Reliability of hepatic artery configuration in 3D CT angiography compared with conventional angiography - special reference to living-related liver transplant donors

Abstract

Summary Although an accurate anatomical understanding of the hepatic arteries is the most and essential step in living‐related liver transplantation (LRLT), the need to reduce the burden place on the donor should be considered in imaging diagnosis. The present study examined the reliability of intravenously enhanced three‐dimensional (3D) angiography from multidetector‐row computed tomography (MDCT) in evaluating the anatomical configuration of the hepatic arteries comparing with those from conventional angiography by Seldinger method. A total of 109 patients underwent MDCT and 3D images were reconstructed on arterial phase using the volume rendering (VR) method. In the case of 3D angiography, at an infusion rate of 4 ml/s, the extrahepatic hepatic arteries were visualized successfully in all cases (the right, left and middle hepatic artery). The aberrant hepatic arteries were successfully visualized in 23 of 24 cases. The 3D angiography is a reliable method of visualizing the extrahepatic and aberrant hepatic arteries. This minimally invasive examination procedure is useful in individual operative planning and is help to increase the safety of surgery.

3D Anatomical Variations of Hepatic Vasculature and Bile Duct for Right Lateral Sector of Liver with Special Reference to Transplantation

“…Reliability of the 3D MD-CT on the anatomical evaluation of the living liver donors has been reported in several articles [12,13,[20][21][22][23]. The advantages of MD-CT are mainly faster scanning capability, improved temporal resolution, improved spatial resolution and increased effectiveness of the intravascular contrast agent.…”

“…The advantages of MD-CT are mainly faster scanning capability, improved temporal resolution, improved spatial resolution and increased effectiveness of the intravascular contrast agent. Sakai et al [12] reported that, comparing with conventional angiography, 3D CT angiography depicted the extra hepatic arteries and the aberrant arteries successfully and also depicted the intrahepatic segmental arteries with a high detection rate. These results are comparable with the other published literature [13,21].…”

“…Newly developed multi-detector computed tomography (MD-CT) images of the portal vein, the hepatic artery and the bile duct enable us to define the variations of the segmental hepatic structures accurately [12,13] and the three dimension (3D) integrated images contribute to surgical simulation in a better way.…”

“…Multi-detector row CT may not be a perfect reference standard for this purpose. However, in a growing body of studies, multi-detector row CT, with its high spatial resolution, is being recommended as a noninvasive imaging modality for hepatic vasculature mapping (12,(25)(26)(27).…”

“…The advantages of MD-CT are mainly faster capability, improved temporal resolusion, improved spatial resolusion and increased effectiveness of the intravascular contrast agent. Reliability of the 3D MD-CT on the anatomical evaluation has been reported in several articles 5,6,9,10) . However, a problem is that 3D reconstruction imaging does not protect www.intechopen.com …”
