| percutaneous | <technique> Performed through the skin, as injection of radiopacque material in radiological examination or the removal of tissue for biopsy accomplished by a needle. Origin: L. Cutis = skin (18 Nov 1997) |
|---|---|
| percutaneous absorption | The absorption of drugs, allergens, and other substances through unbroken skin. Synonym: cutaneous absorption. (05 Mar 2000) |
| percutaneous cholangiography | Radiography of the biliary system after introduction of contrast medium by introducing a needle through the skin inferior to the right costal margin, and inserting it into the substance of the liver or into the gallbladder. (05 Mar 2000) |
| percutaneous nephrostomy | Drainage of the collecting system through a catheter inserted through the skin of the flank under fluoroscopic control, usually using the Seldinger technique. (05 Mar 2000) |
| percutaneous stimulation | Electrical stimulation of the peripheral nerves or spinal cord by the application of electrodes to the skin. (05 Mar 2000) |
| percutaneous transhepatic cholangiography | Contrast radiographic examination of biliary system performed by injection through a percutaneously placed needle inserted into an intrahepatic bile duct. (05 Mar 2000) |
| percutaneous transluminal angioplasty | An operation for enlarging a narrowed vascular lumen by inflating and withdrawing through the stenotic region a balloon on the tip of an angiographic catheter; may include positioning of an intravascular stent. (05 Mar 2000) |
| percutaneous transluminal coronary angioplasty | Percutaneous transluminal angioplasty of coronary artery or arteries. (05 Mar 2000) |
| percutaneous umbilical blood sampling | See: PUBS. (12 Dec 1998) |
| nephrostomy, percutaneous | The insertion of a catheter through the skin and body wall into the kidney pelvis, mainly to provide urine drainage where the ureter is not functional. It is used also to remove or dissolve renal calculi and to diagnose ureteral obstruction. (12 Dec 1998) |
| diskectomy, percutaneous | Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by hijikata in japan in 1975. In 1985 onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anaesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis. (12 Dec 1998) |
| transluminal percutaneous coronary angioplasty | <cardiology, procedure> Dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply. (07 Mar 2000) |
| adrenal angiography | <radiology> Adrenal arteriography, 3 arteries: superior - inferior phrenic a., middle - aorta, inferior - renal a., difficult to inject all 3; arteriography usually not attempted adrenal venography, venous sampling, may define anatomy, may rupture capsule and ablate function (12 Dec 1998) |
| angiography | <investigation> A radiographic technique where a radio-opaque (shows up on X-ray) contrast material is injected into a blood vessel for the purpose of identifying its anatomy on X-ray. This technique is used to image arteries in the brain, heart, kidneys, gastrointestinal tract, aorta, neck (carotids), chest, limbs and pulmonary circuit. (27 Sep 1997) |
| angiography catheter | A thin-walled tube suitable for percutaneous puncture and powered injection of contrast media for radiography; catheter diameter is measured on the French scale. (05 Mar 2000) |
