TIPS

  • Use Color Doppler to facilitate identification of the popliteal vessels
  • When performing a medial to lateral approach, needle insertion in a steep angle is required to stay close to the femoral shaft and avoid puncture of the nerves and vessels
  • With the medial-lateral needle insertion technique, routine ultrasonographic identification of the saphenous nerve is recommended to determine the safe needle insertion site and pathway.
