Left temporal lobe AVM and preoperative magnetic resonance (A,B) demonstrate the location and size of AVM; Preoperative DSA (C–F) shows feeding artery and draining vein of AVM; Preoperative planning (G) indicates the position relationship between malformations and functional configuration (shown by arrow); (H) displays an intra-operative screenshot after the exposure of AVM; (I) demonstrates that FLOW800 software could automatically rebuild color visual image, intuitively displaying feeding artery of malformations (shown by arrow); Postoperative DSA (J–L) illustrate the total resection of AVMs.
