|---|---|
| This is a therapeutic procedure designed to dilate or reopen stenotic or occluded area in a vessel: | Percutaneous Transluminal Angioplasty |
| PTA: | Percutaneous Transluminal Angioplasty |
| PTA is often performed at the same time and through the same _____________ site as the initial _____________. | Catheterization; Angiogram |
| ___________ _____________ is used to dilate strictures in venous structures, ureters, and GI Tract. | Balloon Angioplasty |
| Balloon angioplasty is used to __________ strictures in __________ structures, ____________, and _____ ___________. | Dilate; Venous; Ureters; GI Tract |
| During Balloon Angioplasty a double lumen tube is used. One lumen allows for the passage of the ________ and ___________ and the other lumen does what? | Wire and Fluids; Communicates with the balloon on the distal end |
| During Balloon Angioplasty, the balloon is inflated with __________ __________ __________ for ________ to ______ seconds depending upon the ___________ of stenosis. | Diluted contrast medium; 15 to 45 seconds; Degree of stenosis. |
| After the Balloon has been inflated during Balloon Angioplasty what two options are there for the balloon? | Deflated and repositioned or withdrawn |
| What is performed after a balloon angioplasty to determine the success of the procedure? | A repeat angiogram using the initial cathertization. |
| Transluminal Angioplasty can be performed in which vessels? | Virtually any vessel that can be reached percutaneously with a catheter |
| What is the most common form of arterial stenosis treated by PTA? | Atherosclerosis |
| What is the best way to treat long segments of vessel occlusion? | Surgery |
| Balloon Angioplasty is not ___________ the plaque surrounding the vessel but instead it's ____________ the ___________ of the artery. | Compressing; enlarging the diameter |
| The typical reason for restenosis is the result of new ___________ of ____________ and not arterial wall ____________. | Deposits of plaque; not arterial wall collapse |
| In addition to Balloon Angioplasty, another new technique is percutaneous _____________ which _______________ the plaque. | Atherectomy; Micropulverizes |
| Another new technique are vascular ___________ which permanently remain in the vessel. | Stents |
| Where are most PTA procedures conducted? | Radiology Angiographic Suite |
| PTCA: | Percutaneous Transluminal Coronary Angioplasty |
| Where are most PTCA's performed and why? | In the Cardiac Cathetherization Lab because of potentially serious cardiac Complications |
| This is a procedure that involves therapeutic introduction of various substances to occlude or drastically reduce blood flow within a vessel: | Transcatheter Embolization |
| What are 3 main reasons for Transcatheter Embolization? | 1)Stops active bleeding sites 2)Control blood flow to diseased or malformed vessels (e.g., Tumors or AVMs) 3)To stop or reduce blood flow to an area before surgery |
| _____________ ___________ are used to temporarily reduce blood flow by constricting vessels. | Vasoconstricting Drugs |
| Coils are used to _____________ and are initially __________ as it is introduced into a catheter. | Occude; Straight |
| ______________ ____________ __________ are indicated for a patient with some type of ureteral or bladder blockage that causes ______________. | Percutaneous Nephrostomy Tube; Hydronephrosis |
| If urine is not eliminated from the kidney, _________ failure with _________ may occur as well as ___________. | Renal Failure; Necrosis; Sepsis |
| _____________ _________ is a catheter with multiple side holes at the distal end through which urine can enter and be drained. | Nephrostomy Tube |
| _____________ _____________ _________ is used to trap emboli to prevent _____________ embolism resulting from deep vein thrombosis from lower limbs. | Inferior Vena Cava Filter; Pulmonary Embolism |
| Inferior Vena Cava filters come in a __________ of shapes and delivered via a _____________ system. | Variety; Catheter |
| How are the Inferior Vena Cava filters shaped for use? | They assume their functional shape as they are released |
| _____________ _____________ is a comprehensive term used to describe a minor surgical procedure involving the introduction of special catheters into the ____________, __________ ____________ and ____________ ___________. | Cardiac Catheterization; Heart; Great Vessels; Coronary Arteries |
| During Cardiac Catheterization, both ____________ and ____________ treatments may be done in a single procedure. | Diagnostic and Therapeutic |
| Why is Cardiac Catheterization performed? | To identify the Anatomic and Physiologic condition of the heart |
| What is the most common disorder necessitating Cardiac Catheterization? | Coronary Artery Disease |
| Cardiac Catheterization procedures require ___________ ____________ exposure times for __________________ sequencing to capture motion. | Extremely short exposure times; Rapid-Exposure Sequencing |
| How many images (frames) are obtained during Cardiac Catheterization procedures? | 15 to 30 Frames/Sec |
| What kind of resolution is required during Cardiac Catheterization procedures and why? | High Resolution to image small structures |
| Storage requirements for Cardiac Catheterization procedures require _________ storage for ___________ amounts of ________ data. | Long-term; Large; Digital data |
| The radiographic examination of the Lymphatic System (Lymph Vessels and nodes) using contrast media is _____________. | Lymphography |
| The anatomy of the Lymphatic system contains ______ ____________ sets: Which are: | 2 Communicating Sets; Superficial and Deep |
| The Lymphatic System collects ________ from ____________ spaces and transports it to _____________________ system. | Collects fluid from tissue spaces and transports it to Blood-Vascular System |
| The Lymphatic System drains the collected fluid from tissue spaces into where? | The junction of the Left Subclavian and Internal Jugular Veins |
| Lymphography is primarily used today to assess the _____________ ____________ of ____________. | Clinical Extent of Lymphomas |
| Why is Lymphography seldom used today? | Because of advances in CT and MRI |
| The specific study of Lymph Vessels is ________________ and is carried out how soon after the injection of contrast material? | Lymphangiography; Within 1 hour after injection |
