The vascular architecture of the pancreas has been described, but few reports indicate preoperative accuracy. During the last 3 years, selective superior mesenteric and celiac angiography was performed in 471 patients. In 35 of these patients, additional selective angiography of the superior pancreaticoduodenal and inferior pancreaticoduodenal arteries was performed to reveal the detailed vascular pattern of the pancreas and its surrounding structures. Exploratory surgery was performed in all patients except the four control subjects. The angiographic findings reflected a poorly vascularized infiltrating lesion with invasion of the blood vessels and serpiginous encasements. Peripancreatic extension of the tumor indicated nonresectability. In early pancreatitis, the pancreas showed increased vascularity and occasional stretched vessels. In more advanced pancreatitis, the arteries were prominent and irregular with increased parenchymal accumulation of contrast medium in the capillary phase. In pseudocysts of the pancreas, the only finding was stretching of the vessels around the lesion. A well circumscribed lesion with increased contrast medium in the capillary and venous phases diagnostic of pancreatic adenoma. Pancreatic angiography is an important diagnostic tool in evaluating and staging pancreatic neoplasms.
胰腺的血管结构已被描述，但很少有报告表明术前诊断的准确性。在过去3年中，对471例患者进行了选择性肠系膜上动脉和腹腔动脉造影。其中35例患者还进行了胰十二指肠上动脉和胰十二指肠下动脉的选择性造影，以揭示胰腺及其周围结构的详细血管模式。除4名对照受试者外，所有患者均接受了探查性手术。血管造影结果显示为血管化不良的浸润性病变，伴有血管侵犯和匐行包绕。肿瘤的胰周扩展提示不可切除。在早期胰腺炎中，胰腺血管增多，偶尔可见血管拉长。在更晚期的胰腺炎中，动脉突出且不规则，在毛细血管期实质内造影剂积聚增加。在胰腺假性囊肿中，唯一的发现是病变周围血管拉长。在毛细血管期和静脉期造影剂增加的边界清晰的病变可诊断为胰腺腺瘤。胰腺血管造影是评估胰腺肿瘤和进行分期的重要诊断工具。
