Transinguinal interstitial (intranodal) lymphatic embolization to treat high-output postoperative lymphocele.

Postoperative lymphoceles may occur after abdominal or pelvic surgery secondary to disruption of lymphatic channels. First-line therapy includes conservative therapy with medical management and dietary restriction. Despite these measures, some patients may have persistent high-output lymphoceles requiring percutaneous aspiration, drainage, or sclerosis. Rarely, surgical evacuation is required. Management of intrathoracic chyle leak by thoracic duct embolization has been well described. Recently, interstitial (intranodal) lymphatic embolization for the treatment of plastic bronchitis has been performed. This case report describes interstitial (intranodal) lymphatic embolization as a novel therapy for high-output postoperative pelvic lymphocele.
