Abstract:
Objective To research the angiographic manifestations of rabbit implanted VX_2 liver carcinoma.Methods 34 New Zealand big white rabbit were implanted VX_2 tumor pieces under orthophoria into liver left middle segment.Angiography of coeliac artery-hepatic artery catheterization via right femoral artery was performed at the third week after inoculation.Results The tumor blood vessel and tumor stain in 6 rabbit could be not showed clearly by digital cinematography mode but which could be showed in 28 rabbit by digital subtraction mode.The tumor angiographic signs included:dilating growth of tumor,the feeding arteria surrounding the tumor surface were resemblance to the clenched fist,embraced globosity and wreath in form;many slender vessels from feeding arteria appeared as small bud form,root form and filose form pushed forward to the center from the surface of tumor.The tumor vascular density in periphery was higher than that in center and formed circular or oval tumor stain which more denser at periphery than center.The tumor node stain was complete with definite margin when tumor size was large or equal to 1 cm in diameter,and the tumor stain appeared as clump with indefinit margin.Conclusion There are abundant vascularity for rabbit implanted liver VX_2 tumor,and more abundant at periphery part than center part, coeliac artery catheterization angiography can show the typical manifestations of tumor clearly.
