Abstract
|
|
|
We retrogradely analized the meannings of computed tomography during arterial portography (CTAP) compared with conventionally contrast enhanced computed tomography (conventional contrast CT) taken in 100 cases of hepatocellular carcinoma. We
could
find
57.8% additional borderline lesions with CTAP in number of patients and 92.5% in numbers of masses. Protal vein invasion which was not demonstrated by conventional contrast CT could be detected by CTAP in 10 cases. In diagnosis of unllatral or
bilateral
lobe involvement for determinantion of treatment planning. CTAP could prevent 35.5% of mis-underdiagnosis of unilateral lobe involvement by demonstrating the nodule and/or portal vein invasion of controlateral lobe.
In conclusion, CTAP is very useful in detection of hidden borderline lesion, portal vein invasion, and recognition of portal venous flow nature in preserved portion of liver. Therefore CTAP is considered essential in pretieatment evaluation of
hepatocellular carcinoma for determination of proper treatment principles.
