对于不能手术切除的肝脏恶性肿瘤,经血管途径行介入治疗可获得可靠疗效。所以准确的描述肿瘤血供对肝癌的介入治疗就显得尤为重要。近年来研究表明,肝癌血供较为复杂,存在肝动脉、肝外侧支、门静脉供血及肝动脉门静脉双重供血等情况。随着介入治疗次数的增加,肝癌血供亦发生变化。肝癌血供研究直接影响对其介入治疗方式的选择和疗效。
For unresectable hepatic malignancies, transcatheter interventional therapy can achieve reliable results. Therefore, accurate description of the tumor blood supply of interventional treatment of liver cancer is particularly important. In recent years, studies have shown that the blood supply of liver cancer is more complicated, there is the hepatic artery, extrahepatic lateral branch, portal vein blood supply and hepatic artery portal vein double blood supply and so on. With the increase of interventional therapy, the blood supply of liver cancer also changes. The research of blood supply of liver cancer has a direct impact on the choice and curative effect of interventional therapy.
