目的　为胰头癌手术及区域灌注疗法提供解剖学基础。  方法　新鲜成人标本15例灌注红色乳胶，解剖胰头及其周围的血管，测量相关数据。新鲜成人标本6例灌注聚乙烯醇-氧化铈用于血管显影，行CT扫描及三维重建。  结果    胰头主要血供来源于胰十二指肠上前、下前动脉，胰十二指肠上后、下后动脉及胰十二指肠前、后动脉弓；胰十二指肠前动脉弓和后动脉弓在胰头的最上端、最下端和十二指肠大乳头水平与十二指肠的距离分别是（1.08±0.21）、（1.23±0.22）、（1.12±0.25）cm和（1.15±0.28）、（1.25±0.24）、（1.05±0.25）cm；胰头血管的三维重建可以直观立体显示胰头血管的空间位置关系。  结论　保留十二指肠的胰头癌手术时，为避免损伤胰十二指肠前、后动脉弓，胰头部的缝线距十二指肠左侧不应低于1.5 cm；胰头血管的三维重建模型可为胰头外科手术、介入治疗等提供指导。

Objective　To investigate the applied anatomy of the blood supply of the pancreatic head, and provide anatomic basis for surgery in the pancreatic head and the Artery-perfusion Chemotherapy.  Methods　Anatomical observations was carried out to investigate the relationship of the blood supply in pancreatic heads of 15 fresh adult specimens which are injected with red-colored latex. 6 fresh adult specimens are injected with polyvinyl alcohol-ceria for CT scan, the data of which are used for three-dimensional reconstruction.  Results　The main blood supply of pancreatic head are: anterior superior pancreaticoduodenal artery, posterior superior pancreaticoduodenal artery, anterior inferior pancreaticoduodenal artery, posterior inferior pancreaticoduodenal artery, the anterior and posterior arterial arcades. The distances of the anterior pancreaticoduodenal arch and posterior pancreaticoduodenal arch at the top of the caput pancreas, major duodenal papilla, the bottom of the caput pancreas to duodenum were (1.08±0.21) cm, (1.23±0.22) cm, (1.12±0.25) cm and (1.15±0.28) cm, (1.25±0.24) cm, (1.05±0.25) cm, respectively. Three-dimensional reconstruction of blood vessels of the pancreatic head could display directly and stereoscopically the relationship of the various sources of blood supply to the pancreatic head.　Conclusion  In order to not injure the blood supply of the duodenum, we should keep the anterior and posterior arterial arcades of pancreaticoduodenal intact when we perform the excision surgery the pancreatic head cancer with reservation of the duodenum, which dictates that  the distance between the suture silk and the right border of caput pancreas should be kept longer than 1.5cm .Three-dimensional reconstruction of the blood vessels of pancreatic head can provide guidance for the surgery of the pancreatic head and interventional therapy.
