Balloon angioplasty: A minimally invasive procedure for treating blocked arteries

Zhen Zhao

Balloon angioplasty, also known as percutaneous transluminal angioplasty (PTA), is a medical procedure used to treat blocked or narrowed blood vessels. During this procedure, a small balloon catheter is inserted into the affected artery and guided to the site of blockage or narrowing. Once the balloon is in place, it inflates and pushes plaque and blockages against the artery wall, improving blood flow.
