目的：定位性动脉阻塞是动脉卡压综合征的重要原因。这项研究是为了确定的位置解剖学和生理条件的血管在窝在训练有素的和正常活跃的年轻男性和女性群体。我们假设，至少有一些无骨关节炎的个人可以闭塞腘动脉与腿部positioning.Methods：72肢进行了评估，在36例。无症状的受试者被分为四组：正常活跃的男性，正常活跃的女性，男性竞争性跑步者和女性竞争性跑步者。所有受试者均接受了无创性测试，包括静息节段性肢体压力和多普勒波形以及腿部处于中立位的彩色血流多普勒成像，然后进行膝关节伸展、主动和被动背屈以及足部跖屈。然后对无法通过定位闭塞腘动脉的受试者进行锻炼，并重复研究。磁共振成像，磁共振血管造影，进行了14个科目，与每一条腿在中立位和主动positioning.Results研究：位置腘动脉闭塞发生在38 72条肢体（53%）。组间比较无统计学显著性。89%的受试者每条腿的反应对称。静息时无法闭塞腘动脉的受试者在运动时均无法闭塞腘动脉。磁共振成像显示正常的解剖结构，在所有的科目，并显示腘动脉闭塞的位置是在水平的soloal吊索，与位置压缩由比目鱼肌，腓肠肌，跖肌，和腘muscules.Conclusion：腘动脉闭塞可以诱导在53%的科目与简单的腿部定位所造成的肌筋膜压迫。在根据腘血管的生理测试评价患者进行干预时，必须考虑到这一点。
Purpose: Positional popliteal artery obstruction is believed to be an important factor contributing to popliteal artery entrapment syndromes. This study was undertaken to define the positional anatomy and physiologic condition of the vessels in the popliteal fossa in groups of highly trained and normally active young men and women. We postulate that at least some symptom-free individuals can occlude the popliteal artery with leg positioning.Methods: Seventy-two limbs were evaluated in 36 subjects. Symptom-free subjects were recruited in four groups: normally active men, normally active women, male competitive runners, and female competitive runners. All subjects underwent noninvasive testing that included resting segmental limb pressures and Doppler waveforms and color-flow duplex imaging with the leg in the neutral position and then with knee extension with active and passive dorsiflexion and plantar flexion of the foot. Subjects unable to occlude the popliteal artery with positioning were then exercised, and studies were repeated. Magnetic resonance imaging, with magnetic resonance angiography, was conducted on 14 subjects, with each leg studied in the neutral position and with active positioning.Results: Positional popliteal arterial occlusion occurred in 38 of 72 limbs (53%). No intergroup comparisons were statistically significant. The response of each leg was symmetric in 89% of subjects. No subject who could not occlude the popliteal artery at rest was able to do so with exercise. Magnetic resonance imaging disclosed normal anatomy in all subjects and showed the location of popliteal occlusion to be at the level of the soleal sling, with positional compression by the soleus muscle, the lateral head of the gastrocnemius, the plantaris, and popliteus muscles.Conclusion: Popliteal arterial occlusion can be induced in 53% of subjects with simple leg positioning caused by myofascial compression. This must be considered when evaluating patients for intervention on the basis of physiologic testing of the popliteal vessels.
