| Definition: |
Splinter hemorrhages are small areas of bleeding or hemorrhage under fingernails or toenails. They take the shape of straight lines and may be caused by microembolic damage to the vessels.
|
| Alternative Names: |
Fingernail hemorrhage
|
| Considerations: |
Splinter hemorrhages appear as narrow red to reddish brown hemorrhages beneath the nails. They run in the direction of nail growth and are named splinter hemorrhage because they have the appearance of a splinter beneath the fingernail. The hemorrhages may be caused by microscopic clots that damage the small capillaries under the nails.
Splinter hemorrhages are associated with endocarditis and may represent vessel damage from inflammation of the blood vessels (vasculitis) or microscopic clots that damage the small capillaries (microemboli). |
| Common Causes: |
- Trauma to the nail (most common cause)
- Subacute or acute bacterial endocarditis
|
| Home Care: |
| There is no particular care for splinter hemorrhages. Strictly adhere to your health care provider's instructions for the treatment of endocarditis. |
| Call your health care provider if: |
- You notice splinter hemorrhages in the absence of recent trauma to the nail
Note: Splinter hemorrhages generally are a late-appearing symptom in endocarditis. It is probable that other symptoms causing a visit to the health care provider will have appeared before the appearance of splinter hemorrhages. |
| What to expect at your health care provider's office: |
