Key result
Patients with acute type A dissection and malperfusion syndrome who survived initial percutaneous reperfusion and underwent delayed surgical repair had similar median survival (80.5 months) compared to uncomplicated patients undergoing immediate repair (95.9 months, P=0.45).
Why the study?
Does initial percutaneous reperfusion followed by delayed open surgical repair reduce mortality in patients with acute type A aortic dissection and malperfusion syndrome compared to immediate open repair?
Cohort (n=196)
No

Absolute Event Rate: 80.5% vs 95.9%
p-value: p=0.45
In patients with acute type A aortic dissection complicated by malperfusion syndrome, a strategy of initial percutaneous reperfusion and delayed open surgery significantly reduces mortality compared to immediate open repair.

Supports initial reperfusion and delayed repair in malperfusion syndrome; extends observational data but leaves open randomized confirmation versus immediate surgery.
Yang et al. (2016) conducted a cohort in Acute type A aortic dissection (n=196). Initial percutaneous reperfusion and delayed open surgical repair vs. Immediate open surgical repair was evaluated on Median survival (months) in the operated subgroup (p=0.45). Patients with acute type A dissection and malperfusion syndrome who survived initial percutaneous reperfusion and underwent delayed surgical repair had similar median survival (80.5 months) compared to uncomplicated patients undergoing immediate repair (95.9 months, P=0.45).
