Observational study of endoluminal mural thrombotic apposition in popliteal artery aneurysm stenting and its relationship with stent-graft geometrical features.

As shown in Figure 2 , there is no statistically significant correlation between stent diameter and the percentage of EMTS volume or EMTS length, even if a positive trend is observable; that is, EMTS length (as a percentage of the stent length) increases with the stent diameter: this suggests that proximal stents are more prone to thrombus onset and progression because the diameter is larger and unfavorable fluid dynamics conditions are present, as shown in ( 5 ).
