Some areas of improvement with respect to the novel endovascular technique exist today. The most relevant aspect, consequently, is the durability of the technique, which depends on the wear and tear of materials and all the systems of implantation. Likewise, the rate of re-intervention is intimately related to the limited durability of the endograft. The present endografts already offer improvements in this sense, which are reflected in materials evermore resistant. Other points to be researched are the behavior of the Type II endoleaks, the so-called endotension: which are the important ones, which ones have to be treated, how to diagnose them and how to prevent them. The cost of the procedure and of the follow-up with instrumental techniques is another element upon which to be improved. The applicability to a greater number of patients will depend, in a large part, on the anatomical limitations for some endografts, thanks to the development of engineering.

All techniques in medicine and surgery are subject to variations and improvements. Endovascular surgery does not escape from these. Because of this, our group finds itself constantly researching and in contact with other international scientific groups, and participating actively in the development of new endovascular products. Proof of this is our group’s organization of the International Symposium of Endovascular Therapeutics, SITE, which takes places every two years in Barcelona. The most eminent experts worldwide assemble at SITE for the discussion and analysis of knowledge on this passionate and revolutionary technique.

Example of technological evolution and technical capacity is the application of endoprosthesis with branches for the visceral arteries. (On the right is a case made by our group).
