Temporal evolution of hemodynamics in murine arteriovenous fistula: A micro-CT based CFD study
Fig 2
Contrast-enhanced CT images and segmented vascular structure.
(a) CT images in three orientations, coronal, sagittal, and axial, near the AVF. A volume rendering of the CT images is shown in the upper right to visualize vasculature and bone structure. The AVF and surrounding veins and arteries are annotated in yellow. (b) and (c) Segmented vasculature near the AVF at day 7 and day 21 post-surgery, respectively. Color coding represents distinct vessel segments: red indicates the carotid artery (with the proximal segment at bottom and distal segment at top), yellow highlights the AVF region (4 mm of length), and blue shows the main venous drainage with its characteristic ballooning of the vein starting 4 mm from the anastomosis.
