胃后动、静脉的应用解剖学

Applied Anatomy of the Posterior Gastric Artery and Vein

用100具尸体(成尸66、童尸34),观测了胃后血管。(1)胃后动脉出现率88.0%,1支者占89.8%,2支者占10.2%.起自脾动脉中1/3段者居多(78.6%),有94.9%的胃后动脉穿入胃底部后壁。该动脉平均长3.5cm,外径1.5mm.(2)胃后静脉出现率87.0%,1支者占92.0%.注入脾静脉中1/3段者较多(76.6%),该静脉平均长4.4cm,外径1.7mm。

The posterior gastric artery and vein of 100 cadavers(66 adults and 34 children)were studied.The posterior gastric artery was found in 88.0%of the cases,89.8%of which had only a single-trunk and 10.2%had a double-trunk.The artery was found to originating from the mid-third of the splenic artery in 78.4% and perforating the posterior wall of the stomach in 94.9%of the cases.The average length of the artery was 3.5cm and the diameter at its origin was 1.5mm.the posterior gastric vein was found in 87.%of the cases,92.0%of which had a single-trunk.76.6%of the veins drained into the mid-third portion of the splenic vein.The average length of the vein and the diameter at its terminal were 4.4cm and 1.7mm respectively.
