摘要
目的 明确腘动脉分区的解剖学意义,探讨腘动脉的解剖学特征对腘动脉硬化闭塞性病变腔内治疗的指导意义.方法 选择自2011年8月至2013年7月我院血管外科收治的部分股腘动脉硬化闭塞症113例共118条肢体.在行腔内治疗时于病变开通前对腘动脉行屈膝位造影,观察腘动脉的弯曲形态,弯曲拐点的部位,分析其与腘动脉分区的关系;对行腘动脉支架治疗的病例于治疗后再行屈膝位造影观察弯曲形态和血流动力学的变化.结果 腘动脉存在多种弯曲形态,75.4％的弯曲拐点位于P2区,18.6％位于P1区,6.0％位于P3区.73例行腘动脉支架治疗的病例中,10例在治疗后发生腘动脉弯曲程度变化,6例发生远端血管扭曲.血管扭曲现象均出现于跨弯曲部支架治疗的病例中,其中5例在屈膝位出现血流动力学变化.结论 通过屈膝位造影能够更好地理解腘动脉分区的解剖学意义并了解腘动脉的弯曲形态,有助于提高位于不同分区内的腘动脉硬化闭塞性病变腔内治疗的合理性.
Objective To define the significance of the anatomical division and features of popliteal artery in popliteal angioplasty.Methods This study involved 118 lower limbs in 113 cases of femoropoliteal occlusive disease undergoing angioplasty in our center between August 2011 and July 2013.A bent-knee angiogram was taken before recanalization of the lesion.The flexion pattern and the location of flexion points of popliteal artery were collected to study their relationship with the division of popliteal artery.A post-procedural bent-knee angiogram was taken in case of popliteal stenting to assess any change in flexion angulation and distal flow.Results There are diverse flexion patterns in popliteal artery,75.4％ of the flexion points locate in P2 segment,18.6％ in P1,and 6.0％ in P3.On post-procedural bent-knee angiogram in 73 cases of popliteal stenting,10 had a more acute distal flexion angulation,distal artery kinking was observed in another 6 cases of which 5 had compromised distal flow.Artery kinking only occurred in cross-flexion-point stenting.Conclusions A better understanding of the division and anatomical features of popliteal artery can be obtained via bent-knee angiogram.This is of value to angioplasty for lesions in different popliteal divisions.
