Yes, a 100% blocked artery, also known as a chronic total occlusion (CTO), can be unblocked using various procedures.
Understanding Chronic Total Occlusions (CTOs)
Chronic Total Occlusions (CTOs) are arteries completely blocked by plaque, often for months or even years. These blockages significantly restrict blood flow, leading to symptoms like chest pain (angina), shortness of breath, and fatigue. The good news is that treatment options exist to restore blood flow to the heart.
Treatment Options for 100% Blocked Arteries
According to current medical practices, there are primarily two approaches to treat a completely blocked artery:
-
Bypass Surgery: This involves surgically creating a new pathway for blood to flow around the blocked artery. A healthy blood vessel from another part of the body (e.g., leg, arm) is used to reroute blood flow, ensuring the heart muscle receives adequate oxygen and nutrients.
-
Non-Invasive Procedure (Cath Lab): This approach involves using techniques within a cardiac catheterization laboratory (cath lab) to open the blocked artery. According to the reference, this technique can be used to treat chronic total occlusions. This typically involves:
-
Angioplasty: A thin, flexible tube (catheter) is inserted into a blood vessel, usually in the arm or leg, and guided to the blocked artery.
-
Balloon Angioplasty: A small balloon at the tip of the catheter is inflated at the site of the blockage to compress the plaque against the artery walls, widening the artery.
-
Stenting: A small wire mesh tube (stent) is often placed in the artery after balloon angioplasty to help keep it open and prevent it from narrowing again. Specialized techniques and equipment are often required to cross the complete occlusion, but success rates have improved significantly over the years.

Considerations for Treatment
The best approach for unblocking a 100% blocked artery depends on several factors, including:
- The location and extent of the blockage.
- The patient's overall health.
- The presence of other medical conditions.
- The expertise and resources available at the medical center.
A cardiologist will evaluate these factors to determine the most appropriate treatment strategy.
