Abstract
Background
There has been debate in the literature regarding the adoption of a “radial-first” approach for mechanical thrombectomy (MT) in acute ischemic stroke (AIS). Conflicting reports suggest that transradial access (TRA) may allow for shorter times to reperfusion while others conclude that long-term functional outcomes may favor transfemoral access (TFA). Here, we report a single-institution experience with the adoption of TRA as the primary route for acute stroke intervention.
Methods
We retrospectively reviewed a single-institution database of patients undergoing MT for AIS from March 2020 to April 2023. This time period was selected to capture the change in clinical practice at our institution from TFA to TRA. Primary and secondary outcomes included technical success, procedural complications, and long-term functional outcomes. Patients were stratified into two cohorts from initial access. Cohorts were compared utilizing inferential statistics.
Results
A total of 192 consecutive cases were identified, with 80 in the TFA cohort and 112 in the TRA cohort. There was no difference in outcomes with respect to time from puncture to recanalization, rates of successful recanalization (TICI ≥ 2b), number of passes, rates of symptomatic intracranial hemorrhage (sICH), modified Rankin scale (mRS) at discharge and 90 days, and 90-day mortality (p ≥ 0.05, all). The TRA had a higher rate of access conversion (p < 0.001), while the TFA cohort had a higher rate of access site complications (p < 0.05).
