Fibrinogen and catheter-directed thrombolysis.

Fibrinogen is a complex glycoprotein that is known to play a significant role in the process of thrombus formation and evolution, and has been linked to the pathophysiology of atherosclerosis. Given the importance of fibrinogen in these processes, it has been evaluated as a biomarker for atherosclerotic disease and as a marker during treatment for venous and arterial thrombosis. Here we describe the expansive role that fibrinogen plays in human physiology.
