Echocolor Doppler of the celiac trunk, mesenteric arteries and renal arteries: How To Do It and Normal Findings. (updated)

The study of the celiac trunk, of the mesenteric and renal arteries should preferably be performed early in the morning, with a low frequency convex probe (3.5-5 MHz). In these cases, B-mode is only aimed at positioning the sample volume of the pulsed Doppler as these arteries are deep, frequently with poor echo imaging.
The study of the celiac trunk and mesenteric arteries is performed in anterior projection (longitudinal and transverse scans). While the normal celiac trunk has a "low resistance" flow, with a wide diastolic component, mesenteric arteries present a high-resistance flow.
The extrarenal arteries are studied in anterior and lateral projections. While the right renal artery is more ventral, the left renal artery is more posterior, parallel to the left renal vein. The intrarenal arteries are explored in lateral and posterior projections. The spectral analysis of renal arteries is characterized by a systolic peak, a large diastolic component and no spectral dispersion (laminar flow).
In this lesson the methodology of the echocolor Doppler study of the celiac trunk, mesenteric and renal arteries is presented.
