Hepatic Arterial Anatomy In Transplantation Participators: Evaluation With Multiple Detector-row Spiral CT Angiography (MSCTA)

IntroductionLiver transplantation is a successful therapeutic option for patients with chronic liver disease and liver failure in that 1 — year survival is greater than 80% and 5 - year survival is 65% - 78%. To achieve successful liver transplantation , it is essential to evaluate the participators before operation, especially hepatic arterial anatomy. Imaging methods used for evaluating hepatic arterial anatomy include digital subtraction angiography(DSA) , magnetic resonance an-giography(MRA) , computed tomography angiography(CTA) and color Doppler sonography(CDS) , they have different characteristic. In 1995, it was firstly reported by Winter et al. that CTA was as accurate as DSA in the assessment of the arterial blood supply to the liver in a safer, more convenient, substantial cost - saving procedure. At present, the development of CT technology is supplying the better external condition for this kind of study.Materials and Methods1. Dual phasic scanning of MSCT(GE, Light Speed16) in 31 patients of the transplantation were performed before operation.2. All of the primary scanning data was sent to the Workstation, and the post - processing methods included volume rendering ( VR) and computed volume rendering( CVR).3. The evaluation of hepatic arterial anatomy in MSCTA was performed by 2 radiologists. Hepatic arterial pathway seen in operation was documented.
