Endovascular management performed percutaneously of isolated iliac artery aneurysms.
OBJECTIVE
To report about the endovascular treatment of isolated iliac artery aneurysms (IIAA) with stentgraft placement and transluminal or CT-guided embolization of the internal iliac artery or the combination of these methods.


METHODS
Over a period of 5.6 years, 36 interventions were performed in 20 patients with 23 IIAAs. In a retrospective analysis patient records were reviewed. The CT-angiography follow-up was evaluated for the presence of re-perfusion of the IIAA and for change of aneurysm diameter.


RESULTS
Primary success was achieved in 15/23 aneurysms (65%), and secondary success in 21/23 aneurysms (91%). In 5/23 cases two interventions and in 1/23 cases three interventions were necessary to achieve secondary success. Embolization alone, as a therapy for aneurysms involving only the internal iliac artery, had a success rate of 27%. No procedure-related minor or major complications occurred. Mean decrease of aneurysm size during a mean observation period of 14.1 months was 6.9% which was not significant (p=0.3; 95% confidence interval +7-21%).


CONCLUSIONS
Endovascular therapy of isolated iliac artery aneurysms performed percutaneously has become a treatment alternative to open surgical repair. This method is feasible and safe with low procedure-related morbidity and mortality. However, on average more than one intervention has to be performed to achieve successful permanent exclusion of the aneurysm and embolization alone in isolated internal iliac artery aneurysms is not sufficient.
