Excluding 21 (7%) surgical cases, the remaining 274 patients were treated either conservatively (n = 165) or with PTA (n = 109). Medical history, physical findings, and sonographic and angiographic data were recorded from the medical records of the 223 (81%) patients who were followed until the year 2000; 166 patients were then reinvestigated with oscillography, Doppler measurements, and duplex sonography. Outcomes of conservative versus interventional therapy were analyzed based on the intention to treat principle.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>After a median 42-month follow-up (interquartile range 18\u201385), patients treated with PTA had a 60% risk reduction for hemodynamic subclavian stenosis compared to conservative treatment (adjusted hazard ratio 0.4, 95% confidence interval 0.2\u20130.6, p&lt;0.0001). However, the risk of having a symptomatic stenosis at the time of follow-up did not differ between the treatment groups (p=0.3).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Endovascular revascularization improves the long-term hemodynamic outcome in patients with subclavian stenosis, but many conservatively treated patients become asymptomatic during follow-up.
