永存坐骨动脉的超声诊断价值探讨

摘要

Objective To study the clinical value of color Doppler ultrasonography in the persistent sciatic artery.Methods The ultrasonographic images of eleven patients with persistent sciatic artery diagnosed by CT angiography or digital subtraction angiography were retrospective analyzed,the ultrasonographic features were summarized.Results The sciatic artery showed the enlarged internal iliac artery,which continued into the thigh in a posterior location,the sciatic artery described a tortuous course toward the knee,slowly filling normal-appearing popliteal artery in 8 cases,there were no connection with popliteal artery in 1 cases.The common femoral artery and superficial femoral artery was dysplasia in 7 patients,which was thinner than the popliteal artery.Conclusions The ultrasonography is the effective imaging method for diagnosis of the persistent sciatic artery.%目的 探讨彩色多普勒超声对永存坐骨动脉的诊断价值.方法 对经CT血管成像或数字减影动脉造影证实的9例永存坐骨动脉声像图表现进行回顾性总结分析.结果 坐骨动脉声像图表现为增粗的髂内动脉发出粗大分支并于臀部后方肌肉下行,其中8例患者最终延续为腘动脉,1例患者未与腘动脉相连.9例患者中7例股总动脉及股浅动脉发育纤细,较腘动脉内径明显变小.结论 彩色多普勒超声是诊断永存坐骨动脉有价值的影像学方法.
