Analysis of features of carotid artery color doppler ultrasonography in diabetes mellitus patients complicated with cerebral infarction

Abstract

Objective To analyze the changes of carotid artery ultrasound in diabetes mellitus patients complicated with cerebral infarction. Methods From March 2017 to June 2018, 55 type 2 diabetes patients complicated with cerebral infarction in the Second People's Hospital of Yuhang District were selected as study group.Another 50 diabetes patients without cerebral infarction were selected as simple group, and 60 healthy people were selected as control group.The carotid artery colour doppler check was implemented, the carotid artery ultrasound media thickness(IMT) index and carotid plaques were compared in three groups. Results The IMT index in the study group was (1.84±0.23), which was significantly higher than (1.32±0.21) in the control group (t=12.674, P<0.05). The IMT index of the simple group was (1.59±0.19), which was significantly lower than that of the study group (t=6.037, P<0.05). Compared with the control group, the IMT index of the simple group was significantly higher (t=7.009, P<0.05). The detective rate of carotid unstable plaque in the study group was 85.37%(35/41), which was significantly higher than 11.54%(3/26) in the control group (χ2 =21.371, P<0.05). The detective rate of carotid unstable plaque in the simple group was 45.95%(17/37), which was significantly lower than that in the study group (χ2=19.118, P<0.05). The detective rate of carotid unstable plaque between the control group and the simple group had statistically significant difference (χ2=18.342, P<0.05). Conclusion The IMT index of carotid artery in diabetes patients complicated with cerebral infarction is high, and the unstable plaque examination rate is high, which are the risk factors for cerebral infarction in patients with diabetes.To do a good job in carotid atherosclerosis for diabetic patients, and give active treatment, can prevent cerebral infarction.
