Two cases of coarctation of the abdominal aorta are reported to illustrate the salient diagnostic points and the improvement following surgery. Coarctation of the low thoracic or abdominal aorta must be considered strongly in young female patients who have upper extremity hypertension, strong upper abdominal aortic pulse which disappears distally or no aortic pulse in the abdomen and a murmur or bruit in the epigastrium. Chest roentgenograms show lack of findings of coarctation of the aorta at the arch level, but associated rib notching of the 10th to 12th ribs. Aortography is essential in making the diagnosis and as a guide to the therapeutic approach. Vascular surgery will alleviate the condition.
