FIG 2. Endovascular treatment of HNC-related CBS by use of the self-expanding, covered Wallgraft stent.
A, Initial angiogram reveals a stump (arrow) at the proximal external carotid artery.
B, Microcatheter injection of the stump during endovascular exploration confirms a pseudoaneurysm as the source of hemorrhage.
C, An 8 x 30 mm Wallgraft stent is positioned within the common carotid artery and ICA junction, bridging the external carotid artery origin.
D, After deploying the stent, angiography shows exclusion of the pseudoaneurysm and normal caliber of the parent, stented artery.
E, Digital subtraction angiogram mask is shown for detail.
F, Photograph of the Wallgraft stent is shown for detail.
