Epistaxis01:30

Epistaxis

653
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

1.8K
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Summary
This summary is machine-generated.

A rare case of severe nosebleeds (epistaxis) was treated in a 74-year-old male. Doctors identified and successfully embolized a pseudoaneurysm of the descending palatine artery, a potentially life-threatening condition.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Otolaryngology

Background:

  • Recurrent epistaxis can indicate serious underlying vascular pathology.
  • Maxillofacial trauma and surgery are known risk factors for vascular complications.

Observation:

  • A 74-year-old male presented with recurrent epistaxis following Le Fort 1 osteosynthesis.
  • Computed Tomography (CT) revealed a pseudoaneurysm of the left descending palatine artery within the maxillary sinus.

Findings:

  • The descending palatine artery pseudoaneurysm was successfully treated with embolization.
  • Pseudoaneurysms of the internal maxillary artery branches are rare but critical diagnoses.

Implications:

  • Consider pseudoaneurysms in patients with recurrent head and neck bleeding, particularly post-trauma or surgery.
  • Prompt diagnosis and endovascular embolization are crucial for managing this life-threatening condition.
