Peripheral extremity ischemia in patients presenting with a DeBakey type 1 aortic dissection is an independent predictor for mortality. We present a patient with a DeBakey type 1 aortic dissection and peripheral extremity malperfusion that underwent simultaneous aortic repair and percutaneous femorofemoral shunt with arterial sidearm. Our approach allows for immediate peripheral extremity reperfusion and subsequent objective determination of the necessity of femorofemoral bypass via perfusion pressures.
