Key result
Balloon-assisted transcaval embolization proves feasible for post-EVAR type II endoleak and aortocaval fistula.
Why the study?
Type II endoleak associated with persistent aneurysmal sac growth after endovascular aortic repair is an adverse event requiring endoleak occlusion.
Case Report (n=1)
Balloon-assisted transcaval embolization using coils and Onyx is a feasible approach for treating type II endoleaks associated with aortocaval fistulas after EVAR.
Supports embolization feasibility in type II endoleak with aortocaval fistula; leaves open validation in larger cohorts.
Endovascular aortic repair is an accepted treatment option for patients with infrarenal aortic aneurysm. Type II endoleak associated with persistent aneurysmal sac growth is considered an adverse event requiring endoleak occlusion. We describe the case of a patient with type II endoleak after endovascular aortic repair for infrarenal aortic aneurysm associated with aortocaval fistula and persistent aneurysm growth. Type II endoleak embolization was successfully performed with coils and Onyx through a transcaval approach using an occlusion balloon and co-axial microcatheter.

Boodt et al. (2020) conducted a case report in Type II endoleak associated with an aortocaval fistula after endovascular aortic repair (n=1). Balloon-assisted transcaval embolization with coils and Onyx was evaluated on Embolization success. Balloon-assisted transcaval embolization using coils and Onyx was successfully performed in a patient with a type II endoleak and aortocaval fistula after endovascular aortic repair.
