Which material gas (name of gas) or liqiud (name of dye) is used for to inflate baloon for ballon angioplasty?

Answer 1

It is a radio-opaque dye which can be seen on Xray, like Conray or Hipaque. The cather is positioned and the dye used to inflate balloon so that the amount of inflation can be seen and controlled on Xray.

Answer 2

Angioplasty (AN'je-o-plas-te) refers to a procedure to change or widen blood vessels, usually blood vessels narrowed or constricted by the build-up of atherosclerotic plaque. Coronary angioplasty techniques do not require opening the chest or the heart, but instead uses a catheter (KATH'e-ter) to enter the heart via the circulatory system.

Currently this procedure is not performed at the Centenary Health Centre of the Rouge Valley Health System. Arrangements can be made for this to be performed at a nearby hospital. The hospitals in this area that perform these procedures include:

* St. Michael's Hospital
* Sunnybrook Health Sciences Centre
* The Toronto General Hospital


How it's done

Like coronary angiography angioplasty begins by accessing the circulatory system via an artery in the groin or wrist. A tube or catheter is advanced towards the heart. A guide wire is then advanced beyond an area of narrowing. A baloon is advanced over the wire and inflated, opening the artery. The baloon, wire and catheter are removed and the puncture site are sealed with temporary pressure.


Advantages

Angioplasty can be performed under local anaesthesia. Recovery is shorter and less painful than surgery (and there are no scars). The procedure is quicker and less expensive than surgery.

The results are often impressive.

Angioplasty is Not for Everyone

Angioplasty is not for everyone, however, it is generally used only for single-or double-vessel disease (i.e., blockages in one or two coronary arteries). It is less efficient if there are many points of blockage in a single artery and may not be effective if the plaque is calcified or hardened. Some locations can't be reached by a catheter (for example, a blockage where the artery turns or narrows so badly that the catheter can't get through). Angioplasty can't stop the disease of atherosclerosis, and reblockage of widened arteries remains a major drawback. Because arteries may "renarrow" (restenosis), some people may require two or more procedures. There is currently extensive research underway to reduce the renarrowing. Stents, local irradiation and medication may be helpful.


Types of Angioplasty

Balloon Angioplasty or Percutaneous Transluminal Coronary Angioplasty (per"ku-TA'ne-us trans-LU'min-al KOR'o-na-re AN'je-o-plas-te) or PTCA:

As its name implies, this type of angioplasty utilizes a small balloon to widen an obstructed artery. A narrow tube called a catheter (KATH'e-ter) is guided from a small incision in the arm or leg through the body and into the heart. When the guide wire is in place at the area of coronary blockage, a balloon tip is inserted into the catheter. The balloon tip is inflated with carefully controlled pressure, compressing the plaque up against the walls of the artery. When it appears that the diameter (or lumen) of the artery is sufficiently widened, the balloon is deflated and the catheter withdrawn.

In about 90% of patients, balloon angioplasty immediately improves blood flow in the dilated coronary artery. As a result, angina (chest pain) is reduced and the risk of heart attack in this artery decreased. The morality rate for this procedure is very low (about 1%). The biggest problem at this time is re-closure of the dilated artery. In about 25% of patients who have a successful angioplasty, the dilated artery renarrows (restenosis) within the first six months. Fortunately should this occur a heart attack is very unlikely. Often the artery can be retreated with angioplasty, usually with a good long term result.

Laser Ablation

In this form of angioplasty, once the catheter is in place at the site of coronary blockage, a laser tip is inserted. The laser tip essentially melts through the layers of atherosclerotic plaque by converting the plaque into gaseous products and microscopic particles. Although conceptually attractive this form of therapy has been disappointing and in general no better than regular angioplasty.


Atherectomy (ATH'er-Ek-To-Me) Or Router Angioplasty

Another experimental approach to reopening narrow coronary vessels is atherectomy. This procedure uses a rotary device (a high speed cutting drill mounted on a catheter) that literally shaves off plaque from the artery wall. Although conceptually attractive this form of therapy has been disappointing and in general is only used under very specific circumstances.


Stents:

Stents are an exciting addition to routine angioplasty. These metallic tubular structures are inserted into the artery during angioplasty. These devices act as scaffolding to keep the artery widely dilated and tend to improve the result and reduce renarrowing.

In addition research to improve stents is uderway. Stents can now be coated with a variety of materials that:

* can prevent clotting (heparin)
* may reduce restenosis

Radiation:

Both beta and gamma forms of ionizing radiation are currently being studies as ways to slow the healing or restenosis (renarrowing) process. Early studies are promising.

Answer 3

the contrast dye is injected prior to the plasty, it is used to visualize the vessels and the amount of blockage. The balloon is inflated with plain old air.

Answer 4

You can avoid bypass or angioplast with Rudved ayurvedic capsules.

Answer 5

Oxygen maybe and eosin or some other normal staining dye?
