There was a long lesion of the whole segment III of the thoracic aorta (Figure 1).
Percutaneous transluminal angioplasty was performed with Tyshask 8 (A) and 10 mm (B).

The procedure of percutaneous transluminal angioplasty was performed with Tyshask 8 and 10 mm (Figure 2).
An inner 8Fr Amplatzer Delivery (short arrow) covered by a 10Fr Cook Outer Sheath (long arrow) was inserted into the descending aorta.

Hence, it was strengthened by an 8Fr Amplatzer Delivery inside, and the whole delivery system, including an inner 8Fr Amplatzer Delivery covered by a 10Fr Cook Outer Sheath, was successfully inserted into the descending aorta without any difficulties (Figure 3).
The first 12x59 mm cover stent at the distal of the descending thoracic aorta.

Two 12x59 mm Balloon-Expandable Covered Stents (Begraft) were completely deployed to the distal and proximal parts of the lesion at 12 and 14 atm, respectively, then a Tyshask 14 mm was used to optimize stent expansion (Figures 4 and 5).
The second 12x59 mm cover stent at the proximal of the descending thoracic aorta.

The ultimate result with the diameter of the narrowing segment returned to the normal range.

The diameter of the narrowing segment returned to the normal range (more than 90% of the normal descending aortic segment) (Figure 6).
