Sequential Symptomatic Arterial Dissections in Multiple Vascular Beds in a Patient with Fibromuscular Dysplasia.

A 60-year-old man was admitted to our hospital because of abdominal pain and disturbed consciousness. Head magnetic resonance imaging showed right vertebral artery dissection and abdominal enhanced computed tomography showed dissection of the superior mesenteric artery. The patient was diagnosed as having fibromuscular dysplasia (FMD) based on conventional angiography. Although multiple vascular bed involvement is observed in approximately 40% of FMD patients, reports of sequential symptomatic dissections in various vascular beds are rare. Patients with FMD and dissection require close observation, and hemodynamic stabilization may prevent not only the further development of dissection, but also subsequent dissection of other arteries.
