CE-MRA诊断下肢动脉硬化性闭塞症的价值

目的：探讨CE—MRA在诊断下肢动脉硬化性闭塞症的应用价值。方法：对25例临床拟下肢动脉硬化性闭塞症的患者进行CE—MRA检查．并使用MIP等后处理方法分析。结果：24例MRA检查成功，本组患者显示右侧髂外动脉闭塞2例．腹主动脉狭窄2例，闭塞2例；股动脉狭窄4例，闭塞2例；胴动脉狭窄5例，小腿动脉狭窄3例，闭塞4例。其中1例由于患者不配合导致检查失败。结论：利用CE—MRA可直观、全面的诊断下肢动脉硬化性闭塞症，了解病变的范围和程度,是一种安全、准确、无创的检查方法。

Value of CE-MRA Angiography in Diagnosis of Arteriosclerotic Occlusive Disease of Lower Extremity

Objective To discuss the value of CE-MRA of lower extremity angiography in diagnosing Arteriosclerotic occlusive disease. Methods CE-MRA was performed on 25 patients with symptom of arteriosclerotic occlusive disease. CT angiograms were produced using maximal intensity projection. Results 24 examinations of CE-MRA were successful with 2 cases of straitness in right ailiaca communist, 2cases of straitness and 2 cases of occlusion in aorta abdominal, 4 cases of straitness and 2 cases occlusion in artery of femoral, 3 cases of straitness and 4 cases of occlusion in artery of crus. One case was failed for the patient himself. Conclusion CE-MRA of lower extremity angiography can monitor multiple arteries of Arteriosclerosis occlusive disease of lower limbs and observe the extent and range of lesions. It has high diagnostic accuracy in patients with lower extremity artery diseases, and it is a safe, no-trauma and effective method in lower extremity artery.
