目的探讨经颈动脉超声早期诊断肥胖青少年动脉粥样硬化价值。方法于2006-07在丹东市中学随机抽取47例中、重度单纯性肥胖青少年并与36例正常青少年作对照,分别进行颈部血管超声检查。结果肥胖组动脉内膜呈现不同程度的毛糙、不光滑、连续性差、限局性增厚,颈总动脉内膜中层厚度(IMT)明显高于对照组(P<0.05),肥胖组颈总动脉早期硬化的改变与肥胖程度正相关(P<0.05)。结论青少年单纯性肥胖可以并发动脉粥样硬化,经颈总动脉超声检查可作为早期诊断动脉粥样硬化首选方法。
Objective To investigate the value of carotid artery ultrasound in early diagnosis of atherosclerosis in obese adolescents. Methods Totally 47 cases of moderate and severe simple obesity adolescents were randomly selected from the middle schools of Dandong City in 2006-07 and compared with 36 normal adolescents. The neck vessels were ultrasonographically examined. Results The intimal hyperplasia of the obese group showed varying degrees of roughness, poor continuity and thickening. The intima-media thickness (IMT) of the carotid artery was significantly higher in the obese group than in the control group (P <0.05) The change of sclerosis was positively correlated with the degree of obesity (P <0.05). Conclusion Adolescents with simple obesity can be complicated by atherosclerosis. The common carotid artery ultrasound can be the first choice for early diagnosis of atherosclerosis.
