Figure 3. A 57-year-old man with inoperable nasopharyngeal carcinoma treated with radical neck dissection and radiation therapy presented with massive oral bleeding.(a) The right common carotid arteriogram shows a pseudoaneurysm formation and contrast leakage into pharynx and oral cavity near the carotid bulb. (b) Immediate angiography after stent placement and coil embolisation revealed a small contrast leakage out of the distal portion of the covered stent due to luminal diameter discrepancy between the proximal internal carotid artery (ICA) and the covered stent caused by the transitional lumen size of the carotid bulb. ) (c) Final angiography shows no further leakage of the contrast agent after deployment of another self-expanding stent crossing the distal end of the covered stent. The patient became stable immediately after procedure.
