Objective To examine biomechanic change of vessel wall and re-stenosis after dilation of stenosed vena cava in dogs and to infer possible mechanisms of hypotonic luminal benign stenosis in an attempt to provide new evidence for clinical study of potential mechanisms of vena cava stenosis.

目的 通过实验动物研究，初步探讨下腔静脉狭窄扩张后的管壁生物力学特征的改变，推测再狭窄的可能机制。

BACKGROUND: Establishment of individual femoral model can describe the stereochemical structure of femoral accurately, which is conductive to measuring femoral anatomic forms. This model possesses unified standard, and removing the potential confounding factors, thus, it is more suitable for biomechanical test.

摘要背景：个体化股骨模型的建立，能够准确、完整地描述出股骨的立体结构，有助于测量股骨的解剖形态，这样的模型有统一的密度和机械性能，去除了个体之间性别、年龄、种族、骨质疏松程度、是否有骨病等混杂因素，用于生物力学测试更有意义。
