OBJECTIVES: to evaluate the long-term results of stenting in iliac and aortic occlusive disease and identify factors predicting clinical outcome.
DESIGN: retrospective study.
MATERIALS AND METHODS: 82 patients (87 limbs) with stenoses (n =63) and occlusions (n =24) in the aortoiliac segment were treated with stents. 81 lesions involved the iliac arteries, 3 the infrarenal aorta and 3 the aortic bifurcation. Primary stenting was performed in 57 limbs (complex stenotic lesions and occlusions). Stents were placed following failed PTA in 30 limbs. Median follow-up was 13.2 months (1-66 months).
RESULTS: technical success was 99% and clinical success 89%. Cumulative primary and secondary patency of stented iliac atherosclerotic lesions at 1 and 3 years was 75 and 61%, and 83 and 75% respectively. The factors predicting outcome of primary patency identified in Cox multivariate analysis were ankle-brachial index (ABI) prior stenting (p =0.03) and length of the lesion (p =0. 007). Major non-fatal complications occurred in 7.4% of the patients and there were no deaths attributed to the treatment. The 30-day mortality was 3.7%.
CONCLUSION: stenting of complex aortoiliac stenoses and chronic occlusions is a safe and effective treatment modality. Long lesions and lower pre-procedure ABIs were found to negatively influence outcome.
