title: Endovascular reconstruction of the occluded aortoiliac segment using "double-barrel" self-expanding stents and selective use of the Outback LTD catheter.
abstract: OBJECTIVE
  To present the early and midterm results of endovascular stent reconstruction of the occluded aortoiliac segment with selective use of the Outback LTD re-entry catheter.
  
  
  METHODS
  Between April 2004 and February 2010, 8 patients (5 women; mean age 58.4 years, range 47-68) with occlusion of the infrarenal aorta extending to the common or external iliac arteries underwent endovascular reconstruction with double-barrel self-expanding stents. Indications for treatment were severe claudication in 6 and ulceration in 2 patients.
  
  
  RESULTS
  The technical success rate was 100%, facilitated by the use of the Outback LTD catheter for accurate wire re-entry in 3 cases. There was no in-hospital mortality. One patient had a major complication (femoral artery dissection, brachial artery thrombosis, and retroperitoneal hematoma) unrelated to the re-entry device. Mean operating time was 137 minutes (range 70-253) and length of stay was 1.5 days (range 1-2). During a mean follow-up of 12.5 months (range 6-29), primary patency was 100% with no secondary interventions.
  
  
  CONCLUSIONS
  Total endovascular reconstruction of the occluded infrarenal aorta that extends into the iliac arteries is durable at midterm follow-up. Adjunctive use of the Outback LTD re-entry catheter can facilitate technical success.
