  • Title: Cauda Equina Arteriovenous Malformation with Bilateral Arterial Feeders.
    Author: Gong M, Luo S, Li J.
    Journal: World Neurosurg; 2022 Jan; 157():88-90. PubMed ID: 34653704.
    Abstract:
    Cauda equina arteriovenous malformation (AVM) is extremely rare. To our knowledge, only 2 cases have been reported previously and are supplied by a unilateral lateral sacral artery (LSA). Here, we report a rare cauda equina AVM at the level of L5-S1, which is supplied by the bilateral LSAs. Given the multiple feeders and complex angioarchitecture, endovascular embolization was performed with Onyx (ev3) successfully. The postoperative course of the patient was uneventful, and symptoms gradually improved. The present case demonstrated the angioarchitecture of the bilateral arterial supplies and venous drainage of the cauda equina AVMs. Cauda equina AVM with bilateral arterial feeders is extremely rare. However, clinicians should be aware of the possibility of this condition and the importance of selective spinal angiography of bilateral LSAs.
