| What is the name of the S-shaped portion of the internal carotid artery near the petrous portion of the temporal bone? | carotid siphon |
| List the two end branches of the internal carotid artery. | 1) anterior cerebral 2) middle cerebral |
| Which vessel carries deoxygenated blood to the lungs? | pulmonary artery |
| Which vessel carries oxygenated blood back to the L atrium of the heart? | pulmonary vein |
| Which part of the brain does the middle cerebral circulate blood to? | posterior brain |
| What vessel do the two vertebral arteries unite to form? | basilar artery |
| At what approximate level does the descending aorta pass through the diaphragm to become the abdominal aorta? | T12 |
| The vein most commonly used to draw blood at the elbow is the what vessel? | medial cubital |
| A common method or technique of introducing a needle and/or catheter into the blood vessel for angiographic procedures is called what? | seldinger technique |
| What are some common risks of an angiograph? | 1)embolus formation 2)dissection of a vessel 3)contrast media reaction |
| Which vessel is preferred for arterial vessel access for the majority of angiographic procedures? | femoral artery |
| What type of contrast is used for most angiographic procedures? | water-soluble; non-ionic |
| Generally where is the femoral artery punctured during an arterial catherization procedure? | just inferior to the inguinal ligament |
| What is the purpose of the heating device on an electromechanical injector? | 1)warms & maintains the contrast medium @ body temp. 2) reduces the viscosity of the contrast |
| Which vessel is most often catheterized for a pulmonary angiogram? | femoral vein |
| What type of catheter is often used to retrieve urethral stones? | ureteral stone baskets |
| What is the name of the vertebroplasty procedure to restore the collapsed portion of a vertebral body? | kyphoplasty |
| What is the interventional procedure for dissolving a blood clot? | thrombolysis |
| What procedure serves as a palliative measure for colonic structures due to inoperable neoplastic disease? | enteric stenting |
| What two arteries deliver blood to the heart muscle? | R & L coronary arteries |
| T/F: the right common carotid branches off of the brachiocephalic rather than the aortic arch. | true |
| The basilar artery rests upon the clivus of the _______bone. | sphenoid |
| T/F: the right subclavian artery arises directly from the aortic arch. | false; the L subclavian does |
| T/F: The cephalic vein is most commonly used for venipuncture. | false; medial cubital is most common |
| What factors affect the injection flow rate of an automatic electromechanical injector? | vessel size; viscosity of contrast; catheter length; catheter diameter; injection pressure; heating device; high pressure mechanism; control panel |
| What is the pathology when there is narrowing of the vessels? | vascular stenosis |
| What is the difference between a thrombus and an embolus? | embolus= free floating blood clot thrombus= blood clot attached inside vessel wall |
| What are the four major arteries that supply blood to the brain? | *R common carotid *R vertebral *L common carotid *L vertebral |
| What part of the body do the vertebral arteries supply blood to? | posterior circulation of the brain |
| What is another name for the Circle of Willis? | Arterial Circle |
| What is the difference between an arteriography and an angiocardiography? | *arteriography= imaging of the arteries *angiocardiography= imaging of heart and associated structures |
| What vessels are considered for catheterization? | *femoral *axillary *brachial *radial |
| What acts as a pipeline for transporting the contrast agent from an external source to a location within the body? | angiographic catheters |
| How many millimeters to a French? | 1mm= 3 French |
| What does a digitally subtracted image represent? | it takes away bone; removes all anatomy but the vessels of interest |
| When viscosity decreases; does this mean thicker or thinner? | thinner |
| What are some advantages to interventional procedures? | *less invasive & lower risk than traditional surgery *less cost *shorter hospital stay/recovery time *alternative for nonsurgical canidates |
| What happens in embolization procedures? | uses angiographic approach to create embolus in a vessel to restrict blood flow. |
| What is the interventional procedure when the goal is to reopen the lumen in a vessel and generally uses a double-lumen balloon-tipped catheter? | percutaneous transluminal angioplasty |
| What is a cagelike device that is placed in the lumen of a vessel to provide support? | stent |
| What interventional procedure prevents pulmonary embolism that is usually caused by deep vein thrombosis? | inferior vena cava filters |
| When putting in a inferior vena cava filter what vessel is used to have this in place? | jugular or femoral vein |
| What interventional procedure creates an artifical passageway for portal venous circulation? | transjugular intrahepatic portosystemic shunt (TIPS) |
| During angiocardiography, the catheter is advanced from the aorta into what? | L ventricle of the heart |
| The most common vascular approach during pulmonary arteriography is what vessel? | femoral vein |
| What is a device to extract urethral stones? | basket or loop |
| What is interventional procedure that involves intravascular administration of drugs? | infusion therapy |
| What is the procedure to dissolve blood clots? | thrombolysis |
| What is the technique to restrict uncontrolled hemorrhage snare catheter? | embolization |
