During femoral artery catheterisation, the catheter tip is tracked into the adductor canal. Which two structures accompany the femoral artery within this canal?

• A Medial femoral circumflex artery and femoral branch of genitofemoral nerve
• B Femoral vein and obturator nerve
• C Saphenous nerve and nerve to vastus medialis ✓
• D Great saphenous vein and ilioinguinal nerve

Explanation

The adductor (subsartorial, Hunter's) canal runs from the apex of the femoral triangle to the adductor hiatus and contains the femoral artery, the femoral vein, the saphenous nerve, and the nerve to vastus medialis. The saphenous nerve crosses anterior to the artery from lateral to medial side. The obturator nerve enters the thigh separately through the obturator foramen and never enters the canal.
