Treatment of lymphatic leakage after retroperitoneal tumor resection by lymphangiography and embolization

Abstract

Lymphatic leakage is an infrequent but relatively serious complication after resection of retroperitoneal tumors. Different approaches have been attempted in treatment of lymphatic leakage. However, to date none of them have been demonstrated consistently effective. We hereby report our preliminary experience with Lymphangiography and embolization for resolution of Lymphatic leakage after retroperitoneal tumor resection.The patient, a 55-year-old woman with massive retroperitoneal tumor, Computed tomography (CT) revealed that retroperitoneal cystadenoma. After the right ureteral stent was placed, the retroperitoneal tumor resection was performed, postoperatively she presented with lymphatic leakage unresponsive to several treatment measures. From the thirty-seven postoperative day (POD37), the patient underwent Lymphangiography and embolization, which resolved her lymphatic leakage.Lymphangiography is useful for detecting lymphatic leakage occurring after retroperitoneal tumor resection. Furthermore, lymphatic embolization is feasible, effective, and safe for managing leaks demonstrated on lymphangiography.
