RESUMEN
Objective:To evaluate the techniques and short-term outcomes of pericardial autologous angioplasty for the reconstruction of mediastinal large vessels in the treatment of locally advanced malignant thymoma.Methods:We retrospectively analyzed the clinical data of 6 patients with locally advanced malignant thymoma who received autologous pericardial transplantation for mediastinal great vascular reconstruction in the same treatment group of Department of Thoracic Surgery, the Affiliated Hospital of Qingdao University from April 2017 to October 2018.Results:The operative time of malignant thymoma patients receiving autologous pericardial vascular reconstruction was(192.3±32.5)min, intraoperative blood loss was(105.0±27.5)ml, thoracic drainage time was(4.5±1.5)days, and postoperative hospital stay was(5.3±2.5)days. The postoperative quality of life of the patients was satisfactory. Angiography showed that the reconstructed vessels of the left inus vein were occluded in 1 patient 10 months after the operation, and the reconstructed vessels were unobstructed in the other patients. The average follow-up time of the patients was 34.3 months after surgery. One patient developed chest wall metastasis 23 months after surgery, and his condition was stable after receiving local radiotherapy. The other 5 patients did not occur local recurrence or distant metastasis.Conclusion:The application of autologous pericardium for the reconstruction of mediastinal great vessels in the treatment of malignant thymoma is a safe and effective method, and its clinical application prospect is worth expecting.
