Peritoneal microcirculation in automated vascular analysis (AVA) analysis. The proportion of perfused vessels (PPV), the perfused vessel density (PVD), and total vessel density (TVD) are determined by AVA software, as shown in this image. The PPV is calculated by scoring all vessels with a flow score greater than 1. PVD can be calculated by multiplying TVD and PPV. Both PVD and TVD are expressed as millimeters per square millimeter. Each score was determined for small microvessels with a cutoff diameter of 25 µm. The red lines show the vessel wall, the yellow lines show the vessel centerline. The numbers on the vessels show the flow within each vessel.
