Enhanced computed tomography (CT) imaging. A: Preoperative CT findings show that the anastomotic pseudoaneurysm was 58.0 mm in size. The diameter of the coarctation of the aorta (CoA) is 7.5 mm (blue arrows). B: On postoperative CT, CoA expanded to 15.0 mm in size (yellow arrows). No significant endoleakages were observed in the pseudoaneurysm.

The diameter of the CoA lesion was 7.5 mm (Fig. 1). Postoperative enhanced CT imaging showed no endoleakages in the pseudoaneurysm, and the diameter of CoA had expanded from 7.5 mm preoperatively to 15.0 mm postoperatively (Fig. 1B).
Aortic pressure study and angiography. A: Under occlusion of the bypass graft, the pressure gradient across CoA was approximately 25 mmHg. B: Preoperative angiography showed blood flow from CoA and prosthetic graft to pseudoaneurysm.

The arterial pressure was 98/56 (73) mmHg and 76/54 (64) mmHg in the aorta proximal and distal to the CoA, respectively (Fig. 2).

PG improved to 0 mmHg. Post ballooning, the LSCA and old bypass graft were occluded using 3 embolisation devices (2 Vascular-plugs, 14 mm; and a RUBY-coil, 35 cm, 8 mm) to prevent type 2 endoleakage (Fig. 3).
