IR 3 Venous Flashcards
(39 cards)
What is the superior vena cava a common site placement for?
Central lines (SVC/RA junction)
What are the superficial veins of the upper extremity?
Cephalic, Basilic, Median Cubital
What is the longest vein in the body?
The great saphenous vein
Describe the pathway of the great saphenous vein
Extends from foot along medial aspect of leg to thigh where it becomes the femoral vein
Describe the pathway of the small saphenous vein
Originates from the foot and extends posteriorly along the leg terminating at the knee where it becomes the popliteal vein
What are the major deep veins in the lower extremity
Posterior tibial, peroneal, anterior tibial, popliteal, femoral
Name the semi permanent venous catheters positioned near the right atrium
PICC, Hickman, Subcutaneous Port
What are the common reason for the insertion of venous access devices
To administer chemotherapy
To administer large dose of antibiotics
For frequent blood testing
What is a tunneled type of central venous catheter?
for long term use
tunneled subcutaneously through the skin to exit a different location
typically cuffed and adheres to the subcutaneous skin to prevent movement and infection
What are different types of central venous catherters?
tunneled dialysis catheters
hickman
picc lines
what are non-tunneled central venous catheters
for short term suage
direct access to vein
what are types of non tunneled central venous catheters
mahurkar
picc
What are subcutaneous central venous catheters
small ports placed subcutaneously for long term use
accessed into vein and catheter is tunneled subcutaneously through the skin to exit site
catheter is connected to a port which is indwelling subcutaneously
What is a PICC/Peripheral Inserted Central Catheter
Single, dual, or triple lumen
Designed for blood draws, intravenous fluids,
and medication infusion. Power contrast
injections for CT/MR
What is used to extract foreign bodies?
Loop snares, basket
catheters, and grabbing
forceps are used to
retrieve:
What would indicate that a patient should have a IVC Filter placement?
patients with
a high risk of developing
DVT or a history of
reoccurring pulmonary
emboli
what does an IVC Filter do?
Traps thrombus from the
lower extremities from
becoming potentially fatal
emboli in the lungs
Prevents blood clots from reaching the lungs
what is a thrombus?
a blood clot that forms inside a blood vessel
What is varicose veins?
Dilated, tortuous veins, usually
involving the superficial veins
Primarily involves lower
extremities and is a principal
source of potentially lethal
pulmonary embolism.
How does varicose veins happens?
Increased blood volume in
affected areas can cause
phleboliths and calcified clots.
Deep vein thrombosis (clot in
vein), may cause pain,
inflammation and swelling of
vein.
What happens in a venous ablation?
Tissue around vein is
numbed with tumescent
Catheter is inserted into
vein
Probe tip is heated
(Radiofrequency) or laser
is emitted until vein tissue
is destroyed and vein
closes
Where is the Inferior Vena Cava (IVF) located when referring to the placement associated to the spine?
On the lateral side of the spine
list the veins from superior to inferior that extend from the inferior vena cava
hepatic, renal, common iliac
where do the splenic, inferior mesenteric, and superior mesenteric vein drain into?
the portal vein
