Diagnosis: Posterior Epistaxis Due to Hypertension
The most likely diagnosis is posterior epistaxis due to hypertension (Option A), given the patient's hypertensive history, prolonged 30-minute bleeding episode, pallor suggesting significant blood loss, and recurrent symptoms—all classic features of posterior epistaxis in hypertensive patients. 1
Clinical Reasoning
Why Posterior Epistaxis Due to Hypertension is Most Likely
Hypertension is strongly associated with posterior epistaxis, with 48% of posterior epistaxis patients having a history of hypertension, and this patient population experiences more severe, difficult-to-control bleeding. 1, 2
The 30-minute bleeding duration indicates severe epistaxis, as posterior epistaxis accounts for 5-10% of all nosebleeds but presents with more difficult-to-control bleeding requiring hospitalization. 1
Pallor suggests significant blood loss, which is characteristic of posterior epistaxis where 12.3% of patients require blood transfusions due to severity. 2
Recurrent nasal congestion and obstruction are consistent with posterior bleeding that is not visible on anterior examination and requires nasal endoscopy for definitive diagnosis. 1
The age and hypertension combination dramatically increases epistaxis severity and complications, with elderly hypertensive patients at high risk for posterior sources. 3
Why NOT Hereditary Hemorrhagic Telangiectasia (Option C)
HHT requires visible telangiectasias on nasal or oral mucosa, which are not mentioned in this presentation. 1
HHT typically presents with recurrent bilateral nosebleeds starting in childhood or adolescence, not as a new presentation in a hypertensive adult. 1
The unilateral presentation with nasal obstruction does not fit the classic bilateral pattern of HHT. 3
Why NOT Nasal Hemangioma (Option B)
Nasal hemangiomas present with a visible mass lesion on examination, typically causing unilateral obstruction with associated symptoms like facial pain. 1
Hemangiomas are uncommon causes of epistaxis and would be identified during anterior rhinoscopy or endoscopy. 1
The recurrent nature without mention of a mass makes this diagnosis unlikely. 3
Critical Management Considerations
Blood Pressure Management Pitfall
Do NOT aggressively lower blood pressure acutely during active epistaxis, as excessive reduction can cause or worsen renal, cerebral, or coronary ischemia in patients with chronic hypertension. 1, 3
Blood pressure should be monitored but decisions about control must be based on bleeding severity and individual comorbidities. 1
Immediate Next Steps
This patient requires emergency department evaluation given the bleeding duration >30 minutes, signs of hemodynamic instability (pallor), and potential need for posterior packing or endoscopy. 3
Check anticoagulation status, as 15% of epistaxis patients are on long-term anticoagulation, which significantly impacts management. 1
Assess for hemodynamic compromise including tachycardia, hypotension, or orthostatic changes, as these indicate significant blood loss requiring hospital-level care. 3
