A cardiac CT scan was further performed, and a 3 mm coarctated descending aorta (Figure 1A, arrow), with over eight collateral vessels between the proximal and radial coarctated tissue (Figure 1B) was revealed.

An aneurysmal clip (Figure 2, arrow) was successfully applied, followed by balloon angioplasty and endovascular stent implantation in the coarctated site of the descending aorta (Figure 3).
Coarctation intervention with the guidance of digital subtraction angiography: (A) The coarctated descending aorta was confirmed by the poor perfusion of the iodine contrast medium to the distal segment; (B) inserted endovascular stent; (C) balloon dilatation and endovascular stent implantation in the constricted descending aorta; (D) a free flow of the perfused contrast medium to the distal segment just after the operation.
