34. Intravascular radiologic interventions II. Interventional radiologic treatment of bleeding, vasoocclusive techniques (embolization, sclerotisation).
- Transcatheter embolization
- Produces emboli which close vessels
- Vessels supplying tumors
- Arteriovenous malformations
- GI tract bleeding
- Aneurysm
- A catheter is lead to the vessel -> particles, glue, etc are ejected -> cause embolization
- Produces emboli which close vessels
- Sclerotisation
- Delivering hypertonic sodium chloride or ethanol by catheter into liver cyst
