Abstract
- Background and purpose: Computational fluid dynamics method (CFDM) and optical flow method (OFM) effec- tively provide the hemodynamic information based on the digital subtraction angiogram (DSA). However, the quantitative analysis in comparison of CFDM and OFM is still absent. The goal of this study is to apply CFDM and OFM in quantitative analysis of stenting treatment. Material and method: A left carotid stenosis patient underwent stenting of percutaneous transluminal angioplasty was ana- lyzed as an example. CFDM and OFM for hemodynamic analysis on digital subtraction angiography before and after stenting treatment were presented. Results: Improvement gains of blood flow velocities on left internal carotid artery after stenting treament for different initial conditions on the common carotid artery were 1.91∼2.13, 1.62∼2.09, and 0.69 by CFDM with Newtonian and non-Newtonian fluids and OFM, respectively. With the CFDM analysis, the flow mapping by OFM using time resolved DSA data on the fl yt o estimate hemodynamic significance of a cervical carotid stenosis was explained. Conclusion: Quantificative blood flow estimations by CFDM and OFM to evaluate the treatment outcomes to patient with carotid stenosis are practical. Both methods are able to provide quantitative information of blood flow for stenting treatment. It is advantagious to use both methods in treatment evaluation.
