A 44-year-old woman presented to our institution for evaluation of an expanding aortic saccular pseudoaneurysm. She had a history of an end-end repair of coarctation of the aorta at 4 years of age. At 29 years of age, she received a diagnosis of a pseudoaneurysm measuring 10 mm at the site of the previous repair. Since that time, the pseudoaneurysm had doubled in size. She also had a history of hypertension and had been treated with atenolol. At time of our evaluation, computed tomography angiography was performed, demonstrating mild narrowing of the aorta just distal to the origin of the left subclavian artery with a minimal diameter of 16 mm (Fig. 1). The pseudoaneurysm measured 21  17  20 mm. Due to the location of the pseudoaneurysm just distal to the origin of the left subclavian artery, the vascular surgery team translocated the left subclavian artery to the left carotid artery. Two months later, with approval from the U.S. Food and Drug Administration for compassionate use, she underwent placement of a 20-mm  3.4-cm covered stent (Cheatham-Platinum [CP] stent, NuMED, Hopkinton, New York) to dilate the coarctation and simultaneously cover the saccular pseudoaneurysm. The stent was pre-mounted on a 20mm balloon-in-balloon (BIB) catheter. Postprocedure DynaCT rotational angiography (Siemens, Erlangen, Germany) demonstrated a

7-mm residual neck not covered by the stent (Fig. 2). The patient returned for additional placement of 2 CP stents (3.4 and 2.8 cm) placed over a 20-mm BIB catheter covering the orifice of the pseudoaneurysm. Post-procedure, there was no evidence of residual aneurysm filling or dissection on DynaCT imaging, and

the patient tolerated the procedure well (Fig. 3). Followup 12 months later revealed an excellent result with no residual pseudoaneurysm and no residual gradient.

Figure 2. Residual Pseudoaneurysm After Initial Stent Placement DynaCT rotational angiography with 3-dimensional reconstruction was performed after initial covered stent placement. The residual pseudoaneurysm is noted (*), filling with contrast despite the stent. Alternate imaging planes demonstrated a 7-mm residual neck not covered by the stent. The transposed left subclavian artery is seen arising from the left carotid artery, with the stump of the original left subclavian origin also filling with contrast.

Figure 3. Successful Result After Additional Stent Placement DynaCT rotational angiography with 3-dimensional reconstruction was performed after placement of 2 additional covered stents. No residual pseudoaneurysm filling is seen. The transposed left subclavian artery can be seen arising from the left carotid artery (SC), whereas the left subclavian stump has been covered by the proximal stent.
