CT features of cavernous transformation of the portal vein / 中国医学影像技术

ABSTRACT

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.
