About this study
We aimed to investigate the incidence of reinterventions in patients who underwent thoracic endovascular aortic repair (TEVAR) in multiple centers across Taiwan
Read the detailed description
This study analyzed the multicenter data set for TEVAR procedures performed between 2012 and 2017. Each patient's survival was verified with a query to the national data set. Student's t-test and χ2 analysis were used to compare continuous and categorical variables between the groups that required reintervention and those that did not, respectively. Kaplan-Meier methods were applied to analyze freedom from reintervention and survival rates.We aimed to investigate the incidence of reinterventions in patients who underwent thoracic endovascular aortic repair (TEVAR) in multiple centers across Taiwan
