肝静脉脉冲多普勒图对三尖瓣返流的诊断评价

The Value of pulsed Doppler Flow Pattern of Hepatic Vein in Diagnosing Tricuspid Regurgitation

65例患者同时接受彩色多普勒血流图及肝静脉脉冲多普勒图(HVP)检查以评价HVP 诊断三尖瓣返流(TR)的临床价值。HVP 诊断 TR 的标准为出现收缩期逆向波或收缩期前向波与舒张期前向波的比值小于1。结果表明,在窦性心律患者 HVP 诊断的特异性高,但敏感性很低。在房颤及有心脏手术史的患者,即使无 TR 存在亦可出现类似 TR 的 HVP 图形而影响其价值。

Pulsed Doppler flow pattern of hepatic vein (HVP)was used to diagnose tricuspid regurgitation (TR)in one hundred and sixty five patients with the following criterion:occuranee of systolic retro- grade flow (SRF)or the ratio of systolic intrograde flow to diastolic intrograde flow (SIF/DIF)less than 1.The result was compared with that using color Doppler flow imaging.In patients with sinus rhythm and without precedent cardiac surgery,hepatic flow pattern had high diagnostic specificity but low sen- sitvity.In patients with atrial fibrillation but without TR,the HVP appeared similar to that with TR as the hepatic flow pattern was influenced by atrial fibrillation and cardiac surgery,so the diagnostic val- ue was influenced as well.
