Answer C) Postductal coarctation of the aorta
-
No pulse in the femoral artery, increased blood pressure in the arteries of the upper extremity, enlarged intercostal veins, and numbness and tingling in both feet are clinical symptoms indicative of postductal coarctation of the aorta.
-
Because of the constriction of the aorta, the blood supply to the lower extremity is compromised.
