下肢动脉病变的二维彩色多普勒血流图检查

目的　评价２ＤＣＤＦＩ在诊断下肢动脉病变中的应用。方法　对３０ 例患下肢动脉病变的患者进行２ＤＣＤＦＩ检查，并与血管造影和／ 或手术病理对照。结果　２ＤＣＤＦＩ诊断符合率为９６－７％ ，３０ 例中患有动脉硬化性闭塞１６ 例，血栓闭塞性脉管炎１０ 例，急性动脉栓塞及多发性大动脉炎各２ 例。共有患肢４０ 条，超声表现中：内膜增厚３８条（９５％ ），单发或多发斑块２６ 条（６５ ％） ，伴钙化２１ 条（５２．５ ％ ），管腔狭窄２５ 条（６２．５ ％） ，完全闭塞１５ 条（３７．５％ ），血栓形成１５ 条（３７－５ ％） 。结论　２ＤＣＤＦＩ检查与临床资料结合诊断下肢动脉病变有较大的价值。

2D Color Doppler Flow Imaging Examination of Arterial Diseases in Lower Limbs

Objective To evalute the appliance of 2D CDFI in diagnosing arterial diseases in lower limbs.Methods 2D CDFI was used and compared with angiography and/or operation pathology in 30 cases suffering from arterial diseases in lower limbs.Results The diagnostic coincident rate of 2D CDFI was 96 7%.In 30 cases there were 16 arteriosclerotic occlusion,10 thromboangiitis obliterans,2 acute arterial embolism and 2 multiple aorto arteritis.There were 40 lower limbs with lesions.US showed:endometrial hyperplasia in 38 limbs,atheromatous plaqus in 26 limbs,arterial stenosis in 25 limbs,arterial occlusion in 15 limbs and thrombosis in 15 limbs.Conclusion 2D CDFI combined clinical material has great applied value in diagnosing arterial diseases in lower limbs.
