What is percutaneous transluminal coronary angioplasty (ptca)?

What is percutaneous transluminal coronary angioplasty (ptca)?

Heart vessel therapy: Percutaneous transluminal coronary angioplasty (PTCA) is the opening of blocked heart arteries with a balloon. An artery is stuck and a wire is passed in the system until reaching the heart arteries. A balloon is passed over the wire to the area of blockage and inflated. The blockage is flattened but it can return. So most patients actually get stents placed. Stents require blood thinners. ...Read more

Percutaneous (Definition)

In surgery, percutaneous pertains to any medical procedure where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an "open" approach where inner organs or tissue are exposed (typically with the use of a scalpel). The percutaneous approach is commonly used in vascular procedures. This involves a needle catheter getting access ...Read more

What is pcnl (percutaneous nephrolithotomy)?

What is pcnl (percutaneous nephrolithotomy)?

PCNL: Minimally invasive surgery for removal of large kidney stone/s. Nephrostomy tube (catheter) is placed in kidney thru skin in back or flank, either under local anesthetic & with sedation or general anesthesia day before or day of procedure. Then nephroscope (kidney telescope) passed thru catheter channel, stone is visualized & broken up with laser or percussion "gun" & fragments are irrigated out. ...Read more

Whats percutaneous cholecystectomy? Whats transhepatic biliary catheter? Whats biliary stent? Are they effective alternatives to a cholecystectomy?

Whats percutaneous cholecystectomy? Whats transhepatic biliary catheter? Whats biliary stent? Are they effective alternatives to a cholecystectomy?

Possibly: Percutaneous cholecystostomy is a tube placed through the skin into the gb for drainage. Thbc is a tube passed through the skin, the liver, and into the bile duct system, a form of biliary stent. Some stents can be passed into the lower duct using an endoscope through the stomach. Any may be necessary in some cases, but cholecystectomy would be the gold standard in most cases. Good luck. ...Read more

What is percutaneous nephrolithotomy?

What is percutaneous nephrolithotomy?

Via tube in kidney: Placement of nephrostomy tube through flank into kidney. Then passing a nephroscope (operating telescope for kidneys) through nephrostomy tube and breaking up or pulverizing kidney stone mechanically, by laser or ultrasound by a probe through the nephroscope. Procedure is performed under direct observation via a camera attached to the nephroscope telescope. ...Read more

Is lithotripsy better or percutaneous nephrolithotomy better?

Is  lithotripsy better or percutaneous nephrolithotomy better?

It depends: Larger (>20 mm or >10-15 mm in lower pole) stones are probably best treated via percutaneous approach (pcnl). Shockwave lithotripsy (swl) may be less invasive for smaller stones. Swl (and ureteroscopy) may be combined with pcnl to remove all stone material. Pcnl typically requires inpatient hospitalization, more pain, risk of bleeding, but is more likely to result in complete stone clearance. ...Read more

Robotic assisted cornary artery bypass sugery?

Robotic assisted cornary artery bypass sugery?

Remote surgery: Bypass surgery done through tubes or scopes in which the surgery operates by sitting at a console and operates the scopes or tubes remotely. Much less invasive in that the cutting of the sternum or breastbone is not needed. The disadvantage is that it cannot reached all areas of blockage in some patients. ...Read more

Does endoscopic retrograde cholangiopancreatography work?

Does endoscopic retrograde cholangiopancreatography work?

Absolutely: An ERCP is a test used to diagnose obstructions of the bile duct system. Sometimes an ERCP can be used to dislodge a gallstone stuck in the main bile duct. Sometimes a stent can be placed via ERCP into the main bile duct to relieve pressure as in an obstructing cancer. Ercp is one of the truly amazing advances endoscopic medicine has allowed. ...Read more

Whats safer: coronary angiogram or CT angiogram?

Whats safer: coronary angiogram or CT angiogram?

Ct vs cath: In simplest terms the ct angiogram would be safer than a coronary angiogram, however, they are usually used in different circumstances. The ct angiogram is useful as a screening tool to see if coronary disease is present. A cardiac catheterization is performed when a patient has an acute coronary syndrome or a myocardial infarction to evaluate coronary disease, or even treated. ...Read more

Is stenting or carotid endarterectomy better?

Is stenting or carotid endarterectomy better?

Carotid intervention: CEA has lower stroke risk than stent, stent has lower risk of MI and cranial nerve injury. Each suitable at times. Best to go to provider that can do either. CEA generally better for standard risk patients, stent generally best if patient has had neck radiation, tracheostomy, or prior CEA. Can get biased view if provider can only do one or the other. Go to someone that can advise on risk/benefit. ...Read more

Is the percutaneous transhepatic cholangiography a risky thing to do?

No, but...: There are less invasive ways to image the biliary tree, like ultrasound, ERCP (by a gastroenterologist) and mrcp (mri). If there is some blockage, drainage can usually be achieved by a gastroenterologist, with percutaneous drainage reserved for cases that cannot be treated by a gastroenterologist. While percutaneous biliary imaging and interventions do not have high risk, less risky options exist. ...Read more
