Abstract
Iodized oil-based lymphangiography (LAG) is a well-established diagnostic exam during the workup of postoperative lymphatic leaks. Computed tomography (CT) has been shown to be a useful complement to optimize treatment planning and can easily be performed after conventional LAG. The treatment options for lymphatic leaks include conservative dietary modification, sclerotherapy, embolization, and surgery. We present a case of a 48-year-old man who developed a symptomatic left retroperitoneal lymphatic fluid collection after left nephrectomy, complicated by postoperative retroperitoneal abscess. Retroperitoneal duct leak was confirmed via ultrasound-guided intranodal LAG and post-LAG CT. This leak was successfully managed with N-butyl cyanoacrylate glue embolization of the leaking lymphatics via fluoroscopic-guided catheterization of the leak via percutaneous access through the lymphatic fluid collection.
