ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical significance of 320-slice CT hepatic artery images in patients with liver transplantation.</p><p><b>METHODS</b>A total of 58 patients underwent CT scanning by 320-slice scanner after liver transplantation. They were divided into 2 groups according to the concentration of contrast media as follows Group A (27 cases, 350 mgI/ml iopromide), Group B (31 cases, 370 mgI/ml iopromide). Contrast medium was infused at 6 ml/s, with a total dose of 50 ml. Images were generated by dynamic volume scanning and were processed by 4D digital subtraction angiography (DSA) imaging software. The time-density curve (TDC) of the hepatic artery was delineated. The time to peak, peak contrast enhancement were recorded. The physiological parameters such as body weight and height were analyzed.</p><p><b>RESULTS</b>(1) There were no differences in clinical parameters such as age, sex, height, weight, or BMI between groups. The time to peak of hepatic artery of group A and B was (19.71+/-3.11) s and (20.06+/-3.67) s, and had no significant difference. The maximum peak enhancement of hepatic artery in groups B was higher than that group A (P < 0.05). (2) 4D DSA revealed hepatic artery pseudo-aneurysm (n = 2), and hepatic artery mild stenosis (n = 13), moderate stenosis (n = 5), severe stenosis (n = 9) and occlusion (n = 1), segmental moderate and severe stenosis (n = 4), and compensatory circulation with hepatic artery severe stenosis and occlusion (n = 6). hepatoportal arteriovenous fistulas (HPAVF, n = 12), donor-recipient hepatic artery mismatch (n = 3). Hepatic arterial branch are decreased and opened in 15 cases and 8 cases.</p><p><b>CONCLUSION</b>320-slice CT hepatic artery images is safe, noninvasive, and accurate technique to evaluate hepatic arterial complications after liver transplantation.</p>
