Introduction: Literature has it that carotid artery is a window of arteriosclerosis in the whole body and closely related to the occurrence of cardiovascular and cerebrovascular diseases. A research shows that the changes in the morphology and function of the carotid artery are not totally equal. Aims and objectives: The basic aim of the study is to analyze the carotid artery elasticity in patients with SVD by ultrasound data technique. Materials and Methods: This study was conducted in Allied Hospital Faisalabad during July 2019 to December 2019.There were altogether 50 cases, 21 males and 29 females, aging from 38 to 80. The average age was (56.56±8.46). All the patients went through head MRI examination, and the selected cases accorded with neuroimaging diagnostic standards of SVD. The time for ultrasound examination was within one week from the attack. Results: In SVD group, values of SBP, DBP, PP and BMI were higher than the control group, and the difference had statistical significance (P<0.05). There was no significant difference between the two groups in age, FBG, TG, TC, HDL-C and LDL-C (P<0.05). IMT, α, β, and PWV of bilateral carotid artery in SVD group were higher than those in control group; CC was lower than that in control group. Those differences were significant in statistics (p<0.05). Conclusion: It is concluded that there are differences in carotid structural and elastic function in SVD patients. The IMT increased, vascular stiffness increased, PWV increased and blood vessel compliance decreased.
