Does ultrasound guidance decrease femoral access site complications in neurointerventional procedures? A retrospective cohort study.

Background: Ultrasound has been increasingly used to guide femoral arterial access for neuroendovascular procedures. Its effect on the safety outcomes has yet to be established.

Purpose: The purpose is to determine the effect of ultrasound-guided punctures on femoral access site complications (ASC), and to identify other potential predictors of ASC.
