AI Article Synopsis
- The study evaluates the efficacy of two approaches to treat type II endoleaks in patients who underwent endovascular repair of abdominal aortic aneurysms: embolization of the endoleak nidus only versus embolization of both the endoleak nidus and branch vessels.
- Out of 29 patients analyzed, both treatment methods showed similar outcomes in reducing endoleaks and stabilizing aneurysm size, but the dual approach required significantly longer procedure times and resulted in increased radiation exposure.
- Overall, there was no advantage found in the more complex embolization strategy, suggesting that simpler methods may be just as effective for patient outcomes.
Article Abstract
Purpose: To compare outcomes of type II endoleak embolization involving embolization of the endoleak nidus only vs embolization of the endoleak nidus and branch vessels in patients treated with endovascular repair of abdominal aortic aneurysms.
Materials And Methods: Twenty-nine consecutive patients (mean age, 77.9 y; range, 63-88 y) with type II endoleak who underwent embolization from 2004 to 2015 were retrospectively reviewed. Patients were divided into 2 groups: embolization of endoleak nidus only (group A) and embolization of endoleak nidus and branch vessels (group B). Mean follow-up intervals were 20.5 months ± 14.7 in group A and 24.3 months ± 18.5 in group B. Outcomes were compared between groups by Mann-Whitney U and Pearson χ tests.
Results: Mean interval from endovascular aneurysm repair to embolization was 47.6 months ± 42.9, and mean presentation time of endoleak before embolization was 23.1 months ± 25.8. Coils (n = 28) and liquid embolic agents (n = 23) were used for embolization. There were no significant differences in rates of residual endoleak (50% vs 53.8%; P = .96) or sac decrease/stabilization (62.5% vs 61.5%; P = .64). Procedure time and radiation exposure in group B (132.3 min ± 78.1; 232.4 Gy·cm ± 130.7) were greater than in group A (63.4 min ± 11.9; 61.5 Gy·cm ± 35.5; P < .01). There were no procedure-related complications.
Conclusions: Embolization of the endoleak nidus and branch vessels is not superior to embolization of only the nidus in terms of occlusion of type II endoleak and change in sac size despite requiring longer procedure times and resulting in greater patient radiation exposure.

Objectives: Embolizing an abdominal aortic aneurysm sac through a transcaval approach is a novel approach to treat type-II endoleaks that occur following aortic endografting. This study reviews the outcomes of this treatment in one of the few centres in Australia that offers this procedure.
Methods: A retrospective cohort study was conducted, including patients who had received transcaval embolisation of type-II endoleak over a 9-year period.

Background: Current guidelines recommend preserving at least one of the bilateral pelvic flows in patients with aortoiliac aneurysms. The sandwich parallel graft, using commercially available devices, provides a viable option for patients who fall outside the instructions for use of iliac branch devices. However, gutter endoleak remains a significant challenge.

The purpose of this study is to evaluate the feasibility and clinical outcomes of vasa vasorum embolization for preventing continuous aneurysmal expansion after endovascular aneurysm repair (EVAR). We retrospectively reviewed the medical records of patients who underwent vasa vasorum embolization between August 2018 and May 2022. Vasa vasorum embolization was attempted in cases of continuous aneurysmal expansion after EVAR, where the vasa vasorum was identified through catheter angiography.

Type II endoleaks after endovascular aortic repair are a common scenario that, although infrequently, may sometimes require secondary interventions when leading to significant enlargement of the aneurysm sac. Herein, we present the perioperative and mid-term results of one of our endovascular aortic repair cases with type II endoleak from the hypogastric artery, whose ostium was covered by the prior stent graft limbs and that were successfully treated with a novel technique employing re-entry catheters in an off-label fashion. This technique may represent a valid alternative solution when conventional access between artery and prosthesis is laborious or impossible to achieve.
