Abstract:
Objective To evaluate the effect of 915 MHz microwave percutaneous coagulation of splenic artery injury in vivo experimental.Methods The manufacture model of the splenic artery injury were made and divided into two groups:group A (peripheral splenic artery injury) and group B (central type of splenic artery injury),915 MHz,2450 MHz microwave coagulation therapy and drug injections were performed under the guidance of ultrasound contrast.The hemostatic effect,operating time,total therapy time,amount of bleeding,amount of fluid infusion and histologic findings were compared.Results The treatment time of 915 MHz microwave[group A(4.65 ± 5.45),group B (9.38 ± 5.62) s] was less than those of 2450 MHz microwave[group A(86.36 ± 6.34) s,group B(127.72 ± 5.34) s] and drug injection [group A(128 ± 4.85)s,group B(182 ± 7.28)s],on the other hand,the amount of bleeding and fluid volume was less than that of rest methods.Conclusions Contrast-enhanced ultrasound guided 915 MHz microwave has significant hemostatic effect compared with the other two methods,915 MHz microwave percutaneous coagulation therapy has important significance to splenic artery injury in clinical.
