目的探讨64层螺旋CT直接法静脉造影在下肢深静脉血栓(DVT)中的诊断价值。资料与方法19例临床怀疑DVT患者行64层螺旋CT直接法下肢深静脉造影检查,着重分析DVT的CT征象,探讨影响其诊断准确性的因素。结果64层螺旋CT直接法静脉造影对DVT显示较好,在15例患者中共发现DVT25处,分别位于髂静脉(4)、股静脉(7)、腘静脉(9)和腓静脉(5)。结论64层螺旋CT直接法下肢深静脉造影结合多种后处理技术可以清楚显示DVT,具有较高的临床应用价值。
Objective To investigate the diagnostic value of 64-slice spiral CT direct venography in the diagnosis of lower extremity deep venous thrombosis (DVT). Materials and Methods Nineteen patients with suspected DVT underwent deep venous angiography in 64 patients with DVT. The CT features of DVT were analyzed emphatically, and the factors influencing the diagnostic accuracy were discussed. Results 64-slice spiral CT direct venography showed better DVT. DVT25 were found in 15 patients, located in the iliac vein (4), femoral vein (7), popliteal vein (9) and peroneal vein (5) respectively. Conclusion 64-slice spiral CT direct method of lower extremity deep vein angiography combined with a variety of post-treatment techniques can clearly show DVT, has a high clinical value.
