Purpose: To evaluate the efficacy, safety, and feasibility of transradial approach (TRA) for endovascular management of traumatic bleeding.
Materials and methods: A retrospective review was performed at a single level 1 trauma institution from August 2018 to July 2019. Patients presented to the interventional radiology department who were intended to be treating using TRA for the management of trauma-induced bleeding were selected. Demographics, indication for embolization, embolization site, preprocedural labs, hemodynamic stability, technical success, and complications were recorded.
Results: Transradial approach was attempted in 29 (74.4%) of the 39 patients identified by operators who prefer TRA. Four patients received treatment using TRA on 2 separate occasions, for a total of 33 procedures completed with a technical success of 97% (32/33). Transradial approach was safely completed in 9 patients (27.3%) with preprocedural hemodynamically unstable status. For the 10 patients who received treatment via a transfemoral approach (TFA), traumatic disfiguration of the left upper extremity, preexisting arterial lines placed by the trauma team, and external iliac artery injuries requiring covered stent placement were the most common indications for TFA over TRA. There were no procedural or access site-related complications.
Conclusion: Transradial approach for the endovascular management of bleeding in a trauma setting is safe and effective with a high technical success rate and no complications.
