2Definition
bleeding disorders due to inherited deficiencies of coagulation factors
![Page 4: Sinan abdulhammed hemophilia](https://reader030.fdocuments.net/reader030/viewer/2022032618/55b95c77bb61eb20448b47c9/html5/thumbnails/4.jpg)
3Causes
Inherited as a sex linked recessive trait with bleeding manifestations only in males.female carriers transmit the abnormal gene. genes which control factor VIII and IX production are located on the x chromosome; if the gene is defective synthesis of these proteins is defective

After injury, the initial hemostatic event is formation of the platelet plug, together with the generation of the fibrin clot that prevents further hemorrhage. In hemophilia A or B, clot formation is delayed and is not robust.

7Clinical Features
Bleeding in : ●Joints (Hem arthrosis) ● muscle or soft tissue ●Abdomen ●GI tract ●Intracranial*Serious* ●Around vital structures in the neck

8Severity
severity is dependent on blood levels of functioning factor VIII or IX
% normal factor level
Causes of bleeding
Severe < 1% bleeding after trivial injury or spontaneous
Moderate 1 - 5% bleeding after minor injury; occasional spontaneous bleeds
Mild 6 - 30 % following major trauma, surgical or dental procedures

9Diagnosis
● family history.
●measuring the level of factor activity in
the blood.
●prolongation of APTT.
●All other screening tests of with in normal
limit.
