Abstract:

Objective

To investigate the application value of C-arm lipiodol CT in transhepatic arterial chemoembolization（TACE）for hepatocellular carcinoma transhepatic arterial chemoembolization（HCC）.

Methods

Totally 40 HCC patients diagnosed clinically underwent TACE after 64-slice CT.Digital substraction angiography（DSA）was firstly done then lipiodol was injected into hepatic arterial for diagnostic embolization during TACE.Then C-arm lipiodol CT was done after diagnostic embolization immediately.If HCC lesions were diagnosed，gelfoam particle was superselective injected into the tumor nourishing blood vessel through microcatheter.Lipioldol CT was performed in 7-14 days after TACE.Images acquired with 64-slice CT，DSA，C-arm lipiodol CT and lipiodol CT were retrospectively reviewed by 4 doctors.The number of detected lesions in each examination was counted respectively.Lipiodol CT images were used as the diagnostic reference for C-arm lipiodol CT.AFP was examined before and after TACE.

Results

64-slice CT detected 13 doubtful lesions，DSA detected 10 definite and 4 doubtful lesions，C-arm lipiodol CT detected 71 and lipiodol CT detected 67 definite lesions.The AFP value was（452.3±192.6）μg/L and（223.8±93.2）μg/L before and after TACE.Statistical difference was found（t=2.131，P=0.039）.

Conclusions

C-arm lipiodol CT can detect micro HCC lesions early in TACE，so the patients can receive early treatment.
