Key result
Restricting IVC flow by ~90% in mice induces thrombi structurally similar to human DVT.
Why the study?
Mechanisms of thrombus formation in veins remain obscure, and a model mimicking flow disturbance as a thrombosis-driving factor is needed to study DVT initiation.
The murine IVC stenosis model effectively mimics human DVT, providing a reproducible method to study thrombosis mechanisms and test preventive strategies.

Establishes murine IVC stenosis as a reproducible DVT model; leaves open translation to human prevention strategies.
Payne et al. (2017) studied Deep vein thrombosis. Partial flow restriction (stenosis) in the inferior vena cava was evaluated on Development of thrombi structurally similar to those in humans. Partial flow restriction closing ~90% of the inferior vena cava lumen for 48 hours in mice induces thrombi structurally similar to human DVT, though 0-35% of mice may not form a thrombus.
