* Arterial blockage: This is the most common and straightforward way to spell it.
* Arterial occlusion: This is a more medical term that emphasizes the complete closure of an artery.
* Arterial stenosis: This term refers to a narrowing of an artery, which can lead to blockage.
The best way to spell it depends on the specific context. For example, if you are writing a medical report, you would likely use "arterial occlusion" or "arterial stenosis." However, if you are writing a general article about heart health, "arterial blockage" would be more appropriate.
