Why the study?
Conventional surgery for acute type A aortic dissection can leave a chronically dissected distal aorta with risk for dilatation, propagation, and rupture, requiring serial imaging.
Highlights the importance of serial imaging surveillance in ATAAD survivors to detect early and late postoperative complications.
Distal aortic complications warrant ongoing surveillance after conventional ATAAD repair in DeBakey type I; leaves open optimal long-term strategies.
Acute type A aortic dissection (ATAAD) is a life-threatening condition that requires emergency surgery to avert fatal outcome. Conventional surgical procedures comprise excision of the entry tear and replacement of the proximal aorta with a synthetic vascular graft. In patients with DeBakey type I dissection, this approach leaves a chronically dissected distal aorta, putting them at risk for progressive dilatation, dissection propagation and aortic rupture. Therefore, ATAAD survivors should undergo serial imaging for evaluation of the aortic valve, proximal and distal anastomoses, and the aortic segments beyond the distal anastomosis. The current narrative review aims to describe potential complications in the early and late phases after ATAAD surgery, with focus on their specific imaging findings.
