Abstract
Ehlers-Danlos syndrome (EDS) is a rare connective tissue disorder, which is characterized by fragility of the skin, blood vessels, and joints. Arterial rupture is one of the most severe complications in patients with vascular type EDS. We herein report a case in which bilateral posterior tibial artery aneurysms led to the diagnosis of vascular type EDS. This case was a 27-year-old male with swelling of the left calf. His brother had an aneurysm of the carotid artery. He had thin skin with visible veins and skin hyperextensibility. Computed tomography showed bilateral posterior tibial artery aneurysms, sized 10 mm, and a left aneurysm which may have ruptured. These findings were suggestive of vascular type EDS, and conservative management was performed. After the treatment, his clinical symptoms were relieved, and no further rupture of the aneurysms occurred. Patients with vascular type EDS should be promptly evaluated, and the treatment must take into account the fragility of the patient’s skin, connective tissue, and blood vessels.
