Morphological and histologic study after atherectomy in normal and atherosclerotic rabbit iliac arteries

Percutaneous transluminal atherectomy has been developed for treatment of peripheral artery stenosis 2,5,13. Although Directional Atherectomy (DA) reduces the plaque burden, successful revascularization is not associated with a reduced restenosis rate when compared with others methods of revascularization 4,7,21.

The atherectomy devices perform a cleaning on  the inside of the vessel wall, cutting the occlusive material,  achieving its repermeabilization while achieving a more or less  regular vascular light, maintaining the vascular structure with  only part of the parietal structure of the glass. Afterwards, bio-  logical healing processes are produced, although it seems that intimal hyperplasia can occur that re-light the repermeabilized lumen

The purpose of this study was to evaluate the his- tologic and morphologic effects of a new high speed rotary atherectomy device (HawkOne) on rabbit iliac arteries.
