目的:研究胎儿胃底后壁、贲门及食管腹段后壁的血液供应。方法:取30例胎儿尸体(6-10月),5%红色过氯乙烯填充胎儿胃的动脉血管,解剖观察胃底后壁、贲门及食管腹段的动脉血管的来源,测量动脉支数,血管长度,口径,分布。结果:胎儿胃底后壁、贲门及食管腹段后壁的血液由胃上动脉供给。胎儿胃上动脉起于左膈下动脉和胃左动脉,出现率为49.26%,1-3支不等,平均长(5.86±0.21)mm,起始点平均外径(0.32±0.08)mm。结论:胎儿胃底后壁、贲门及食管腹段后壁有1-3支动脉血管供应,即胃上动脉分支:食管支,胃底支,贲门支。动脉分布的研究为全胃切除和残胃血供提供形态学依据。
OBJECTIVE: To study the blood supply to the posterior wall of the fetal fundus, the cardia and the posterior wall of the esophagus. Methods: Forty fetuses (6-10 months) and 5% red perchlorethylene were filled in fetal stomach arterial blood vessels, the origin of arterial vessels in the posterior wall of stomach fundus, cardia and esophagus was dissected and artery count was measured. Vascular length, caliber, distribution. Results: Fetal fundus posterior wall, cardia and esophageal wall posterior wall of the blood supply by the superior arteriae. Fetal gastric artery from the left subphrenic artery and left gastric artery, the incidence was 49.26%, ranging from 1-3, with an average length (5.86 ± 0.21) mm, starting point average diameter (0.32 ± 0.08) mm. Conclusion: There are 1-3 arterial vessels in the posterior wall of gastric fundus, cardia and the posterior wall of the esophagus, namely the branch of the superior gastric artery: the esophagus branch, the fundus, the cardia branch. Arterial distribution studies provide a morphological basis for total gastrectomy and residual gastric blood supply.
