Forty-one rats were subjected to a single blow in the femoral region from a heavy falling object. The contusion was directed towards the palpated femoral vessels in a standard manner. Transverse sections of the femoral artery and vein with branches, including adjacent muscle, were taken at 30 min, 24 hours, 2 weeks and 1 and 3 months after the injury and evaluated by light microscopy. The injuries to the femoral vessels and their branches at 30 min and 24 hours varied from partial destruction of the internal elastic lamina only to crush injury of the media together with thrombosis. Bleeding was always present. In the most severely injured arteries the vessel wall had ruptured. The findings at 2 weeks and 1 and 3 months were more discrete. The femoral vessels had remained patent, sometimes with permanent damage to the internal elastic lamina and rearranged architecture of the elastic tissue in the media. In a few cases recanalized thrombi were seen in arterial branches. Fibrosis of the femoral muscle was found at the level of trauma. Despite a single serious blow to the femoral region, however, there was no permanent major injury to the femoral artery or vein.
41只大鼠的股骨区域受到一个从高处落下的重物的单次撞击。以标准方式将挫伤部位对准可触及的股血管。在损伤后30分钟、24小时、2周、1个月和3个月时，获取包括相邻肌肉在内的股动脉和静脉及其分支的横切片，并用光学显微镜进行评估。损伤后30分钟和24小时时，股血管及其分支的损伤情况各异，从仅内弹性膜的部分破坏到中膜挤压伤并伴有血栓形成。总是存在出血情况。在损伤最严重的动脉中，血管壁已经破裂。2周以及1个月和3个月时的发现更为不明显。股血管保持通畅，有时内弹性膜有永久性损伤，中膜弹性组织的结构重新排列。在少数情况下，在动脉分支中可见再通的血栓。在创伤部位发现股肌纤维化。然而，尽管对股骨区域进行了单次严重撞击，但股动脉或静脉并未受到永久性的重大损伤。
