What happens in the brain when a person has an embolism?
brain embolism: If a blood clot travels to the brain, this causes an ischemic stroke or TIA (transient ischemic attack). retinal embolism: Small clots that wouldn’t block a major artery can block the smaller blood vessels feeding the retina at the back of the eye. The result is usually sudden blindness in one eye.
How serious is a brain embolism?
Embolic stroke is a life-threatening condition. Every second counts. Blood flow to the brain must be restored as quickly as possible. Your doctor may do this with oral or intravenous clot-busting medications.
Where does cerebral embolism occur?
A cerebral embolism is a blood clot (thrombus) that starts from the heart or blood vessel where the clot originates and stops in an artery that leads to or rests within the brain.
How is brain embolism treated?
Treatment of cerebral embolism consists of two major strategies: (1) acute thrombolytic therapy to lyse the embolus and (2) prevention of recurrence of embolic events using long‐term prophylactic therapy and removal of the embolic source(s).
How do you recognize embolism?
Symptoms of fat embolism syndrome

- shortness of breath.
- mental confusion.
- lethargy.
- coma.
- pinpoint rash (called a petechial rash), often found on the chest, head, and neck area, which occurs due to bleeding under the skin.

What does a brain embolism feel like?
“Some patients describe it as being hit in the back of a head by a sledgehammer,” Bain says. Other symptoms include those that Mureddu experienced: nausea, vomiting, and sudden blurred or double vision, as well as a stiff neck, dizziness, sensitivity to light, and drooping eyelids.
How are clots removed from the brain?
Generally speaking, there are two surgical treatment options to remove the blood clot: burr hole drainage and craniotomy. During burr hole drainage, the neurosurgeon will create one or two small holes within the skull, followed by an incision in the dura if necessary, in order to drain the blood clot.
Who is at risk for fat embolism?
Fat emboli occur in all patients with long-bone fractures, but only few patients develop systemic dysfunction, particularly the triad of skin, brain, and lung dysfunction known as the fat embolism syndrome (FES). Here we review the FES literature under different subheadings. The incidence of FES varies from 1–29%.
