  • Application of vascular repair and reconstruction in surgical treatment of superior vena cava syndrome caused by thoracic tumor

    Objective To summarize the clinical experience of vascular repair and reconstruction for treating superior vena cava syndrome (SVCS) caused by thoracic tumor. Methods Between October 2008 and June 2016, 26 patients with thoracic tumor and SVCS were admitted. There were 18 males and 8 females, aged from 27 to 70 years (mean, 45.9 years). Tumor was typed as B1-B3 thymoma in 13 cases, thymic carcinoma in 6 cases, large B-cell lymphoma in 3 cases, T lymphocytic lymphoma in 1 case, malignant teratoma in 1 case, right lung squamous cell carcinoma in 1 case, and carcinoid in 1 case. The tumor diameter ranged from 8 to 15 cm with an average of 10 cm. The patients had different degrees of neck, face, and upper extremity edema, jugular vein distention, and chest wall collateral venous filling. The superior vena cava pressure was 2.45-5.39 kPa. After excision of tumor and invading superior vena cava, 7 patients underwent superior vena cava reconstruction and 19 patients underwent artificial vascular replacement. Results There was no perioperative death, and the symptoms of superior vena cava obstruction were eliminated. Postoperative pulmonary infection, respiratory muscle weakness, and right chylothorax occurred in 4 cases, 1 case, and 1 case respectively. Twenty-four patients were followed up 2-92 months (mean, 37 months), and 2 patients failed to be followed up. At 1, 3, and 5 years, the survival rate was 83.3% (20/24), 41.7% (10/24), and 25% (6/24), respectively. In 6 patients with 5-year survival, there were 1 case of type B1 thymoma, 3 cases of type B3 thymoma, and 2 cases of large B-cell lymphoma. Conclusion For preoperative evaluation of SVCS caused by resectable thoracic tumors, vascular repair and recons-truction technique can be used to quickly and effectively relieve the clinical symptoms and improve the quality of life.
