Abstract

Purpose:

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.

Conclusion:

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.
