Have You Seen SAM?

Abstract

IntroductionSegmental arterial mediolysis (SAM) is a rare, non-atherosclerotic, non-inflammatory vascular disease mostly affecting medium to large sized abdominal arteries which may cause aneurysms, stenosis, and haemorrhage.ReportA case is reported of a patient with SAM affecting the renal arteries bilaterally, where the diagnosis was made by excluding other inflammatory, immunological, and infectious mimickers.DiscussionAs SAM carries a significant mortality and morbidity from end organ ischaemia, infarction, or haemorrhage, it should be considered in any patient presenting with abdominal pain.

Segmental arterial mediolysis (SAM): Systematic review and analysis of 143 cases

“…Reported methods for diagnosing SAM. (A) A total of 121 cases were identified from the 66 case reports 4,5,8–10,13,22–81 with unique diagnostic strategies. For publications detailing multiple patients, a case was counted as unique if the diagnostic strategy was specifically based on that patient’s presentation and was considered redundant and only recorded once if the same strategy was applied to multiple patients in the report.…”

“…A total of 126 unique cases were identified from 66 different case reports and case studies (Supplementary Table 1). 4,5,8–10,13,22–81…”
