Early outcomes of the t-branch off-the-shelf multi-branched stent-graft in 542 patients for elective and urgent aortic pathologies – a retrospective observational study.
The t-Branch, a standardized off-the-shelf multibranched stent-graft has been used for the treatment of elective and urgent cases in aortic disease. The aim of this study was to assess the early outcomes in terms of technical success, mortality and morbidity in >500 patients being treated with the t-branch device.A two-center retrospective observational study was undertaken including patients treated using the t-Branch (Cook Medical, Bloomington, IN, USA) in elective or urgent settings for complex AAA and TAAA between 2014-2019 (early experience 2014-16; late 2017-19). Primary endpoints were technical success and early (30-day) mortality and secondary endpoints were early morbidity, endoleak (EL) and target vessel (TV) patency rates. Multivariable regression models were used to determine the independent association of risk factors with i) mortality and ii) spinal cord ischemia (SCI).A total of 542 patients [mean age 70.5±8.5 years; 388 men (72%); mean aneurysm diameter 7.5±2.5 cm] were included (63% elective; 90% thoraco-abdominal aortic aneurysm). The technical success rate was 97% (526/542) [elective 96.7% (328/339) vs urgent 97.6% (208/213)]. The total 30-day mortality rate was 12.3% (8.5% in elective; 15% in symptomatic; 30% in contained rupture). After multivariate regression analysis, mortality rate was associated to older age, (odds ratio [OR], 1.07; 95% confidence interval [CI], 1.03-1.11; P
