Trans-radial vs. trans-femoral approaches in diagnostic cerebral angiography: A comprehensive systematic review and meta-analysis of practicality and cost-effectiveness.

Background: Selecting most appropriate approach between the transfemoral access (TFA) and transradial access (TRA) for diagnostic cerebral angiography is a subject of debate.

Objective: To compare the safety and efficacy of TFA and TRA for diagnostic cerebral angiography.

Methods: We performed a systematic search through four databases to find relevant clinical studies.
