Abstract：
BACKGROUND: Understanding the variations of abdominal vascular structures is important for preventing complications of abdominal surgical procedures for gastrointestinal disease such as necrotizing enterocolitis or others that may arise in patients with congenital cardiac disease. We analysed the coeliac trunk and its branches in children with congenital heart disease to determine whether there is a greater prevalence of associated vascular abnormalities.
METHODS: We retrospectively analysed thoracic computed tomography (CT) angiograms performed in our hospital in paediatric patients with congenital heart disease. We documented the anatomical variations observed in abdominal sections in which the coeliac trunk and hepatic arteries were included in the field of view. We used the Uflacker classification to describe anatomical variants of the coeliac trunk, and the Michels classification and its modified version (Hiatt classification) to describe the anatomy of the hepatic artery system.
RESULTS: Our study included 178 patients with congenital heart disease. We identified coeliac trunk variants in 10.7% of the patients. Gastrosplenic trunk was to the most prevalent variant, amounting to 5.6% of total cases. We found hepatic artery variations in 19.1% of the patients. According to the Michels classification, the prevalence of accessory left hepatic artery arising from the left gastric artery as 4.5%, compared to 6.7% based on the Hiatt classification.
CONCLUSIONS: The prevalence of coeliac trunk and hepatic artery variations in patients with congenital heart disease was not greater in our study compared to other series in the literature. Clinicians must be vigilant about the variations detected in multislice CT scans to avoid complications resulting from vascular abnormalities, especially in patients who undergo abdominal surgery.

摘要：
背景：了解腹部血管结构的变化对于预防胃肠道疾病如坏死性小肠结肠炎或其他先天性心脏病患者的腹部外科手术并发症很重要。我们分析了先天性心脏病患儿的腹腔干及其分支，以确定相关血管异常的患病率是否更高。
方法：我们回顾性分析了我院先天性心脏病患儿的胸部CT血管造影。我们记录了在视野中包括腹腔干和肝动脉的腹部切片中观察到的解剖变化。我们使用Uflacker分类来描述腹腔干的解剖变异，和Michels分类及其修改版本（Hiatt分类）来描述肝动脉系统的解剖结构。
结果：我们的研究包括178例先天性心脏病患者。我们在10.7%的患者中发现了腹腔干变异。胃脾主干是最普遍的变异体，占总个案的5.6%。我们在19.1％的患者中发现了肝动脉变异。根据Michels分类,从胃左动脉产生的副肝左动脉的患病率为4.5%，相比之下，根据希亚特分类，这一比例为6.7%。
结论：在我们的研究中，与其他文献相比，先天性心脏病患者腹腔干和肝动脉变异的患病率并不高。临床医生必须警惕多层螺旋CT扫描中检测到的变异，以避免血管异常引起的并发症，尤其是接受腹部手术的患者。
