Extracranial Vertebral Artery Dissecting Aneurysm with Snowboarding: A Case Report
She was admitted for observation under the neurosurgery service and discharged 24 h later. She was placed on 500-mg naprsoyn twice a day, robaxin 500 mg every 6 h as needed, and 325 mg of aspirin daily. She was to follow-up with her primary care provider and have a repeat magnetic resonance angiography (MRA).
At follow-up with her primary care manager (PCM), she stated her pain was worse upright but relieved lying down. No lumbar puncture was performed. She also had elevated blood pressures of 156/100 mm Hg in the right arm and 136/100 mm Hg in the left arm. Her physical examination remained normal. She was started on 25 mg of propranolol and was evaluated for fibromuscular dysplasia with an MRA of her renal arteries, which results reported as normal. Symptoms gradually improved over a 3-wk time span. Propranolol was stopped at this time as her blood pressure normalized.
Follow-up imaging with MRA at 7 wk showed interval improvement and an adequately patent right vertebral artery with minimal luminal irregularity. Final follow-up imaging 3 months later was reported as normal. Her aspirin was stopped at this time.
