The most common artery for embolism is the carotid artery. The carotid artery is located in the neck and supplies blood to the head and neck. Embolism occurs when a foreign object or clot of material blocks the flow of blood to the brain, causing a stroke. Embolism can be caused by a variety of factors, including a build-up of plaque in the carotid artery, a clot that has broken off from the wall of another artery, or a piece of a foreign object that has been injected into the bloodstream.
When an embolism occurs, the symptoms can range from mild to severe. Depending on the size of the blockage, the patient may experience dizziness, headache, confusion, or even loss of consciousness. If left untreated, the blockage can cause permanent damage, such as a stroke or even death.
Treatment for an embolism can include medications to reduce inflammation and clotting, as well as surgery to remove the blockage. In addition, lifestyle changes such as quitting smoking and limiting alcohol consumption can help reduce the risk of embolism.
