Abstract
Background
This report described the surgical resection of a challenging medial parietal lobe arteriovenous malformation (AVM) using the hybrid operation theater with a multimodal imaging-guided technology.
Method
A 29-year-old male was admitted to treat a ruptured medial parietal AVM. The deep and diffusive compartment of the nidus was embolized before resection. Preoperatively and intraoperatively, mixed reality technology with multimodality imaging was utilized for surgical planning and navigation. The nidus was totally resected and confirmed by intraoperative angiography. The patient recovered without sequella.
Conclusion
We hope this report provides new insights into applying multimodal imaging technology-guided hybrid operation for brain AVM.

Key points
1. Surgical resection of medial parietal AVMs can be challenging due to their location and proximity to eloquent structures.
2. The distal cortical branches of the ACA and PCA are the main suppliers of medial parietal AVMs.
3. The drainage route for medial parietal AVMs can be either superficial or deep, ascending towards the SSS and/or descending towards the VoG.
4. Medial parietal AVMs invading the paracentral lobule are considered eloquent, as they are associated with the somatosensory cortex responsible for leg sensation.
5. The hybrid operation theater can ensure safe, comprehensive multimodality evaluation and treatment of brain AVM, offering the opportunity for favorable curative treatment.
6. The mixed reality technology can be utilized to understand surgical anatomy and plan thoroughly.
7. Embolization through the PCA can be used to occlude the most diffusive and deepest compartment of the medial parietal AVM.
8. Temporary clipping of the primary suppliers to the nidus is the key for early proximal control during surgery.
9. Careful dissection and inspection are crucial to prevent contralateral ACA and PCA injury.
10. The drainage veins should only be transected after most of the nidus was circumstantially devascularized.
