左肾静脉压迫综合征(left renal vein entrapment-syndrome)又称左肾静脉高压综合征或胡桃夹综合征(nutcracker syndrome, NCS),是指左肾静脉在受到机械性挤压后肾静脉血液回流受阻而引起的左肾静脉压力增高,继而出现的一系列临床症状。左肾静脉走行于腹主动脉(abdominal aorta)与脊柱之间受压所形成的NCS称之为后胡桃夹综合征(posterior nutcracker syndrome, PNCS),临床上较少见。本研究主要讨论及初步评价多层螺旋CT血管造影(multi-slice spiral CT angiography, MSCTA)对PNCS的诊断价值。

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. -
