We read with great interest the retrospective case series by Akfaly et al., which presents the largest known cohort of inferior mesenteric artery aneurysms to date.1 The authors are to be acknowledged for delineating the differing clinical behavior of aneurysms associated with segmental arterial mediolysis versus atherosclerosis and for integrating celiomesenteric inflow status into treatment stratification. This pathophysiologic framing adds clinical depth to an area previously reliant on size alone.
A Sun, study studied this question.
