【摘要】 目的比较螺旋CT动脉造影(SCTA)与双功能超声(DUS)诊断血流动力学显著改变的肾血管性高血压(RVH)的可靠性和特异性。方法抽取2009~2015年本院43例临床确诊的RVH患者且同期行SCTA、DUS检测,对比分析2种检测方法的可靠性和特异性。结果 43例患者共检出狭窄血管46根,副肾动脉1根;SCTA的特异性(95.74%)和敏感性(100.00%)均高于DUS的特异性(82.98%)和敏感性(87.23%),差异均有统计学意义(P<0.05);SCTA在狭窄斑块位置、形态、长度、程度、表面状况、负荷及表面溃疡等特征均优于DUS,差异均有统计学意义(P<0.05或0.01),但在斑块结构和重构方面比较,差异均无统计学意义(P>0.05)。结论 SCTA诊断血流动力学显著改变RVH价值的可靠性和特异性均高于DUS。更多还原

【Abstract】 Objective To compare the possibility and characteristic between spiral computed tomography angiography(SCTA) and duplex ultrasonogrphy(DUS) in diagnosing renovascular hypertension(RVH) with obvious hemodynamic changes.Methods Twenty-three cases of clinically diagnosed RVH in our hospital during 2009-2015 were collected and simultaneously performed SCTA and DUS. The reliability and specificity were compared between the two methods. Results In 43 cases,46 narrow blood vessels and 1 accessory renal artery were found. The specificity and sensitivity in SCTA were 95.74 % and 100.00%,which were higher than 82.98% and 87.23% in DUS with statistical difference(P<0.05);SCTA was superior to DUS in determining the characteristics such as the location,shape,length,extent,surface appearance,load and surface ulcer,the differences were statistically significant(P<0.05 or 0.01),while there was no statistical differences in the aspects of density and reconstruction(P>0.05). Conclusion SCTA has higher reliability and higher specificity than DUS in diagnosing RVH with obvious hemodynamic change.更多还原
