本文在调查48例成人尸体中,发现有5例(10.4±0.4％)腹腔动脉和肠系膜上动脉共干起始于腹主动脉,其共干起始的状态都不尽相同,现报道如下。在5例共干变异中,有2例起始于第十二胸椎的下缘,2例起始于第十二胸椎与第一腰椎之间,另1例位于第一腰椎的中部。共干的起始部距膈肌主动脉裂孔的距离平均为0.96 0.32(0.7～1.5)cm,共干起始部分的长度在0.5cm～1.4cm之间,平均长为0.84±0.40cm。共干部分均以锐角自腹主动脉发出,其与腹主动脉的夹角平均为60°
In this paper, 48 adult cadaver studies found that 5 cases (10.4 ± 0.4%) of the celiac artery and superior mesenteric artery began in the common abdominal aorta, the state of its co-start are not the same, are reported below. Among the five co-stem variants, two started on the lower edge of the twelfth thoracic vertebra, two started on the twelfth thoracic vertebra and the first lumbar vertebra, and the other one on the middle of the first lumbar vertebra. The average distance between the common stem of the diaphragm and the aortic aorta was 0.96 0.32 (0.7-1.5) cm. The length of the common stem was between 0.5cm and 1.4cm with an average length of 0.84 ± 0.40cm. A total of dry parts were issued at an acute angle from the abdominal aorta, the angle between the aorta and the average 60 °
