2型糖尿病患者颈动脉病变与肠系膜上动脉病变的相关性分析

目的探讨2型糖尿病患者颈动脉病变与肠系膜上动脉病变的相关性，旨在提高对2型糖尿病患者并发肠缺血的认识。方法应用彩色多普勒超声对2型糖尿病患者（63例）及健康成人（50例）行颈动脉及肠系膜上动脉检查，彩色多普勒超声检查其颈动脉病变与肠系膜上动脉病变，测量血管的搏动指数、阻力指数，并分析两支血管的相关性。结果63例糖尿病患者中，41例存在颈动脉病变，36例存在肠系膜上动脉病变，糖尿病组41例颈动脉病变患者中，33例同时伴有肠系膜上动脉病变。糖尿病组颈动脉病变与肠系膜上动脉病变存在80％重合现象。糖尿病组颈动脉、肠系膜上动脉的搏动指数、阻力指数均较对照组减小（P〈0．05），且两支血管存在显著相关性（r=0．085）结论糖尿病不仅是造成头颈部动脉病变的重要危险因素，也同样是腹腔主要供血动脉-肠系膜上动脉病变发病危险因素之一．两者乡间存存显薯相姜忡．

Correlation study of carotid artery and superior mesenteric artery disease in patients with type 2 diabetes

Objective To explore the correlation of carotid artery and mesenteric artery disease in patients with type 2 diabetes, and to improve the acknowledge of intestinal ischemia in patients with type 2 diabetes. Methods The carotid artery and superior mesenteric artery of patients with type 2 diabetes （ 63 cases） and healthy subjects （ 50 cases ） were examined by color Doppler ultrasound,then the PI and RI was measured, and the relationship between carotid artery disease in diabetes and superior mesenterlc artery disease was analyzed. Results In 63 cases of diabetes, there were 41 cases of carotid artery disease,36 cases of superior mesenteric artery disease. In 41 cases of diabetic patients with carotid artery disease ,there were 33 cases accompanied with superior mesenteric artery lesions, carotid artery and mesenteric artery disease in diabetic group has 80% overlap phenomenon. The PI and RI of carotid artery and superior mesenteric artery in diabetic group were less than those in control group （ P 〈 0.05 ）, and there was significant correlation between two blood vessels （ r = 0. 085 ）. Conclusion Diabetes is not only important risk factor of head and carotid artery disease, but also is risk factor of the main abdominal artery - superior mesenteric artery disease,there is significant correlation correlation between carotid artery and superior mesenteric artery disease.
