Abstract
Background
Transradial approach (TRA) has been increasingly utilized in various neuroendovascular interventions as a safe alternative to the transfemoral approach (TFA). As middle meningeal artery (MMA) embolization emerges as an effective therapy for treating chronic subdural hematomas (cSDH), some studies have explored using TRA. In this study, we compared procedural times and post-operative outcomes between those with TRA and TFA.
Methods
This is a single-institution retrospective study of patients undergoing MMA embolization for cSDH. The cohort was divided into the TRA and TFA subgroups. Baseline characteristics, procedural times, and immediate outcomes were compared. Univariate analysis was performed.
Results
We performed 62 MMA embolizations for treatment of cSDH, of which 37 (59.7 %) were performed transradial and 25 (40.3 %) were performed transfemoral. Those who underwent TRA were significantly younger than those who had TFA (p = 0.02). For patients who underwent unilateral MMA embolization, those with TRA had significantly shorter duration of procedure compared to the TRF group (p = 0.01). This difference was not observed in the bilateral MMA embolization subgroup. Only three patients had access site complications, and all were in the TFA group. There was no significant difference in length of hospital stay.
Conclusion
As MMA embolization for cSDH becomes more prevalent, efforts to optimize the safety and efficacy of the technical aspects become critical. In this study we demonstrate that TRA is a safe and efficient alternative to traditional TFA in those undergoing unilateral MMA embolization.
