Innominate artery involvement in type iv Ehlers-Danlos syndrome

We report two cases of innominate artery involvement in patients with Ehlers-Danlos syndrome. In the first patient, spontaneous dissection of the innominate artery was treated successfully. In the other, the patient died of spontaneous rupture of the innominate artery in the early postoperative course after operation for aneurysm of the celiac artery. Arterial complications occurring in Ehlers-Danlos syndrome are rare but pose difficult diagnostic and therapeutic problems for the vascular surgeon due to arterial wall fragility.Presented at the Annual Meeting of the Société de Chirurgie Vasculaire de Langue Française, May 18–19, 1990, Nancy, France.
