Figure legends
Figure 1. Chest CTA showed severe coarctation of the aorta with severe
calcification. The constricted segment was far from the left subclavian
artery. The length of the constricted segment was about 3 cm. Two
constricted rings were seen, and no obvious collateral circulation was
formed.
Figure 2. Preoperative aortic angiography showed that the aorta was
narrowed, the degree of narrowing was about 70%, the distal end of the
narrowing was expanded, and the pressure difference between the two ends
of the narrowing was 80mmHg.
Figure 3. Postoperative angiography showed that the pressure difference
at both ends of the aortic coarctation dropped to 0 mmHg. The covered CP
stent has a good shape and a proper location.
