Effects of fatty and carbohydrate meals on superior mesenteric artery by color doppler ultrasonography

Introduction: Duplex ultrasound (DU) provides a simple, portable, reproducible, and non-invasive assessment of blood flow. Measurement of luminal diameter and blood velocity allows estimation of blood flow and peripheral resistance and the detection of arterial occlusive disease. Owing to its size and anatomic position, the superior mesenteric artery (SMA) is also accessible to DU. Applied to the superior mesenteric artery; the method confirms that blood flow in this vessel increases in response to a meal. Objective: To investigate the contribution of the different types of meals to blood flow of the Superior Mesenteric Artery (SMA) by Doppler ultrasonography as a means of determining the relative potencies of the major nutrient stimuli in healthy human subjects. Materials and Methods: One hundred healthy volunteers , with age variation (20 -50) years, were examined before and after different two meals type that include varying Kcals and contents (250 gram, 545 Kcal and 270 gram, 477 Kcal) in order to assess (SMA) , diameter DM and blood flow volume BFV. Results: The peak values of DM and BFV for the fatty, and carbohydrate meal appear at 60 min, and 30 min respectively, after meal taken up to 90 min. There was significant value for the correlation between the varying time with the mean values of DM, and BFV of SMA for fatty and carbohydrate meal. Conclusion: The fatty compared to carbohydrate meal take long time for SMA response songraphically.
