本文观察46具尸体的胃后动、静脉,其结果:一、胃后动脉出现率为71.7±6.6％,胃后动脉起于脾动脉23例占69.7±8.0％,起于脾动脉上极支6例占18.2±6.7％,双胃后动脉4例占12.1±5.7％。二、胃后动脉起始处外径成人平均为1.81±0.52mm,儿童平均为0.98±0.25mm;终末部外径成人平均为1.45±0.48mm,儿童平均为0.75±0.23mm;胃后动脉长度成人平均为32.89±7.37mm,儿童平均为14.8±5.6mm。 三、胃后静脉出现率为56.5±7.3％,胃后静脉汇入脾静脉23例占88.5±6.3％,汇入脾静脉上极支3例占11.5±6.3％;胃后静脉汇入处的外径成人平均为1.61±0.85mm儿童平均为1.14±0.40mm。四、胃后动脉距腹腔干平均为29.27±15.19mm,胃后动脉距贲门平均为14.59±7.23mm,胃后静脉汇人脾静脉或脾静脉上极支处距门静脉平均为22.49±12.6mm。胃后动脉多有胃后静脉伴行,静脉以1支为多见。
The results of this study were as follows: First, the incidence of the posterior gastric artery was 71.7 ± 6.6%, and 23 cases of the posterior gastric artery originated from the splenic artery accounting for 69.7 ± 8.0% 6 cases accounted for 18.2 ± 6.7%, 4 cases of double gastric artery accounted for 12.1 ± 5.7%. Second, the average diameter of the posterior gastric artery at the beginning of the adult average 1.81 ± 0.52mm, the average child was 0.98 ± 0.25mm; the average diameter of the terminal part of the adult was 1.45 ± 0.48mm, the average child 0.75 ± 0.23mm; The average length of adults was 32.89 ± 7.37mm, the average child was 14.8 ± 5.6mm. Third, the incidence of gastric venous was 56.5 ± 7.3%, 23 cases of venous splenic vein invaded 23 cases accounted for 88.5 ± 6.3%, 3 cases of splenic vein superficial branch accounted for 11.5 ± 6.3%; Department of venous access The average diameter of adults 1.61 ± 0.85mm children average 1.14 ± 0.40mm. Fourth, the mean arterial pressure from the celiac artery was 29.27 ± 15.19mm, and the posterior gastric artery was 14.59 ± 7.23mm from the cardia. The average distance from the superior vena cava of the splenic vein or splenic vein to the posterior gastric vein was 22.49 ± 12.6mm. More after the gastric artery with gastric venous accompanying venules to more common.
