Summary
Refractory carotid-cavernous fistula (CCF) causes include anatomical issues and prior treatments. Effective management of complex CCF requires skilled embolization and tailored approaches.
Area of Science:
- Vascular Surgery
- Interventional Neuroradiology
Context:
- Carotid-cavernous fistula (CCF) is an abnormal connection between the carotid artery and the cavernous sinus.
- Refractory CCF presents significant management challenges, often stemming from complex anatomy or prior inadequate treatments.
Purpose:
- To investigate the underlying causes of refractory carotid-cavernous fistula (CCF).
- To identify effective countermeasures and treatment strategies for complex CCF cases.
Summary:
- This study reviewed 12 refractory CCF cases from 123 traumatic CCF patients over 12 years.
- Identified causes include fistula opening size, parent artery constriction, and suboptimal prior interventions (e.g., carotid ligation, coil packing, balloon issues).
- Successful anatomical cure was achieved in 11 cases and clinical cure in one using various embolization techniques (balloon, coils, NBCA) via arterial, venous, or surgical routes.
Impact:
- Highlights the importance of precise catheterization and embolization techniques for refractory CCF.
- Emphasizes tailoring treatment approaches and embolic materials to specific fistula characteristics for improved outcomes.
