| Answer |

|
| Angiography |
the radiographic study of vascular structures after the introduction of contrast |
| Arteriography |
radiologic examination of the arteries via contrast injection |
| Arterioslerotic |
pathologic condition characteristic of thickening and hardening of arterial walls, leading to general loss of elasticity. |
| Arteriovenous malformation |
abnormal anastomosis or communication between an artery and vein. |
| Guidewire |
tightly wound metallic wire over which angiographic catheters are placed |
| Ischemic |
indicative of local decrease in blood supply to myocardial tissue associated with temporary obstruction |
| Portal circulation |
system of vessels carrying blood from organs of digestion to the liver |
| Venography |
radiographic examination of veins via contrast injection |
| Stenosis |
narrowing of a vessel |
| Occlusion |
blockage of a vessel |
| Contrast media used for angiographic studies |
opaque contrast containing organic iodine solutions |
| What is done for patients with predisposition to a severe reaction to contrast? |
CO2 is used |
| What contrast is primarily used for MRI? |
gadolinium |
| Explain the Seldinger method |
both walls of the vessel are pierced, the needle is retracted, guidewire is inserted and traction is held while the needle is removed and replaced with the catheter. |
| What form of anesthesia is used for catheterization? |
local |
| The entire program for cerebral angiography takes how long? |
7-10 seconds |
| What is the injection rate for cerebral angiography? |
5-9mL/sec for 1-2 sec |
| What is the most definitive procedure for visualizing the coronary anatomy? |
coronary angiography? |
| Complications for cardiac cath: |
vasovagal reaction, stroke, heart attack, death, bleeding at puncture site, nerve, vessel or tissue damage, allergic reaction. |
| Purpose for pulmonary arteriography |
evaluation of pulmonary embolic disease |
| Vessels demonstrated during pulmonary arteriography include: |
pulmonary arteries, R atrium, L ventricle, Thoracic aorta |
| Purpose for cerebral angiography |
investigate intracranial vascular lesions (aneurism, AVM, tumor, atherosclerosis, stenosis) |
| Percutaneous transluminal angioplasty |
therapeutic procedure used to dilate or reopen stenotic or occluded area of a vessel |
| Balloon angioplasty is used to: |
dilate strictures in venous structures, ureters and GI tract. |
| Indications for cardiac cath |
obstructive coronary artery disease, thrombus formation, coronary artery collateral flow, coronary anomalities, aneurisms, spasms, artery size. |
| Most common catheter introduction site for cardiac cath: |
femoral artery |
| Secondary catheter introduction site for cardiac cath: |
radial, brachial, axillary, jugular, subclavian |
| General indications for cardiac cath: |
identify anatomic and physiologic conditions of the heart |
