Imaging findings
A 37-year-old female with blood pressure discrepancies. Imaging showed complete aortic coarctation with significant collateralization via dilated internal mammary and intercostal arteries. Additionally, the intercostal arteries were markedly dilated, forming multiple aneurysms.
Key takeaways
Long-standing, severe aortic coarctation can result in complete aortic interruption. A rare but recognized complication is the development of aneurysms of the intercostal arteries due to the high-flow collateral circulation required to bypass the obstruction.
