title: Stent placement for treatment of mesenteric artery stenoses or occlusions.
abstract: OBJECTIVE
  To evaluate stent placement in the treatment of mesenteric ischemia.
  
  
  METHODS
  Twelve patients (eight women, four men; mean age, 63 years) with chronic mesenteric ischemia underwent stent placement for stenoses or occlusions during a 5.5-year period. Nine patients with 10 stenoses (three celiac arteries, seven superior mesenteric arteries) and three patients with three chronic occlusions (two superior mesenteric arteries, one aortosuperior mesenteric artery bypass graft) were treated.
  
  
  RESULTS
  Initial technical success was achieved in 11 of the 12 patients (92%), including all three patients with chronic occlusions. There were no technical complications. There was one postprocedural death (<30 days) due to bowel ischemia and infarction, despite a technically successful procedure. Clinical follow-up was available in all 12 patients, with a mean follow-up of 15.7 months (range, 0-38.5 months). Primary and primary-assisted patency up to 18 months was 74% (standard error [SE], 13%) and 83% (SE, 11%), respectively. Secondary patency was 83% (SE, 11%) at 3 years. All three patients (100%) with chronic occlusions had relief of clinical signs and symptoms at a mean follow-up of 22 months (range, 13-38.5 months).
  
  
  CONCLUSIONS
  Stent placement is safe and clinically effective as an adjunctive therapy to angioplasty or as a primary method of treatment for chronic mesenteric ischemia in patients with focal visceral artery stenoses or occlusions.
