Cryoplasty versus angioplasty in the treatment of arterial restenosis in an experimental model of atherosclerosis in rabbits

Intravascular cryotherapy induces complicated lesions in arterial walls 30 days after treatment in a hypercholesterolemic rabbit model based on diet plus vessel injury. Cryoplasty leads to the production of severe fibrosis and mineralisation and stenosis compared to a conventional angioplasty.
