Title: CT-guided percutaneous ethanol injection for hepatic metastasis
Abstract: Objective To evaluate the clinical value of CT-guided percutaneous pure ethanol injection (PEI)in hepatic metastasis.Methods Fifty three cases of metastatic tumor in liver with 87 lesions in total consisted of diameters of 18 lesions lesser than 1cm,of 56 lesions ranging from 1 cm to 3 cm,and of 13 lesions more than 3 cm but less than 5 cm.These metastatic lesions were treated with CT-guided percutaneous pure ethanol injection and undergone necrosis after one or more PEI treatment.Results These metastatic 1 esions were reexamined by CT or MR one month post-treatment of PEI.Complete necrosis rate was 100% in 18 lesions with diameter less than 1 cm.Complete necrosis rate was 87.5% in 56 lesions ranging from 1 cm to 3 cm in diameter,the residual lesions were completely undergone necrosis after second ethanol injection.Complete necrosis rate of 61.5% for 13 lesions with diameter more than 3 cm but less than 5 cm obtained complete necrosis after two or three times with PEI.Conclusion Curative effect of CT-guided percutaneous pure ethanol injection in hepatic metastasis is satisfactory especially suitable for single lesion with diameter less than 3 cm.
