AbstractAim: This meta-analysis study aimed to compare the efficacy and safety of TEVAR versus OCSR for TBAD patients.Methods: We systematically searched PubMed, EmBase, and the Cochrane library to identify studies compared the effectiveness of TEVAR and OCSR in TBAD patients from the inception up to July 2019. The summary results were calculated using a random-effects model.Results: The electronic search identified 1,894 studies, and 18 studies with 9,664 TBAD patients were included. We noted patients received TEVAR were associated with a reduced risk of in-hospital mortality, acute renal failure, respiratory failure, and bleeding as compared with OCSR, whereas no significant differences between groups for the risk of stroke, myocardial infarction, paraplegia, mesenteric ischaemia/infarction, reinterventions, sepsis, and spinal cord ischaemia.Conclusions: The findings of this meta-analysis study suggested that TEVAR resulted in more short-term survival benefits. Moreover, the reduced risk of acute renal failure, respiratory failure and bleeding was detected in TEVAR group. The treatment effects of TEVAR versus OCSR on specific complications should be further verified by a study with high-level of evidence.Key messageComprehensive collected studies investigated the treatment effectiveness between TEVAR and OCSR for TBAD patientsTEVAR resulted in more survival benefits, in addition to lower risk of acute renal failure, respiratory failure and bleedingThe results of stratified analyses according to patients' characteristics were conducted.
