Percutaneous revascularization of long femoral artery lesions for claudication: patency over 2.5 years and impact of systematic surveillance.

摘要: Background: Angioplasty and stenting are preferred treatments for revascularizing femoral artery lesions up to 100 mm, but surgical bypass is recommended longer lesions. We assessed long-term patency after percutaneous revascularization of long claudication with intensive out-patient surveillance. Methods: followed a cohort 111 consecutive patients receiving angioplasty or in 142 limbs two institutions. Patients were 2.5 years, event curves multivariable survival analysis used compare outcomes three groups according lesion length ( 200 mm: HR = 2.6, P 0.03). Failed secondary was similar short intermediate mm (HR 4.2, 0.06). An initial procedure residual stenosis greater than 20% the only significant factor related poorer 15.8, 0.003). Compared lesions, gain surveillance reintervention higher significantly so (100–200 23% versus <100 8%, 0.041). Conclusion: Percutaneous treatment can provide acceptable when identify who require repeat interventions. Future studies should consider overall encompassing more one reintervention. © 2011 Wiley-Liss, Inc.
