Objective To explore the value of cryosurgery with argon-helium knife in the treatment of tumor. Methods Patients with unresectable primary hepatocellular carcinoma, retroperitoneal vascular endothelial sarcoma, left squamous cell carcinoma of the left lung, and right thyroid medullary carcinoma underwent argon-helium cryoablation guided by ultrasound. Results After 4 months, the B-ultrasonography and CT reexamination of all 4 patients were reduced by 1/3, and the clinical symptoms were obviously improved. Conclusion The cryosurgery with B-guided argon-helium cryoablation is accurate, safe, reliable, and effective. It has important value and clinical significance.
