Outcome of percutaneous intervention in iliac artery stents.
OBJECTIVE
To assess the safety and efficacy of secondary procedures in iliac artery stents.


METHODS
Thirty-four patients (36 limbs) underwent one or more interventional procedures in iliac artery stents to treat restenosis (n = 30) or occlusion (n = 6). All patients were followed up by means of clinical and angiographic examination. Primary and secondary patency were assessed with angiography, duplex ultrasound, or both. Primary patency was determined after one interventional procedure, and secondary patency was determined at the end of the study (mean +/- standard deviation, 20.1 months +/- 17.5; range, 1-58 months).


RESULTS
Immediate angiographic success was achieved in all cases. Four complications were observed. The primary and secondary cumulative patency rates were 77.5% +/- 7.6 and 94% +/- 4.1 at 6 months, 73% +/- 8.4 and 89.3% +/- 6 at 12 months, and 51.4% +/- 10.9 and 78.8% +/- 8.8 at 2 years. At the end of the study, 80% of the arteries were still nominally patent.


CONCLUSIONS
Restenosis and chronic occlusion in iliac artery stents can be treated with percutaneous interventional procedures; however, stenosis can still recur.
