Gouveia e Melo R, Duarte GS, Lopes A, et al. - Researchers investigated the overall prevalence of synchronous and metachronous TAA (thoracic aortic aneurysms) (SM‐TAA) in patients with a known abdominal aortic aneurysm (AAA) as well as explored the characteristics of this sub‐population, via this systematic review and meta‐analysis. All population‐based studies describing the prevalence of SM‐TAAs in patients with AAA were identified from MEDLINE, EMBASE, and CENTRAL (Cochrane Central Register of Controlled Trials). Six studies were analyzed. In AAA patients, the pooled‐prevalence of SM‐TAA was found to be 19.2%. A 2‐fold raised risk of having an SM‐TAA was identified in women with AAA vs men. A 43% reduced risk of having SM‐TAA was noted in relation to diabetes mellitus. Because an SM‐TAA will be encountered in a fifth of AAA patients, therefore, routine screening of SM‐TAA as well as their clinical effect should be more thoroughly examined in patients with known AAA.
