Effect of the Transradial Approach on Wrist Function in Diagnostic Cerebral Angiography

<b>Background</b>: With increasing demand for ambulatory catheter angiography, interest in the transradial approach for diagnostic cerebral procedures has grown markedly. This study aimed to evaluate the effect of the transradial approach for catheter-based diagnostic cerebral procedures on wrist function. <b>Methods</b>: Wrist function was quantified by the Patient-Rated Wrist Evaluation (PRWE) questionnaire. The PRWE score ranged from 0 to 100, with 0 indicating no functional impairment. Association analyses with demographic and clinical parameters were performed using univariate logistic regression models. <b>Results</b>: A total of 88 patients underwent ambulatory diagnostic cerebral angiography during the 15-month observation period; of these, 40 (45%) participated in a telephone interview. Overall, 47.5% (<i>n</i> = 19) of patients reported no wrist impairment (PRWE = 0) after the transradial approach. The remaining 52.5% (<i>n</i>= 21) showed a mean PRWE score of 21.3 ± 22.5 (standard deviation), with a median value of 11.0 and a range from 1.0 to 87.0. Interestingly, univariate logistic regression models revealed a trend towards association between the dichotomized PRWE score and body mass index (<i>p</i> = 0.051). No associations were found with age, sex, prior neurosurgical status, total procedure duration, dose area product, fluoroscopy time, or dominant hand (<i>p</i> > 0.05). <b>Conclusions</b>: Following transradial cerebral catheter angiography, 52.5% of patients reported some degree of wrist impairment at follow-up; whether this represents procedure-related deterioration cannot be determined without baseline values.
