A computed tomography (CT) scan revealed a 3 x 3 cm sized well-enhanced CCA pseudoaneurysm (Figure 1(a)). An angiogram showed a pseudoaneurysm just at the level of the bifurcation of the right CCA (Figure 1(b)).
Intraoperative fluoroscopic image: (a) the Jostent was deployed at the right common carotid artery (black arrow). (b) Some extravasation of contrast material was noted at the pseudoaneurysm sac after stent deployment (black arrow). (c) The right external carotid artery was trapped by fibered coil (black arrow), and another Jostent (white arrow) was deployed in the right common carotid artery. (d) No contrast material was observed within the pseudoaneurysm after stent graft placement.

After reinsertion of the stent, an angiogram showed that there was no longer contrast material within the pseudoaneurysm sac (Figure 2).

((a) and (b)) Contrast-enhanced CT angiograms demonstrating a 2.5 x 3.4 cm sized thrombosed pseudoaneurysm (arrow) in the right common carotid artery.

A CT scan revealed a 2.5 x 3.4 cm sized well-enhanced CCA pseudoaneurysm (Figure 3).
Intraoperative fluoroscopic image: (a) a right carotid angiogram demonstrating a pseudoaneurysm arising from the proximal common carotid artery. ((b) and (c)) The Jostent (black arrow) was deployed at the center of the fistula tract, and full dilatation was performed (white arrow). (d) The angiogram demonstrated a lack of contrast filling of the pseudoaneurysm after stent graft placement.

After placement of the stent, a carotid artery angiogram showed no blood flow to the pseudoaneurysm (Figure 4).
