title: Foot drop after ethanol embolization of calf vascular malformation: a lesson on nerve injury.
abstract: Ethanol is often used in sclerotherapy to treat vascular malformations. Nerve injury is a known complication of this procedure. However, the management of this complication is not well described in literature. This case describes a 10-year-old boy with a slow flow vascular malformation in the right calf who underwent transarterial ethanol embolization following prior unsuccessful direct percutaneous sclerotherapy. The development of a dense foot drop that subsequently recovered is described, and the management of this uncommon but distressful complication is discussed.
