OBJECTIVES: To compare incidence of forearm radial artery occlusion (RAO) and hemostasis characteristics between distal and conventional transradial approach (DRA and TRA, respectively).
BACKGROUND: DRA has the potential advantage of reducing RAO. DRA effectively reduces time-to-hemostasis, however its role on preserving flow in the radial artery (PF) during hemostasis and consequent impact on RAO remains speculative.
METHODS: Eight hundred thirty-seven patients with TRA were previously enrolled in a prospective registry investigating the relationship of residual anticoagulation and RAO. Three hundred twenty-six additional patients with DRA were added to the cohort and matched to the original cohort by propensity score. The composite end-point of RAO at forearm and distal site of puncture (dRAO) was evaluated as secondary end-point.
RESULTS: RAO occurred in 4.8% (41 of 837) of patients undergoing TRA and in 0% (0 of 326) of those undergoing DRA (p < 0.0001). DRA was associated with higher percentage of PF (97.2% vs. 78.5% in TRA group, p < 0.0001) and reduced time-to-hemostasis (147 ± 99 min vs. 285 ± 138 min, p < 0.0001). After matching, hemostasis characteristics were still significant different (PF 95.7% vs. 90.1%, p = 0.023, and 190 ± 92 vs. 323 ± 162 min, p < 0.0001) with reduction in the incidence of RAO (0 of 213, 0% vs. 7 of 213, 3.3%, p = 0.0015). dRAO occurred in one case (0.3% and 0.5% after matching, p < 0.0001 and p = 0.032 compared to TRA).
CONCLUSIONS: DRA was associated with lower rates of RAO compared to TRA. This effect is potentially explained by reduced time-to-hemostasis and maintained flow at the wrist during hemostasis.
