Coil embolization with open frozen hybrid graft for complex left subclavian artery/proximal descending aortic aneurysm in a young patient.

An LSCA aneurysm is a rare disease. When and how to operate are debated. While open surgery was initially considered the sole option, emerging endovascular techniques have been described. The present report describes a novel hybrid technique to treat an LSCA aneurysm combined to a proximal descending aneurysm in a young 25-year-old patient.
