Diagnostic Evaluation Presentation Profile Adolescents with heavy menstrual bleeding should be carefully evaluated and the presentation profile is quite important when one is considering a platelet function disorder etiology. [omicsonline.org]

The most common factor deficiencies are Factor VIII (Hemophilia A) and Factor IX (Hemophilia B), which are indistinguishable based on clinical presentation alone. [iupui.edu]

Thus, the clinical presentation (mild or moderate bleeding) and laboratory profile for these disorders are similar. [clinchem.aaccjnls.org]

The current pregnancy had a breech presentation, for which the patient was scheduled for a cesarean delivery. [anesthesiology.pubs.asahq.org]

Common symptoms are present across all variances. Severe bleeding disorders tend to result in more severe symptoms. [babymed.com]

If the patient has a strong personal or family history of mucocutaneous bleeding, VWD testing should be pursued early in the workup. [clinchem.aaccjnls.org]

A peripheral smear serves several purposes in a bleeding workup. [aafp.org]

A more in-depth hematologic workup is required to confirm the diagnosis of vWD. Hemophilia A (factor VIII deficiency) does not affect the platelet count or the PT. [ahcmedia.com]

Treatments The attending physician will prescribe treatment based on the type of bleeding disorder. [babymed.com]

Life Expectancy Prognosis for patients with bleeding disorders is disease or disorder specific. If the bleeding disorder is caused by an underlying disease, the prognosis will depend on treatment of the disease. [babymed.com]

Prognosis Good Poor A variety of drugs have been reported to cause thrombocytopenia either by drug-induced platelet destruction or bone marrow suppression. Heparin merits special emphasis because it is so commonly used. [hawaii.edu]

Prognosis Poor prognosis is associated with persistent severe thrombocytopenia (less than 10,000/uL) that is refractory to platelet transfusions; prolonged PT or PTT values that show modest reductions toward normal with plasma or factor concentrates; [clinicaladvisor.com]

Results: Heavy menstrual bleeding affects the quality of life of many adolescents, and PFDs appearing to be an important underlying etiology of this disorder. [omicsonline.org]

[…] factor VIII has shorter half life and its plasma levels are lower Note: type O patients have lower levels of vWF (75 IU/dl), type AB patients have highest levels (123 IU/dl) ( Blood 1987;69:1691 ); levels increase with age and with acute phase reactions Etiology [pathologyoutlines.com]

If initial testing does not reveal an etiology in a patient with a high suspicion for a bleeding disorder, the patient should be referred to a hematologist for additional evaluation. [aafp.org]

In addition, the etiology of the thrombocytopenia is often unclear. [anesthesiology.pubs.asahq.org]

Epidemiology Most bleeding is a result of a structural lesion. If the ICU patient is bleeding from a single site, the likelihood of bleeding from a structural lesion, rather than a coagulopathy, is high. [clinicaladvisor.com]
