多层螺旋CT血管造影在下肢血管闭塞性病变中的应用

目的：探讨多层螺旋CT血管造影在下肢血管闭塞性病变中的应用价值。方法：对22例临床疑有下肢血管闭塞性病变患者行多层螺旋CT血管造影及血管三维重建，并结合临床资料分析CT血管造影技术及应用价值。结果：MSCT动脉造影诊断下肢动脉病变10例，8例为下肢动脉硬化闭塞症，1例为血栓闭塞性脉管炎，1例为下肢动脉急性栓塞。其中4例行DSA检查，结果与MSCTA相符。MSCT静脉造影诊断下肢静脉病变12例。4例为髂静脉压迫综合征，6例为下肢深静脉血栓，2例MSCTV未见异常。其中6例行DSA检查，4例结果与MSCTV相符。结论：多层螺旋CT血管造影诊断下肢血管闭塞性病变有较高的临床应用价值。

Multislice spiral CT angiography for evaluation of vascular occlusive diseases of lower extremity

Objective To assess the value of multislice spiral CT angiography (MSCTA) in detecting vascular occlusive diseases of lower extremity. Methods Twenty-two suspected patients with vascular occlusive diseases of lower extremity underwent multislice spiral CT angiography and 3D reconstruction. The CT angiography technique and its diagnostic value were analyzed with clinical data. Results Ten cases of lower extremity arterial diseases were diagnosed by MSCTA. There were 8 cases of lower extremity arteriosclerotic occlusive disease, 1 case of thromboangiitis obliterans, 1 case of lower extremity artery atheroembolism. Four cases underwent DSA. The results were accordant between DSA and MSCTA. Twelve cases of lower extremity venous diseases were diagnosed by MSCT venography. There were 4 cases of iliac vein compression syndrome, 6 cases of deep vein thrombosis. No abnormality was seen in 2 cases. Six cases underwent DSA. The results were accordant between DSA and MSCT venography in 4 cases. Conclusion Multislice spiral CT angiography is of great value in detecting vascular occlusive diseases of lower extremity.
