Learning curve and embolisation strategy in single-stage surgery combined embolisation and microsurgery for brain arteriovenous malformations: results from a nationwide multicentre prospective registry study.

ABSTRACT:

Objective

Single-stage surgery combining embolisation and microsurgery has been increasingly used as a stand-alone procedure to cure complex AVMs. This study aimed to investigate the learning curve and embolisation strategy for single-stage surgery for AVMs.

Methods

This prospective cohort study used data from the nationwide Multimodality Treatment for Brain Arteriovenous Malformations (MATCH) registry in China, conducted between August 2011 and December 2023. A total of 213 complex AVMs were divided into two groups. Group 1 included the first 25 patients. The 188 cases in group 2 included patients numbered 26-213. A case-crossover design was employed to evaluate the influence of complications, unfavourable outcomes and worsening modified Rankin Scale (mRS) score. Cumulative
