Intervential Radiology Flashcards
Image-guided interventions:
- Drainage
- Biopsy
- Enteral Access
- Vascular Access
- Vascular Interventions
When is drainage used? What is commonly used with drainage?
- Fluid
- Abscess
- - Abx are adjunctive
When do you want to drain pleural fluid?
- Loculated Empyema
- Simple Effusion
** Drainage may provide relief of symptoms but does not necessarily treat the underlying cause
Methods of Drainage:
- Blind Percutaneous (Auscultate and know your anatomy)
- Image-based (CT or US)
***Situation can dictate which one is used
Pros and Cons of image guided drainage?
Pros: More precision for loculated fluid collection
Cons: Perforation/Anatomy
What type of abscesses would potentially need image guided drainage?
Deep Tissue Abscess
Why do we use biopsies?
- Less morbidity
- More accurate
Why do we breast biopsy?
- Need adequate tissue for dx
- Minimal scarring/disfurement
- allows for further therapy/re-excision
When would you do enteral access procedures?
- Feeding access
- Decompression
- Gastric Access
What are the two types of enteral access?
- Gastrostomy
- PEG
What is new-school vascular access?
Image guided techniques – more safe and more accurate
What is old school vascular access?
Use of only anatomic land marks
What does central access me?
IV with tip of catheter in a central vein like the internal jugular
What is a negative effect of central vascular access?
- TPN
Examples of Vascular Interventions
- Diagnostic
- Angioplasty/Stent for occlusive dz
- Embolization
- Tx of Aneurysmal Dz
- Dz Prevention
