title: Results of iliac artery stent placement in patients younger than 50 years of age.
abstract: OBJECTIVE
  To determine long-term outcome in patients 50 years of age or younger treated with iliac artery stent placement.
  
  
  METHODS
  The records of 412 patients who underwent iliac artery stent placement during a 62-month study period were reviewed retrospectively. Forty-two patients younger than age 50 (mean age = 45 y) at the time of stent placement were included in the study population. Presenting symptoms included claudication (47%), rest pain (17%), ulceration/tissue loss (31%), and blue toe syndrome (5%). Anatomic, hemodynamic, and clinical success rates of the stent placement procedure were assessed. Stent patency rates were calculated by life-table methods.
  
  
  RESULTS
  Fifty-nine iliac lesions were treated with stents; 62% of patients underwent treatment of a single lesion whereas 38% had multiple lesions treated. Thirty-one percent were treated after a failed angioplasty procedure and 69% were treated with stent placement primarily. After stent placement, 34 patients (82%) experienced symptomatic relief, although eight of these patients (19%) underwent a planned ipsilateral infrainguinal bypass procedure during the same hospitalization. During follow-up, five patients (12%) required a bypass procedure as a result of stent failure and two patients (5%) required below-knee amputation. Seven patients (17%) required endovascular stent revision, with none requiring additional surgery. At 1, 2, and 3 years, the primary patency rates were 86%, 72%, and 65%, and the secondary patency rates were 90%, 88%, and 88%, respectively.
  
  
  CONCLUSIONS
  Iliac stent placement successfully addresses the presenting symptoms of young patients with peripheral vascular disease and results in patency rates that are similar to those reported in a more general population. With appropriate postprocedural surveillance, restenosis can be addressed in many patients with use of endovascular techniques, limiting the need for surgical revision.
