Type 2 Endoleak Hybrid Repair with Open Approach and Endovascular Angioembolization on a 10 Centimeters Aortoiliac Aneurysm: Case Report and Literature Review

Abstract

Type 2 endoleak after endovascular aneurysm repair of abdominal aortic aneurysms remains the most prevalent type of endoleak. Depending on the time of appearance, can be classified as primary, or secondary, those that appear after the first month after endoprosthesis implantation. Type II endoleaks, due to retrograde filling of the aneurysmal sac from a collateral artery, constitute the most frequent subgroup. Most of the type II endoleaks resolve spontaneously. Which is why they must be treated. The surgical treatment of type 2 endoleaks is through a transarterial approach, In this case, This technique is complicated even in expert hands, and migration of the coils proximally or distally is not uncommon. In general, EVAR is associated, for the moment, with a non-negligible risk of other postoperative complications, such as ischemic complications, those associated with rupture or mobilization of the endoprosthesis, and endoleaks. These complications can affect up to 35% Of the patients who undergo EVAR compared to 8% After CAC. Of cases, and in addition, in the long-term evolution, failures may occur due to material fatigue, with it, the pressurization of the sac and eventually the evolution towards rupture. Follow-up is something inherent to EVAR.
