Doctors help your blood flow.
They use a tiny balloon. The balloon goes inside a tube. It grows big to make space. This helps your body stay well.
Can you imagine a tiny balloon? It helps you feel better.
Sometimes, the tubes in your body get narrow.
This can make it hard for blood to move. Doctors can help fix this. They use a tiny balloon on a thin tube.
The doctor puts the tube inside the narrow part. Then, they blow up the tiny balloon. The balloon pushes the walls open to make more space. This helps the blood flow well again. Sometimes, they leave a small mesh tube to keep it open. This helps your body stay healthy.
Sometimes, the tubes in your body get narrow. These tubes are called arteries or veins. They carry blood to different parts of you. A buildup of plaque can block them. This can make it hard for blood to move.
Doctors use a way to fix this called angioplasty. They use a thin tube called a catheter. A tiny balloon is attached to the end.
The doctor puts the tube into a blood vessel. They use X-rays to see where it goes. This is called fluoroscopy. Once it reaches the narrow spot, the doctor blows up the balloon. The balloon pushes the walls open. This makes more room for blood to flow.
Sometimes, doctors use a stent. A stent is a small mesh tube. It stays in the vessel to keep it open. The doctor might also use a tool called an atherectomy. This tool uses a spinning part to clear hard plaque. Most people go home the day after the procedure. They may walk just a few hours after it is done.
Your body uses tubes called arteries and veins to move blood. Sometimes, these tubes get narrow or blocked. This often happens because of a buildup called plaque. This plaque is made of cholesterol. When it builds up, it makes it hard for blood to flow. This can cause chest pain, which is called angina.
Doctors use a special way to fix this. It is called angioplasty. This is a way to widen the tubes without a large surgery. It is a minimally invasive way to help blood move again.
To start, a doctor finds an access vessel. This is usually a large tube like the femoral artery in the leg. They use a technique called the Seldinger technique to enter the vessel. A thin wire is passed through the narrow spot. Then, a catheter with a tiny balloon is moved over the wire.
Doctors use X-rays to see the work in real time. This tool is called fluoroscopy. They use a special dye to make the vessels show up on the screen. Once the balloon is in place, they inflate it. The balloon can reach 75 to 500 times normal blood pressure. This forces the vessel walls to expand.
Sometimes, the plaque is very hard. This is called calcified plaque. If a balloon cannot open the vessel, doctors use other tools. One tool is called an atherectomy. This uses a spinning part to clear the hard buildup. Some use a diamond-encrusted burr for rotational atherectomy. Other tools use a laser to break up the plaque. These tools help prepare the vessel for the balloon. They make the path easier for the doctor to work on.
Doctors may also use a stent during the process. A stent is a small mesh tube. It stays inside the vessel to keep it open. This can help prevent the tube from narrowing again. Angioplasty can be used in many places. It can treat the heart, the legs, or even the kidneys. It can also be used for the carotid arteries in the neck. For some patients, doctors might choose bypass surgery instead. This is a different kind of surgery to move blood around the blockage.
After the procedure, most people stay in the hospital overnight. They might even go home the very next day. Doctors watch the patient's heart rate and blood pressure. They also check the spot where the tube entered the body. Patients can often walk within two to six hours. They may take medicine to help their arteries stay relaxed. This helps prevent spasms in the blood vessels. Most people find that their quality of life improves after the blood flows better.
Angioplasty is a minimally invasive endovascular procedure used to widen blood vessels. These vessels may be narrowed or obstructed by a buildup of material. This condition is often caused by atherosclerosis, which is the buildup of cholesterol-laden plaques.
Doctors use this technique to restore proper blood flow to vital organs. It is also known as balloon angioplasty or percutaneous transluminal angioplasty. This procedure is a common way to treat various vascular diseases without large surgical incisions.
The process begins by gaining access to the vascular system. Doctors typically enter through an access vessel like the femoral or radial artery. They use a method called the Seldinger technique to insert an introducer sheath.
A guide-wire is then passed through the narrowed section, known as a stenosis. A balloon catheter is moved over this wire into the desired position. To see the progress, doctors use fluoroscopy, which is real-time X-ray guidance. They also use a radiopaque contrast dye to make the vessels visible on screens.
Once positioned, the balloon is inflated using a mixture of water and contrast dye. This inflation can reach 75 to 500 times normal blood pressure. This pressure forces the vessel and its muscular wall to expand.
In many cases, doctors will also insert a stent during the procedure. A stent is a small mesh tube that helps keep the vessel open. After the stent is placed, the balloon is deflated and withdrawn. There are different types of interventions depending on the patient's needs. For example, percutaneous coronary intervention (PCI) specifically refers to angioplasty performed on the heart's arteries. Some doctors may also use drug-coated balloons to help prevent the vessel from narrowing again.
Angioplasty can be used in many different parts of the body. Coronary angioplasty treats the arteries of the heart to relieve symptoms like angina. Angina is chest pain caused by reduced blood flow. Peripheral angioplasty treats vessels outside the heart, such as those in the abdomen or legs. This can help patients with claudication, which is leg pain during movement. Renal artery angioplasty is used to treat narrowings in the kidney's arteries. Carotid angioplasty can treat the arteries in the neck to reduce stroke risk. Finally, venous angioplasty can treat narrowed veins, such as those used for dialysis.
Sometimes, the plaque in the vessel is very hard and calcified. In these difficult cases, doctors use an adjunctive therapy called atherectomy. This helps prepare the lesion so the balloon can work better. Rotational atherectomy uses a diamond-encrusted burr that spins at high speeds to grind the plaque. Orbital atherectomy uses a diamond-coated crown that orbits within the vessel. Another option is excimer laser coronary angioplasty, which uses ultraviolet laser energy to ablate the tissue. These tools help modify the plaque to allow for better expansion.
While angioplasty is lower-risk than major surgery, it does have specific risks. One risk is embolization, where debris is launched into the bloodstream. There is also a risk of bleeding from over-inflation or from the access site. Patients may develop a hematoma, which is a collection of blood under the skin. In carotid angioplasty, a serious complication called cerebral hyperperfusion syndrome can lead to a stroke. Additionally, angioplasty may be less durable than bypass surgery, as the vessel might experience restenosis, or re-narrowing.
Because of these factors, doctors must choose the right approach for each patient. For example, in cases of severe leg ischemia, bypass surgery might be preferred for long-term results. Guidelines suggest balloon angioplasty for patients with a life expectancy of two years or less. In the heart, doctors may avoid angioplasty if the narrowing is less than 70 percent. This is because the stenosis is not considered hemodynamically significant at that level. Choosing the correct access point is also vital, as the radial artery often has lower bleeding risks than the femoral artery.
