Predictors of Dumfarth et al for Postoperative Stroke After Emergent Surgery for Acute Type A Aortic Dissection

Patient selection: emergency surgery for type A aortic dissection

Independent predictors of postoperative stroke:

(1) bovine aortic arch (OR 2.3)

(2) preoperative cardiopulmonary resuscitation (OR 6.5)

(3) preoperative malperfusion (OR 2.5; cerebral, cardiac, visceral, limb)

In addition, impaired perfusion of the right carotid artery was a risk factor with OR 2.2 but p value 0.064.

The insult causing the stroke could have occurred prior to the start of surgery.

A postoperative stroke is associated with morbidity and length of stay but not mid-term survival.

Multiorgan failure was the primary cause of in-hospital mortality (OR 14.5).
