Which procedure is primarily focused on restoring blood flow in a blocked artery?

• A. Venography
• B. Stenting
• C. Embolization
• D. Angioplasty

Answer: (D)

The procedure primarily focused on restoring blood flow in a blocked artery is angioplasty. Angioplasty involves the insertion of a catheter with a balloon at its tip into the affected artery. Once positioned at the site of the blockage, the balloon is inflated to expand the artery, which helps to compress any plaque against the artery wall and restore blood flow.

This procedure is particularly effective in cases of arterial stenosis (narrowing of the artery due to plaque buildup) and is commonly used in heart disease treatment to open blocked coronary arteries. It can be performed alone or in conjunction with other interventions, such as stenting, where a small mesh tube is placed to keep the artery open after angioplasty.

While stenting does aid in maintaining the openness of an artery after balloon dilation, its primary function is supportive rather than directly restoring blood flow on its own. Other options, such as venography, focus on the evaluation of veins rather than treating blockages in arteries, and embolization is a procedure designed to intentionally block blood flow to a specific area, typically to treat tumors or abnormal vascular structures. Thus, angioplasty stands out as the key procedure aimed explicitly at reopening blocked arteries to restore normal blood flow.
