Abstract:
Objective To evaluate the hemostasis effect of 915 MHz microwave in the hepatic artery and portal vein injury in vivo dog liver.Methods After manufactured model of the hepatic artery and portal vein injury,915MHz microwave percutaneous coagulation therapy and drug injections were performed under the guidance of contrast-enhanced ultrasound (CEUS),the hemostatic effect,amount of bleeding and histologic findings were compared between the two groups.Results 915 MHz microwave coagulation had better hemostatic effect than drug injection,the amount of bleeding was significantly less than the injection method,and the pathological results showed that the vessel wall necrosis and surrounding tissue coagulation were more obvious than the injection.Conclusions CEUS guided 915 MHz microwave has a significant role in hemostasis,so the 915 MHz microwave percutaneous coagulation therapy of the hepatic artery and portal vein injury in vivo dog liver has important clinical auxiliary significance.
