本研究的目的是通过回顾股动脉造影来分析腘动脉分支的变化。 2004年至2006年间，对621名患者进行了双下肢数字减影血管造影术。我们回顾性回顾了这 1242 幅动脉造影图，以分析腘动脉的分支模式。在1242个肢体中，1108个肢体（89.2%）具有正常的腘动脉分支模式。 105 名患者（66 名男性，39 名女性；76 名单侧，29 名双侧）的其余 134 个肢体（10.8%；65 个右肢，69 个左肢）显示出七种不同的分支模式：发育不良或再生性胫后动脉 (PT)（n = 63，5.1%）；胫前动脉 (AT) 发育不全或再生障碍 (n = 21, 1.7%)；三叉（n = 19，1.5%）； AT 来源较高（n = 15，1.2%）；发育不全或再生障碍性 PT 和 AT (n = 10, 0.8%)； PT 起源高（n = 5，0.4%）；和前胫腓干 (n = 1, 0.1%)。当一侧肢体的腘动脉分支模式正常时，另一侧的腘动脉分支模式有 13% 的可能性出现变异。当一侧肢体的分支模式发生变异时，另一侧也有 28% 的可能性发生变异。腘动脉分支的变化并不少见。了解这些变化对于评估下肢动脉造影非常重要，并且对血管外科医生和介入放射科医生具有临床意义。
The purpose of this study was to analyze the variations in branching of the popliteal artery by reviewing femoral arteriograms. Between 2004 and 2006, digital subtraction angiographies of both lower extremities were performed in 621 patients. We reviewed these 1242 arteriograms retrospectively in order to analyze the branching pattern of the popliteal artery. Of the 1242 extremities, 1108 extremities (89.2%) had normal branching pattern of the popliteal artery. The remaining 134 extremities (10.8%; 65 right, 69 left) in 105 patients (66 men, 39 women; 76 unilateral, 29 bilateral) showed seven variant branching patterns: hypoplastic or aplastic posterior tibial artery (PT) (n = 63, 5.1%); hypoplastic or aplastic anterior tibial artery (AT) (n = 21, 1.7%); trifurcation (n = 19, 1.5%); high origin of AT (n = 15, 1.2%); hypoplastic or aplastic PT and AT (n = 10, 0.8%); high origin of PT (n = 5, 0.4%); and anterior tibioperoneal trunk (n = 1, 0.1%). When the branching pattern of the popliteal artery is normal in one extremity, there is a 13% probability the other side will be a variant pattern. When the branching pattern is variant in one extremity, there is a 28% probability the opposite side will also contain a variation. Variations in branching of the popliteal artery are not uncommon. Awareness of these variations is important for evaluation of the lower extremity arteriograms and has clinical implications for vascular surgeons and interventional radiologists.
