Analysis, evaluation and classification of hepatic arterial supply variants and determination of their frequency distribution in CT-angiographies.
CT-angiographies of 1,568 patients were evaluated retrospectively for the period between January 1, 2010 and August 30, 2012. The hepatic arterial anatomy was assessed and categorized according to Michels's classification. So far unclassified variants were considered separately.
CT-angiographies of 1297 patients were included in the study. Type I according to Michels was seen in 937 cases (72.2 %), followed by type V in 114 patients (8.8 %) and type III in 83 patients (6.4 %). Type X could not be found in any of the patients. Not yet classified variants were discovered in 26 patients. The most frequent variant in this connection was a right hepatic artery originating from the superior mesenteric artery with the left hepatic artery originating from the left gastric artery (n = 10).
Michels's classification could be largely confirmed on the basis of a radiologically examined patient population. Not yet classified variants were categorized into subgroups of the existing classification.

分析、评估和分类肝动脉供应变异，并确定其在CT血管造影中的频率分布。
回顾性评估2010年1月1日至2012年8月30日期间1568例患者的CT血管造影。根据米歇尔分类法评估和分类肝动脉解剖结构。迄今为止未分类的变异单独考虑。
1297例患者的CT血管造影纳入研究。根据米歇尔分类法，I型见于937例（72.2%），其次是V型114例（8.8%）和III型83例（6.4%）。未发现任何患者有X型。26例患者发现了尚未分类的变异。最常见的变异是右肝动脉起源于肠系膜上动脉，左肝动脉起源于胃左动脉（n = 10）。
基于放射学检查的患者群体，米歇尔分类法在很大程度上得到了证实。尚未分类的变异被归类到现有分类的亚组中。
