What nonsurgical technique is used to treat diseased arteries?

The correct answer is angioplasty, which is a nonsurgical technique used to treat diseased arteries. Angioplasty involves the use of a balloon catheter that is inserted into the narrowed or blocked artery. Once in place, the balloon is inflated, which helps to widen the artery and restore proper blood flow. This procedure can be performed without the need for extensive surgery and is often done on an outpatient basis, making it less invasive than other options.

Atherectomy, while also a nonsurgical technique, specifically involves the removal of plaque from the arteries and is not as commonly referred to as a first-line treatment compared to angioplasty. Bypass surgery is a surgical procedure that creates a new pathway for blood flow around a blocked artery and involves more invasive techniques. Stenting often accompanies angioplasty, where a small mesh tube is placed in the artery to keep it open after the balloon is deflated. Thus, while other techniques have their specific applications, angioplasty stands out as a primary nonsurgical intervention for treating arterial disease.
