Key result
Iatrogenic dissection (OR 5.7) and preoperative CPR (OR 5.5) independently increased operative mortality, while antegrade selective cerebral perfusion reduced postoperative stroke (4.7% vs 20.1%, P=0.01).

May warrant risk stratification by etiology and resuscitation status in type A dissection; leaves open perfusion benefits pending randomized confirmation.
Cohort (n=252)
Iatrogenic dissection, preoperative cardiopulmonary resuscitation, and prolonged extracorporeal circulation are independent risk factors for operative mortality in acute type A aortic dissection surgery, while antegrade selective cerebral perfusion reduces postoperative stroke risk.
M Tan (2003) conducted a cohort in Acute type A aortic dissection (n=252). Operative risk factors and surgical techniques vs. Absence of risk factors or alternative techniques was evaluated on Operative mortality. Iatrogenic dissection (OR 5.7) and preoperative CPR (OR 5.5) independently increased operative mortality, while antegrade selective cerebral perfusion reduced postoperative stroke (4.7% vs 20.1%, P=0.01).
