Image Guided Procedures Flashcards
What do we use image guided interventions for?
drainage vascular access biopsy enteral access vascular interventions
What are different draining types of pleural fluid?
simple effusion
loculated emphyma
chylothorax
hemothorax
What are the methods of drainage?
blind percutaneous
image based
situational
Why use image guidance?
smaller tubes
less if any incisions
more precise
Why are biopsies important?
need adequate tissue for diagnosis
minimizes scarring or disfigurement
allows for further therapy, including re-excision
What are the least invasive and most invasive biopsies?
needle aspiration
excisional biopsy
What is important about using imaging for vascular abscesses?
Allows you to use a larger size with more precision and thus allowing you to use more volume and be faster
What is the old school way for vascular access?
Used only land marks
What are the adjuncts of vascular abscess?
IVC filters may reduce fatal PE in certain patients, placed through large vein (IJ, femoral)
Now removable
What is a venography used for?
to locate renal veins and shoot dye to see where they are)
What leads to better outcomes from surrgey?
early feedings of the gut
How do you put in feeding tube?
If not operating on the gut, you put in a PEG (percutaneous gastrostomy tube) - go through the esophagus to the stomach, push stomach to anterior abdomen and someone outside will see the light reflex and insert needle
What is the seldinger technique?
insert needle into femoral artery, place wire through the needle, remove the needle, place large sheath/ catheter over wire
Angiography tips
take digital subtraction angiography
use intra-arterial contrast
manipulate wires, catheters to areas of pathology, then can either place balloon or stent if applicable but not if you have your dx and can do surgery
What is embolization typically done for?
bleeding
