Table 2 Comparison of transradial and transfemoral arterial access

From: Intraoperative transradial angiography augments safe hysterectomy for uterine fibroids in the setting of ambiguous arterial anatomy: a case report

  Transradial access (TRA) Transfemoral access (TFA)
Entry point Radial artery Femoral artery
Founded 1989 ~1960s
Advantages • Superficial artery for easier visualization
• Readily compressible
• Less susceptible to effects of thrombosis due to dual blood supply of the hand
• Hemostasis achieved without the introduction of a vascular closure device (transradial band used instead)
• Shorter procedural time
• Faster recovery time with immediate ambulation
• Lower procedural cost
• Studies indicate 100% technical success rate at 1-month follow-up
• Fewer bleeding complications
• Lower rates of morbidity and mortality
• Many trained physicians comfortable with this approach
• Large arterial diameter
• Long history of success
Disadvantages • Learning curve that can lead to vascular complications
• Small radial artery diameter
• Radial artery spasm, radial artery occlusion, and/or forearm hematoma
• Higher risk of hemorrhage
• Longer time necessary until discharge
• Greater procedural cost
• Femoral artery provides the only blood supply to the leg; occlusion can have severe consequences
