Objective To summarize the curative effect of argon-helium cryoablation in resection of intracranial tumors. Methods and Results A total of 11 patients with primary intracranial tumors, including 7 cases of glioma and 4 cases of meningioma, were enrolled in this study. The tumor was located in left frontal lobe in 4 cases, left fronto-parietal lobe in 2 cases, left temporal lobe in 2 cases and right temporo-parietal lobe in 3 cases. Argon-helium cryoablation was used to assist intracranial tumor resection. Among 7 cases of glioma, 4 cases were totally removed and 3 cases were partially resected. Four cases of meningioma were totally removed. The average intraoperative blood loss was 80 ml, and average operation time was 80 min. Postoperative clinical symptoms were improved, and head CT or MRI showed no rebleeding. Patients were followed up for an average of 4 years, and none of them suffered from operation-related or postoperative complications such as intracranial infection, or tumor recurrence. Conclusions Argon - helium cryoablation is suitable for intracranial tumors with different diameters and in different locations. It is safe and effective, with few operation-related or postoperative complications, less rebleeding and low risk of recurrence, which is a highly efficient and relatively low?cost assistant surgical method.
