Ultrasound Particle Image Velocimetry to Investigate Potential Hemodynamic Causes of Limb Thrombosis After Endovascular Aneurysm Repair With the Anaconda Device

To identify potential hemodynamic predictors for limb thrombosis (LT) following endovascular aneurysm repair with the Anaconda endograft in a patient-specific phantom. A hydraulic piston-driven pump (SuperPump, ViVitro labs, Victoria) was used to set a suprarenal flow profile as inlet boundary condition. In conclusion, these in vitro data show that unfavorable hemodynamics are present in the limb that presented with LT, compared to the non-thrombosed side, with higher VC and longer RT.
