What is balloon dilatation?

Balloon dilation is an interventional procedure commonly used to treat cardiovascular diseases.

Balloon dilation is inserted into the body through a catheter to find the site of stenosis or obstruction in the cardiovascular system. Then, fluid is injected into the catheter under pressure to inflate the balloon at the tip of the catheter to open the stenosis or obstruction, thereby restoring blood flow.

It is important to note that balloon dilation is a non-radical treatment that only relieves symptoms. There is a possibility of restenosis after surgery. Therefore, patients need to maintain good living habits and follow doctor's advice after surgery to reduce the risk of restenosis.
