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
