What hemophilia means?
Hemophilia is usually an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery. Blood contains many proteins called clotting factors that can help to stop bleeding.
What is hemophilia classification?
Hemophilia is classified according to clinical severity as mild, moderate, or severe (see Table 1, below). Patients with severe disease usually have less than 1% factor VIII (FVIII) activity and experience spontaneous hemarthrosis and soft-tissue bleeding in the absence of apparent precipitating trauma.
What is clinical presentation of hemophilia?
Signs and symptoms of spontaneous bleeding include: Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work. Many large or deep bruises. Unusual bleeding after vaccinations. Pain, swelling or tightness in your joints.

In factor VIII deficiency (hemophilia A), the body doesn’t make enough factor VIII (factor 8), one of the substances the body needs to form a clot.
Why is bleeding time normal in hemophilia?
11, 12 The bleeding time is said to be normal in hemophilia because platelet adhesion and aggregation in response to ADP are normal, and because the mechanism that is initiated by tissue factor in the absence of factor VIII coagulant activity can apparently generate enough thrombin to stop bleeding from the small …
