Angiographic Anatomy and Significance of Celiac Artery in Rabbit / 实用放射学杂志

ABSTRACT

Objective To research the angiographic anatomy of celiac artery in rabbit.Methods 36 New Zealand big white rabbitswere included in this study,the angiography of celiac artery and hepatic artery via right femoral artery was performed,and the branchand diameter of celiac artery system were analysed.Results 66.7% of the celiac arterial opening localized at the level of T_(12) vertebral body low edge,gastrohepatic arterial truncus could been divided into three types : type Ⅰ(47.22%),tree-like branch;type Ⅱ(38.88%),trifurcate branch and type Ⅲ(13.90%),dichotomy branch.The length of proper hepatic artery was from 22.70 to 33.00 mm(26.64 mm?2.28 mm),the inner diameter of proper hepatic artery,left hepatic artery and right hepatic arteria was 0.60~1.20 mm(0.90 mm?0.16 mm),0.60~1.10 mm(0.72 mm?0.09 mm) and 0.50~1.00 mm(0.67 mm?0.09 mm) respectively.The segmental artery of liver could be displaied clearly by proper hepatic artery angiography.Conclusion To realize the angiographic anatomy of rabbit celiac artery would provide a useful help for transhepatic arterial interventional treatment of the liver VX_2 tumor model of rabbit.
