Stroke treatments

Stroke treatments in St. Louis

Description

Any treatment of a patient who has experienced a stroke or has experienced signs that a stroke might be likely. A stroke happens when blood flow to a part of the brain is interrupted as a result of a ruptured or blocked blood vessel. Brain cells that do not receive a constant supply of oxygenated blood may die, causing permanent damage to the brain. The first step in assessing a stroke patient is to determine what type of stroke the patient has had so the correct treatment can begin. A computed tomography (CT) scan or MRI of the head is typically the first test performed. CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images or picture of the inside of the body. A CT of the head is used to detect a stroke from a blood clot or bleeding within the brain. To improve the detection and characterization of stroke, CT angiography (CTA) may be performed. MRI of the head may also be performed and uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. MR is also used to image the cerebral vessels using MR angiography (MRA). Ultrasound technology may also be used. Ultrasound imaging involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body. A Doppler ultrasound may be used to check for narrowing and blockages in the carotid arteries which are located on each side of the neck and carry blood from the heart to the brain.
