Abstract:
PURPOSE:To evaluate the long-term success of tantalum stents implanted in iliac artery lesions and to determine potential predictive factors of early and late stent failure. MATERIALS AND METHODS:In 289 patients, flexible tantalum stents were implanted in iliac artery stenoses (n - 223) or occlusions (n - 66). Early and late stent failures were evaluated at 1-79 months (mean, 23 months). Four risk factors were evaluated: lesion type (occlusion vs stenosis), lesion location (common vs external iliac artery), lesion length (< 4 vs > 4 cm), and quality of runoff (good vs poor). RESULTS:The frequency of early stent thrombosis was significantly (P < .001) higher in occlusions (15.2%) versus stenoses (2.7%), in external (12.8%) versus common (1.1%) iliac arteries, in long (16.7%) versus short (0.5%) lesions, and in poor (14.0%) versus good (2.1%) runoff. At multivariate analysis, runoff and location were influencing factors. Primary patency rates at 3 and 5 years were 85% and 70%, respectively, for all stents. Three-year patency rates were significantly higher in short (88%) versus long (63%) lesions and in stenoses (92%) versus occlusions (63%). At multivariate analysis, lesion length was the only predictive factor for 3-year stent patency. CONCLUSION:Stent implantation offers valuable long-term treatment for atherosclerotic iliac artery disease. Success can be predicted on the basis of risk factors.
