The Clinical Value Of DynaCT In Patient With Hepatocellular Carcinoma Underdoing Transhepatic Arterial Chemoembolization

Objective:To analyze and compare the operation time between 2D-DSA and the combination of 2D-DSA and DynaCT;Analyze the difference in detection of occult lesions and Identification and characterization of arterial supply to a tumor though comparing 2D-DSA image with enhanced DynaCT image in TACE; Analyze the difference between the iodized oil deposition image of X-ray and the iodized oil deposition image of DynaCT to evaluate the embolism efficacy. To evaluate the clinical value of DynaCT scanning in performing TACE for hepatocellular carcinoma.Methods:From March 2013-March 2015,60 patients with hepatocellular carcinoma who were treated with TACE in Shandong Cancer Hospital were randomly divided into two groups,30 patients were performed with combination of 2D-DSA and DynaCT(Group Ⅰ),the other 30 patients were simply performed with 2D-DSA.After the embolization,all patients were performed with X-ray and unenhanced DynaCT.To analyze and compare the operation time between 2D-DSA and the combination of 2D-DSA and DynaCT;Analyze the difference in detection of occult lesions and Identification and characterization of arterial supply to a tumor though comparing 2D-DSA image with enhanced DynaCT image in TACE; Analyze the difference between the iodized oil deposition image of X-ray and the iodized oil deposition image of DynaCT to evaluate the embolism efficacy.Results:1.The operation time of both groups uses T-test.The operation time of both groups has no significant difference(t=,p<0.05).2.1n Group I,the total number of tumors which were found by 2D-DS A is 69,while,in Group II,he total number of tumors which were found by DynaCT is 85.The differences between the two groups was statistical significant(x2=4.6, P<0.05).3.In Group 1,8 of 30 patients’tumor blood vessels were showed unclear in the 2D-DSA,but including 6 patients blood vessels can be clearly displayed in the DynaCT(x2=6.53, P<0.05).4.In Group 1,8 patients’blood-supplying artery of tumor were not clearly displayed in 2D-DSA.Then the 8 patients were performed with DynaCT,and 6 of them were clearly displayed.The differences between the result was statistical significant(x2=4.6, P<0.05).5.In all 69 tumors(which were found by 2D-DSA),there are 40 Iodized oil deposition uniformity of tumor and 29 iodized oil deposition uneven tumor which were found in DynaCT,while,there are 60 Iodized oil deposition uniformity of tumor and 9 iodized oil deposition uneven tumor which were found in 2D-DSA.The difference was a significant difference.6.In performing TACE for hepatocellular carcinoma, DynaCT is a useful auxiliary tool for 2D-DSA.Without increasing surgical time,DynaCT can not only increases the detection rate of the small liver cancer,but also has obvious advantage of identify arterial supplying the tumors.At the same time,for instant assessing the iodized oil uptake after the procedures,DynaCT is a useful and convenient tool.In short,DynaCT has important clinical value in TACE for hepatocellular carcinoma.
