Treatment of a retroperitoneal lymphocele after lumbar fusion surgery with intralesional povidone iodine: technical case report.

Abstract

This case report illustrates an uncommon complication from the retroperitoneal exposure of the lumbar spine. The diagnosis and management of a retroperitoneal lymphocele is presented. The lymphocele was treated with intralesional povidone iodine (Betadine; Purdue-Frederick, Norwalk, CT), which eradicated the lesion and provided symptomatic relief to the patient. A young woman developed an iatrogenic, rapidly progressive spondylolisthesis after having undergone three previous lumbar surgeries for radiculopathy at the L5-S1 level. A back-front-back approach was used for operative reduction and fusion of the spondylolisthesis. The patient's postoperative course was complicated by a retroperitoneal lymphocele. She presented with symptoms of urinary urgency and incontinence. The lymphocele was successfully treated with repeated drainage and sclerosis with povidone iodine. The patient ultimately developed a solid fusion, and her pain resolved. A retroperitoneal lymphocele is an uncommon complication caused by the surgical exposure of the lumbar spine when a ventral approach is used. In this case, it was diagnosed and treated without further surgical intervention.
