Acute abdominal aortic dissection: Insight from the International Registry of Acute Aortic Dissection (IRAD)

IAAAD is a condition that may present differently compared with classic type B aortic dissections. IAAAD patients treated with surgical or endovascular procedures had a lower unadjusted in-hospital and long-term mortality rate compared with medically managed patients. On the basis of the present natural history report, continued surveillance appears mandatory. To improve the life expectancy of patients with IAAAD, aggressive surgical or endovascular management seems justified.
