Transradial access for renal artery intervention is feasible and safe

Background: Transradial access for coronary intervention is associated with reduced access complications compared with transfemoral. Transradial access for renal artery intervention has been less well studied. Safety compared with transfemoral access is undetermined. Methods and Results: We evaluated the feasibility of transradial renal intervention (n = 11 patients) and compared safety parameters with a matched group of transfemoral controls (n = 44). All transradial interventions were successful with no complications. Femoral crossover was required in one due to insufficient guide length. Compared with transfemoral, there were fewer access complications in the transradial group (0 of 11 vs 3 of 44, P =.06) but no differences in fluoroscopy time or contrast volumes (25.3 ± 14.4 vs 29.0 ± 25.1 minutes, P =.47; 83.0 ± 43.7 vs 82.6 ± 35.2 cc, P =.97). At follow-up (median 6 months), radial patency was 100%. Creatinine and systolic blood pressure had decreased (mean 1.4 ± 0.5 to 1.2 ± 0.5, P =.06; 160 ± 25 to 135 ± 17, P =.009). Conclusions: Elective transradial renal intervention is feasible and safe. Radial-renal distance is a limitation with available guides.
