目的:研究肝动脉解剖变异的种类、发生率及临床意义。方法:回顾分析500例肝癌患者的肝动脉造影DSA资料,观察肝总动脉、肝固有动脉、肝右动脉、肝中动脉、肝左动脉的起始、走行、分布情况。并分别统计其发生率。结果:500例肝动脉造影中,正常型(M iche ls I型)325例,占65.0%.变异的肝动脉175例,占35.0%。175例变异的肝动脉中属于M iche ls已有分型的154例,占30.8%;属于M iche ls未分类的21例,占4.2%,其中多种变异共存8例,占4.0%。结论:肝动脉总的变异率与国外学者报道的基本一致,但变异的种类具有多样性、复杂性。全面了解这些变异特点对肝脏外科手术和肝脏血管内介入治疗有重要临床意义。
Objective: To study the types, incidence and clinical significance of anatomical variation of hepatic artery. Methods: A retrospective analysis of 500 cases of liver cancer in patients with hepatic arteriography data DSA, observed the common hepatic artery, hepatic artery, right hepatic artery, middle hepatic artery, left hepatic artery start, walk, distribution. And statistics of their incidence. Results: Of the 500 cases of hepatic artery angiography, 325 cases (65%) of the normal type (ICH type I), and 175 cases of hepatic artery variation (35.0%). There were 154 cases with M iche ls subtype in 175 hepatic arteries, accounting for 30.8%; 21 cases belonging to M iche ls unclassified, accounting for 4.2%, of which 8 cases (4.0%) coexisted with multiple mutations. CONCLUSION: The total variation rate of hepatic artery is basically consistent with that reported by foreign scholars, but the variety of variation is diverse and complex. A comprehensive understanding of these variations has important clinical implications for liver surgery and endovascular interventional therapy in the liver.
