We studied the morphological modifications of the popliteal artery during knee flexion. An anatomical, radiological study consisted of analysis of lateral arteriographs in different degrees in joint flexion followed by dissection to reveal the anatomical structures involved in the morphological adaptation of the popliteal artery to joint movement. In five non-atheromatous volunteers, 15 MRI angiographic sequences were done at the level of the knee in extension and flexion. The arteriographs and angio MRI showed that as joint flexion increased tortuosities appeared in the supra-articular upper popliteal artery while the middle and lower parts of the popliteal artery kept an even curve retracted from the posterior surface of the joint. Dissection seemed to show that this arterial adaptation occurred between two fixed points, one proximal (the adductor canal) and the other distal (the origin of the anterior tibial artery). Angio MRI seems to be a future route for the assessment of the limb vessels. The contrasting behaviour of the different segments of the popliteal artery allows us to understand better the pathophysiology of trauma and malpositions of the popliteal arterial trunk.
我们研究了膝关节屈曲过程中腘动脉的形态学改变。一项解剖学、放射学研究包括对不同程度关节屈曲时的外侧动脉造影进行分析，随后进行解剖以揭示参与腘动脉形态适应关节运动的解剖结构。在5名无动脉粥样硬化的志愿者中，于膝关节伸直和屈曲位进行了15次磁共振血管造影序列检查。动脉造影和血管造影磁共振成像显示，随着关节屈曲增加，腘动脉上关节段出现迂曲，而腘动脉中下段保持从关节后表面退缩的平滑曲线。解剖似乎表明这种动脉适应发生在两个固定点之间，一个近端（收肌管），另一个远端（胫前动脉起始处）。血管造影磁共振成像似乎是评估肢体血管的未来途径。腘动脉不同节段的不同表现使我们能更好地理解腘动脉主干创伤和错位的病理生理学。
