Outcome and clinical significance of delayed endoleaks after endovascular aneurysm repair

Abstract: This long-term outcome study demonstrated that delayed endoleaks appearing >1 year after EVAR contributed to most of the overall endoleaks and were significantly associated with aneurysm sac growth. This study underscores that type II endoleak is not benign and that vigilant lifelong surveillance after EVAR is critical.

“…Endoleak, graft migration, and aneurysm sac enlargement constitute the remaining shortcomings of endovascular aneurysm repair and underlie the observed loss of comparative clinical benefit during long-term follow-up. [3][4][5][6] The Nellix device (Endologix, Irvine, Calif) was developed with recognition that many of the complications of endovascular aortic aneurysm repair stem from inadequate isolation of the native aortic wall from pressurized blood flow. The highly differentiated Nellix platform uses polymer-filled polyurethane EndoBags surrounding balloon-expandable stents covered with expanded polytetrafluoroethylene and stabilizes the aneurysm sac by completely filling and sealing the blood flow lumen, hence the name EndoVascular Aneurysm Sealing (EVAS) system.…”

“…9 Although a consensus has been reached on the management of type I and type III ELs, the management of T2EL remains a controversial subject without clear-cut guidelines, so that decision-making is totally up to the surgeon's and patient's preferences. 4 The incidence rate of T2EL was reported to be between 16% and 34%, 4,5,7,10 and T2EL vessels often stop flowing spontaneously. 4,5 However, some T2ELs might result in enlargement or rupture of aneurysms, and persistent T2ELs are associated with late adverse outcomes.…”

“…La mayor limitación de esta técnica es la necesidad de seguimiento a largo plazo mediante técnicas de imagen debido a la alta tasa de complicaciones tardías que presenta, principalmente se trata de endofugas, migraciones de prótesis, ruptura de prótesis o trombosis intraprotésica. Las endofugas son las más frecuente (17% aproximadamente) y pueden ser de 5 tipos diferentes (2,5,6,7); en nuestro caso el paciente sufrió tres tipos diferentes de éstas durante 9 años de seguimiento tras la intervención. La mayoría de estas complicaciones, sobretodo aumento del saco aneurismático por porosidad de la prótesis o migración de ésta, se han descrito con prótesis de primera generación como Excluder® de Gore o Talent® de Medtronic (en nuestro paciente se colocó esta endoprótesis), siendo menos frecuentes en las prótesis de segunda generación actuales (1).…”
