晚期肝癌供血动脉的X线解剖及其临床意义

Radio-anatomy of the nourish artery in hepatic cancer and its clinicalsignificance

通过对２４０例晚期肝癌的选择性血管造影分析，将其肝动脉的Ｘ线解剖分为规则性供血占７５％（１８０例）和变异性供血占２５％（６０例）。其中肝癌的寄生性动脉供血占６．３％（１５例）。后者又分为四个亚型：Ⅰ、膈下动脉供血型，占２．９％（７列）；Ⅱ、网膜动脉供血型，占１．６％（４例）；Ⅲ、结肠中动脉供血型，占１．２％（３例）；Ⅳ、肾动脉供血型，占０．４％（１例）。本文对肝癌变异性、寄生性供血的临床意义进行了讨论。

he blood supply of the nourish arteries was on 240 cases of late hepatic cancer patients byangiography. 25%(60 cases)of that were from variant type of hepatic arteries;of which,15 caseswere identified as parasitic arterial blood supply. Four subtypes of the parasitic were divided as :I.blood supply from the inferior phrenic artery( 7 cases),Ⅱ.blood supply from the gastroepi-ploic artery(4 cases),Ⅲ.blood supply from the middle colic artery(3 cases),Ⅳ; blood supplyfrom the renal artery(l cases).The mechanism and signiflcance for nourish arterial parasitizationin hepatic cancer patients were discussed.
