目的为经皮腹膜后隙牌肾静脉分流术（PRESS）技术的开发提供形态学依据。方法选取30例经甲醛固定的成人尸体标本，观察牌静脉、左肾静脉的走行及两者之间的关系，并对相关数据进行测量。结果牌静脉紧靠肠系膜上动脉起端右前方与肠系膜上静脉汇合为门静脉，脾静脉与左肾静脉在肠系膜上动脉起点左侧位置关系较为恒定。结论经股静脉的插管须先进入左肾静脉，然后在肠系膜上动脉起端左侧穿向脾静脉。 Objective To provide a morphological basis for the development of percutaneous retroperitoneal shunt renal vein shunt (PRESS) technique. Methods Thirty adult cadavers, fixed by formaldehyde, were selected to observe the relationship between the branching vein and the left renal vein and the relationship between them. The related data were also measured. Results Venous vein close to the superior mesenteric artery right front and superior mesenteric vein confluence as the portal vein, splenic vein and left renal vein in the left superior mesenteric artery position more constant. Conclusion Intubation of the femoral vein must first enter the left renal vein and then penetrate the splenic vein to the left of the superior mesenteric artery.
