摘要背景：本研究的目的是评估肝镰状动脉（HFA）的血管造影发生率和表现，并讨论其临床意义。
研究方法：前瞻性评价了53例采用数字减影血管造影术获得的肝脏血管造影片的HFA发生率、解剖特征和流速。我们分析了慢性肝病的背景是否影响HFA的发生率。本文报告33例肝肿瘤经导管动脉灌注化疗或栓塞化疗。我们注意到脐上皮肤并发症的发生。
结果：53例患者中13例（24.5%）在腹腔或肝动脉造影中观察到HFA。所有患者的HFA血流均慢于外周肝动脉血流。34例慢性肝病患者与19例正常肝脏患者的HFA发生率无显著性差异，1例HFA治疗后出现脐上红色皮疹，有胃切除史。
结论：HFA的血管造影发生率比以前报道的更常见。HFA在肝血管造影上的延迟性和持续性混浊被认为是鉴别HFA的关键。
AbstractBackground: The purpose of this study was to assess the angiographic incidence and appearance of the hepatic falciform artery (HFA) and discuss its clinical significance.
Methods: Hepatic angiograms of 53 patients obtained with digital subtraction angiography were prospectively evaluated with regard to incidence, anatomic features, and flow speed of the HFA. We analyzed whether the background of chronic liver disease affected the incidence of the HFA. Transcatheter arterial chemoinfusion or chemoembolization for liver tumors was performed in 33 patients. We noted the occurrence of supraumbilical skin complications.
Results: The HFA was observed in 13 (24.5%) of 53 patients on celiac or common hepatic angiograms. The blood flow of the HFA was slower than that of the peripheral hepatic arteries in all patients. No significant difference in the incidence of HFA between the 34 patients with chronic liver disease and the 19 patients with normal livers was found. One treated patient with an HFA and a history of gastrectomy developed a supraumbilical red skin rash.
Conclusion: The angiographic incidence of the HFA is more common than previously reported. The delayed and persistent opacification of the HFA on hepatic angiograms caused by its slow blood flow is considered the key to its identification.
