ResumoThe aim of the current study was to evaluate the resistivity index (RI) and pulsatility index (PI) of hepatic artery (HA) by Triplex Doppler in health adult dogs on pre and postprandial periods. The experimental group was formed by 14 mongrel dogs, 9 females and five males, weighing 6-19 kg and 4-16 kg, respectively. The animals were previously prepared, remaining 24 hours of starvation, and feeding with milk or pellet show food to perform posprandial analysis. The ultrasound PHILIPS HDI 4000 equipped with a micro convex transducer (5-8MHz) was used. The RI and PI measurements of HA were performed on tree times: T0 (pre-prandial period), T1 (30 minutes postprandial) and T2 (90 minutes postprandial). There are no statistical differences between T0 and T2 when compared RI and PI of HA. However, both indices were significantly diminished on T1 in relation with T0 and T2, which represents an increase of AH blood flow 30 min postprandial. The employment of HA Triplex Doppler improves the blood flow evaluation pre and posprandial and can be one important technique to establish comparative parameter to distinguish between hepatic metabolic homeostasis from different physiopathologics states.
