This video will show the multimodal approach to a large ruptured callosal AVM in a young girl. In June 2020 she had seizure and loss of consciousness due to a massive intraventricular hemorrhage due to the rupture of an intranidal aneurysm, and later she came to our attention for this AVM, elsewhere judged inoperable. We opted for surgery after a new selective endovascular session. She was operated through a transcallosal approach with cure of the AVM and without postoperative neurological deficits. We will present the choice of selective embolization to exclude the more inaccessible part of the AVM, the use of Na++ Fluorescein as intraoperative vascular visualization, the use of Ultrasonic aspirator to remove the embolized part of the AVM and finally the use of Thulium Laser to coagulate small deep vessels. This video shows also that a small postoperative residual was found at the post-op Angiogram and how it was removed the following day, and will show how to deal with deep draining veins and how to define the proper endovascular preoperative strategy.
