The aim of this paper was to present a diagnostic possibilities and its efficiency rate in patients with vascular complications of Ehlers–Danlos syndrome who suffered from artery dissection resulting in acute brain or limb ischemia. We analysed three patients with diagnosed Ehlers–Danlos syndrome who were referred to radiology department for diagnostic imaging of affected vascular beds, each experienced brain ischemia. The paper also aims at offering some general recommendations for patients suffering from possible complications of type IV Ehlers–Danlos syndrome basing on our own experience and available literature data.
