title: Drug-eluting stent for recurrent mesenteric artery in-stent restenosis.
abstract: OBJECTIVE
  To report the use of a drug-eluting stent (DES) for treatment of symptomatic in-stent restenosis (ISR) in the superior mesenteric artery (SMA).
  
  
  METHODS
  A 79-year-old woman suffering from chronic renal failure and needing dialysis was admitted for vomiting, postprandial abdominal pain, and weight loss for 3 months. Computed tomographic angiography (CTA) documented massive calcification of the vascular bed, mainly in the aorta, and a very tight ostial stenosis of the SMA. A 4.5-x20-mm Genesis stent was deployed at the ostium, with good angiographic result and immediate symptomatic benefit. After 3 months, symptoms recurred; angiography demonstrated ISR. Percutaneous angioplasty with a 4-x15-mm cutting balloon was performed. The patient remained asymptomatic for only 2 months; recurrent ISR at this time was treated with a 3.5-x24-mm coronary TAXUS Express paclitaxel-eluting coronary stent deployed inside the previously implanted stent. Under prolonged double antiplatelet regimen, the patient was asymptomatic at the 8-month follow-up; CTA demonstrated patency of the SMA.
  
  
  CONCLUSIONS
  Considering the high rate of restenosis and the periprocedural complications described with endovascular treatment of SMA stenosis, a drug-eluting stent may be a good option not only for the treatment of restenosis but also in de novo lesions, at least when the vessel diameter is <4.5 mm.
