代谢综合征患者颈动脉与肠系膜上动脉病变的相关性研究

目的 探讨代谢综合征（MS）患者颈动脉与肠系膜上动脉（SMA）病变的相关性研究.方法 应用彩色多普勒超声对72例MS患者（MS组）及70例健康体检者（对照组）同时作颈动脉和SMA检查,检测两支动脉血管壁病变及颈总动脉内-中膜厚度（IMT）、收缩期峰值速度（PSV）、舒张末期速度（EDV）、搏动指数（PI）、阻力指数（RI）,以研究两支动脉血管病变的相关性.结果 72例MS患者中,48例存在颈动脉病变,39例存在SMA病变,38例同时伴有两处病变,颈动脉病变与SMA病变存在79.2%重合现象.MS组颈总动脉和SMA的PI、RI均较对照组减慢（P〈0.05）,MS组颈动脉PSV、ESV均较对照组减低,SMA的PSV、ESV则均较对照组加快（P〈0.05）,且两支血管间各参数指标存在显著相关性（r=0.804）.结论 MS患者易发生头颈部动脉病变,同样也可以引起腹腔主要供血动脉如SMA发生相应病变,而且两支动脉血管病变之间存在显著相关性.

Correlation study of carotid artery and superior mesenteric artery disease in patients with metabolic syndrome

Objective To explore the correlation of carotid artery and superior mesenteric artery （SMA） disease in patients with metabolic syndrome （MS）. Methods The carotid artery and SMA of patients with MS and healthy subjects （ control group） were examined by color Doppler ultrasound,then the arteries wall diseases, intima-media thickness（ IMT）, systolic peak velocity （PSV）, end-diastolic velocity （EDV）, Pulsatility index（PI） and resistance index（RI） of common carotid artery were detected, and the relationship between carotid artery disease and SMA disease was analyzed. Results In 72 cases, there were 48 cases of carotid artery disease,39 cases of SMA disease, 38 of them were accompanied with carotid artery and SMA lesions （79. 21% ,38/48）. Compared with control group, the PI and RI of carotid artery and SMA in MS group were decreased（P〈 0.05 ）, the PSV and EDV of carotid artery were decreased, the PSV and EDV of SMA were increased（ P〈0. 05 ）, there was significant correlation between two blood vessels （ r = 0. 804 ）. Conclusion MS is not only important risk factor of head and carotid artery disease,but also is risk factor of the main abdominal artery SMA disease, there is significant correlation between carotid artery and SMA disease.
