New predictive model for microsurgical outcome of intracranial arteriovenous malformations: study protocol.

ABSTRACT:

Introduction

Although microsurgical resection is currently the first-line treatment modality for arteriovenous malformations (AVMs), microsurgery of these lesions is complicated due to the fact that they are very heterogeneous vascular anomalies. The Spetzler-Martin grading system and the supplementary grading system have demonstrated excellent performances in predicting the risk of AVM surgery. However, there are currently no predictive models based on multimodal MRI techniques. The purpose of this study is to propose a predictive model based on multimodal MRI techniques to assess the microsurgical risk of intracranial AVMs.

Methods and analysis

The study consists of 2 parts: the first part is to conduct a single-centre retrospective analysis of 201 eligible patients to cre
