Septic embolism is a type of infection inside a blood vessel. This term specifically refers to an infection that started in one part of the body and traveled through blood vessels to reach another part of the body, possibly blocking one or more blood vessels.

Typically, septic embolism is a bacterial infection that originates in the heart valves. This may be associated withinfective endocarditis, an infection of the heart. An infection in the heart can result in a small blood clot, which may travel to other parts of the body.

When a bacterial infection or an infected blood clot travels from the heart to the brain, it can block a blood vessel in the brain, causing astroke, transient ischemic attack (TIA), cerebral hemorrhage, meningitis, brain abscess, or a mycotic aneurysm.

Strokes resulting from a septic embolism are classified as septic strokes, which means infected strokes.

There are a number of conditions and infections that can cause septic embolism, including:

There are also some lifestyle factors known to contribute to the risk of septic embolism. Intravenous (IV) drug use, in particular, increases the risk of a harmful infection that can cause endocarditis or septic embolism. Typically, when IV drug use is the cause of septic embolism, it begins when bacteria on the skin enter the body and cause an infection. The infection may develop slowly or could progress rapidly.

Infective endocarditis may cause destruction of the valves located in the heart, potentially resulting in complications such as congestive heart failure and recurrent septic embolism.

There are a number of symptoms of septic embolism, but they tend to be non-specific symptoms along the lines of “feeling lousy.” This is one of the reasons it takes a while to reach a diagnosis. If you persistently experience the symptoms of septic embolism, your healthcare provider will do a detailed medical checkup to search for the cause of your symptoms.

Neurological symptoms include:

Non-neurological symptoms include:

Septic embolism can be difficult to diagnose. Most people with septic embolism have a positive blood culture, meaning bacteria are detected in the blood. A positive blood culture helps direct your treatment if you have septic embolism,because your healthcare provider can identify which bacteria are present, and thus which antibiotic is expected to be most effective. A positive blood culture does not define the location or the cause of the infection.

Other diagnostic tests are used to further evaluate septic embolism to locate the area of infection and determine the extent of the infection.

Diagnostic TestsTests for septic embolism include:Complete blood count (CBC)Angiogram (an image of the blood vessels)Magnetic resonance imaging (MRI)Transesophageal echocardiogramElectrocardiogramChest X-raySpinal tapBlood cultures
