Is the formation of atherosclerotic plaques in the right carotid artery serious?

The severity of atherosclerotic plaques in the right carotid artery depends on the size of the plaque and whether clinical symptoms are present. If the plaque is relatively small and does not cause obvious clinical symptoms, it is generally not considered severe. However, if the plaque is large and causes significant narrowing or blockage of the blood vessel, it is usually considered serious. It is recommended to seek timely medical evaluation to clarify the condition and, if necessary, receive appropriate treatment.

1. Not Severe

When the plaque is small in size and limited in number, and does not significantly obstruct the arterial lumen or cause blood stasis, the condition is typically not severe. Patients usually do not experience ischemic or hypoxic brain symptoms such as headache, dizziness, or visual darkening.

2. Severe

If the plaque is large enough to cause significant vascular obstruction, the condition is generally considered serious. This can lead to insufficient blood supply to the brain, causing symptoms such as headache and dizziness. In severe cases, it may result in cerebral infarction, potentially leading to coma, shock, or even death.

Treatment usually requires medications prescribed by a physician, such as thrombolytic agents including urokinase for injection, recombinant streptokinase for injection, and alteplase for injection.
