Ipsilateral mydriasis (IM) is usually not acute. However, the acute occurrence of unilateral dilated pupil may result in acute ischemic stroke. Herein, we present 3 patients with IM, lateral eye deviation, ptosis, and contralateral hemiparesis due to isolated occlusion of the pre-communicating segment of the posterior cerebral artery with preservation of the posterior communicating artery, which was successfully treated by emergent mechanical thrombectomy. In a 3-month follow-up, all patients were independent without any neurological deficits.

The widely accepted option for treating traumatic direct carotid-cavernous fistula (dCCF) has been endovascular treatment using detachable balloons, coils, or embolic agents. Covered stent deployment has been applied by a few operators and has shown promising results. This is a retrospective study on patients with dCCF treated by an endovascular approach using BeGraft, a covered stent. In 4 cases, this device was successfully deployed without any complications. Immediate complete occlusion was achieved in 3 patients (75%) after deployment of the covered stents. One patient required transvenous coiling for occlusion of the remaining endoleak. Follow-up imaging demonstrated 100% fistula occlusion with complete internal carotid artery patency. No early or late complications occurred following treatment. In conclusion, the BeGraft-covered stent could be a promising safe and effective alternative option for the endovascular treatment of dCCF.
