Multiple arterial thromboses due to cystic medial degeneration Erdheim-Gsell: A case report.

RATIONALE

Cystic medial degeneration Erdheim-Gsell is a vascular pathology mainly of the large vessels, which is mostly associated with Marfan syndrome or Ehlers-Danlos syndrome. The clinical findings of this entity are aneurysms of the aorta or large peripheral arteries which usually present in an acute setting due to rupture of an aneurysm.

PATIENT CONCERNS

We present a case of a 43-year-old Caucasian male with histologically proven cystic medial degeneration of the lower limb vessels mimicking peripheral artery occlusive disease. Despite antiplatelet and anticoagulant treatment, the patient suffered multiple vascular stenosis and occlusions.

DIAGNOSES

Multiple arterial stenoses and thromboses leading to peripheral artery occlusive disease caused by cystic medial degeneration Erdheim-Gsell.

INTERVENTIONS

Multiple surgical and endovascular interventions including bypass graft and intra-arterial thrombolysis as well as oral antiplatelet and anticoagulant therapy.

OUTCOME

Despite dual antiplatelet therapy, anticoagulant therapy with rivaroxaban and multiple surgical and endovascular interventions, the patient developed recurrent arterial thromboses. The patient did not suffer further thrombotic events since clopidogrel and phenprocoumon were administered.

LESSONS

Clinical presentation of cystic medial degeneration Erdheim-Gsell mimicking peripheral artery occlusive disease is very unusual. Due to the fragile vessel wall, patients with cystic medial degeneration might have a higher risk to develop arterial thromboses, even under antiplatelet therapy or anticoagulant treatment.
