Key result
Computational flow analyses of a patient with Type-B aortic dissection showed that blood pressure reduction lowers wall shear stress and occluding all re-entries is needed to induce thrombosis.

May aid endovascular planning in Type-B dissection; leaves open prospective validation of re-entry occlusion.
How do best medical treatment and different endovascular repair scenarios affect hemodynamic features in Type-B aortic dissection?
Computational fluid dynamics can model hemodynamic changes in aortic dissection and may assist in planning endovascular stent-graft procedures by identifying critical re-entries.
Chen et al. (2013) studied Type-B aortic dissection (n=1). Computational fluid dynamics modeling of best medical treatment and endovascular repair scenarios vs. Initial presentation was evaluated on Hemodynamic features including pressure, wall shear stress, and inter-luminal flow exchange. Computational flow analyses of a patient with Type-B aortic dissection showed that blood pressure reduction lowers wall shear stress and occluding all re-entries is needed to induce thrombosis.
