  1. Dimensions and volume fill were determined from 3D renderings of the individual thrombi done in Amira software. The unfilled central cavity is continuous with the vault volume present in the intravascular thrombi crown found 5 min post-puncture. Cavity dimensions decrease with time. SD standard deviation. P values were calculated using the Student t-test for either paired data or unpaired data with unequal variance. Calculated P values point to a significant variance in central cavity diameter versus puncture hole diameter, i.e., a numerical indicator of a progressive, localized accumulation of platelets inward from the exposed puncture hole adventitia.
