摘 要:目的为胰病变的断层影像诊断和外科治疗提供实用的形态学依据。方法在30例成人上腹部连续冠状断层标本及2例尸体腹部和5例健康成人上腹部磁共振(MRI)冠状图像上,研究冠状断面上胰的分部、毗邻和大小。结果在经肝门静脉左支角部的断面(A10)上胰颈首先出现,胰尾消失在经左右肾窦后份和脾门的断面(A20)上。在连续冠状断面上,胰集中出现于下腔静脉后缘前54 mm和后12 mm的范围内。在经肠系膜上静脉的断面(A12)上,胰颈位于肠系膜上静脉的前方,其最大上下径和最大左右径分别为20.93±3.61 mm和10.09±3.31mm。在经肝门静脉主干的断面(A13)上,胰头位于肝门静脉主干右下方和十二指肠降部的左前方,其最大上下径和最大左右径分别为46.58±6.44 mm和35.56±6.57 mm。在经下腔静脉前份和左肾静脉的断面(A15)上,胰体的左侧份位于脾静脉前方和左肾血管的上方,其最大上下径和最大左右径分别为28.16±5.31 mm和51.27±11.80 mm。在经下腔静脉后份和主动脉裂孔的断面(A17)上,胰尾位于左肾外上方、脾门和胃底之间,其最大上下径和最大左右径分别为21.13±2.06 mm和34.11±6.03 mm。结论在冠状断面上,肠系膜上静脉是识别胰颈的标志,下腔静脉和左肾静脉分别是识别胰头和胰体的标志,脾动、静脉和左肾是识别胰尾的标志。Objective The purpose of this study was to provide practical anatomic data for the imaging diagnosis and surgical treatment of the diseases of the pancreas. Methods The division, adjacency, and size of the pancreas on the coronal plane were investigated using 30 sets of serial coronal sections of upper abdomen of Chinese adult cadavers, MR image of the abdomen of 2 cadavers,and MR image of upper abdomen of 5 Chinese adult healthy volunteers. Results The pancreatic neck was usually visualized on the section through the angular part of left hepatic portal vein( A10 ). The pancreatic tail disappeared on the section through the posterior parts of left and right renal sinus and splenic hilus ( A20 ) . The pancreas was visualized mainly on the successive coronal sections ranging from 54 mm to 12 mm before and after the posterior margin of inferior vena cava respectively. On the section through the superior mesenteric vein(A12 ), the pancreatic neck was located anterior to the superior mesenteric vein and its maximal superoinferior, and maximal left and right diameters is (20.93 ± 3.61 ) mm and (10.09 ± 3.31 ) mm respectively. The pancreatic head was situated the inferior and right to the trunk of hepatic portal vein and the anterior and left to the descending part of duodenum and its maximal superoinferior, and maximal left and right diameters is (46.58 ± 6.44) mm and (35.56 ± 6.57) mm respectively on the section through the trunk of hepatic portal vein(A3 ) . On the section through the anterior part of inferior vena cava and left renal vein( A15 ), the left part of pancreatic body was visualized in front of the splenic vein and the superior to left renal blood vessels and its maximal superoinferior, and maximal left and right diameters is (28.16 ± 5.31 ) mm and (51.27 ± 11.80) mm respectively. The pancreatic tail was situated the superolateral to left kidney and between the splenic hilum and the fundus of the stomach and its maximal superoinferior, and maximal left and
