Hemodynamic Characteristics of Peripheral Arterial Disease Using Computational Fluid Dynamics

Sponsor: Fudan University

View on ClinicalTrials.gov

Summary

Peripheral arterial disease can reduce blood flow to the legs. This study will examine how blood flow patterns in the leg arteries differ between people with peripheral arterial disease and people without the disease. Researchers will use existing computed tomography angiography (CTA) images and medical records from participants who previously received CTA as part of routine clinical care. Three-dimensional models of the leg arteries will be created from these images. Computer simulations will then be used to study how changes in blood flow entering the arteries and resistance in smaller downstream blood vessels affect blood flow patterns. The researchers will compare these responses between participants with and without peripheral arterial disease. This study uses only existing medical records and images. No new participants will be recruited, and no additional examinations or treatments will be performed for research purposes. The goal is to better understand blood flow characteristics associated with peripheral arterial disease.

Computational Fluid Dynamics Simulation

Patient-specific three-dimensional lower-extremity arterial models will be reconstructed from existing CTA images and analyzed using computational fluid dynamics (CFD). Two independent single-factor simulation experiments will be performed: an inlet velocity experiment, in which the amplitude of the inlet pulsatile velocity waveform is varied while distal peripheral resistance is held constant, and a peripheral resistance experiment, in which distal peripheral resistance is varied while inlet velocity is held constant. These simulations are performed only on computational models and do not involve any clinical intervention, additional examination, or treatment of participants.
