Abstract： Objective?To summarize the clinical experience，surgical technique and indication of coronary artery implantation with double flap extension technique in arterial switch operations （ASO） in D-transposition of the great arteries （D-TGA） and Taussig-Bing anomalies.?Methods?From January 2006 to June 2011， 21 patients （13 males and 8 females；age 110.0±84.5 d；weight 5.4±4.2 kg） with D-TGA or Taussig-Bing anomalies associated with complex coronary artery malformations underwent ASO with double flap extension technique for coronary artery implantation in Shanghai Children’s Medical Center affiliated to Medical College of Shanghai Jiaotong University. All the patients had a main trunk of right coronary artery or dilated right ventricular conus branch originated from the left or right aortic sinus，with abnormal course of anterior looping to the aorta. The double flap extension technique was described as followed： a long coronary button was excised as a flap from the aorta; another pedicle flap on the pulmonary artery （neoaorta） was cut to extend to the button of coronary artery with an equal distance; the side edges of the flap and the button were sutured together to form a lengthened coronary artery tube.?Results?No operative death occurred in hospital. The postoperative duration of mechanical ventilation was 101.6±53.6 h. The duration of ICU stay was 9.5±4.9 d. Postoperatively，low cardiac output syndrome occurred in 9 cases，pulmonary hypertension crisis in 2 cases，pneumonia in 6 cases，and acute kidney failure in 2 cases. Eleven patients underwent delayed sternum closure. All the patients were discharged after proper treatment. Follow-up was complete in 17 cases. The duration of follow-up was 2 months to 5 years. Growth and development were significantly improved in all the patients during follow-up. No patient had ischemic ECG changes. One patient underwent reoperation for supravalvular pulmonary stenosis 2 years after ASO.?Conclusion?Double flap extension technique for coronary implantation in complicated ASO can significantly decrease postoperative death due to coronary artery malformations，especially for patients who have two-stage ASO and patients whose main trunk of right coronary artery or dilated right ventricular conus branch originates from the left or right aortic sinus with abnormal course of anterior looping to the aorta.
ObjectiveTo probe into the risk factors for postoperative surgical site infections in the Department of Cardiothoracic Surgery, and put forward correspondent preventive and treatment measures. MethodA total of 360 patients who underwent operations between February 2011 and March 2013 were the study subjects. The age, sex, basic diseases, surgical time, hospitalization time, surgical implants, and incision category were recorded carefully, and were analyzed for their correlation with surgical site infections. ResultsThere were 27 cases of surgical site infections with an infection rate of 7.50%. Age, hospitalization time, surgical time, basic diseases, surgical implants and incision category were risk factors for surgical site infections (P<0.05). ConclusionsBased on the analysis of risk factors for surgical site infections, we can help patients recover as early as possible by taking preventive measures beforehand.
ObjectiveTo systematically evaluate the effectiveness, safety and ethics of Da Vinci Surigcal System (dVSS)in the field of cardiothoracic surgery, and provide evidence for its clinical application. MethodsWe searched VIP, CNKI, WanFang Database, CBM, official website of National Health and Family Planning Commission of People's Republic of China, PubMed, Cochrane Library, Google Scholar, WHO ICTRP search portal, ClinicalTrials.gov, Chinese Clinical Trial Registration Center, Australian-New Zealand Clinical Trials Registry and ISRCTN to collect clinical trials of dVSS for thoracic and cardiovascular diseases to evaluate its effectiveness, safety and ethics. The search time was from the establishment of each database to January 2014. The quality of included literatures was evaluated by Grades of Recommendations Assessment, Development and Evaluation (GRADE). ResultsA total of 31 studies were identified including 4 case control studies and 27 retrospective studies involving 1 037 patients. The quality of included literatures was all very low. dVSS had been widely used in cardiothoracic surgery including coronary artery bypass grafting, valvuloplasty or valve replacement, thoracic tumor resection, etc. Compared with conventional surgery and thoracoscopy, the safety and effectiveness of dVSS was good, while its economic burden was heavier for the patients. dVSS could benefit patients and improve clinical level of cardiothoracic surgery. The disciplines and qualification of dVSS application was legal, but the maturity of its clinical use needed improvement, and relevant measures were required. The ethics in the research, introduction and application of dVSS had some problems which deserved more attention. ConclusionsClinical use of dVSS in cardiothoracic surgery is relatively safe and effective, but research quality needs to be improved. More studies on the economics and ethics of dVSS are needed in the field of cardiothoracic surgery. Relevant measures of precaution, accountability and patient protection are required to further improve clinical application of dVSS in cardiothoracic surgery, and whole-process ethical supervision should be conducted with the help of existing clinical ethical review platform.
