Abstract

OBJECTIVE

Evaluate whether common femoral artery (CFA) Doppler waveform assessment predicted the presence of significant iliac artery stenosis as visualised on magnetic resonance angiography (MRA).

METHOD

Three-year retrospective study of patients investigated using CFA Doppler waveforms and MRA. The patients were identified from vascular/radiology databases. Waveforms were reported real time as monophasic, biphasic or triphasic. Results were compared with MRA findings.

RESULTS

In 76 patients, 119 waveforms were assessed. MRA demonstrated 37 iliac vessels with significant stenosis. 32 (86%) had abnormal waveforms (monophasic/biphasic), 5 were triphasic. In 82 cases where MRA showed no significant stenosis, waveforms were abnormal in 35 (43%). Abnormal CFA waveforms have sensitivity of 86% and specificity of 57%. Monophasic waveforms alone were more specific (88%) but less sensitive (57%) for predicting iliac lesions.

CONCLUSION

Whilst CFA waveform morphology is a useful adjunct in detection of iliac disease, normal triphasic waveforms do not exclude iliac stenosis.

摘要

目的

评估股总动脉（CFA）多普勒波形评估是否可预测磁共振血管造影（MRA）显示的髂动脉狭窄的存在。

方法

对使用 CFA 多普勒波形和 MRA 进行检查的患者进行了为期 3 年的回顾性研究。从血管/放射学数据库中确定了这些患者。实时报告波形为单相、双相或三相。将结果与 MRA 结果进行比较。

结果

在 76 例患者中，评估了 119 个波形。MRA 显示 37 个髂血管存在明显狭窄。32 个（86%）出现异常波形（单相/双相），5 个为三相。在 82 例 MRA 显示无明显狭窄的病例中，35 例（43%）出现异常波形。异常 CFA 波形的敏感性为 86%，特异性为 57%。单相波形单独预测髂动脉病变的特异性（88%）更高，但敏感性（57%）较低。
