Segmental arterial mediolysis: Literature review focused on radiologic findings and management

Abstract

Segmental arterial mediolysis (SAM) is a rare disease which can have catastrophic consequences due to massive hemorrhage or dissecting hematomas. The pathophysiology of this disease is not well-known, and the symptoms vary according to the organs involved. In many patients the diagnosis is based on the clinical and radiologic features rather than the pathologic confirmation. The catheter-based endovascular technique can be an interventional treatment option for SAM, as well as surgical management.
