Brief Review of Recent Study on Fluid–Structure Interaction Modeling of Blood Flow in Peripheral Arterial Disease

Peripheral artery disease (PAD) is an atherosclerosis event in which the peripheral arterial walls become thickened and hardened due to the buildup of the plaque. The condition causes restriction to the blood flow and increase the risk of vascular disorders such as gangrene and heart attack. Fluid–structure interaction (FSI) modeling can be used to diagnose and understand the PAD by virtually simulating the blood flow and the arterial wall. This article presents a brief systematic review on the recent study of FSI in PAD from 2015 to 2022 to identify the latest FSI methods, findings, and trends. By using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) procedure, a total of 158 related FSI articles from the main databases, i.e., Scopus, PubMed, and ScienceDirect, were screened thoroughly, and only three articles reported the FSI in stenosed PAD. The findings are categorized into geometry construction, analysis method, blood viscosity model, and wall characteristic. This study may provide systematic information to future research in producing better outcome of fluid–structure interaction in PAD and other stenosed arteries.
