NCT00126204

Brief Summary

The durability of endovascular aneurysm repair (EVAR) has been limited by development of endoleaks which may be secondary to progressive aortic degeneration by matrix metalloproteases (MMP). Doxycycline is a known inhibitor of the MMP family of enzymes in aneurysms. The investigators propose a randomized, controlled trial of adjuvant doxycycline therapy with EVAR to determine its effects on re-intervention, aneurysm shrinkage and serum markers of aneurysmal degeneration.
