Which of the following is a procedure that can correct a blockage in blood vessels?

Revascularization is a procedure specifically designed to restore blood flow in blocked or narrowed blood vessels. It encompasses techniques such as angioplasty, where a small balloon is used to widen the affected area, and the placement of stents to keep the vessel open. This procedure is critical in managing conditions like coronary artery disease, where blood supply to the heart is compromised.

While thrombectomy, another option, involves removing a blood clot to restore flow, revascularization encompasses a broader range of techniques suitable for various types of blockages, not just those caused by clots. Dialysis, on the other hand, is a treatment for kidney failure that filters waste from the blood, and endoscopy is a minimally invasive procedure used to examine the gastrointestinal tract, neither of which addresses blood vessel blockages.
