ABSTRACT
The vasomotor response was used to assess the degree of radial artery injury after transradial catheterization. Vasoreactivity was studied by ultrasound before catheterization, 24 hours after, at 1 week and at 1 month in 18 patients. Mean radial artery diameter increased from 2.56+/-0.45 mm before catheterization to 2.86+/-0.48 mm at 24 hours (p=0.001) and returned to baseline values at 1-month (2.60+/-0.27 mm; p=0.95). Hyperemia-induced vasodilation did not change significantly (2.7+/-4.7% at baseline; 3.4+/-3.7% at 24 hours, 3.5+/-3.9% at 1 week and 4.8+/-4.7% at 1 month; p=0.59). Nitroglycerin-induced vasodilation was significantly attenuated at 24 hours (from 14.1+/-7.9% at baseline to 6.5+/-8.4% at 24 hours; p=0.01), but improved after 1 week (9.8+/-8.5%; p=0.1, compared to baseline) and after 1 month (13.0+/-8.9%; p=0.51, compared to baseline). Thus, soon after transradial catheterization vasoreactivity is impaired, but generally recovers as early as 1 month after the procedure.
