Cerebrovascular complications in Ehlers‐Danlos syndrome type IV

Abstract

Ehlers‐Danlos syndrome (EDS) type IV is an autosomal dominant disorder that results from mutations in the COL3A 1 gene, which encodes chains of type III procollagen. Individuals with this disorder are predisposed to rupture of arteries, the bowel, and the gravid uterus. To assess the frequency of central nervous system complications, we reviewed clinical data concerning 202 individuals with EDS type IV from 121 families in which the diagnosis was confirmed by biochemical or molecular studies. We identified 19 individuals with cerebrovascular complications, which included intracranial aneurysms with secondary hemorrhage, spontaneous carotidcavernous sinus fistula, and cervical artery dissecti..
