Whether total arch replacement improves outcomes in acute type A aortic dissection remains uncertain; leaves open need for prospective trials.
Systematic Review
Does total arch replacement improve outcomes in patients with acute type A aortic dissection compared to hemiarch replacement?
p-value: p=<0.05
Total arch replacement for acute type A aortic dissection may improve false lumen thrombosis compared to hemiarch replacement, though early mortality risks vary and long-term freedom from reoperation appears similar.
Li et al. (2014) conducted a systematic review in Acute type A aortic dissection. Total arch replacement vs. Hemiarch replacement was evaluated on Operative mortality, freedom from reoperation, and false lumen thrombosis (p=<0.05). Total arch replacement for acute type A aortic dissection achieved higher rates of complete false lumen thrombosis in the proximal descending aorta compared with hemiarch replacement (P<0.05).
