Introduction:
Considering the importance of health, the effect of obesity on the quality of life, the person's self-image, and the effect of obesity on various organs, especially the vessels, and the absence or presence of a study in Iran that investigated the effect of gastric bariatric surgery on the diameter of the femoral vein, in the present study, we investigated the effect of bariatric surgery on femoral vein diameter in morbidly obese patients referred to Imam Hossein hospital.
Materials And Methods:
The present study was a prospective cohort study on morbidly obese patients referred to the center in 2022-2023. In this study, 31 morbidly obese patients with BMI above 30 kg/m2 who were candidates for bariatric surgery were examined. Demographic data were collected using a demographic profile checklist. BMI, the diameter of common femoral veins, and the great saphenous vein were measured and recorded before and 6 months after surgery. Ultimately, the data was collected and analyzed using SPSS V.24 software.
Results:
In the current study, 31 patients (62 extremities) were examined. The mean age of the patients was 34.45, with a standard deviation of 8.86. Fourteen patients (45.2%) were male, and 17 (54.8%) were female. The mean diameter of the common femoral vein in the 6 months after surgery was significantly less than before surgery (11.58 (1.64) compared to 12.95 (1.84), P = 0.0001). The mean diameter of the great saphenous vein in the 6 months after surgery was significantly less than before surgery (7.30 (1.45) compared to 7.75 (1.45), P = 0.0001).
Conclusion:
It seems that bariatric surgery causes a significant decrease in the diameter of lower limb veins (common femoral vein and great saphenous vein) compared to before surgery. However, further studies in this field are recommended.
