Epistaxis01:30

Epistaxis

220
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...

Summary
This summary is machine-generated.

This study introduces a "distributed map" for precise diagnosis and treatment of intractable epistaxis (nosebleeds). Bipolar radiofrequency ablation under nasal endoscopy effectively stops bleeding without packing, offering a recommended precise approach.

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Interventional Procedures

Background:

  • Intractable epistaxis presents a significant clinical challenge.
  • Accurate localization of bleeding sites is crucial for effective treatment.
  • Current treatment modalities may lack precision in identifying specific bleeding vessels.

Purpose of the Study:

  • To develop and present a novel
  • distributed map
  • for visualizing concealed bleeding regions and offending vessels in intractable epistaxis.
  • To recommend a precise diagnostic and therapeutic strategy for refractory epistaxis based on this map.

Main Methods:

  • Integration of extensive big data from Chinese research.
  • Application of clinical expertise to refine understanding of epistaxis.
  • Development of a concise
  • distributed map
  • illustrating bleeding anatomy.
  • Utilization of nasal endoscopy with bipolar radiofrequency ablation for hemostasis.

Main Results:

  • The
  • distributed map
  • clearly identifies concealed bleeding regions and offending vessels.
  • Accurate bleeding site localization was achieved using the map.
  • Successful hemostasis was achieved via bipolar radiofrequency ablation without nasal packing.
  • Five classic cases demonstrating the efficacy of the proposed method were presented.

Conclusions:

  • The developed
  • distributed map
  • provides a precise tool for diagnosing intractable epistaxis.
  • Nasal endoscopic bipolar radiofrequency ablation is an effective treatment modality for refractory epistaxis.
  • This precise mode of diagnosis and treatment is recommended for clinical practice.
