Zhu Y, et al. - In this retrospective study, researchers sought the patients who are at high risk of developing postimplantation syndrome (PIS) after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection. For this purpose, they analyzed 646 patients who underwent TEVAR for type B aortic dissection between January 2010 and December 2015 at the Guangdong General Hospital. Independent predictors of PIS were age <60 years, comorbid hypertension, >1 stent graft placed, arch vessel bypass and Ankura stent graft placement. The number of independent predictors determined the increases in the prevalence of PIS in a stepwise manner.
