The anatomical features of splenic segmental vessels in 102 human spleen autopsy specimens were analyzed. Methods applied were corrosion casting and post-mortem arteriography. The superior terminal splenic branch divided extracapsularly into 2.8+/-0.9 (range 2-5) and the inferior terminal splenic branch into 2.3+/-0.75 (range 2-5) branches per sample. The extracapsular lengths of the segmental branches ranged from 4.0 to 16.7 mm and the calibers from 0.4 to 2.2 mm. Superior polar arteries occurred in 31.3% and inferior polar arteries in 20.6% of cases. Their average extracapsular lengths were 39 mm and 31 mm, respectively. In conclusion, segmental splenic arteries have an extrasplenic origin and course, with an average length and caliber that allow surgical access and ligation, in order to achieve segmental dearterialization for hemostasis purposes and splenic preservation.
分析了102例人类脾脏尸检标本中脾段血管的解剖特征。采用的方法是铸型腐蚀和死后动脉造影。每个样本中，脾上终末支在包膜外分为2.8±0.9支（范围2 - 5支），脾下终末支分为2.3±0.75支（范围2 - 5支）。段支的包膜外长度为4.0至16.7毫米，管径为0.4至2.2毫米。31.3%的病例出现脾上极动脉，20.6%的病例出现脾下极动脉。它们的平均包膜外长度分别为39毫米和31毫米。总之，脾段动脉有脾外起源和走行，其平均长度和管径便于手术操作和结扎，以便为止血目的和保留脾脏而实现段动脉化。
