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

Abstract

A B S T R A C TSegmental 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.

“…Segmental arterial mediolysis is a rare nonatherosclerotic, noninflammatory cause of SAPs. 1 First reported in 1976 by Slavin and Gonzalez-Vitale, 2 the disease affects all age groups and has a slight male preponderance. The etiology of SAM is still unclear.…”
