Abstract:
Background: CT scan of hepatic carcinoma after transarterial embolization with Lipiodol (LP-TAE) will be influenced. A comparative study was made between CT scan and hepatoarteriography in hepatic carcinomas fully filled with Lipiodol after TAE for the purpose of demonstrating the difference. Materials and Methods: 20 cases of hepatic carcinoma fully filled with Lipiodol after TAE 1 to 8 months, confirmed by CT scans. Hepatoarteriography were then done 1 to 14 days afterwards. The demonstration of the original and new foci were thus be compared respec- tively by these methods. Results: The original tumor lesions were all stable on CT scans and new tumor lesions were found in 5 cases. Three features were found in arteriographies of the original tumor lesions: (1) stable, no obvious tumor vessels and stain; (2) tumor vessels and stains confined within the LP accumulated areas; (3) largely increased lesions exceeding the LP accumulated areas; (3)largely increased lesions exceeding the LP accumulated areas. Also other three features were found in new tumor lesion: (1) multiple intrahepatic daughter nodules; (2)small arterioportal shunts; (3) new masses. Conclusion: (1) Although good results had been archieved, but the lesions were not stabe in many of them. Long interval follow-up and TAE were not suitable. (2) Stage-Ⅱ surgical resection should be taken cautiously. (3) New techniques of CT scan and superselective he- patic arteriography with high flow rate should be adopted to improve the accuracy rate of de- monstrating tumor lesion.
