Predictive score for complete occlusion of intracranial aneurysms treated by flow-diverter stents using machine learning.

abstract：INTRODUCTION:Transarterial embolization with Onyx is a relatively safe and increasingly common method of treating cranial dural arteriovenous fistulas (DAVF) and arteriovenous malformations (AVM). Cranial neuropathy resulting from this procedure has been reported. CASE REPORTS:Three case histories are presented in two...
