| catheterization | Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from intubation in that the tube here is used to restore or maintain patency in obstructions. (12 Dec 1998) |

| catheterization, central venous | Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, haemodialysis, or hyperalimentation. (12 Dec 1998) |
| catheterization, peripheral | Insertion of a catheter into a peripheral artery, vein, or airway for diagnostic or therapeutic purposes. (12 Dec 1998) |
| catheterization, swan-ganz | Placement of a flow-directed catheter (developed by cardiologists swan and ganz) for measuring pulmonary arterial pressures. The catheter is introduced into the venous system via the basilic, internal jugular, or subclavian vein, and is guided by blood flow into the superior vena cava, the right atrium and ventricle, and into the pulmonary artery. (12 Dec 1998) |
| heart catheterization | Procedure which includes placement of catheter, recording of intracardiac and intravascular pressure, obtaining blood samples for chemical analysis, and cardiac output measurement, etc. Specific angiographic injection techniques are also involved. (12 Dec 1998) |
| differential ureteral catheterization test | A study performed to determine various functional parameters of one kidney compared to the contralateral kidney; ureteral catheters are inserted at cystoscopy into the ureter or renal pelvis bilaterally, and simultaneous measurements are made of urine flow rate, insulin, or PAH (if infused), endogenous creatinine, or various urinary solutes. Synonym: differential renal function test, split renal function test. (05 Mar 2000) |
| urinary catheterization | Employment or passage of a catheter into the bladder (urethral c.) or kidney (ureteral c.) for therapeutic or diagnostic purposes. (12 Dec 1998) |
| cardiovascular | <cardiology, physiology> Pertaining to the heart and blood vessels. (18 Nov 1997) |
| cardiovascular abnormalities | Congenital structural abnormalities of the cardiovascular system. (12 Dec 1998) |
| cardiovascular agents | Agents that affect the rate or intensity of cardiac contraction, blood vessel diameter, or blood volume. (12 Dec 1998) |
| cardiovascular deconditioning | A change in cardiovascular function, especially after periods of actual or simulated weightlessness or diminished power or strength, probably related to the shift of a quantity of blood from the lower limbs to the thorax, resulting in reflex diuresis and a reduction of blood volume. (12 Dec 1998) |
| cardiovascular physiology | Functions and activities of the cardiovascular system as a whole or of any of its parts. (12 Dec 1998) |
| cardiovascular radiology | The clinical subspecialty of radiology concerned with diagnosis and treatment of diseases of the vascular system. (05 Mar 2000) |
| cardiovascular surgery | The use of surgery to fix disorders of the heartand/or blood vessels. (09 Oct 1997) |
| cardiovascular surgical procedures | Surgery performed on the heart or blood vessels. (12 Dec 1998) |
