OBJECTIVE: To evaluate the impact of pre-emptive embolization of inferior mesenteric and lumbar arteries on the incidence of type II endoleak and aneurysm sac dimensions after EVAR.
MATERIAL AND METHODS: A retrospective single-center cohort study included 145 patients who underwent EVAR between 2023 and 2025. Patients were divided into two groups: with pre-emptive embolization (n=32) and without this procedure (n=113). Follow-up CT angiography was performed after 12 months. Primary endpoint was the incidence of type II endoleak; secondary endpoints included changes in maximal aneurysm diameter and infrarenal aortic volume.
RESULTS: After 12 months, type II endoleak was observed in 3.1% and 17.7% of cases, respectively (p=0.045). Aneurysm sac growth occurred in 6.3% and 15.9% of patients, respectively (p=0.246). Embolization procedures were associated with longer surgery time, increased fluoroscopy duration and greater contrast volume.
CONCLUSION: Pre-emptive embolization of inferior mesenteric and lumbar arteries in EVAR reduces the incidence of type II endoleak and shows a trend towards less aneurysm sac growth despite higher technical complexity and contrast volume.
