Implication

Randomized trial evaluates contributions of geometric remodeling and neointimal growth to restenosis in rabbits, suggesting that geometric remodeling is not the main culprit.

Key Points

This research aims to clarify whether geometric remodeling or neointimal growth is the primary cause of restenosis after balloon angioplasty in rabbits.
Induced focal femoral atherosclerosis via endothelial desiccation injury and a cholesterol diet.
Executed balloon angioplasty with comparisons against controls and treatments with a factor Xa inhibitor antistasin.
Conducted angiography before and after procedures, and analyzed excised arterial segments histomorphometrically.
Postangioplasty, there was an initial increase in luminal diameter followed by significant reduction at 28 days.
Luminal narrowing due to plaque growth was observed, while overall arterial size at restenosis sites remained unchanged in most cases.
In arteries where size changed, the majority showed an increase rather than a decrease.
