胎儿输卵管的形态学研究

MICROVASCULATURE OF CROSSING AREA OF LATERAL THORACIC-LATISSMUS DORSI FLAP

目的:对胎儿输卵管进行了形态学观察和测量,为国人胚胎学的教学和科研提供参考资料.方法:选用泰安市的9～38周胎儿标本373例,观察输卵管的形态特征,测量其长度和重量.结果和结论:胎儿早期输卵管管径近似,1.5周始三段形态特征十分明显,20周后壶腹部常发生弯曲,测量的各数值均随胎儿的发育而增大,长度每月增加3～5mm,重量4个月前每月增加2～3mg,5个月始每月增加 40～50mg.

To provide microvasculature data for the union transplantation of the lateral tho-racic and latissmus dorsi flap. Methods: 6 new adult cadavers were injected with ink and forma-lin. The crossing area of the lateral thoracic and latissmus flap was divided into eight regions, from which tissues were cut and made into serial sections. The morphological characteristics of the microvascular architecture of these tissue sections, including the vascular network density and the vascular network areas were observed and calculated. Results: There were five layers in the skin of the lateral thoracic and latissmus dorsi flap. The vascular network was found to be denser in the reticular layer, fascia superficialis and fascia profunda, but less dense in the fascia superfi-cialis, fascia profunda and reticular layer. Conclusion: There are plentiful microvascular anasto-moses in the crossing area of the lateral thoracic and latissimus dorsi skin flap.
