Percutaneous Lymphatic Embolization as Primary Management of Pelvic and Retroperitoneal Iatrogenic Lymphoceles.

Abstract

PURPOSE:

To evaluate the efficacy of lymphatic embolization (LE) in decreasing catheter output and dwell time in iatrogenic lymphoceles after percutaneous catheter drainage.

MATERIALS AND METHODS:

Retrospective review of patients who underwent intranodal lymphangiography (INL) with or without LE for management of iatrogenic lymphoceles between January 2017 and November 2020 was performed. Twenty consecutive patients (16 men and 4 women; median age, 60.5 years) underwent a total of 22 INLs and 18 LEs for 15 pelvic and 5 retroperitoneal lymphoceles. Lymphatic leaks were identified in 19/22 (86.4%) of the INLs. Three patients underwent INL only because a leak was not identified or was identified into an asymptomatic lymphocele. One patient underwent repeat INL and LE after persistent high catheter output, and 1 patient underwent repeat INL with LE after the initial INL did not identify a leak. Catheter output was assessed until catheter removal, and changes in output before and after the procedure were reported. The patients were followed up for 2-30 months, and procedural complications were reported.

RESULTS:

The median catheter output before the procedure was 210 mL/day (50-1,200 mL/day), which decreased to a median of 20 mL/day (0-520 mL/day) 3 days after the procedure, with a median output decrease of 160 mL (0-900 mL). The median time between INL with LE and catheter removal was 6 days, with no recurrence requiring redrainage. Four patients experienced minor complications of low-grade fever (n = 2) and lower limb edema (n = 2).

CONCLUSIONS:

Lymphangiogram and LE are safe and effective methods for the management of lymphoceles.
