摘要
目的通过对肠系膜上动脉狭窄患者彩色多普勒超声检测肠系膜上动脉(SMA)的各项血流参数的研究,探讨相关参数的变化,为制定肠系膜上动脉闭塞性疾病的超声诊断标准提供资料。方法应用彩色多普勒超声测定26例肠系膜上动脉狭窄患者和50名健康对照组的SMA内径、收缩期峰值流速、舒张末期流速、阻力指数(RI)、加速时间(AT)的数值,并对数据进行组间及组内餐前餐后对比分析。结果狭窄组SMA内径(餐前0.24 cm;餐后0.26 cm)显著小于对照组(餐前0.59 cm;餐后0.62 cm,P<0.05);收缩期峰值流速狭窄组(餐前307.58 cm/s;餐后365.12 cm/s)高于对照组(餐前219.46 cm/s;餐后294.66 cm/s,P<0.05)、舒张末期流速狭窄组(餐前58.31 cm/s;餐后100.63 cm/s)高于对照组(餐前29.68 cm/s;餐后58.23 cm/s,P<0.05)。而2组间RI和AT 2个指标差异无统计学意义(P>0.05)。狭窄组自身餐前、餐后比较,餐后收缩期峰值流速(365.12 cm/s)高于餐前(307.58 cm/s,P<0.05);舒张末期流速餐后(100.63 cm/s)高于餐前(58.31 cm/s,P<0.05),餐后是餐前的1.7倍。结论彩色多普勒超声可作为肠系膜上动脉闭塞性疾病的主要筛查方法,研究结果为制定肠系膜上动脉闭塞性疾病的超声诊断标准提供了资料。
Objective To study the doppler parameters of superior mesenteric artery(SMA) and to provide useful information for developing appropriate diagnostic criteria for SMA occlusive diseases.Methods Twenty-six cases of SMA stenosis group and 50 healthy controls were enrolled the study.Five Doppler parameters were measured under Doppler,including SMA diameter,peak systolic velocity(PSV),end diastolic velocity(EDV),resistance index(RI) and acceler-ation time(AT).The difference between the two groups were compared.Fasting and postprandial changes of the param-eters were also compared among the same group.Results SMA diameter in stenosis group(fasting 0.24 cm,postprandial 0.26 cm) was less than that of the control(fasting 0.59 cm,postprandial 0.62 cm,P0.05).PSV in stenosis group(fasting 307.58 cm/s,postprandial 365.12 cm/s) was higher than that of the control(fasting 219.46 cm/s,postprandial 294.66cm/s,P0.05).EDV in stenosis group(fasting 58.31cm/s,postprandial 100.63 cm/s) was higher than that of the control(fasting 29.68 cm/s,postprandial 58.23 cm/s,P0.05).No significance was found in RI and AT between two groups(P0.05).Postprandial PSV(365.12 cm/s) in stenosis group was higher than fasting(307.58 cm/s,P0.05),postprandial EDV(100.63 cm/s) was higher than fasting EDV(58.31 cm/s,P0.05) in stenosis group.Conclusion Color Dopplerultrasonography can be used as the main screening method for SMA occlusive diseases.And the results provide useful information for developing appropriate diagnostic criteria for SMA occlusive diseases.
