Recurrent Epistaxis After Septoplasty: The Judgment Call
A 62-year-old woman on apixaban for atrial fibrillation undergoes septoplasty and inferior turbinate reduction. On postoperative day 7 she returns with recurrent right-sided epistaxis, estimated 400 mL at home, and dizziness on standing. Her blood pressure is 158/92 mmHg, heart rate 104, and hemoglobin has dropped from 13.2 to 10.4 g/dL. Anterior rhinoscopy shows clot along the right septal mucosa but no visible bleeding point; flexible endoscopy shows blood pooling in the right nasopharynx. She is not in respiratory distress. Her INR is not applicable (apixaban), and the last dose was 14 hours ago.
1. What is your stepwise management of this patient, and how do you handle anticoagulation?
Read the worked answer
This is a postoperative posterior or septal bleed with hemodynamic effect (tachycardia, orthostatic dizziness, 2.8 g/dL hemoglobin drop) - treat as significant.
Stepwise:
- Assess and stabilize: IV access, crystalloid, type and screen/crossmatch, monitor. Correct hypotension; control hypertension (target SBP <140) because uncontrolled BP perpetuates bleeding.
- Localize the source: remove clot, perform rigid endoscopy of the nasal cavity and nasopharynx; the pooling in the nasopharynx suggests a posterior source (sphenopalatine artery territory) or a septal branch.
- Control bleeding: attempt endoscopic cautery of a visible vessel; if not visible, anterior/posterior packing or a Foley balloon for posterior epistaxis. Avoid packing that is left too long in an anticoagulated patient without reassessment.
- Anticoagulation: do not simply stop apixaban indefinitely. With active significant bleeding, hold the next dose, achieve local control, and restart as soon as hemostasis is secure in consultation with cardiology, because stroke risk from AF is real. Reversal agents (andexanet alfa or PCC) are reserved for life-threatening bleeding.
- Escalate to endoscopic sphenopalatine artery ligation or interventional radiology embolization if packing fails or bleeding recurs.
- Transfuse if hemodynamically unstable or hemoglobin continues to fall.
2. Two days later she rebleeds despite packing. What is the definitive management, and what anatomic landmark guides you?
Read the worked answer
Definitive management is endoscopic sphenopalatine artery (SPA) ligation (or embolization if surgery is not feasible).
Key points:
- The SPA exits the sphenopalatine foramen at the posterior lateral nasal wall, posterior to the middle turbinate and inferior to the sphenoid ostium; the foramen is found by removing the posterior fontanelle of the middle meatus and identifying the crista ethmoidalis.
- Bilateral or posterior bleeding may require bilateral ligation; the SPA is the dominant supply to the posterior nasal cavity.
- Embolization is an alternative when endoscopy fails or the patient is a poor surgical candidate, but carries risks of stroke and blindness via anastomoses.
- After control, restart anticoagulation with cardiology input, treat hypertension, and counsel on avoiding NSAIDs and nose blowing.
- Document that the patient was on apixaban and that reversal was considered but not required.
