To determine the diagnostic accuracy of Doppler ultrasonography (US) in the detection of high-grade stenosis or occlusion of the celiac artery (CA) and superior mesenteric artery (SMA) and validate the previously reported Doppler US criteria.
During a recent 36-month period, 82 patients were prospectively examined with Doppler US of the splanchnic arteries and with lateral abdominal aortography, regardless of their abdominal symptoms. The previously reported diagnostic criteria with the fasting peak systolic velocity measurement were prospectively used in all patients. The results of Doppler US were compared with those of lateral aortography.
The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of Doppler US for the detection of 70% or greater CA stenosis or occlusion were 100%, 87%, 57%, 100%, and 89%, respectively; for 70% or greater SMA stenosis or occlusion, these values were 100%, 98%, 93%, 100%, and 99%, respectively.
Owing to its high accuracy in the diagnosis of high-grade splanchnic arterial stenosis or occlusion, Doppler US can be used as a screening method to help detect CA or SMA stenosis or occlusion and can reduce the use of unnecessary, invasive angiography.
确定多普勒超声（US）检测腹腔干（CA）和肠系膜上动脉（SMA）高度狭窄或闭塞的诊断准确性，并验证先前报道的多普勒超声标准。
在最近36个月期间，对82例患者进行了前瞻性研究，无论其有无腹部症状，均采用多普勒超声检查内脏动脉，并进行腹部侧位主动脉造影。所有患者均前瞻性地采用先前报道的空腹收缩期峰值流速测量诊断标准。将多普勒超声检查结果与腹部侧位主动脉造影结果进行比较。
多普勒超声检测CA狭窄或闭塞程度≥70%的敏感性、特异性、阳性预测值、阴性预测值和准确性分别为100%、87%、57%、100%和89%；检测SMA狭窄或闭塞程度≥70%时，这些值分别为100%、98%、93%、100%和99%。
由于多普勒超声在诊断高度内脏动脉狭窄或闭塞方面具有较高的准确性，因此可作为一种筛查方法，有助于检测CA或SMA狭窄或闭塞，并可减少不必要的有创血管造影检查的使用。
