No, angiography itself is primarily a diagnostic procedure and does not directly clear blockages. However, it can be immediately followed by angioplasty, a procedure that can clear blockages.
Here's a breakdown:
-
Angiography (The Diagnostic Tool): This procedure uses X-rays and a contrast dye to visualize blood vessels. It helps doctors identify the location and severity of blockages in arteries. The primary purpose is diagnosis, not treatment.
-
Angioplasty (The Treatment): Often performed immediately following an angiogram, angioplasty is a procedure used to open blocked arteries. During angioplasty, a catheter with a balloon on the tip is inserted into the artery. The balloon is inflated at the site of the blockage, compressing the plaque and widening the artery. A stent (a small mesh tube) is usually placed to help keep the artery open.
In summary:
| Procedure | Purpose | Clears Blockage? |
|---|---|---|
| Angiography | Diagnose Blockages | No |
| Angioplasty | Treat/Clear Blockages | Yes |
Therefore, while angiography itself cannot clear a blockage, it provides the information necessary to determine if an angioplasty (which can clear a blockage) is needed and can be performed immediately afterwards. In cases of severe blockages, a bypass operation might be a more appropriate solution.
