Persistent malperfusion after central aortic repair in acute type I aortic dissections.

One-third of patients with acute type I aortic dissections had associated noncardiac ischemia, prompting a vascular surgery consultation. Limb and mesenteric ischemia most often resolved after the proximal aortic repair and did not require further intervention. No vascular interventions were performed in patients with stroke. Although the presence of acute ischemia at presentation did not increase hospital or 5-year mortality rates, persistent ischemia after central aortic repair seems to be a marker for increased hospital mortality after type I dissections.
