目的:评估腹腔干(CT)分支的形态,左胃(LGA),普通肝(CHA),来自哥伦比亚人口样本的尸体标本中的脾(SA)动脉。
方法:对在Bucaramanga的医学研究所接受法医尸检的人尸体腹部上段26块进行的描述性横断面研究,哥伦比亚。腹腔干的血管床,随后,用半合成树脂灌注.
结果:LGA的直径,CHA,SA为3.6±0.8mm,5,2±1.2mm,5.9±1.0mm,分别。统计上,LGA和SA是不同的(p=<0.001)。SA在8个(31%)样本中遵循线性轨迹,在4个(15%)中略有曲折,和曲折的14(54%)。弯曲指数为1.25±0.18。在CHA的分支中,肝固有动脉(PHA)直径4.8±1.2mm,长度18.8±9.1mm,而胃十二指肠动脉(GDdA)为4.1±0.8mm。在2例(7.7%)中,发现来自LGA的副肝动脉向左肝叶提供灌注.最后,在2例(7.7%)中,SA独立于腹主动脉。
结论:观察到的CT分支的出现发生率与文献报道的水平相同。表征,以及它们的变体,LGA,CHA,在上腹部段的外科手术中必须考虑SA,避免医源性并发症。
OBJECTIVE: to evaluate the morphology of the branches of celiac trunk (CT), left gastric (LGA), common hepatic (CHA), and splenic (SA) arteries in cadaveric specimens from a sample of a Colombian population.
METHODS: descriptive cross-sectional
study of 26 blocks from the abdominal upper segment of human cadavers who underwent forensic autopsies at the Instituto de Medicina Legal at Bucaramanga, Colombia. The vascular beds of the celiac trunk were, subsequently, perfused with a semi-synthetic resin.
RESULTS: the diameters of LGA, CHA, and SA were 3.6±0.8mm, 5,2±1.2mm, and 5.9±1.0mm, respectively. Statistically, LGA and SA were different (p=<0.001). SA followed a linear trajectory in 8 (31%) samples, slightly tortuous in 4 (15%), and tortuous in 14 (54%). The tortuosity index was 1.25±0.18. Of the branches of CHA, the proper hepatic artery (PHA) had 4.8±1.2mm in diameter and 18.8±9.1mm in length, whereas the gastroduodenal artery (GDdA) had 4.1±0.8mm. In 2 cases (7.7%), an accessory hepatic artery from the LGA was found to supply perfusion to the left hepatic lobe. Finally, in 2 cases (7.7%) the SA came independently from the abdominal aorta.
CONCLUSIONS: the observed emergence incidence of the CT branches from the same level as reported in the literature is lower. The characterization, along with their variants, of LGA, CHA, and SA must be considered in surgical procedures in the upper abdominal segment, to avoid iatrogenic complications.
