RESUMO
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.
