Abstract： Objective To investigate the cause, treatment， and prevention strategy of early left ventricular rupture after mitral valve replacement （MVR）. Methods We retrospectively analyzed clinical data of 7 patients who had early left ventricular rupture after MVR， among a total of 2 638 MVR patients， between May 1981 and November 2010 in General Hospital of Shenyang Military District. There were 2 male patients and 5 female patients with their age ranging from 28 to 71 years old. One patient was New York Heart Association （NYHA） functional classⅡand 6 patients were NYHA functional classⅢ. Preoperative echocardiography showed that their left ventricular ejection fraction （LVEF） was 49%-60% and their left ventricular end diastolic volume （LVEDV） was 29-42 ml. All the patients underwent prothetic valve replacement under moderate hypothermia， general anesthesia and extracorporeal circulation. Results All the 7patients underwent surgical repair for their early left ventricular rupture. There were 2 patients with TypeⅠ， 4 patients with TypeⅡ， and 1 patient with TypeⅢleft ventricular rupture. Four patients died of hemorrhagic shock or low cardiac output syndrome. Three patients were successfully healed and discharged from hospital 7-15 days after the operation. The 3 surviving patients were followed up for 4.5-18.0 years, and they all had good general condition and satisfactory quality of life. No late pseudo-aneurysm was found during follow-up. Conclusions Early left ventricular rupture is difficult to repair with a high mortality. Effective prevention strategy should be applied to avoid it as much as possible. Once left ventricular rupture occurs during the surgery， extracorporeal circulation should be quickly established， and it’s possible to save patients’ life by reliable intracardiac and epicardial repair according to patients’ individual condition.
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.
Objective To investigate clinical features and treatment strategy of cardiac complications caused by permanent pacemaker （PPM） implantation.?Methods?We retrospectively reviewed clinical records of 10 patients with cardiac complications caused by PPM who received surgical treatment in General Hospital of People’s Liberation Army from January 2003 to May 2010. There were seven males and three females with an average age of 62.9 years. One patient had an Atrial demand inhibited pacemaker （AAI） PPM and the other nine patients had a DDD PPM. Cardiac complications included infective endocarditis （IE） in 5 patients, tricuspid insufficiency （TI） in 4 patients and pulmonary artery thrombosis in one patient. According to their respective situation, these patients underwent different surgical treatment such as tricuspid valve plasty （TVP）， tricuspid valve replacement and/or removal of PPM lead and vegetations as part of intensive debridement of the infected area.?Results?Postoperatively， all the patients were successfully discharged. Five patients whose PPM lines and leads were preserved in the surgery had normal PPM function. Three PPM-dependent patients whose PPM leads were removed in the surgery received a PPM reimplantation later. Nine patients were followed up for an average of 5.5 months and all these patients had a significantly improved quality of life. One patient after TVP had mild TI during follow-up. Conclusion Surgical treatment should be performed as early as possible when infection is too severeto control in patients with IE caused by PPM. PPM-induced TI may be hard to be diagnosed preoperatively, and transesophageal echocardiography or surgical exploration should be considered to establish the diagnosis. Measures should be taken to protect PPM if PPM lines and leads are preserved during operation. Patients whose PPM lines and leads are removed during the surgery need to choose a suitable time for PPM reimplantation.
Abstract: Objective To summarize the surgical outcomes and clinical experience of surgical disease for patients having undergone orthotopic heart transplantation. Methods Five cardiac transplant recipients requiring surgical management due to other surgical diseases including acute cholecystitis in 2 patients, acute appendicitis, bilateral mammary hypertrophy and lung tumor in 1 patients, respectively. The mean age of the entire group at the time of reoperation was 44. 6 years (14-60 years) and the average time of operative procedures after transplant was 16. 4 months (4-37 months). Four patients were treated with t riple immunosuppression, including cyclosporine A (CsA ) or tacroimus, mycophenolate mofetil and corticosteroids, respect ively. One patient received double-therapy of CsA and mycophenolate mofetil withearly withdrawal of corticosteroids. All the acute cholecystitis and appendicitis patients underwent open cholecystectomy and appendectomy emergently. Reduction mammaplasty was performed on the bilateral mammary hypert rophy patients. For the lung tumor patient, right upper lobectomy and nodes excision were undertaken radically after the sample proved to be malignancy by the thoracoscopy. Closely surveillance at concentration of CsA or FK506 was performed continueously in o rder to adjust the effect ive blood concentration in a steady way by which acute rejection can be avoided. The pathways which pathogen organisms invading the human body were controlled strictly as well as intension on ant i-infection treatment during perioperative period. Results Four patients discharged to home within 2 weeks. Only one patient needed further treatment in Digestive Department after emergent cholecystectomy due to gastric retention. And shewas discharged after 66 days. No acute reject ions or operative complications such as severe infection or bleeding were found during the perioperative period. The average length of stay was 21. 3 days (8-66 days). During the fo llow -up from 1month to 13months, there was no relapse or allograft disfunction performed on any patients. All of them enjoy quality lives. Conclusions More attention should be paid to regular follow -up after transplantation, by which the emergent surgical diseases can be diagnosed and treated earlier and more effectively. Cardiac transplant recipients who subsequently require surgical intervention do quite well overall. Most of them can obtain excellent surgical outcomes.
