Endovascular stent graft exclusion of a thoracic arteriovenous malformation in a patient with Cobb syndrome

Cobb syndrome is a rare neurocutaneous disorder characterized by spinal vascular abnormalities in association with a vascular lesion of the skin at the same metamere. Patients present after the onset of symptoms such as paraplegia, back pain, and, less commonly, fatigue due to heart failure. Available treatment options to date have included neurosurgical resection and endovascular embolization. We present a patient with Cobb syndrome with a progressively symptomatic arteriovenous malformation involving the thoracic vertebrae and left hemithorax, with extensive blood supply from the T3 to T10 intercostal arteries, and demonstrate successful endovascular thoracic stent graft placement and coil embolization.
