We assessed long\u2010term patency after percutaneous revascularization of long femoral artery lesions for claudication with intensive out\u2010patient surveillance. <jats:styled-content>Methods<\/jats:styled-content>: We followed a cohort of 111 consecutive patients receiving angioplasty or stenting in 142 limbs in two institutions. Patients were followed for 2.5 years, and event curves and multivariable survival analysis used to compare outcomes in three groups according to lesion length (&lt; 100 mm, 100\u2013200 mm, and greater than 200 mm). Failed patency was defined as recurrence of symptoms with a decline in ankle brachial index, or stenosis identified by duplex ultrasound, or reintervention. <jats:styled-content>Results<\/jats:styled-content>: Compared to lesions less than 100 mm, longer lesions had higher failed primary patency (100\u2013200 mm: HR = 2.0, <jats:italic>P<\/jats:italic> = 0.16, &gt;200 mm: HR = 2.6, <jats:italic>P<\/jats:italic> = 0.03). Failed secondary patency was similar for short and intermediate lesions (&lt; 5% incidence), but trended higher for lesions &gt;200 mm (HR = 4.2, <jats:italic>P<\/jats:italic> = 0.06). An initial procedure residual stenosis greater than 20% was the only significant multivariable factor related to poorer long\u2010term patency (HR = 15.8, <jats:italic>P<\/jats:italic> = 0.003). Compared to short lesions, the gain in long\u2010term patency with out\u2010patient surveillance and reintervention was higher for longer lesions and significantly so for intermediate lesions (100\u2013200 mm = 23% versus &lt;100 mm = 8%, <jats:italic>P<\/jats:italic> = 0.041). <jats:styled-content>Conclusion<\/jats:styled-content>: Percutaneous treatment of long femoral artery lesions can provide acceptable long\u2010term patency for patients with claudication when out\u2010patient surveillance is used to identify patients who require repeat interventions. Future long\u2010term studies should consider overall patency encompassing more than one percutaneous reintervention. \u00a9 2011 Wiley\u2010Liss,
