摘要:Percutaneous ethanol injection therapy(PElT) has been established as an interventional method of the ablation of hepatic malignancies, especially hepatocellular carcinoma(HCC), since long. Its effects are based on cellular dehydration,toxic and coagulation necrosis and thrombosis of small venules within the tumour. The result is fibrosis of the damaged tissue, loss of function and shrinkage. Hence the "ablative" effect of absolute(95%) ethanol. The more confined ally lesion the better the ablative effect due to the high concentration of the toxic liquid. Highest effects will be achieved in encapsulated nodules which prevent diffusion of the toxic agent into surrounding normal tissue which is the case in HCC.
