Abstract:Objective:To evaluate the value of color Doppler flow imaging (CDFI) in detecting the blood supply of primary hepatic carcinoma in comparison with DSA.
Methods:Fiftytwo hepatic carcinoma patients with 64 tumors were studied. All patients were examined by CDFI within three days before transarterial chemotherapy embolization (TACE) treatment. The artery supply of 64 tumors was graded into four degrees: 0,Ⅰ,Ⅱand Ⅲ. The diameter, peak systolic velocity (PS), and resist index (RI) of proper hepatic artery were measured. Meanwhile the blood flow volume of portal vein and proper hepatic arteria was calculated. In the procedure of TACE, blood supply of tumors was graded into three degrees: grade1, 2, and 3 by DSA. Thirty tumors in 30 patients were followed up with CDFI within 7 days after TACE. The changes of the gradations of blood supply and hemodynamics of proper hepatic arteria, portal flow and tumors were analyzed by CDFI.
Results:(1)The gradation of CDFI in the blood supply of HCC had positive correlation rank compared to that of DSA (rs＝0.644，P<0.01). Grade 0,GradeⅠ and Ⅱ,Grade Ⅲ in CDFI closely corresponded to Grade 1,Grade 2,Grade 3 in DSA respectively. (2)After TACE, the gradations of the blood supplies decreased. The diameters of proper hepatic arteries became slightly narrow and their blood flow volumes decreased. But portal flow volumes increased.
Conclusions:The gradation in impulse blood of HCC with CDFI has positive correlation rank, Grade 0,GradeⅠ and Ⅱ,Grade Ⅲ in CDFI correspond to Grade 1,Grade 2,Grade 3 in DSA respectively. and CDFI can reflect indirectly the changes of hemodynamics before and after TACE.
