Fourteen patients candidates to surgery for liver neoplasms (7 primitive cancers and 7 liver metastases) underwent a prospective double-blind study with digital angiography and Doppler US. The latter demonstrated the presence of the hepatomesenteric artery in all the 3 patients with this anatomical variant. In 2 cases with an early origin of the common hepatic artery, Doppler US allowed the detection of unusual signals from the left hepatic artery but could not exclude its origin from the left gastric artery. The quality of US information concerning portal flow was equal or superior to that of digital angiography in all cases. The use of Doppler US is suggested before angiography when morphologic-functional information is needed concerning the portal vein. However, this method cannot replace angiography in the routine study of hepatic artery patterns.
14名肝脏肿瘤手术候选患者（7例原发性癌症和7例肝转移瘤）接受了一项关于数字血管造影和多普勒超声的前瞻性双盲研究。在所有3例存在这种解剖变异的患者中，多普勒超声显示了肝肠系膜动脉的存在。在2例肝总动脉起源较早的病例中，多普勒超声检测到来自左肝动脉的异常信号，但不能排除其起源于胃左动脉。在所有病例中，超声关于门静脉血流信息的质量与数字血管造影相当或更优。当需要关于门静脉的形态功能信息时，建议在血管造影之前使用多普勒超声。然而，在肝动脉模式的常规研究中，这种方法不能替代血管造影。
