Thrombosis na hemostasis bụ ọrụ physiological dị mkpa nke ahụ mmadụ, gụnyere arịa ọbara, platelet, ihe na-akpata coagulation, protein anticoagulant, na sistem fibrinolytic.Ha bụ usoro usoro ziri ezi nke na-eme ka oruru ọbara na-eru n'ahụ mmadụ anya.Na-aga n'ihu na-ekesa mmiri na-aga n'ihu, ọ bụghị na-esi na arịa ọbara pụta (hemorrhage) ma ọ bụ coagulation na arịa ọbara (thrombosis).

A na-ekewa usoro nke thrombosis na hemostasis n'ime usoro atọ:

Hemostasis nke mbụ na-etinye aka na mgbidi arịa, sel endothelial, na platelet.Mgbe arịa merụrụ ahụ, platelet na-agbakọta ngwa ngwa iji kwụsị ọbara ọgbụgba.

Hemostasis nke abụọ, nke a makwaara dị ka hemostasis plasma, na-eme ka sistemu coagulation rụọ ọrụ iji gbanwee fibrinogen ka ọ bụrụ fibrin na-ejikọtaghị ọnụ, nke na-etolite nnukwu mkpụkọ.

Fibrinolysis, nke na-agbaji fibrin mkpụkọ ma na-eweghachi usoro ọbara nkịtị.

A na-ahazi usoro ọ bụla nke ọma iji kwado ọnọdụ nguzozi.Mmebi na njikọ ọ bụla ga-eduga na ọrịa ndị metụtara ya.

Nsogbu ọbara ọgbụgba bụ okwu n'ozuzu maka ọrịa nke usoro hemostasis na-adịghị mma kpatara.Enwere ike kewaa nsogbu ọbara ọgbụgba ụzọ abụọ: ihe nketa na nke enwetara, na ngosipụta ụlọ ọgwụ na-abụkarị ọbara ọgbụgba n'akụkụ dị iche iche.Ọrịa ọgbụgba ọbara na-ahụ maka afọ, hemophilia A na-ahụkarị (erughị eru coagulation factor VIII), hemophilia B (erughị nke coagulation factor IX) na coagulation abnormalities nke na-akpata ụkọ fibrinogen;nsogbu ọbara ọgbụgba enwetara, nke a na-ahụkarị Enwere vitamin K na-adabere na ụkọ coagulation factor, ihe na-adịghị mma nke ọrịa imeju kpatara, wdg.

A na-ekekarị ọrịa thromboembolism n'ime akwara akwara na thromboembolism venous (venousthromboembolism, VTE).Ọkpụkpụ akwara na-adịkarị na akwara akwara, akwara ụbụrụ, akwara mesenteric, na akwara ụkwụ, wdg.
