Abstract
Five patients with ruptured vertebrobasilar dissecting aneurysms, to which parent artery occlusion cannot be applied, were treated by using Enterprise VRD. The location of the dissecting aneurysms was the vertebral artery in three patients and basilar artery in two. In all patients, Enterprise VRD was successfully deployed in the dissecting segment, and the coils were inserted in the aneurysmal dilatation by semi-jailing technique. Ischemic complication occurred in two patients and rebleeding occurred in one patient four months after the treatment. Favorable outcomes were obtained in four of the five patients. Enterprise VRD provides easy access to the lesion, is less stressful to the parent artery in the deployment, is conformable to the tortuous parent artery, and is suitable for the semi-jailing technique.
Stent-assisted coil embolization using Enterprise VRD can be a feasible and effective treatment in selected patients with ruptured vertebrobasilar dissecting aneurysms not suitable for parent artery occlusion.
