OBJECTIVE: A type 2 endoleak (T2EL) is the most frequently occurring endoleak type after endovascular aneurysm repair (EVAR). Residual T2ELs may cause aneurysm rupture; however, the management of a T2EL remains controversial. This study evaluated sac branch preemptive embolization using N-butyl-2-cyanoacrylate, aiming to prevent T2ELs and sac shrinkage.
METHODS: Twelve consecutive patients underwent elective preemptive embolization during EVAR at our hospital between August 2018 to March 2019. Their demographic information, operative details, and sac diameters were examined at 6 months after EVAR.
RESULTS: No procedural complications were observed. There were no in-hospital deaths among the 12 patients. Sac shrinkage was observed in this cohort (53.8-52.1 mm, p = 0.01). A total of 33 lumbar arteries were occluded with this procedure, and 2 patients had residual T2ELs at 6 months.
CONCLUSIONS: A T2EL in preemptive sac branch embolization during EVAR has advantages in terms of safety and reduction. Although no clear evidence is available for the management of T2ELs, this study proposes a new standard to prevent it and improve the long-term outcomes after EVAR. However, embolization remains imperfect and further research is necessary.
