TEVAR for complicated and uncomplicated type B aortic dissection—Systematic review and meta‐analysis

Background Type B aortic dissection (TBAD), is defined as a involving the aorta distal to left subclavian artery with ascending and arch not affected. TBAD classified due time frame presence of complications. Complicated (co-TBAD) patients have greater mortality rate than uncomplicated (un-TBAD) thoracic endovascular repair (TEVAR) considered gold-standard intervention for these clinical challenges. Methods We undertook systematic review literature regarding TEVAR in co-TBAD un-TBAD. A comprehensive search was undertaken across four major databases evaluated assessed until June 2020. Results total 16,104 were included study (7772 8352 un-TBAD). significantly higher proportion comorbidities seen compared Acute more frequent group (73.55% vs. 66.91%), while chronic common un-TBAD (33.8% 70.73%). Postprocedure stroke (5.85% 3.92%; p < .01), postprocedural renal failure (7.23 11.38%; .01). No difference observed in-hospital however 30 days group. One-year survival but this 5-year survival. Conclusion In our analysis we can appreciate that despite cohort, there no between two groups did any difference.
