Abstracts： Objective To summarize clinical experience and surgical outcomes of congenital coronary arterial fistula （CAF）. Methods We retrospectively analyzed clinical records of 12 patients （6 males, 6 females）, aged from 4 to 77 （50.90±23.8） years, who underwent surgical repair of CAF in Nanjing First Hospital between February 2005 and June 2011. There were 3 CAF patients associated with coronary artery aneurysms, one with patent foramen ovale and 2 with coronary artery disease （CAD）. One CAD patient had concomitant severe aortic valve stenosis. One patient underwent surgical repair without cardiopulmonary bypass （CPB） and 11 patients underwent surgery under CPB, among whom 3 patients underwent surgery with beating heart. One patient underwent concomitant aortic valve replacement and coronary artery bypass grafting.?Results?All the patients recovered uneventfully. Operation time was 151.25±42.65 min （ranging from 90 to 245 min）, cardiopulmonary bypass time was 65.06±29.16 min （ranging from 31 to 116 min）, mean aortic cross-clamping time was 43.00±33.41 min （ranging from 18 to 97 min） and postoperative hospital stay was 12.50±1.45 d （ranging from 10 to 15 d）. There was no early or late death. All the patients were followed up from 4 months to 6 years and no patient had symptom recurrence, myocardial ischemia or residual fistula during the follow-up. Conclusions All CAF patients should be surgically treated once diagnosis are made with satisfactory surgical outcome.
Objective To compare surgical outcomes of Stanford type A acute aortic dissection between operations at midnight and daytime. Methods From January 2004 to March 2013，195 patients with Stanford type A acute aortic dissection received surgical treatment in Nanjing Hospital Affiliated to Nanjing Medical University （Nanjing Cardiovascular Disease Hospital）. Patients with identical or similar propensity scores were matched from 127 patients who underwent emergency operation at daytime and 68 patients who underwent emergency operation at midnight. A total of 58 pairs of matched patients which had the same or similar propensity score were selected in daytime surgery group （n=58，43 males and 15 females，47.7±14.6 years） and midnight surgery group （n=58，45 males and 13 females，48.3±14.6 years）. Operation time，postoperative chest drainage，mechanical ventilation time，postoperative incidence of dialysis and tracheostomy，length of ICU stay and in-hospital mortality were compared between the daytime group and midnight group. Results A total of 58 pair of patients were matched in this study. There was no statistical difference in postoperative incidence of tracheostomy ［19.0% （11/58） vs. 6.9% （4/58），P=0.053］ or in-hospital mortality ［8.6% （5/58） vs. 6.9%（4/58），P=0.729］ between the midnight group and daytime group. Operation time （485.7±93.5 minutes vs. 428.5±123.3 minutes，P=0.048），postoperative chest drainage （979.5±235.7 ml vs. 756.6±185.9 ml，P=0.031），mechanical ventilation time （67.9±13.8 hours vs. 55.7±11.9 hours，P=0.025），postoperative incidence of dialysis ［17.2% （10/58） vs. 5.2%（3/58），P=0.039］ and length of ICU stay （89.4±16.2 hours vs. 74.8±12.5 hours，P=0.023） of the midnight group weresignificantly longer or higher than those of the daytime group. A total of 107 patients were followed up for 4-6 months after discharge. During follow-up，there was no late death. Among the 13 patients who required postoperative dialysis，12 patientsno longer needed regular dialysis. Conclusion Emergency operation at midnight does not increase in-hospital mortalitybut increase some postoperative morbidity in patients with Stanford type A acute aortic dissection. Whether at midnight or daytime，better preoperative preparation and surgeons’ vigor are needed for timely surgical treatment for patients with Stanford type A acute aortic dissection.
Abstract: Objective To investigate the role of video-assisted thoracoscopic surgery (VATS) in treatment of benign pulmonary disease, in order to promo te the mini-invasive way of operation. Methods From May 2001 to M ay 2006, 128 patients with benign pulmonary diseases were treated by VATS. The diseases included 17 kinds of different lesions, such as tuberculosis, bronchiectasis, inflammatory pseudotumor, giant bullae of lung, hamartoma,lymphangiomyomatosis, etc. 53 cases had definite diagnosis before operation, the others had final diagnosis by pathology. Limited resection were performed in 66 cases, single lobectomy in 56 cases, bilobectomy in 2 cases, and concomitant bilateral lobectomy in 4 cases. Limited resections were carried out by pure thoracoscopic procedure with three ports, lobectomies were carried out by video-assisted minithoracotomy with 7-10cm incision. Results For lim ited resect ion, the average operat ive durat ion w as 110m in (30-180m in) , blood loss was 60m l (10-300m l) , none had intraoperative blood transfusion needed. Conversion to minithoracotomy occurred in 2 patients. Postoperative bleeding happened in one case, which was controlled by medicine. Average length of stay was 6. 5 days. For lobectomy, the average operation time was 145 min (80-260min) , blood loss was 190ml (50-500m l) , no intraoperative blood tansfusion needed. Conversion to tranditional thoracotomy occurred in 3 patients, pneumonia occurred in 2 patients, delayed healing of mini-incision occurred in 2 patients. One diaphragmat ic hernia and one active bleeding after operat ion underwent second thoracotomy. Average length of postoperative stay was 7. 4 days (4-13d). For bilateral lobectomies, the average operative duration was 330min (270-415m in) , postoperative length of hospital stay was 10.7days (8-16d). No perioperative death occurred. Conclusion VATS for benign pulmonary disease is miniinvasive and safe, the pat ients recover quickly. It could be the choice of operation for selected patients in equipped center.
Abstract： Objective To summarize our surgical experience of tetralogy of Fallot（TOF） with anomalous coronary artery（ACA）， explore diagnostic method of ACA， and evaluate surgical strategy choices and clinical outcomes of right ventricular outflow tract（RVOT） reconstruction. Methods From January 2004 to January 2010， 29 patients with TOF and ACA underwent total correction in Wuhan Asia Heart Hospital. There were 18 male patients and 11 female patients with their median age of 7 years （5 months to 33 years）and median body weight of 18 （5 to 51） kg at operation. Their preoperative arterial oxygen saturation was 65%-91%. One patient underwent RVOT enlargement and repair of ventricular septal defect via right atrial approach. Three patients underwent RVOT enlargement， repair of ventricular septal defect and main pulmonary artery enlargement using autologous pericardium patch via right atrial approach. Three patients received pulmonary artery translocation （REV） technique. Five patients received double outlet technique. Eleven patients underwent RVOT enlargement via incisions above， below or beside coronary arteries （single patch or two patch technique）. Six patients underwent RVOT reconstruction using trans-annular patch after coronary artery bypass grafting. Results The median cardiopulmonary bypass time was 78 （65-102） min， median aortic crossclamp time was 50（40-82） min， and median operation time was 150 （126-178） min. There was no early death or severe coronary artery injury. Two patients underwent reexploration because of postoperative bleeding. Two patients had low cardiac output and were both cured with inotropic support. The median follow-up period was 51 （21-83）months and there was no late death during follow-up. All the patients were in New York Heart Association （NYHA） classⅠduring follow-up， their left ventricular ejection fraction was normal， there was no sign of myocardial ischemia in electrocardiogram， and their arterial oxygen saturation was 96%-99%.Mean early RVOT gradient （△P） was 19 （8-38） mm Hg， and the RVOT gradient （△P） did not increase during follow-up. Conclusion Preoperative diagnosis of ACA in TOF patients can be made by 64-slice multislice compute tomography （64-MSCT）. Proper surgical strategy for RVOT reconstruction should be chosen according to the distribution of coronary arteries to achieve satisfactory surgical outcomes.
Abstract： Objective To evaluate clinical outcomes of painless flexible fiberoptic bronchoscopy in the treatment for pulmonary complications in postoperative pediatric patients with congenital heart diseases. Methods We retrospectively analyzed clinical data of 58 patients who received fiberoptic bronchoscopy for pulmonary complications after surgical repair for atrial septal defect， ventricular septal defect， tetralogy of Fallot， double outlet right ventricle or transposition of the great arteries in First Affiliated Hospital of Harbin Medical University From August 2009 to February 2012. There were 26 male patients and 32 female patients with their age ranging from 20 days to 2 years. Olympus xp-60 fiberoptic bronchoscopy was used for removal of airway secretions and bronchial alveolar lavage under anesthesia with propofol， fentanyl and lidocaine. Pulse oximetry， respiratory sound and chest X-ray changes were observed. Results The examination time of painless fiberoptic bronchoscopy was 10-25 minutes in the 58 patients. After removal of airway secretions by fiberoptic bronchoscopy， their respiratory status improved significantly， pulse oxygen saturation increased by 5%-12%， and their pulmonary crackles were significantly reduced. In 29 patients with atelectasis， their pulmonary lobes demonstrated significant reexpansion in chest X-ray reviews on the next day after fiberoptic bronchoscopy， and 8 patients received another fiberoptic bronchoscopy treatment on the next day to achieve complete pulmonary reexpansion. One patient with severe pulmonary hypertension （PH） stayed in intensive care unit （ICU） for 6 days， 3 patients with transposition of the great arteries stayed in ICU for 5 days， 3 patients with double outlet of right ventricle and moderately high PH stayed in ICU for 4 days， and all the other patients were discharged from ICU within 48 hours after admission. There was no severe complication related to fiberoptic bronchoscopy， except 2 patients with minor nasal mucosa bleeding who were cured with hemostatic drugs and local compression. Conclusion Painless flexible fiberoptic bronchoscopy can significantly enhance clinical outcomes and shorten ICU stay for postoperative pediatric patients with congenital heart diseases.
目的 總結單心室瓣膜反流的外科治療經驗，觀察治療效果。 方法 回顧性分析2006年7月至2012年1月上海交通大學醫學院附屬新華醫院61例單心室患者的臨床資料，其中男36例，女25例；手術年齡2個月至 20歲；體重2～58 kg。右心室型41例，左心室型13例，未定型型7例。根據瓣膜反流程度不同分為3組，無/微量反流組：28例，瓣膜未行處理；輕/中度反流組：21例，瓣膜未行處理；重度反流組：12例，手術同期行瓣膜成形。收集所有患者住院及隨訪資料，分析輕/中度反流組、重度反流組瓣膜反流變化趨勢，以及影響瓣膜反流的因素。結果 住院死亡5例，住院死亡率8.2% （5/61）。重度反流組患者行瓣膜成形術后反流程度較術前明顯減輕（由術前4.00級下降至術后2.08級）。隨訪56例，隨訪時間6～38個月，重度反流組隨訪10例，隨訪期間死亡2例，其余8例中重度反流2例，中度反流3例，輕度反流2例，微量反流1例；瓣膜反流程度增加趨勢明顯（由術后平均2.08級增加至平均2.75級）。輕/中度反流組隨訪19例，隨訪中無死亡，其中反流程度增加至重度3例（原1例輕度反流，2例中度反流），反流程度由輕度增加至中度3例，瓣膜反流程度由術后平均2.33級增加為平均2.58級。輕/中度反流組瓣膜反流增加率與無/輕微反流組比較差異無統計學意義（瓣膜反流增加率為31.5% vs. 19.2%，χ2=0.36，P=0.55）。單因素分析結果顯示，瓣膜反流增加者在隨訪過程中心功能較瓣膜反流無變化或減輕者明顯降低（術后左心室射血分數53.11%±5.61% vs. 59.65%±3.32%，t =-5.49，P=0.00），而左心室舒張期末容積較瓣膜反流無變化或減輕者明顯增加（t =2.58，P=0.01）。 結論 單心室合并重度瓣膜反流行瓣膜成形術近期效果較好，但隨著心功能下降、心室擴張，瓣膜反流程度加重趨勢明顯；輕/中度瓣膜反流可暫不進行處理，但部分患者瓣膜反流有增加趨勢，提示應注重術后隨訪。
Objective To investigate clinical outcomes of one-stage repair for patients with persistent truncus arter-iosus who missed optimal timing of surgery. Methods We retrospectively analyzed clinical data of 12 patients with persistent truncus arteriosus who had missed optimal timing of surgery and were admitted to Wuhan Asia Heart Hospital between June 2003 and August 2011. There were 7 male patients and 5 female patients with their median age of 4.5 （0.6-14.0）years and median body weight of 23 （6-36）kg. All the patients underwent one-stage surgical repair. There were 9 patients with Van Praagh type A1，2 patients with type A2，and 1 patient with type A4 persistent truncus arteriosus. There were 2 patients with anomalous origin of coronary artery，2 patients with moderate truncal valve insufficiency，and 3 patients with moderate tricuspid valve insufficiency which required concomitant surgical repair. All the patients received preoperative right heart catheterization which showed severe pulmonary hypertension. The median pulmonary-systemic blood flow ratio （Qp/Qs ratio） was 2.42 （1.50-5.26），and median pulmonary vascular resistance was 8.1 （4-12） Wood units. All the patients showed a positive pulmonary vasodilator response to oxygen. Right ventricular outflow tract （RVOT） reconstruction was achieved using a valved conduit in 7 patients and a valved patch in 5 patients. Results There was no in-hospital death in this group. Three patients had transient pulmonary hypertensive crisis during postoperative intensive care and were healed after proper treatment. Early postoperative pulmonary artery pressure monitoring in all the patients showed that main pulm-onary artery systolic pressure/radial artery systolic pressure was 0.48±0.12. All the 12 patients were followed up for 48（12-91）months. There were 10 patients with New York Heart Association （NYHA） classⅠand 2 patients with NYHA classⅡ during follow-up. One patient received reoperation for residual ventricular septal defect and right ventricular failure.Two patients required long-term medication treatment for high pulmonary vascular resistance and right ventricular failure. The latest echocardiography during follow-up showed that average pressure gradient across RVOT was 21 （16-42） mm Hg in patients with valved conduit for RVOT reconstruction and 18 （10-28） mm Hg in patients with valved patch for RVOT reconstruction. None of the patients required reoperation for RVOT obstruction. Pulmonary regurgitation was less than moderate degree in all the patients. Two patients with anomalous origin of coronary artery didn’t have symptoms or electrocardiogram changes of myocardial ischemia during follow-up. Conclusion For patients with persistent truncus arteriosus who missed optimal timing of surgery， one-stage repair can achieve good early and intermediate clinical outcomes，but long-term follow-up is needed to observe truncal valve regurgitation and right ventricular function.
Abstract： Objective To investigate the effect of preoperative oral carbohydrate （CHO） administration on perioperative risks of patients with surgical thoracic oncology，and provide evidence for establishing new scientific preoperative fasting strategy.Methods?In this prospective study， from July to September 2010，32 out of 65 enrolled patients with surgical thoracic oncology in Department 1 of Thoracic Surgery，Cancer Hospital of Peking University， were randomly allocated to preoperative experiment group （fasting overnight and oral 12.5% dextrose 400 ml administration 2 h before anesthesia induction） or control group （fasting overnight and water deprivation from midnight）. Clinical data were collected including subjective evaluation of thirst and hunger measured by visual analogue scale （VAS）， blood glucose level（BGL），serum insulin level， homeostasis model assessment insulin resistance（HOMA-IR），postoperative length of hospital stay （LOS） and complications.Results?Sixteen patients were enrolled in each group. VAS scores of thirst and hunger of the preoperative experiment group at 1 h before anesthesia induction were significantly lower than those of the control group（24 vs. 49，24 vs. 62 ，P=0.000）. BGL（8.59±0.43 mmol/L vs. 5.59±0.43 mmol/L， P=0.000）， serum insulin level （24.33±1.80 mIU/ ml vs. 16.28±1.80 mIU/ml， P=0.004）and HOMA-IR（9.23±0.77 vs. 4.03±0.77，P=0.000）of the preoperative experiment group before anesthesia induction were significantly higher than those of the control group，and these three variables of the preoperative experiment group returned to baseline level soon after surgery. There was no statistical difference in postoperative LOS and complication rate between the two groups （P＞0.05）.Conclusion?Preoperative oral CHO treatment is safe for non-diabetic patients with surgical thoracic oncology， can alleviate their subjective discomfort，decrease insulin resistance， and ameliorate their perioperative stress and metabolism.
Objective To investigate diagnosis and treatment strategies of patients with pulmonary tuberculosis （TB） complicated by Aspergillus infection. Methods Clinical data of 38 patients with pulmonary TB complicated by Aspergillus infection who underwent surgical treatment from January 2008 to December 2010 in Chengdu Infectious Disease Hospital were retrospectively analyzed. There were 23 male patients and 15 female patients with their average age of 37.8 （23-59） years. Preoperatively，all the patients received regular anti-TB treatment for more than 2 weeks，and patients with definite Aspergillus infection received anti-Aspergillus therapy for more than 3 days with consultation of infectious disease physicians. After above treatment，26 patients underwent lobectomy，1 patient underwent right pneumonectomy，and 11 patients underwent left pneumonectomy. All the patients were followed up at the outpatient department after discharge. They were evaluated every 2 weeks in the first 3 months，every 1 month after 3 months，and every 6 months after 1 year. During follow-up，they received acid-fast bacillus smear and sputum culture to check Aspergillus，as well as CT chest scan. Results All the patients successfully received surgical resection of the pulmonary lesion without perioperative death or severe complication. Postoperative pathology examination confirmed pulmonary TB with Aspergillosis infection in all the 38 patients，whose basic diseases included TB cavity in 17 patients，TB-destroyed lung in 12 patients，and post-TB bronchiectasis in 9 patients. All the patients were followed up after discharge for 1.5-4.5 years. During follow-up，they received regular anti-TB therapy for adequate duration in addition to antifungal medications such as voriconazole. None of the 38 patients had recurrence of Aspergillus infection or pulmonary TB. One patient had hemoptysis which was controlled after proper treatment during follow-up. Conclusion Missed diagnosis rate of pulmonary TB complicated by Aspergillus infection is high. Surgical resection of the pulmonary lesion and postoperative medication treatment are the most effective treatment strategies for patients with pulmonary TB complicated by Aspergillus infection.
Abstract： Objective To investigate clinical characteristics， surgical strategy and prognosis of pulmonary pleomorphic carcinoma， and improve the diagnostic and therapeutic level of pulmonary pleomorphic carcinoma. Methods We retrospectively analyzed clinical data of 7 patients with pulmonary pleomorphic carcinoma who underwent surgical resection from January 2006 to August 2011 in West China Hospital of Sichuan University. There were 5 male patients and 2 female patients with the male/female ratio of 2.5︰1.0 and the mean age of 58.85 （43-69） years old. We also conducted a literature review through PubMed using pulmonary pleomorphic carcinoma and surgery as the key words， and 8 patients with integral clinical data from 2005 to 2011 were identified. There were 7 male patients and 1 female patient with the male/female ratio of 7︰1 and mean age of 70.25 （51-79） years old. All the patients underwent surgical resection and systemic lymph node dissection. Results The mean age of this group was 64.93 （43-79） years old. Among the 15 patients， there were 12 males and 3 females with the male/female ratio of 4︰1. The main symptoms were cough， blood in phlegm， hemoptysis and chest pain. Pathology diagnosis confirmed pleomorphic carcinoma in all the patients. Among the 7 patients of our hospital， there were 3 patients with spindle cell with squamous cell carcinoma， 2 patients with spindle cell with adenocarcinoma， and 2 patients with spindle cell with large cell carcinoma and adenocarcinoma. During follow-up， 3 patients died with the longest survival time of 49 months， and the other 4 patients were still alive. Among the 8 patients in the literature review， there were 4 patients with spindle cell with squamous cell carcinoma， 1 patient with spindle cell with adenocarcinoma， 1 patient with spindle cell with large cell carcinoma and squamous cell carcinoma, and 2 patients with spindle cell with adenocarcinoma and squamous cell carcinoma. During follow-up， 5 patients died with the longest survival time of 22 months， and the other 3 patients were still alive. Conclusion Pulmonary pleomorphic carcinoma is extremely rare and surgical resection is an effective treatment strategy for it.
