A Comparative Study between the Routine Using of Ultrasound Guidance versus Anatomical Guidance in Femoral Artery Access for Endovascular Treatment of Chronic Lower Limb Ischemia

The goal of this study is comparison between the using of ultrasound guidance versus anatomical guidance in femoral artery access for endovascular treatment of chronic lower limb ischemia, by assessment of first pass success rate, total number of attempts required for access, rate of accidental venipunctures, rate of PFA puncture and time to sheath insertion, and assessment of post procedural puncture site complications defined as bruises or hematoma formation. The study found that US guidance is superior to anatomical guidance in femoral artery access in endovascular treatment of chronic lower limb ischemia in reducing access time, total number of punctures, and number of incidental venipuncture, the incidence of PFA access and incidence of local bruises.
