Thrombocytopathy is an abnormality of platelets. It may be congenital or acquired. It may cause a thrombotic or a bleeding tendency or may be part of a wider disorder such as myelodysplasia. Under normal circumstances, when the endothelial cells lining blood vessels are breached, platelets interact with von Willebrand factor (vWF) via the membrane glycoprotein 1b complex to help seal the breach. Glycoprotein IIb/Ia complex attracts other platelets, which combine to form aggregates.[1] The platelets contain granules which break down to release fibrinogen, vWF, platelet-derived growth factor adenosine 5'-diphosphate (ADP), calcium and 5-hydroxytryptamine (5-HT) - serotonin. All this helps to promote the formation of a haemostatic plug (primary haemostasis).
