Figure 5. Drawing illustrating the parallel stent graft technique to stop retrograde flow in the thoracic false lumen from residual intimal
tears in the suprarenal and subrenal aorta (black arrows). Three stent grafts are positioned from the origin of the left subclavian artery
to the aortic bifurcation. The visceral stent of the celiac trunk and the superior mesenteric artery are positioned between the first and
second aortic stent grafts; instead, the stents of renal arteries are located between the second and third aortic stent grafts. All visceral
are incannulated and stented with the anterograde approach from the top.

above-mentioned techniques. In conclusion, endovascular strategies to promote FL thrombosis after
TEVAR in aortic dissection showed good early results with minimal invasiveness, offering different
alternative depending on the anatomy and the level of urgency. In any case, in consideration of the
complexity of the problem, each of these strategies should be used with caution and more long-term studies
and prospective and randomized clinical trials are needed to provide solid evidence on this topic.
