Femoral sheath angio
Femoral sheath check angio, 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. SFA: superficial femoral artery (black arrow); Profunda: profunda femoris artery (green arrow). Superficial femoral artery continues into the adductor canal and becomes the popliteal artery behind the knee. Profunda femoris supplies the deep muscles of the thigh. Femoral 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 sheath will be in the external iliac artery. This is retrograde femoral cannulation. Sometimes antegrade puncture and cannulation are resorted to when lower branches of the lower limb arterial system are to be visualized for interventions.
