Educational content only — not medical advice.
Anatomy
Ascends in the carotid sheath with the jugular vein and vagus nerve, bifurcating at C4 into internal and external branches; its mid-neck course is the emergency compression point for haemorrhage control.
Clinical notes
Atheromatous stenosis at the bifurcation causes recurrent TIAs and amaurosis fugax; penetrating injury bleeds fatally without immediate direct pressure.
