Hand Sensibility after Transradial Arterial Access: An Observational Study in Patients with and without Radial Artery Occlusion

Abstract

PURPOSE:

To evaluate hand sensibility after transradial access (TRA) in patients with and without radial artery occlusion (RAO).

MATERIALS AND METHODS:

In this study, 71 patients with and without RAO after TRA for a coronary intervention were studied (79% male, mean age 65 y ± 9). Sensibility testing of both hands was performed with the Semmes-Weinstein monofilaments test. The primary endpoint was abnormal sensibility, defined as diminished sensibility in at least 1 radial nerve–supplied dermatome. The contralateral hand served as control. The influence of TRA, RAO, and clinical characteristics on hand sensibility was evaluated.

RESULTS:

In patients with RAO, more abnormal sensibility was observed on the RAO side compared with the control hand (72% vs 17%, P < .01). In patients without RAO, more abnormal sensibility was observed in the TRA hand compared with the control hand (43% vs 10%, P < .01). When analyzing all hands separately, TRA, RAO, and diabetes were independent predictors for abnormal hand sensibility in a multivariate model (odds ratio 3.8, 95% confidence interval 1.4–9.8, P < .01; odds ratio 3.0, 95% confidence interval 1.1–8.5, P = .03; odds ratio 3.5, 95% confidence interval 1.4–8.6, P < .01).

CONCLUSIONS:

TRA and RAO are associated with diminished hand sensibility.
