We aimed to evaluate the efficacy of percutaneous embolization after lymphangiography using C-arm cone-beam computed tomography (CBCT) performed at the site of lymphatic leakage in patients with postrenal transplant lymphocele.
Between July 2014 and August 2017, 13 patients not responding to percutaneous ethanol sclerotherapy and conservative treatment for recurrent lymphocele after renal transplant were included. The mean age of the patients was 56.38 ± 9.91 (range, 36-70) years, and it comprised 9 men and 4 women. All patients underwent intranodal lymphangiography. C-arm CBCT-guided percutaneous embolization was performed in patients with confirmed lymphatic leakage. Patients who had no lymphatic leakage underwent drainage with fibrin glue injection.
Lymphatic leakage was observed in 9 patients after lymphangiography, and they underwent CBCT-guided percutaneous N-butyl-2-cyanoacrylate embolization. The volume of lymphatic drainage reduced to less than 10 mL in 8 patients. One patient who was not responding to embolization was treated surgically, after percutaneous drainage and fibrin glue injection. Lymphatic leakage was not observed in 4 patients after lymphangiography. Of these, 3 patients showed a reduction in the amount of lymphatic drainage after lymphangiography. All 4 patients underwent percutaneous drainage and fibrin glue injection. One patient did not respond to the treatment and was treated surgically. Prelymphangiography and postlymphangiography and embolization, the volume of lymphatic drainage was 113.07 ± 21.75 mL, and 53.84 ± 30.96 mL, respectively, and statistically significant decrease was detected (P < 0.005).
Lymphangiography and CBCT-guided percutaneous embolization procedures might be an effective treatment method for patients with lymphocele refractory to treatment.
Lymphangiography and C-arm cone-beam computed tomography guided percutaneous embolization procedures may be an effective treatment method for patients with lymphocele refractory to treatment.
