腘动脉硬化性病变腔内治疗的技术要点

在下肢动脉硬化闭塞症的腔内治疗中，合理处理腘动脉病变是备受关注的焦点。笔者从腘动脉解剖特点、治疗方式选择、是否放置支架以及支架的选择等方面论述腘动脉硬化性病变腔内治疗的技术要点，指出：避免于腘动脉段行支架治疗应是腔内治疗的首要原则；对于无法避免行支架治疗者，选择合适的支架及合理的支架治疗策略，减少支架植入后对腘动脉原有形态特征及血流动力学的改变是提高远期疗效的关键。

Technical tips for endovascular treatment of popliteal arteriosclerotic lesions

In endovascular therapy of lower-extremity arteriosclerosis obliterans, attention has been focused on the proper management of the lesions involving the popliteal artery. In this paper, the author discussed the technical essentials of endovascular treatment for popliteal arteriosclerotic lesions from aspects of the anatomical features of the popliteal artery, choice of treatment method, whether stent placement is required and stent selection. It is pointed out that avoidance of stent implantation in the popliteal segment should be considered as the overriding principle; for those cases where stent treatment must inevitably be performed, the essential strategy for improving long-term efficacy is based on the appropriate selection of stent and a suitable stent implantation strategy, and lessening the alterations of the initial morphological pattern and hemodynamics of the popliteal artery after stent implantation.
