Abstract

Objective　To investigate intrahepatic distribution of the left hepatic artery using 64-multi-slice computed tomography angiography（64-MSCTA）, and provide morphological data for treating liver diseases.　Methods　CT images of 120 volunteers were collected and dealt with volume rendering techniques (VRT).The data of left hepatic artery were measured and analyzed statistically.　Results　The length of the left hepatic arterial trunk was about （42.37±26.58）mm；the inner diameter of its beginning, midpoint and distal end were（3.06±0.70 ）,（2.82±0.68）, and（2.78±0.65）mm, separately. The frequency of the single trunk, dimidiate branchees, trichotomous branches and quadripartite branches were 4.2%, 63.3%, 28.3%, 2.5% respectively. The angle between endite branch and exite branch of left hepatic artery was about（80.21±23.36）°，While the length and the inner diameter of the starting point of exite branch were（42.80±29.11）mm and （2.25±0.70）mm, as well that of endite branch were （42.90±22.70）mm, and（1.66±0.64）mm, respectively. The frequency of left hepatic artery dispersed to segment Ⅱ, Ⅲ, Ⅳ or segment Ⅱ, Ⅲ were 64.1% and 28.3%，and the aberrant left hepatic artery distributed to segment Ⅱ, Ⅲ，Ⅱor Ⅱ, or Ⅲ, Ⅳ were 5.0%, 3.3%，0.8%, respectively.　Conclusions　64-MSCTA is feasible to provide accurate morphological information for the liver. The intrahepatic distribution of the left hepatic artery was complex, and the dimidiate branch of the left hepatic artery is common. The left hepatic artery chiefly distributes to segment Ⅱ, Ⅲ and Ⅳ.
