Summary
Microcatheter embolization is a safe and effective treatment for severe nosebleeds (idiopathic epistaxis). This procedure achieved a high success rate with minimal complications in a retrospective study.
Area of Science:
- Interventional Radiology
- Vascular Surgery
- Otolaryngology
Background:
- Intractable idiopathic epistaxis poses a significant clinical challenge.
- Effective treatment options are crucial for managing severe, persistent nosebleeds.
Purpose of the Study:
- To evaluate the efficacy and safety of microcatheter embolization for treating intractable idiopathic epistaxis.
- To assess technical success, clinical outcomes, and complication rates.
Main Methods:
- Retrospective analysis of 37 patients undergoing microcatheter embolization between 1991-1998.
- Procedures performed using digital subtraction angiography (DSA) under local anesthesia.
- Embolization utilized polyvinyl alcohol (PVA) particles, platinum coils, or a combination.
Main Results:
- Technical success was achieved in all 37 cases (100%).
- A curative outcome was observed in 33 patients (89%) with a mean follow-up of 21 months.
- Mild transient complications occurred in 8% of patients; no severe complications were reported.
Conclusions:
- Microcatheter embolization is a primary, safe, and effective invasive treatment for intractable idiopathic epistaxis.
- The procedure demonstrates sustained efficacy over a significant follow-up period.
