Abstract
Background
This report described the surgical nuance of a challenging deep-seated corpus callosum arteriovenous malformation (AVM) using a novel robotic digital microscope.
Method
A 64-year-old male was admitted to treat a ruptured corpus callosum AVM. In order to facilitate surgical manipulation under the robotic digital microscope, a gravity-assisted supine position was utilized. Intraoperatively, identifying and preserving the transit and bystander artery is important while skeletonizing the anterior cerebral artery. The nidus was totally resected and the patient was discharged without sequella.
Conclusion
It is feasible to perform complicated AVM resection under the robotic digital microscope with a rigorous surgical plan.

Key points
1. The surgical removal of a challenging deep-seated corpus callosum AVM should be well-planned perioperatively.
2. The preoperative instruments setup aims to achieve the optimal ergonomics of the robotic digital microscope. .
3. Deliberate practice is an effective method for improving the performance of manipulating the robotic digital microscope .
4. The gravity-assisted supine position is beneficial to achieve brain autoretratcion.
5. The neuronavigation system is essential to determine the optimal surgical trajectory without violating the frontal bridging veins.
6. The lock-on-target function can help the camera return to saved targets efficiently when moving around the robotic digital microscope.
7. Identifying and preserving the transit and bystander artery is important while dissecting the AVM nidus.
8. It is critical to secure the feeders of the AVM nidus before transecting the drainage veins.
9. The ICGVA helps confirm the patency of ACA, its major branches, and the residue nidus.
10. It is feasible to perform complicated AVM resection under the robotic digital microscope with a rigorous surgical plan.
