Abstract:
Objective To study the DSA hepatoarteriography manifestations in hepatic carcinoma after endocare cryocare system (ECS)treatment for improving the comprehensive therapy of hepatic carcinoma.Methods Thirty eight male patients with primary liver cancer ( n =32) and hepatic metastasis (n=6) were enrolled in this study. Common hepatic arteriography or super-selection angiography was performed in all patients after ECS treatment in 7 days and 30-60 days.Results The foci covered with ice ball were shown as round or ovoid. Single tumor less than 5 cm was covered completely, while the shape of focus covered with more ice ball showed irregularity, mass-like and diffuse nodulss with diseminated tumor vessels and tumor stains. The shortcoming of ECS included 18 missed areas, hepatic A-V shunt and hepatic A-portal V shunt in 4, bleeding in puncture tract 5, and extravasation of contrast material in 6 cases. Delineated margin existed between the frozon area and surrounding tissues.Conclusions ①ECS is effective on liver tumor 5 cm. ③ Tendency of missed areas in huge tumor and widespread nodes accurs after ECS. ④Complication occurs easily during ECS performance near the hepatic capsule and porta hepatis. ⑤TACE would improve comprehensive therapy effect of liver cancer about7 days after cryotherapy.
