摘　　要：目的探讨胰腺周围血管的3D解剖结构及临床应用意义。方法应用GE64层CT对50例体检者进行扫描,采用Myrian系统对胰腺周围动脉、门静脉、脾静脉、肠系膜上静脉及肠系膜下静脉进行3D重建,并测量相关数据。结果腹腔干、肝总动脉、肝固有动脉、脾动脉、胃十二指肠动脉及肠系膜上动脉可完全显示;门静脉、脾静脉、肠系膜上静脉及肠系膜下静脉可完全显示;门静脉干长度为(44.28±10.23)mm,胰后干长度为(32.13±7.08)mm;门静脉与脾静脉之间的夹角可分为3型:Ⅰ型,<90°;Ⅱ型,=90°;Ⅲ型,>90°。30%肠系膜下静脉汇入脾静脉,56%汇入肠系膜上静脉,14%汇入脾静脉和肠系膜上静脉交汇点。结论术前可利用Myrian系统对胰腺周围血管行3D重建,为研究胰腺周围血管提供解剖学基础,并可减少胰腺手术风险。Objective To explore the 3-D anatomical structure of blood vessel around the pancreas and its clinical significance.Methods Fifty objects were scanned by 64-slice CT of GE,the artery,portal vein,spleen vein,superior mesenteric vein and inferior mesenteric vein were 3-D reconstructed by Myrian system,and the scientific data were recorded.Results The artery,portal vein,spleen vein,superior mesenteric vein and inferior mesenteric vein were all reconstructed;the length of portal vein was（44.28±10.23）mm and the length of post-pancreas trunk was（32.13±7.08）mm;the angle between portal vein and spleen vein were classified into three types：the angle of typeⅠ was〈90°,angle of typeⅡ was=90°,and angle of typeⅢ was〉90°.30% of the inferior mesenteric vein fed into the spleen vein,56%fell into the superior mesenteric vein and 14% came into the the meeting point of the spleen vein and superior mesenteric vein.Conclusion The 3-D reconstruction of blood vessels around the pancreas can provide the anatomical basis for surgeon and reduce the risk of pancreatic surgery before operation.
