Augmented reality and 3D modeling for preoperative planning in microsurgical resection of brain arteriovenous malformations: A proof-of-concept study.

ABSTRACT:

Background

Brain arteriovenous malformations (AVMs) present significant surgical challenges due to their complex angioarchitecture. This study evaluates the clinical application of augmented reality (AR) and 3D modeling for preoperative planning in AVM microsurgery.

Methods

A prospective series of 20 patients with Spetzler-Martin grade II-IV AVMs underwent preoperative 3D planning using computed tomography/magnetic resonance imaging segmentation (Inobitec DICOM Viewer Pro), AR navigation (Microsoft HoloLens 2 with Medgital software), and QR-code registration. Technical parameters including target registration error (TRE), preoperative preparation time, and intraoperative outcomes were analyzed.

Results

Complete AVM resection was achieved in all cases (100%). The AR sy
