Clinical application of ultrasound-guided microwave coagulation on treatment of liver carcinoma

Objective To evaluate the effect and clinical value of ultrasonography-guided microwave coagulation on treatment of hepatic carcinoma.Methods Fifty nodes in 33 patients with liver cancer were treated with microwave coagulation under the ultrasound with 40～80 W emission for 150～1 800 s according to size of tumors and spread of vessels.Results After a month, 96% (48/50) nodes were not enhanced on contrast CT, the AFP level recovered to normal in 15 among 21 cases.The intratumoral blood flow disappeared in 95%(42/44) node. After four months, the tumors disappeared in 4 cases. Conclusions Ultrasonography-guided microwave coagulation on treatment of liver cancer is simple, safe and effective.
