Interventional Radiography Flashcards
State the differences between radiology department fluoroscopy units and interventional / cardiology fluoroscopy units
- Intervention / Cardiology Fluoroscopy Units are floor or ceiling mounted
- They are highly modern and motorised
- They are isocentric meaning they can move around a fixed central point and prevents having to move the patient
- Built in dose monitoring
- Has several monitors to allow for HD projection from multiple angles to be viewed
- Radiolucent specialised patient table for minimal x-ray absorption
What is Interventional Radiology
- an area which uses x-ray guided techniques to repair, seal-off or unblock anatomy
- Utilises the body’s vascular system to access multiple areas, from head to toe
What is the Catheterisation Laboratory
- An area which uses x-ray guided techniques however, it focuses on the heart and specifically its vessels
What is the role of Interventional Radiology
- Enables targeted treatment to be given instead of open surgery which in turn allows patients to either attend as an outpatient or have a one-night stay to recover
What is the major advantage of Interventional Radiology
- Minimally invasive procedures
What are the advantages of Interventional Radiology
- Live imaging allows intra-procedural targeting of anatomy and device delivery
- Much less invasive and risky surgery
- Lower costs to NHS
- Quicker, Local Anaesthetic, home!
- May not require any follow up
What are the disadvantages of Interventional Radiology
- Radiation Dose
- Risk of Infection
- Risk of PE and Stroke
- Haemorrhage at site of intervention
- Rupture or Dissection of Blood Vessels
- Pneumothorax
What are examples of Interventional radiology procedures
- Percutaneous Coronary Intervention (PCI)
- Valve Replacement
- Cardiac Ablation
- Endovascular Procedures
- Stenting
- Biopsy
- Angioplasty
Where is the main access point for Vascular access
- Femoral Artery
What are other access points for vascular access
- Radial then Brachial Artery
Why would Aspirin be used in a Cardiac Procedure?
- Given to the patient to prevent any further blood clots from forming
Why would GTN (Glyceryl Trinitrate) be used?
- Given as a vasodilator to relax the arteries and allow greater blood flow
Name imaging positions used during cardiac procedures
- PA Craniocaudal
- PA Caudocranial
- Right Anterior Oblique
- Left Anterior Oblique
- Lateral
Who is in the Cath Lab?
- Consultant Interventional Cardiologist
- Registrar On-Call
- Radiographer
- Cardiac Physiologist
- Staff Nurse On-Call
- Students
Define Absorbed Dose
- Defined as the amount of radiation required to deposit 1 joule (J) of energy in 1 kilogram of any kind of matter
