Answer

FMD generally follows a benign course and is frequently an incidental finding. However, cranial involvement bears worse prognosis because of the occurrence of dissection and strokes and the coexistence of saccular aneurysms. Specific mortality and morbidity data are lacking.

Regarding the risk of recurrent carotid artery dissection, de Bray et al prospectively reviewed 103 consecutive patients with carotid artery dissection with follow-up for an average of 4 years. Of those, 5 had recurrent dissections and 4 of the 5 patients with recurrent dissections were diagnosed with FMD. If considering the presentation of recurrent dissection of the carotid artery, FMD was associated in 80% of their series. [23]
