title: Angioplasty/stenting of the superior mesenteric artery and celiac trunk: early and late outcomes.
abstract: OBJECTIVE
  To analyze the early results and durability of angioplasty/stenting of the superior mesenteric artery (SMA) and celiac trunk (CT).
  
  
  METHODS
  Twenty-two patients (19 women; mean age 69.2 years, range 52-88) with 24 symptomatic SMA or CT stenotic lesions were treated with dilation/stenting over a recent 4.5-year period. Two patients had lesions in both the SMA and CT treated. Clinical follow-up and duplex exams were done to evaluate long-term patency. Kaplan-Meier life-table analyses estimated the freedom from recurrent stenosis and recurrent symptoms, as well as survival rates.
  
  
  RESULTS
  The initial technical and clinical success rates were 96% (23/24) and 95% (21/22), respectively, with no perioperative mortality or major morbidity. During a mean follow-up of 26 months (range 1-54), the primary late clinical success rate was 61% (11/18; 4 lost to follow-up), and freedom from recurrent stenosis (> or =70%) was 30% (6/20). The freedom from recurrent stenosis at 1, 2, 3, and 4 years were 65%, 47%, 39%, and 13%; freedom from recurrent symptoms was 67% at all 4 intervals. The survival rates were 93%, 93%, 80%, and 53% at 1 to 4 years, respectively.
  
  
  CONCLUSIONS
  Angioplasty/stenting of SMA and CT stenoses has a high initial technical success rate and acceptable early and late clinical outcomes; however, it is associated with a high incidence of late restenosis based on strict Doppler criteria.
