Purpose:
We compared occlusion of the internal iliac artery (IIA) using coils or the Amplatzer vascular plug (AVP) II prior to endovascular aortic aneurysm repair.
Materials And Methods:
Occlusion of the IIA was performed in 32 patients (aged 74 ± 8 years) using coils (N = 17) or the AVP II (N = 15). We retrospectively compared procedural data, initial success, and clinical outcome in a 12-month follow-up.
Results:
Occlusion was successful in all patients without detection of an endoleak after 12 months. Procedure time and fluoroscopy time for coils versus plugs were 77 ± 35 versus 43 ± 13 minutes and 36 ± 19 versus 18 ± 8 minutes, respectively (P < .003). Incidence of initial buttock claudication (BC) for coils versus plugs was 47% versus 27% and was significantly more severe after coil occlusion (P = .03). After a 12-month follow-up, 2 patients of each group reported of mild BC.
Conclusion:
Occlusion of the IIA is safe and effective using coils or plugs. Initial BC is significantly more severe when coils are used, but after a 12-month follow-up, there is no significant difference. Using a plug is associated with a significant reduction of procedure time and radiation exposure.
