The constrictive response of arterial segments following intraluminal balloon angioplasty was studied angiographically in dogs and rabbits. Following intravenous administration of vasopressin, the dilated segment showed no change in caliber, whereas the normal arterial wall contracted. This suggests that one effect of angioplasty is immediate and permanent damage to the muscular component of the media.
