Key result
Angioplasty-balloon dilatation of normal rabbit iliac arteries increased immediate arteriographic diameter by 32%, but by 28 days diameter returned to normal with intimal thickening.
Why the study?
Does angioplasty-balloon dilation affect arterial wall diameter, histology, response to vasoconstrictors, and passive mechanics in normal rabbit iliac arteries?

Comparison
Angioplasty-balloon dilation of the left iliac… vs Control, right iliac arteries
Design
Preclinical
Follow-up

Suggests intimal proliferation over stiffness as restenosis driver in animals; leaves open human translation.
Does angioplasty-balloon dilation affect arterial wall diameter, histology, response to vasoconstrictors, and passive mechanics in normal rabbit iliac arteries?
Angioplasty-balloon dilation in normal rabbit arteries causes partially reversible changes, suggesting restenosis is likely due to intimal proliferation rather than increased stiffness.
Consigny et al. (1986) studied Normal rabbit iliac artery. Angioplasty-balloon dilatation vs. Control, right iliac arteries was evaluated on Arterial wall diameter, histology, response to vasoconstrictors, and passive mechanics. Angioplasty-balloon dilatation of normal rabbit iliac arteries increased immediate arteriographic diameter by 32%, but by 28 days diameter returned to normal with intimal thickening.
