Cryoablation of Brain Neoplasm

The procedure begins with standard surgical exposure of the tumor, followed by a biopsy. Next, one or more cryoprobes will be positioned directly into the tumor for ablation. Once positioned, the cryoablation process will commence. A maximum of 2x10 minutes cryoablation cycles will be established followed by active thawing. Following ablation, resection of the tumor will be performed, after which patients will receive standard treatment and follow-up care. Ice formation around the cryoprobes will be monitored using intraoperative ultrasound to optimize the ablation process.
