Active limb-protection in type A aortic dissection complicated by lower-extremity malperfusion

Lower extremity ischemia in acute type A aortic dissection is associated with severe complications, including amputation, acute kidney injury, and increased mortality. Timely restoration of blood flow is critical to balance the risks of delayed extremity reperfusion against those of postponed central aortic repair. We present a multidisciplinary approach involving early extremity reperfusion without delaying central aortic repair, thereby minimizing ischemia-reperfusion injury while ensuring definitive aortic management.
