Figure 14 (A-F): A case of nasoethmoidal carcinoma who had intraoperative injury to the left internal carotid artery during endoscopic surgery. (A) DSA, (B) VR image of left ICA shows a pseudoaneurysm (white arrow) arising from the cavernous portion. (C) Right ICA, (D) vertebral angiogram shows poor cross circulation across the circle of Willis during BTO. In view of torrential bleeding and failed attempt to deploy a covered stent, the left ICA was occluded (E) using coils (arrowhead) to prevent exsanguination. (F) Plain CT brain done after 24 hours shows fully evolved cerebral infarct (dotted arrow)
