Rupture of a median sacral artery aneurysm in a patient with vascular Ehlers-Danlos syndrome

Introduction: Vascular Ehlers Danlos syndrome is a rare connective tissue disease that is associated with various arterial complications.Report: A 25 year old man with vascular Ehlers Danlos syndrome presented with acute lower back pain as a result of a ruptured aneurysm of the median sacral artery (MSA). Prior medical history included several vascular events resulting in a right iliac occlusion. The unusual location of aneurysmal disease of the MSA might be explained by extensive collateral flow recruitment due to this occlusion.Conclusion: Previous vascular events inducing collateral recruitment might justify a more frequent follow up in patients with connective tissue disorders.
