- 2E33 Study of relationship between the impingement flow and activation of thrombogenic factors using whole blood in micro-channels
抄録
Relationships between impingement of blood flow and thrombus formation mechanisms in human arteries are still hypothetical. This study investigated the relationship between different conditions of impingement and thrombus formations. Impingements of whole blood were created using Y-shaped and T-shaped micro-channels that were MPC coated. The velocities of impingement were set to be 0.2 m/s and 3.0 m/s. The whole blood was obtained from a healthy male volunteer. The whole blood at the impingement area was observed with an inverted microscope and a high-speed camera. Also, areas of thrombus ware measured on the obtained images using Image-Pro Plus to quantify the thrombus volume. The results showed that thrombus formation occurred in the Y-shaped impingement flow and didn't occur in the T-shaped impingement flow in either of the velocity. The thrombus formation in the Y-shaped impingement at low velocity occurred at the position shifted to the right and left rear from the bifurcation center. The thrombus formation at high velocity occurred at the bifurcation center. In addition, thrombus at low velocity peeled off easily than at high velocity. In conclusion, it was suggested that different impingement patterns affect the formation, formation point, and detachment rate of thrombus in the micro-channels.
