  • Surgical Procedures in Five Heart Transplant Patients

    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.

  • Clinical analysis of extracorporeal membrane oxygenation for 26 adult patients after cardiac surgical procedures

    ObjectiveTo summarize the clinical experience of extracorporeal membrane oxygenation (ECMO) in adult patients with cardiac surgery, analyze the risk factors associated with the mortality and other severe complications and to discuss prevention methods of complications during ECMO treatment.MethodsThe clinical data of 26 patients with cardiac surgery, who underwent ECMO because of cardiopulmonary insufficiency ect in Zhongshan Hospital, Fudan University from January 2012 to September 2017, were retrospectively analyzed. There were 19 males and 7 females aged 24–80 (58.0±13.9) years.ResultsTwelve (42.3%) patients successfully weaned from ECMO and six (23.1%) were discharged from hospital. Among 26 patients, 24 received VA ECMO (veno-arterial ECMO), including 5 after heart transplantation, 9 after heart valve surgery, and 3 were successfully weaned from ECMO. Seven patients with valvular surgery underwent ECMO within 48 hours due to refractory low cardiac output syndrome (LCOS). Eight patients underwent major angioplasty, 3 of whom were successfully weaned from ECMO. Four patients underwent coronary artery bypass grafting and other cardiac surgeries. Patients with VA ECMO were treated with femoral vein-femoral artery cannulation except for 2 patients undergoing femoral vein-radial artery cannulation after major angioplasty. Patients with VV ECMO (veno-venous ECMO) underwent femoral vein-jugular vein cannulation. After ECMO support, 10 patients with bleeding occurred, and 5 patients were successfully weaned from ECMO. All patients had transfusion therapy during the assist period, 7 patients had infection after ECMO support, 4 patients suffered severe distal limb ischemia. There was no significant difference in the lactic acid between the survival and the dead patients before and after ECMO support. However, the decline of serum lactic acid in the survivors was faster than that of the dead patients. The trend was the most significant within 6 h after the operation.ConclusionECMO is one of the significant treatments for LCOS and refractory hypoxemia after cardiac surgery. The type of cardiac surgery and the timing of catheter placement are key factors for the success of ECMO. The different ways of ECMO intubation, prevention and control of bleeding during ECMO, monitoring and management of internal environment and the strategies of anti-infection are all important for success of ECMO.

  • Clinical characteristic of aortitis in cardiac surgery in a single center

    ObjectiveTo review and analyze the clinical manifestations of common aortitis in cardiac surgery. MethodsWe screened 41 552 patients who were hospitalized in the Department of Cardiac Surgery of Zhongshan Hospital, Fudan University from 2010 to 2020, analyzed the patients' clinical data, and classified according to the type of diseases. Then we summarized all their clinical manifestations. ResultsIn our center 145 patients were operated for aortitis diseases, including 75 males and 70 females, with the age of 24-76 (45.6±11.3) years. There were 61 patients of Takayasu's arteritis, 51 patients of Behcet's disease, 8 patients of syphilitic aortitis, 8 patients of systemic lupus erythematosus, 2 patients of Kawasaki disease, 4 patients of ankylosing spondylitis, 10 patients of dry syndrome, and 1 patient of scleroderma. ConclusionAortitis is not uncommon in cardiac surgery, and awareness of the disease should be enhanced. So that we can distinguish various types of aortitis and to make proper management to improve patients' prognosis.
