What are the risk factors for retrograde aortic dissection after thoracic endovascular aortic repair?
Significant endograft oversizing and treatment for type B dissection are key risk factors for the highly fatal complication of retrograde type A dissection following TEVAR.
Although RTAD after TEVAR is an uncommon complication, it has a high mortality rate. RTAD is significantly more frequent in patients treated for acute and chronic type B dissection, and when the endograft is significantly oversized. The proximal endograft configuration was not associated with any difference in the incidence of RTAD.
Canaud et al. (Fri,) studied this question.
