  • Title: Preoperative Transvenous Liquid Embolization for a Symptomatic Lumbar Spinal Epidural Varix Mimicking Radiculopathy.
    Author: Kerolus MG, Kramer DE, Turel MK, Malik R, Fessler RG, Chen M.
    Journal: Neurol India; 2022; 70(3):1176-1179. PubMed ID: 35864659.
    Abstract:
    BACKGROUND: Symptomatic spinal epidural veins (SEV) are a rare cause of neurologic dysfunction. Treatment is centered upon addressing the underlying venous pathology to relieve mechanical compression of the neurologic structures. However, open surgical ligation is often associated with considerable blood loss. OBJECTIVE: We discuss a unique case of a large symptomatic epidural venous varix and potential treatment strategy. METHODS AND MATERIALS: A 15-year-old female presented with a 1-year history of left L5 radicular pain and weakness. Lumbar MRI demonstrated a central L5/S1 herniated disc and a large extradural anomalous SEV compressing the exiting left L5 nerve root at the L5/S1 neuroformina. The SEV was treated using a transvenous liquid embolic agent providing symptomatic relief. At 16-months follow-up, she reported recurrent symptoms. She ultimately underwent a left L5/S1 MIS decompression without complication. CONCLUSION: Transvenous liquid embolization of large symptomatic SEV may provide temporary neurologic relief and decrease morbidity associated with open surgical treatment options.
