多层螺旋CT血管造影对后胡桃夹综合征的诊断价值

The diagnostic value of multi-slice spiral CT angiography in posterior nutcracker syndrome

摘要:
目的初步探讨多层螺旋CT血管造影(MSCTA) 在后胡桃夹综合征诊断中的应用价值。
方法回顾性分析行MSCTA的后胡桃夹综合征1 4例，采用多平面重建、容积再现和最大密度投影进行血管重建。
结果 MSCTA的容积再现、多平面重建和最大密度投影可清晰地显示左肾静脉主干变异位置、形态和与周围血管的关系，并准确测量数据以了解左肾静脉主干受压迫的程度。
结论 MSCTA在诊断后胡桃夹综合征方面具有分辨率高、快速、准确、经济等优点，它提供的详尽信息可为尽快确定治疗方案提供依据。

Abstract:
Objective To preliminary explore the diagnostic value of Posterior Nutcracker Syndrome (PNCS) with multi-slice spiral CT angiography (MSCTA).
Methods Fourteen patients with PNCS diagnosed by MSCTA, were analyzed retrospectively, reconstructed vessel by volume rendering (VR), multi-planner reconstruction (MPR) and maximum intensity projection (MIP).
Results The location, shape and the relationship with the adjacent vessels in PNCS were showed clearly and accurately by VR, MPR and MIP.
Conclusion MSCTA is a feasible method with highly qualified images, high-speed, exact and economic in the diagnosis of PNCS. I t can provide exhaustive information for treatment.
