Patient 5.

A, Left carotid angiogram shows a pseudoaneurysm in the bifurcation (arrow).

B, After 3 fiber coils (arrowheads) were placed in the main trunk of the ECA, an 8 × 50-mm stent was deployed in the left carotid artery.

C, Reconstructive CT angiography (curved multiplanar, reformatted images) of left carotid artery 2 months later shows complete obliteration of the pseudoaneurysm. Retained fiber coils in the thrombosed ECA with metallic artifact were also found (arrows).

D and E, Contrast-enhanced axial CT scans of the head and neck 4 months later show septic thrombosis of the stent-graft with gas collection (arrow in panel D) and several brain abscesses (arrowheads in panel E).
