A Case of Pelvic Lymphatic Effusion Managed with N-butyl-2-cyanoacrylate/Lipiodol Embolization through an Inguinal Lymph Node

Lymphatic ascites developed in a woman in her fifties after she underwent total hysterectomy, bilateral salpingo-oophorectomy, and lymph node dissection for endometrial carcinoma. Approximately 500-1,000 mL of opalescent fluid was drained daily. Initially, dietary fat restrictions failed to reduce ascites. Two lipiodol lymphangiographies identified leaks from the iliac lymphatic vessels but were only partially successful at occluding these leaks. Octreotide injection and clamping of the drainage tube were attempted without success. On postoperative day 68, a mixture of lipiodol and n-butyl-2-cyanoacrylate was injected to embolize the leakage point, significantly reducing symptoms. The patient was discharged on day 76, and follow-up computed tomography two months later showed complete resolution of ascites. One year after surgery, the patient remained symptom-free.
