Catheter Vs Stent
A catheter is a thin plastic tube that is inserted into the body to obtain fluids/blood or give medicine. So some catheters can be placed in the veins and medicine given directly into the body, IV fluids given or blood sampled. A catheter can be placed in the bladder ...Read more
Dilation of blockage: Using a vascular catheter, not an open surgical procedure, a balloon is used to dilate a blocked artery. This may be followed by placing a stent, a metal alloy support scaffold, can be placed to hold the vessel open. Aggressive medications will be needed to control the risk factors that contributed to the blockage. ...Read more
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 moreSee 1 more doctor answer
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
No: A Malecot catheter is more typically used to drain the kidney via a passage through the back or the bladder through a suprapubic passage. It has soft extended flanges at its tip to help hold it in place. A Foley catheter has a smooth rounded tip and is inserted into the urethra to drain the bladder ...Read more
What is likelyhood of having heart attack or angina after angioplasty (balloon) & stent placed on main artery?
Angioplasty/stent : Heart attack is not necessarily prevented by angioplasty or stent. We do treat the underlying disease aggressively as well as dual anti platelet therapy to prevent stent thrombosis. If you smoke it negates much of the treatment. Most people do well after angioplasty and stenting. ...Read moreSee 1 more doctor answer
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
Renal Angioplasty: Angioplasty is balloon revascularization. Usual approach is 2mm incision in the femoral artery at groin, sheath inserted, followed by the cannulation of the artery with a catheter. Dye is injected to locate area in need of angioplasty. Balloon over a wire via the catheter & when in place is inflated to an appropriate pressure. The balloon is removed and then stent deployed and inflated at stenosis. ...Read moreSee 1 more doctor answer
Yes: Is not possible to have bypass surgery without first having cardiac catheterization. The surgeon requires a detailed picture of the coronary anatomy to know if the patient is suitable for bypass surgery and to know where to put the bypass grafts during the operation. ...Read moreSee 1 more doctor answer
