This study was intended to elucidate, on a histological basis, the origin of the angiographic abnormalities seen in three pancreatic carcinoma cases and three chronic pancreatitis cases. Irregular encasement and/or occlusion of the extrapancreatic large arteries were revealed to have resulted from serrated deformity and contraction of the arterial wall, which was surrounded by fibrosis and invasive carcinoma cells. Both of these changes in combination were characteristic in carcinoma cases, but the arterial walls never succumbed to tumor invasion. Arterial occlusions due to intimal thickening in the small arteries were morphologically similar in cases of carcinoma and chronic pancreatitis.
本研究旨在从组织学角度阐明3例胰腺癌和3例慢性胰腺炎病例中血管造影异常的起源。结果显示，胰腺外大动脉的不规则包绕和/或闭塞是由动脉壁的锯齿状畸形和收缩所致，动脉壁被纤维化和浸润性癌细胞所包围。这两种变化共同存在是癌病例的特征，但动脉壁从未被肿瘤侵犯。小动脉内膜增厚导致的动脉闭塞在癌病例和慢性胰腺炎病例中形态相似。
