Iliac Vein Aneurysms: A Comprehensive Review

Abstract

main body by 20cm in the DB model. Accordingly, the iliac limbs of the DB model presented a 9mm stenosis over a 30mm-segmental length in the mid-portion of the limbs. The displacement forces were estimated during a cardiac cycle at three segments (main-body, bifurcation and iliac limbs) of both models with Computational Fluid Dynamics analysis. Results-The DB accommodation was associated with higher forces at the main-body (range 3.15-4.9N) compared to the classic configuration (1.56-2.34N). On the contrary, the forces at the bifurcation (3.81-5.98N vs. 3.76-5.54N) as well as at the iliac limbs (0.34-0.85N vs. 0.49-0.74N) were comparable for both models (Figure 1). Conclusion-The DB accommodation seems to correlate with higher displacement forces at the main-body of aortic endografts compared to the classic bifurcated design. Consequently, regular imaging follow-up of the DB design deems necessary to delineate its mid-and long-term hemodynamic and clinical performance.
