Aortic coarctation


Bilateral inferior rib notching is indicating that the coarctation is distal to the origin of both subclavian arteries and bilateral collaterals are formed between internal thoracic(mammary) artery, anterior intercostal artery, posterior intercostal artery and descending aorta.

Contrast enhanced CT scan confirms the subtle x-ray findings that were consistent with aortic coarctation.
