Femoral arterial sheath check angio is sometimes taken before removing femoral sheath to exclude any extravasation. The contrast is injected through the side arm of the femoral sheath just prior to removal after the interventional procedure. Superficial femoral artery continues into the adductor canal and becomes the popliteal artery behind the knee. Profunda femoris artery supplies the deep muscles of the thigh.

Femoral arterial sheath enters the common femoral artery below the inguinal ligament and above the division into superficial femoral artery and profunda femoris. Tip of the femoral arterial sheath will be in the external iliac artery. This is retrograde femoral cannulation. Proximal end of the femoral arterial sheath has a valve to prevent back bleed once the catheter is removed.

Sometimes antegrade puncture and cannulation are resorted to when lower branches of the lower limb arterial system are to be visualized for interventions. Antegrade puncture is needed during interventions in the femoro-popliteal system. During such procedures subject may be placed in the reverse direction to facilitate movement of the image intensifier system and angiography table.
