M. Echenagusia Boyra, G. Rodriguez Rosales, M. González Leyte, A. Alvarez Luque, C. BALLANO FRANCO, L. reparaz; Madrid/ES

Aims and objectives:
To evaluate the safety and efficacy of the Amplatzer vascular plug (AVP) for embolization of common iliac arteries during aorto-uni-iliac endovascular aortic aneurysm repair (EVAR).
Methods and materials:
Between December 2010 and October 2017 twenty-three consecutive patients (22 men, 1 woman; mean age 74-years-old, 48-83 years) underwent occlusion of the common iliac artery (CIA) with a vascular plug during EVAR. These patients were treated with an aorto-uni-iliac graft, femoro-femoral by-pass and [...]
Results:
CIA occlusion was successful in all 23 patients. A total of 26 type 2 AVPs were deployed (three patients required 2 devices). No other embolic agents were used. Complete and precise occlusion was confirmed angiographically in all patients. The average diameter of the occluded CIA was 12,7 mm ([...]
Conclusion:
The Amplatzer vascular plug is safe and effective for common iliac artery occlusion during EVAR.
