PURPOSE
The techniques mostly used for the diagnosis of superior mesenteric artery (SMA) stenosis are computed tomography angiography (CTA), and magnetic resonance angiography. We aimed to evaluate color-coded Doppler Ultrasonography (CDUS) for the detection of SMA stenoses and to determine Doppler criteria.
METHODS
We identified retrospectively 65 patients with CTA images of SMA stenosis and examined them with CDUS for the Doppler measurement of SMA peak systolic flow velocity (PSV), end-diastolic velocity (EDV), and mesenterico-aortic ratio (MAR). Results were analyzed with receiver-operating characteristic curve analysis.
RESULTS
The optimal threshold values for determining 50%-69% SMA stenoses were PSV >280 cm/s, EDV >45 cm/s, and MAR >3.6. For identifying 70%-99% SMA stenoses, they were PSV >395 cm/s, EDV >74 cm/s, and MAR >3.6.
CONCLUSION
CDUS is a convenient method with high accuracy for identifying SMA stenosis. PSV yielded better results than EDV and MAR.
目的
诊断肠系膜上动脉（SMA）狭窄最常用的技术是计算机断层血管造影（CTA）和磁共振血管造影。我们旨在评估彩色编码多普勒超声（CDUS）对SMA狭窄的检测能力，并确定多普勒标准。
方法
我们回顾性地确定了65例有SMA狭窄CTA图像的患者，并对他们进行CDUS检查，以测量SMA的收缩期峰值流速（PSV）、舒张末期流速（EDV）和肠系膜-主动脉比率（MAR）。结果采用受试者工作特征曲线分析。
结果
确定50%-69%的SMA狭窄的最佳阈值为PSV>280 cm/s、EDV>45 cm/s和MAR>3.6。对于识别70%-99%的SMA狭窄，阈值为PSV>395 cm/s、EDV>74 cm/s和MAR>3.6。
结论
CDUS是一种方便且准确性高的识别SMA狭窄的方法。PSV的结果优于EDV和MAR。
