Celiac trunk usually trifurcates and supplies the organs in the supracolic compartment. The vascular variations are common in this region. There are reports on the variant course of right hepatic artery (RHA). The tortuous RHA forming a caterpillar hump is a rare finding and also its providing origin to gastroduodenal artery (GDA) is an important observation. During routine dissection of abdomen of approximately 60-year-old male cadaver, concurrent arterial variations were observed. The celiac trunk bifurcated into splenic and common hepatic arteries. The left gastric artery arose from the abdominal aorta. The common hepatic artery was tortuous and divided into right and left hepatic arteries in front of portal vein. The RHA gave origin to GDA and then made a characteristic loop around the bile duct with the convexity to the right side. Knowledge of arterial variations of celiac trunk and its branches is useful in planning and executing the radiological interventions and surgeries in the supracolic abdominal compartment.
腹腔干通常分为三支，为结肠上区的器官供血。该区域血管变异很常见。有关于右肝动脉（RHA）变异走行的报道。形成毛虫样隆起的迂曲右肝动脉是一种罕见发现，其为胃十二指肠动脉（GDA）供血也是一项重要观察结果。在对一名约60岁男性尸体进行腹部常规解剖时，观察到了同时存在的动脉变异。腹腔干分为脾动脉和肝总动脉。胃左动脉发自腹主动脉。肝总动脉迂曲，在门静脉前方分为右肝动脉和左肝动脉。右肝动脉发出胃十二指肠动脉，然后围绕胆管形成一个特征性的袢，凸向右侧。了解腹腔干及其分支的动脉变异情况，有助于在结肠上腹部区域规划和实施放射介入及手术。
