| Abstract | The transradial approach has been used for coronary procedures, but this procedure carries a risk of injury to the endothelium of the radial artery. In this study, the vascular dysfunction caused by transradial catheterization was examined using reactive hyperemia peripheral arterial tonometry (RH-PAT), a recently developed technique for assessing endothelial function in digits, and the differences in injuries were compared according to the size of sheath.Forty-three patients undergoing transradial catheterization with 6-Fr sheaths (n = 17) or 4-Fr/5-Fr (non-6-Fr; n = 26) sheaths underwent RH-PAT using an Endo-PAT2000 before, the day after, and 6 months after catheterization. RH-PAT was assessed in the arm of sheath placement and in the other arm as a control.RH-PAT values decreased from 2.42 ± 0.67 before catheterization to 2.08 ± 0.41 the day after catheterization in the 6-Fr group (P = 0.031); this was more evident in patients with a longer procedure time (> 91 minutes). In contrast, the change in the non-6-Fr group was not significant. RH-PAT of the non-catheterized arm was unchanged in both groups. At 6 months after catheterization, RH-PAT values in the 6-Fr group had not completely returned to baseline.In conclusion, the insertion of a 6-Fr catheter sheath into the radial artery, especially with a longer procedure time, impaired vascular endothelial function assessed by RH-PAT the day after the procedure and was sustained for 6 months. Thus, the use of smaller size sheaths (< 6-Fr) with a shorter procedure should be considered when performing transradial catheterization. |
