| 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) |
| pregnancy, tubal | Ectopic pregnancy within an oviduct. (12 Dec 1998) |
| sterilization, tubal | Surgical interruption of the fallopian tube during laparotomy or in the context of pelvioscopy. (12 Dec 1998) |
| tubal | Relating to a tube, especially the uterine tube. (05 Mar 2000) |
| tubal abortion | The rupture of an oviduct, the seat of ectopic pregnancy, or extrusion of the product of conception through the fimbriated end of the oviduct; aborted ectopic pregnancy, the pregnancy having originated in the fallopian tubes. Synonym: aborted ectopic pregnancy. (05 Mar 2000) |
| tubal air cells | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
| tubal branch | Branch to a tubular structure. Synonym: ramus tubarius. (05 Mar 2000) |
| tubal branch of the tympanic plexus | Sensory branch of tympanic plexus (of glossopharyngeal nerve) to auditory tube. Synonym: ramus tubarius plexus tympanici. (05 Mar 2000) |
| tubal branch of the uterine artery | <anatomy, artery> Terminal branch of uterine artery (with ovarian branch) supplying medial portion of uterine tube, anastomosing with tubal branch of ovarian artery. Synonym: ramus tubarius arteriae uterinae. (05 Mar 2000) |
