Blood coagulation is the process that causes blood to clot and helps prevent excessive blood loss when a vein or artery is pierced or broken.
|
|
Fibrin sealants are a type of surgical tissue adhesive derived from human and animal blood products. The ingredients in these sealants interact during application to form a stable clot composed of a blood protein called fibrin. Fibrin sealants are...
|
|
Fibrin split products (FSP) are fragments of protein released from a dissolving clot. The fibrin split products test is one of several tests done to evaluate a person with blood clotting problems (coagulation), particularly disseminated intravascu...
|
|
Coagulation disorders deal with disruption of the body's ability to control blood clotting. The most commonly known coagulation disorder is hemophilia , a condition in which patients bleed for long periods of time before clotting. There are other ...

Coagulation disorders (coagulopathies) are disruptions in the body's ability to control blood clotting, an essential function of the body designed to prevent blood loss. The most commonly known coagulation disorder is hemophilia , a condition in w...
|
|
Hemostasis has been described as "a process by which the body spontaneously stops bleeding and maintains blood in the fluid state within the vascular compartment." There are at least four major systems that are involved in this complex process: th...
|
|
When injury occurs to a blood vessel wall, thrombin (a coagulation enzyme) is formed in the first stage of a complicated series of steps called the coagulation cascade. In the second phase, fibrinogen, a coagulation protein made by the liver , is ...

Computed tomography (CT) scanning is a valuable diagnostic tool that provides physicians with views of internal body structures. During a CT scan, multiple x rays are passed through the body, producing cross-sectional images, or "slices, " on a ca...
|
 |
Computed tomography (CT), formerly referred to as computerized axial tomography (CAT), is a common diagnostic imaging procedure that uses x rays to generate images (slices) of the anatomy.
|
 |
Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross-sectional views of body organs and tissues.
|
