Percutaneous Health Dictionary

A treatment for a stenosed (restricted) coronary artery (see ARTERIES). A balloon-tipped catheter (see CATHETERS) is passed through an incision in the skin of the chest into the artery of the HEART that has developed stenosis (narrowing). The balloon is aligned with the stenosed section and then in?ated to dilate the coronary artery and allow the blood to ?ow more freely.... percutaneous transluminal coronary angioplasty

A technique for displaying the bile ducts (see BILE DUCT) and pancreatic ducts (see PANCREAS) with radio-opaque dyes. These are introduced via a catheter (see CATHETERS) inserted into the ducts through an incision in the skin. An X-ray is then taken of the area.... percutaneous transhepatic cholangiopancreatography (ptc)

(PCI) treatment of coronary artery disease delivered by cardiac *catheterization. This usually means *coronary angioplasty followed by insertion of a coronary *stent, but also includes more specialized procedures, such as rotational *atherectomy (rotablation). Primary PCI refers to the use of PCI as the first-line treatment to relieve coronary obstruction in S-T elevation *myocardial infarction, rather than *thrombolysis. Rescue PCI is used in the event of unsuccessful thrombolysis.... percutaneous coronary intervention

see PESA.... percutaneous epididymal sperm aspiration

(PCNL) a technique of removing stones from the kidney via a *nephroscope passed into the kidney through a dilated track established from the skin surface into the renal pelvis.... percutaneous nephrolithotomy

imaging of the bile duct and pancreatic duct. A catheter is carefully manipulated into the ducts via direct puncture through the abdomen under radiological guidance. Contrast material is flushed through the catheter to delineate the ducts (see also cholangiography). This procedure is often performed in cases of obstructive jaundice prior to insertion of a biliary drain or stent when *ERCP is not possible.... percutaneous transhepatic cholangiopancreatography
