Delayed fatal rupture of vertebral artery after treated with flow-diverter in fibromuscular dysplasia patient: A case report and review of the literature.

Abstract

Fibromuscular dysplasia (FMD) is a noninflammatory arterial diseases that affects predominantly women. Multiple studies have demonstrated an increased prevalence of FMD in patients who experience carotid or vertebral artery dissection (VAD). This case report presents a 57-year-old female who presented with a headache and was diagnosed with partially thrombosed giant aneurysm of vertebral artery. This aneurysm was successfully treated with flow-diverter and coil, but new onset rupture of vertebral artery was detected two weeks later, leading to internal trapping. This case report underscores the need for awareness and understanding of treatment of dissection and aneurysm in patient who is suspected FMD.
