Abstract
Purpose
Although it is well known that obesity increases the risk of atherosclerosis in carotid arteries, it is not clear whether this risk changes after obesity surgery. The aim of this study was to investigate whether weight reduction with a laparoscopic sleeve gastrectomy (LSG) has any effect on distensibility and elasticity which show subclinical atherosclerosis in the carotid arteries of obese individuals.
Materials and Methods
This prospective study included 130 patients (body mass index (BMI) 48.21 ± 6.97 kg/m2) who underwent LSG. The patients were followed up for 1 year. Comparisons were made of the distensibiliy and elasticity values calculated preoperatively and at 1, 3, 6, and 12 months, postoperatively.
Results
There was a statistically significant increase in distensibility and elasticity values from baseline to 1, 3, 6, and 12 months postoperatively (p < 0.001 for both comparisons). The multiple linear regression analysis was used to find the variables affecting both distensibility and elasticity. According to the results, the presence of BMI decreases distensibility percentage change level by 0.38 units (β= − 0.38, 95% CI − 0.51;− 0.25, p < 0.001). The presence of fasting plasma glucose decreases elasticity percentage change level by 0.20 units. (β= − 0.20, 95% CI − 0.39; − 0.01, p = 0.037).
Conclusion
Carotid artery distensibility and elasticity values increase after LSG, and this change could be caused by the change in metabolic parameters and heart geometry. These results may indirectly suggest that subclinical atherosclerosis in carotid arteries has decreased after obesity surgery.
