Computed tomography (CT) angiography of the head and neck was then performed, revealing a 1.2 x 2.0 cm pseudoaneurysm with a small amount of surrounding thrombus within the distal left cervical internal carotid artery just proximal to the petrous portion (Figure 1).
Additional angiography; residual stenosis is seen proximal to the pseudoaneurysm.

A short segment of high grade stenosis (80%) was also revealed in the postbulbar region of the proximal left internal carotid artery (Figure 2).
Poststenting percutaneous transluminal angiography; stent graft placement is seen with angiography.

PA, but there were still the tight stenosis and 90-degree bend of the graft anastomosis of the endarterectomy site. For the residual stenosis, a 7 x 10 stent (Nitinol Acculink) was successfully deployed and expanded using a 5 Balloon to 6 Atmospheres (Figure 3). After full expansion was noted, the balloon was withdrawn, and completion angiography was performed confirming complete obliteration of the PA (Figure 4). Patient recovered with no postoperative neurological symptoms and had no complications upon 3-year followup.
Postintervention angiography; pseudoaneurysm is successfully obliterated and residual stenosis has been treated.
