Description

Objective: We report a case of a fusiform aneurysm of vertebral artery, treated by second stent placement using stent-in-stent technique on down-the-barrel view (DBV) for a stent assisted coil embolization.<br>Case presentation: A 60-year-old woman had a fusiform aneurysm of the right vertebral artery growing up in size during 1 year follow up. Stent-assisted coil embolization using an Enterprise stent was performed. During coil embolization with the initial Enterprise stent, coil migration to the parent artery was seen on DBV. The second Enterprise stent was deployed in a stent-in-stent manner. Following deployment of the second stent, coil migration to the parent artery disappeared with preserving the vessel lumen. Complete occlusion of the aneurysm and good patency of the parent artery were seen on 3 months’ follow up angiogram.<br>Conclusion: Second stent placement using stent-in-stent technique may be effective for management of coil herniation to the parent vessel during stent-assist coil embolization for fusiform vertebral artery aneurysm.
