肝门静脉海绵样变性的CT特点

CT features of cavernous transformation of the portal vein

目的分析门静脉海绵样变性(CTPV)的肝脏动脉及肝脏形态学变化的影像学特点。方法13例CTPV患者,排除肝脏恶性肿瘤及肝硬化、肝脓肿等可引起肝脏动脉改变的疾病,分析其CT资料,观察肝脏动脉及肝脏形态的改变。结果13例CTPV患者中,10例(76.92%)可见肝左和(或)肝右动脉增粗,3例(23.08%)可见动脉期的一过性团片状异常强化,仅1例(7.69%)可见明显的萎缩-增生复合体。结论CTPV肝脏动脉供血增加,可出现肝脏动脉增粗,仅少数可见明显的萎缩-增生复合体。

Objective To analyze the CT features of hepatic artery and morphology changes of the liver in patients with cavernous transformation of the portal vein （CTPV）. Methods Thirteen patients of CTPV without malignant hepatic tumor or other diseases being able to cause changes of hepatic artery such as cirrhosis and hepatophyma were collected. CT data was analyzed,and the arterial and morphology changes of the liver were observed. Results Left and （or） right hepatic arteries were found dilated in 10 patients （76.92%）,and unusual flake like enhancement was found in artery phase in 3 patients （23.08%）. Atrophy-hypertrophy complex （AHC） could be found only in 1 patient （7.69%）. Conclusion Dilatation of hepatic artery manifests more hepatic artery blood supply,while obvious AHC is hardly found in CTPV.
