Observation Of Therapeutic Effect After Chemoembolization And Blood Supply In Liver Metastases

Objective:To evaluat DSA feature ,the value,efficacy and side effect, survival time of microcathereter superselective catherization in interventional treatment on liver metastases.Methods:60 cases with liver metastases were studied and were arterial cannulated through common femoral artery by seldinger technique,undergoing truncus coeliacus artery by 5 french cather. The concentration of the contrast medium was 300gI/ml and was injected at the rate of 4ml/s,total volume (15~25ml). If the artery was lack, second radiography was given through superselective hepatic artery. On the base of DSA feature of liver metastases, All the patients were divided into two groups: superselective-catherization group and nonsuperselective-catherization group. There were 30 patients in every group respectively. Microcather was used in the former to "embed"the tumor vessel and "siphonal"technique was used in the later .Compared the changes of the two groups in volume ,the deposit of iodized oil in liver matastases after treating one month and the changes of ALT,ALB,TBIL in blood. The efficacy and side effect were compared in two groups.The survival time and DSA feature of using microcather were also analyzed.Results:8 cases short of artery were showed more artery(2 cases were abundant artery and 6cases were under-rich artery )after the superselective hepatic artery radiography. The DSA feature and efficacy of superselective-catherization group was better than that of nonsuperselective-catherization group, the side effect was mild and the survival time was prolonged for the former .Conclusion:Microcathereter superselective catherization to treating liver metastases has better efficacy,artery radiography , lighter side effect and can prolong the survival time.
