踝臂指数检测对下肢动脉疾病的诊断价值

Diagnostic value of detection of ankle brachial index in lower extremity arterial disease

目的探讨踝臂指数(ABI)检测对下肢动脉疾病(LEAD)的诊断价值。方法对92例经数字减影血管造影或CT血管成像证实的LEAD患者(患者组),采用无创伤全自动外周动脉检测仪测量ABI、脉搏波上行时间(UT)和脉搏体积记录波形(PVR)。另设90例无LEAD患者为对照组。结果患者组病变肢体的ABI值明显低于对照组,UT值较对照组延迟。患者组99肢(73%)病变肢体的PVR呈低钝波,33肢(24%)呈低平波,4肢(3%)未测出PVR。结论ABI检测对快速筛查和诊断LEAD具有较高的临床实用价值。

Objective To explore the diagnostic value of detection of ankle brachial index(ABI) in the lower extremity arterial disease(LEAD).Methods In 92 aged patients(patient group) with LEAD determined by digital subtraction or CT angiography,measurement of ABI,upstroke time(UT) and pulse volume recording(PVR) was performed with a non-invasive automatic peripheral arterial device.Ninety patients without LEAD were selected to serve as controls.Results In the patient group,ABI of the affected limb was significantly lower than that of the control group.UT of the affected limb was significantly delayed than that of the control group.In the patient group,the low blunt waveform was found in 99 affected limb(73%),flat waveform was found in 33 affected limbs(24%),PVR was not measured in 4 affected limb(3%).Conclusions Detection of ABI has high clinical value to quickly sieve and diagnose the LEAD.
