title: Pediatric sciatic neuropathies due to unusual vascular causes.
abstract: Four cases of pediatric sciatic neuropathies due to unusual vascular mechanisms are reported. Pediatric sciatic neuropathies were seen after umbilical artery catheterization, embolization of arteriovenous malformation, meningococcemia, and hypereosinophilic vasculitis. Electrophysiologic studies demonstrated abnormalities in motor studies of peroneal and tibial nerves. Sensory studies demonstrated abnormalities of sural and superficial peroneal nerves. Results of needle electromyography were abnormal in sciatic-innervated muscles. Prognosis was variable and depended on the severity of the initial nerve injury.
