrictive ventilatory disorder. Allthe patients received minimally invasive sternal lowering operation with a curved Nuss steel bar. Aggravating activities wererestricted within 3 months postoperatively，and the steel bar was removed 2 years later. Results All the operations were completed successfully，and thoracic appearance was significantly improved after correction. All the patients and their relativeswere very satisfied with the corrective outcomes. The operation time was 65-115 （82.0±15.6）minutes and average intraop-erative blood loss was less than 10 ml. Postoperative hospital stay was 3-5 （3.5±0.8） days. Postoperative Haller index was2.39±0.17，which was significantly higher than preoperative Haller index （P＜0.01） . Postoperative complications included wound infection in 2 patients，pneumothorax in 1 patient （cured by closed thoracostomy），subcutaneous effusion in 3 patients，and persistent pain （longer than 14 days） in 2 patients. There was no other serious postoperative complication. All the 40 patients were followed up for 3-36 months after discharge. A steel bars was removed ahead of schedule because of wound infection in one patient. Other steel bars were in normal position in 39 patients and there was no displacement of the steel bars or the stabilizers. Eight patients received removal of the steel bars without PC recurrence. Conclusion Juveniles with PC who have good chest wall compliance are the best candidates for minimally invasive sternal lowering operation which is an easy，safe，reliable，minimally invasive and esthetic procedure with satisfactory corrective outcomes.
