Question

Quizplus · Accepted Answer

Balloon angioplasty is a procedure in which a balloon catheter is inserted into a blocked or narrowed blood vessel and inflated to widen the vessel and improve blood flow. This can be done in combination with stenting, where a small wire mesh tube is placed in the vessel to keep it open. Angiography is a diagnostic procedure that uses contrast dye and X-rays to visualize blood vessels, while embolization and TIPS are treatments for specific conditions (blocking blood flow to a tumor or rerouting blood flow in the liver, respectively), not for opening narrowed vessels.
