| Question | Answer |
|---|---|
| aneurysmectomy | surgical excision of an aneurysm |
| bone marrow transplant | infusion of normal bone marrow cells from a donor with matching cells and tissue to a recipient with a certain type of leukemia or anemia |
| cardiac pacemaker | battery-powered or nuclear-powered apparatus implanted under the skin to regulate heart rate |
| coronary artery bypass graft (CABG) | surgical technique to bring a new blood supply to heart muscles by detouring around blocked arteries |
| defibrillation | application of an electric shock to the myocardium through the chest wall to restore normal cardiac rhythm |
| embolectomy | surgical removal of an embolus or clot |
| femoropopliteal bypass | surgery to establish an alternate route from femoral artery to popliteal artery to bypass obstructive portion |
| hemorrhoidectomy | excision of hemorrhoids, the varicosed veins in the rectal region |
| intracoronary thrmobolytic therapy | an injection of a medication in a blocked coronary vessel to dissolve blood clots |
| laser angioplasty | the use of light amplicfication by simulated emission of radiation or laser beam to open blocked arteries especially in lower extremities |
| mitral commissurotomy | surgical procedure to repair a stenosed mitral vlave by breaking apart the leaves (commissures) of the valve |
| percutaneous transluminal coronary angioplasty (PTCA) | procedure in which a balloon is passed through a blood vessel to the area in which plaque is formed. Inflation of the balloon then flattens the plaque against the vessel wall and allows the blood to circulate more freely. |
| vein ligation and stripping | surgical method of tying off a varicose veing and removing it |
| cardiac catherterization | introduction of a catheter into the heart by way of a blood vessel for the purpose of determining cardiac disease |
| cardiac scan | @D photographic representation of the heart taken after the introduction of radioactive material into the body |
| Doppler flow studies | study that uses ultrasound to determine the velocity of the flow of blood within the vessels |
| impedance plethysmography | measures venous flow to the limbs using a plethymograph, which records electrical resisstance (impedance) caused by venous occlusion. Used to detect deep vein thrombosis |
| sphygmomanometer | device used for measuring arterial blood pressure |
| treadmill stress test | test to assess the ability of the coronary circulation to handle the increased load placed on the heart by exercise |
| complete blood count | basic blood screening that includes tests on hemoglobin, hematocrit, red blood cell morphology; leukocyte count, and WBC's types |
| coagulation time | blood test to determine the time it takes for blood to form a clot |
| hemoglobin (Hgb) | oxygen-carrying components in red blood cells, responsible for giving blood its color |
| prothrombin time (PT) | test to determine certain coagulation activity defects; also used to monitor anti-coagulation therapy |
| bone marrow biopsy | needle puncture to remove bone marrow for study, usually from the sternum or ilium, to determine certain blood cell diseases, such as leukemia and anemia |
| auscultation | the hearing of sounds within the body through a stethoscope |
| blood pressure (BP) | pressure exerted by the blood against the blood vessel walls |
| cardiopulmonary resuscitation (CPR) | emergency procedure consisting of artificial ventilation and external cardiac massage |
| diastole | phase in the cardiac cycle in which the ventricles relax between contractions |
| extracorporeal | occurring outside the body |
| extravasation | escape of blood from the blood vessel into the tissue |
| heart murmur | a short duration humming sound of cardiac or vascular origin |
| hypertension | blood pressure that is above normal |
| hypotension | blood pressure that is below normal |
| lumen | space within a tubular part or organ, such as the space within a blood vessel |
| occlude | to close tightly |
| percussion | tapping of a body surface with the fingers to determine the density of the part beneath |
| peripheral vascular | referring to the blood vessels outside the heart and the lymphatic vessels |
| systole | phase in the cardiac cycle in which the ventircles contract |
| vasconstrictor | agent or nerve that narrows the lumen of blood vessels |
| vasodilator | agent or nerve that enlarges the lumen of blood vessels |
| venipuncture | puncture of vein to remove blood, instill a medication, or start an intravenous infusion |
| anticoagulant | abnormal or pathological condition of the blood |
| hemorrhage | rapid flow of blood |
| manometer | instrument used to measure the pressure of fluids |
| plasma | liquid portion of the blood in which the elements or cells are suspended, and which also contains some of the clotting factors |
| serum | liquid portion of the blood without the clotting factors |
