Ten expanded polytetrafluoroethylene (PTFE) vascular grafts were implanted in dogs crossing the joint, performed as iliofemoral bypass. After 1, 3, 6, and 9 months the grafts were studied by light microscopy, scanning, and transmission electron microscopy. There was a good patency of all straight prostheses. The pre- and postkink areas showed thrombosis leading to stenosis. After 9 months endothelium was spread over all other parts of the luminal surface, including the kink area. Intramurally there was a focal ingrowth of fibroblastic cells with the characteristics of myocytes.
将10个膨体聚四氟乙烯（PTFE）血管移植物植入犬的关节交叉处，进行髂股旁路移植术。在1、3、6和9个月后，通过光学显微镜、扫描电子显微镜和透射电子显微镜对移植物进行研究。所有直管状假体的通畅性良好。扭结前后区域出现血栓形成导致管腔狭窄。9个月后，内皮细胞覆盖了管腔表面的所有其他部分，包括扭结区域。壁内有成纤维细胞灶性向内生长，具有心肌细胞的特征。
