Interventional procedures are medical techniques used to diagnose or treat various health conditions through minimally invasive methods. These procedures often involve the use of imaging technology, such as X-rays or ultrasound, to guide instruments into the body. Common examples include angioplasty, where a balloon is used to open narrowed blood vessels, and biopsies, which involve taking tissue samples for analysis. These procedures are typically performed by specialists, such as interventional radiologists or cardiologists, and can often be done on an outpatient basis. They aim to reduce recovery time and minimize complications compared to traditional surgery, making them a preferred option for many patients.
