ANSWER AND REASONINGB. Treat this as a sentinel bleed and arrange urgent specialist carotid-blowout assessment
A warning bleed in an irradiated recurrent neck can precede catastrophic haemorrhage. The pathway requires immediate escalation, airway planning and endovascular/vascular expertise.
Why every option is right or wrong
A. Schedule routine outpatient biopsy: Delay and instrumentation may be dangerous.
B. Treat this as a sentinel bleed and arrange urgent specialist carotid-blowout assessment: A warning bleed in an irradiated recurrent neck can precede catastrophic haemorrhage. The pathway requires immediate escalation, airway planning and endovascular/vascular expertise.
C. Reassure because the bleeding stopped: Temporary cessation does not remove major vascular risk.
D. Start anticoagulation for presumed thrombosis: This may worsen haemorrhage.
E. Proceed with blind neck exploration: Unplanned exploration risks exsanguination or stroke.
What if the scenario changed?
If bleeding were from a clearly visualised minor mucosal source without recurrent irradiated disease, the risk assessment would be different.
