The purpose of this work was to illustrate the CT appearance of the independent origin of the hepatic and splenic arteries from the abdominal aorta.
A retrospective review of available scans from 159 consecutive contrast-enhanced abdominal CT examinations was undertaken to document the frequency with which this vascular variant is seen at helical CT.
Independent origin of the hepatic and splenic arteries was seen in 2 of 159 examinations (1.3%). This correlates well with the 1% incidence reported in the angiographic and surgical literature.
Independent origin of the hepatic and splenic arteries from the aorta should be seen in approximately 1% of abdominal CT examinations. Knowledge of this vascular variant and its CT appearance may prevent confusion or mislabeling.
本研究旨在阐述肝动脉和脾动脉独立起源于腹主动脉的CT表现。
回顾性分析159例连续的腹部增强CT扫描，记录螺旋CT检查中该血管变异的出现频率。
159例检查中有2例（1.3%）出现肝动脉和脾动脉独立起源。这与血管造影和外科文献报道的1%发生率相符。
在大约1%的腹部CT检查中可见肝动脉和脾动脉从主动脉独立起源。了解这种血管变异及其CT表现可避免混淆或错误标记。
