INTERVENTIONAL RADIOLOGY Flashcards
is a subspecialty of radiology in which minimally invasive procedure are performed using image guidance
INTERVENTIONAL RADIOLOGY
a procedure to block coronary arteries by contrary artery disease; refer to replacing blood vessels
angioplasty
where gas exchange takes place
alveolar sac
there’s a one way flow of blood; some babies have hole in the heart
tetralogy of fallout
what are some common procedures in interventional radiology
-angiography
-balloon angioplasty/ stent
-chemoembolization
-cryotherapy/cryoablation
-drain insertion
-thrombolysis
-embolization
-biopsy
-radio frequency ablation RFA/RF
-line insertion/ vascular access
-IVC filters
-vertebroplasty/ kyphoplasty
-radiologically inserted gastronomy (RIG)
-DIALYSIS
-transjugular intrahepatic porto- systemic shunt (TIPS)
-biliary intervention
-endovenous laser ablation of varicose veins
water in the kidney
hydrothrombosis
branching kidney stone; most common problem in the kidney
staghorn calculus
swelling of 1 or 2 kidneys
hydronephrosis
tests that uses xray to look at the bladder, uterus, and kidneys
retrograde pyelogram
the negative in a contrast media
air
the positive in a contrast media
iodinate (iodine)
is the imaging of the blood vessels to look for abnormalities with the use of various contrast media including iodinated contrast, gadolinium-based agents & CO2 gas
angiography
refers to brightness (sanag)
radiopaque
refers to dark (lasaw)
radiolucent
used so that we can see what’s inside the body
insert contrast
to investigate anatomic variances; to evaluate motion of a part; to evaluate suspected tumors
angiography
what are the types of angiography
-visceral angiography
-peripheral angiography
-anteriography
-venography
this is used to know the pathology & anatomy
contrast media
indication of contrast media is to:?
-identify the anatomy and pathology process in the blood vessels
-to evaluate claudication
-to look for vascular stenosis or occlusion (blockage/hollow organ)
-to detect and verify the existence & exact position an intracranial vascular lesion (brain)
what are the co-indications:?
-creatinine/ BUN
-blood pressure (hypertensive/hypotensive)
-pregnant
-patient refusal
-undergoing other procedures (e.g. kemotherapy)
an agent used before as a contrast media
chalk
who produced the first radiograph of the blood vessels of an amputated hand?
Haschek & Linderthal
when was the first radiograph of the blood vessels of an amputated hand produced?
January 1896
what year did researchers used sodium iodide as contrast media in lower limb?
1920
what year when contrast medium injected through a needle that punctured the vessel/ through a catheter inserted through a peripherally exposed vessel
1950s
when was the development of a flexible thin-walled catheter was made?
1952
what is called to the development of a flexible thin-walled catheter
Seldinger technique
refers to the developement of casette changes, roll film changer, cut film changer and line & serial spot filming/ digital devices
serial imaging
refer to as organic iodide solutions
contrast media
what is the effect of a contrast media
-peripheral vasodilation
-decreased blood pressure
-cardio toxicity
-may also produce nausea and an uncomfortable burning sensation
-may involve an allergic reaction
an effect in contrast media that has a slightly difficulty in breathing
minor
an effect of contrast media that has effect of shock and loss of conciousness
severe
what is the typical amount of iodine concentrations used in cerebral and limb angiography?
30%
it distribute oxygenated blood i the body
arteries
concentration for visceral angiography
35%
concentration of lower of peripheral renography
30%
agents that has higher concentration
iodine agents
agents that are more viscous and produce greater resistance in the catheter during injection
non-ionic agents
it is less radiopaque than blood and appears as a negative or void in angiographic imaging
CO2
presence of air or gas in the abdominal (peritoneal cavity)
pneumoperitoneum
may be used as an alternative contrast media
gadolinium
the primary contrast agent in MRI
gadolinium
contrast media that is less radiopaque than iodine
gadolinium
narrow window are used
digital subtraction angiography
