Endovascular Outcomes With One-Year Follow-Up of Three Cases of Spinal Arteriovenous Malformation (sAVM) at Cervical, Dorsal, and Lumbar Levels: A Single Institution-Based Case Series of a Rare Entity.

Spinal arteriovenous malformation (sAVM) is a rare vascular disease of the spine, presenting with symptoms of spinal cord involvement including sensory, motor, and autonomic symptoms. Early diagnosis is critical as the disease progresses to cause spinal cord compression, venous hypertension, and compression leading to spinal cord ischemia or infarction. In this case series, we present three cases treated at our institution over one year, with distinctly different anatomical sites of involvement.

Postoperative posterior ischemic optic neuropathy (PION) following right pterional meningioma surgery.

Postoperative visual loss (POVL) is an unpredictable complication of nonocular surgeries. Posterior ischemic optic neuropathy (PION) is particularly feared in spinal surgeries in the prone position. We report a rare case of PION occurring after surgery for a pterional meningioma and discuss the various factors implicated in POVL.
