Percutaneous transluminal angioplasty (PTA) is a minimally invasive procedure used to treat narrowed or blocked arteries caused by conditions like peripheral artery disease (PAD). During the procedure, a balloon catheter is inserted into the affected artery through a small incision and inflated to widen the artery, restoring blood flow.

PTA is commonly used for patients with claudication, non-healing wounds, or tissue ischemia due to arterial blockages. It offers a quicker recovery time and less risk than traditional surgery while effectively improving circulation.
