Have you ever known someone who had to go in for a test after having chest pain, horrible angiography video leg pain coupled with a lack of pulses in the feet, or mini-stroke type angiography video Or perhaps someone you know was having trouble breathing and was suspected to have a lung clot? Any of these scenarios could be the reason for having angiography video done. Angiography is the test where dyes that can be seen by x-rays are injected into blood vessels either arteries or veins and examined using x-rays.

The resulting pictures are called angiograms. Angiograms are used to diagnose narrowing or blockages in vessels angiography video in the angiography video, from head to toe, including:. In addition to finding narrowing and blockages, angiography can also be used to find places where the arteries or veins are bulging or ballooning.

These spots are called aneurysms and if not treated, can cause death when they rupture. In order to do an angiogram, the patient is taken into a special procedure room. Oftentimes these rooms will have a setup similar to this one:. In the angiography video, you can see the bed where the patient will be placed and the c-arm that produces the x-rays that then are digitally transmitted to the set of screens on the other side of the angiography video bed.

At some point prior to procedure, the patient's groin or area above the elbow is clipped angiography video shaved and then cleaned with a surgical prep solution. Sterile drapes are then placed to help ensure that bacteria are not introduced directly into the patient's blood stream. Oftentimes, the patient is given fluids and some medication through an IV to help him or her relax during the procedure.

Monitors for blood pressure, the heart's electrical activity, and blood oxygen levels are also placed so that medical personnel in the room can keep an eye on the patient's condition. A thin tube called angiography video sheath is then placed in a major blood vessel aka the access site to allow the doctor to place different catheters into the vessels of interest and inject dye. As the dye is injected, the angiography video may get a warm flushed feeling in the body part being examined.

In this picture belowyou can see the catheter has been threaded up through the femoral artery which goes to the lower part of the aorta, which is the major artery coming out of the heart. The physician can then inject dye and see the outline of the angiography video under x-ray to check for narrowing or aneurysms. In this image belowdye has been injected into the arteries feeding the heart muscle.

The arrows indicate significant blockages that will need to be fixed using angioplasty or a coronary artery bypass graft. The more common complications from angiography are related to the dye used and the access site itself.

The medical personnel will watch for signs of bleeding around the site until you go home. Swelling, bleeding, or a collection of blood under the skin called a hematoma may occur at this site if the major vessel angiography video not adequately sealed over. Minor bruising at the access site is not angiography video and will go away with time. Angiography video will be given precautions to follow for one to two weeks after the procedure to avoid the access site opening back up.

If a patient has any kind of history of kidney disease, additional precautions must be taken. Extra fluids and medications may be given to help clear the dye out of the body without causing damage to the kidneys.

If the patient has a history of heart failure or kidney damage, caution may need to be used in terms of how much fluid is given since fluid overload could occur, leading to problems with breathing. Allergic reactions to the dye may occur. If the patient is allergic to shellfish or iodine, he or she is often pre-medicated with steroids and antihistamines to help avoid reactions to the dye used during the procedure.

Let's review. Angiography is a fairly common procedure used to directly examine the blood vessels for blockages or narrowing. The procedure is done in a sterile angiography video to avoid introducing bacteria directly into the patient's blood stream. A dye that can be seen under x-ray is injected into the vessels, and the resulting pictures called angiograms are examined in real time by the physician performing the procedure.

Potential complications include bleeding at the access site, hematoma formation, allergic reaction to dye, and potential kidney damage in patients with compromised kidney function.

To complete a coronary angiogram, a catheter is inserted in an artery in your groin or arm and threaded through your blood vessels to your heart.

Your doctor angiography video the angiogram to check for blocked or narrowed blood vessels in your heart. A small incision is made at the entry site, and a short plastic tube sheath is inserted into your artery. The catheter is inserted through the sheath into your blood vessel and carefully threaded to your heart or coronary arteries.

Threading the catheter shouldn't cause pain, and you shouldn't feel it moving through your body. Tell your health care team if you have any discomfort. Dye contrast material is injected through the catheter. When this happens, you may have a brief sensation of flushing or warmth. But again, tell your health care team if you feel pain or discomfort.

The dye is easy to see on X-ray images. As it moves through your blood vessels, your doctor can observe its flow and identify any blockages or constricted areas. Depending on what your doctor discovers during your angiogram, you may have additional catheter procedures at the same time, such as a balloon angioplasty or a stent placement to open up a narrowed artery.

Having an angiogram takes about one hour, although it may be longer, especially if combined with other cardiac catheterization procedures. Preparation and post-procedure care can angiography video more time. When the angiogram is over, the catheter is removed from your arm or groin and the incision is closed with manual pressure, a clamp or a small plug.

You'll be taken to a recovery area for observation and monitoring. When your condition is stable, you return to your own room, where you're monitored regularly.

You'll need to lie flat for several hours to avoid bleeding if the catheter was inserted in the groin. During this time, pressure may be applied to the incision to prevent bleeding and promote healing. You may be able to go home the same day, or you may have to remain in the hospital overnight.
