Some people at high risk may need to take blood thinners to prevent blood clots.But new Michigan Medicine research, published in JAMA Network Open, finds that some patients with PE, a blood clot in one or more pulmonary arteries, may be hospitalized unnecessarily due to computed tomography (CT) imaging results rather than clinical risk factors.Īpproximately 40% of the patients in the study had low-risk pulmonary embolism, as defined by the Pulmonary Embolism Severity Index, or PESI score. Getting up and moving around every few hours when you have to sit for long periods of time, for example if you are on a long flight or car trip.Moving around as soon as possible after having been confined to your bed, such as after surgery, illness, or injury.You may be able to help prevent blood clots by: Surgery and other procedures to remove the blood clots.They are usually used where the blood clots are severe.

Normally the venous sinuses drain blood from your brain. Cerebral venous sinus thrombosis (CVST) is a rare blood clot in the venous sinuses in your brain.
