肝癌的门静脉血供研究及其栓塞治疗

为了证实肝癌门静脉栓塞治疗的必要性及可行性，对１７８个肝癌结节进行血管铸型、脉冲多普勒及碘油介入的多层次研究。在血管铸型的研究中，发现７５．６％（３４／４５）的肝癌结节中有门静脉分支的存在，在少数直径小于３ｃｍ的肿瘤结节中仅有门静脉分支进入（７／３５）。

Portal vein supply and emboltzation therapy for hepa-tocellular carcinoma

o prove the necessity and feasibility of portal veinembolization for the treatment of hepatocellular carcincrma (HCC) , We observed the tumor vascularity and por-tal vein supply by vascular casting, Doppler pulse sonography and iodized oil embolization in 178 HCC noduls.Portal vascularity was found in 75. 6% of noduls (34/45 ). In few neduls , which were smaller than 3cm in di-ameter, portal branches existed only without hepaticartery branches (7/35). Tumor portal blfor supply wasmeasured in 54. 1% of noduls (59/109) by usingbopplar sonography. Portal tumor branch embolizationwas performedin 24 of patients with unreseatable HCC ,all tumor noduls being filled with iodized oil. The com-bined portal vein and hepatic artery embolization wasmore effective than hepatic artery embolization in thecontrol of the disease (P<0. 01).
