Thoracic tumor resection combined with SVC replacement using autologous pericardium

Abstract

Abstract Background Invasion of the superior vena cava (SVC) by thoracic tumors and occurrence of SVC syndrome are often encountered in clinical practice; but the prognosis in these cases is poor. Replacement of the SVC with autologous pericardial tissue is rarely performed. In this study, we sought to investigate the postoperative outcomes of this rare procedure. Methods We performed a retrospective analysis of six patients who underwent SVC replacement using autologous pericardial tissue between October 2010 and November 2016. We collected data on the patients’ pathological features, operative characteristics, postoperative outcomes, and survival. Results All six patients were male with an average age of 52 years (range, 18–62 years). Three of the patients had lung cancer, one had stage III thymoma, and two had germinoma. Four of the six patients had mild or moderate superior vena cava compression and no corresponding clinical symptoms. The other two patients had severe compression and obvious symptoms of SVC syndrome, with the typical swelling of the face, eyelids, and upper extremities. All six patients underwent complete tumor resection, with two of the lung cancer patients undergoing right lobectomy and one undergoing right pneumonectomy. With respect to the postoperative outcomes, one patient died, whereas the others did not develop any major complications. At the end of the follow-up period, five of the patients were alive and none of the patients had developed thrombosis in the grafts. Conclusions Our findings indicated that SVC replacement with autologous pericardium is technically feasible and safe, with few postoperative complications and favorable long-term effects. Although it has some limitations, this method appears to be useful in achieving SVC reconstruction of moderate size. SVC replacement with autologous pericardium appears to have the potential for widespread clinical use.
