Treating lower extremity malperfusion syndrome in acute type A aortic dissection with endovascular revascularization followed by delayed aortic repair

Summary of the study showing in-hospital mortality among all acute type A aortic dissection patients was significantly higher in the lower extremity malperfusion syndrome group versus no malperfusion syndrome group (31% [8 out of 26] vs 6.3% [32 out of 512]; P = .0003). Lower extremity malperfusion syndrome was defined as necrosis of the tissue of lower extremity and related organ failure.
