What is hematoma and contusion?

A bruise, also known as a contusion, typically appears on the skin after trauma such as a blow to the body. It occurs when the small veins and capillaries under the skin break. A hematoma is a collection (or pooling) of blood outside the blood vessel.

What causes contusion hematoma?

Most commonly, hematomas are caused by an injury to the wall of a blood vessel, prompting blood to seep out of the blood vessel into the surrounding tissues. A hematoma can result from an injury to any type of blood vessel (artery, vein, or small capillary).

How long does a hematoma lump last?

The swelling and pain of the hematoma will go away. This takes from 1 to 4 weeks, depending on the size of the hematoma. The skin over the hematoma may turn bluish then brown and yellow as the blood is dissolved and absorbed. Usually, this only takes a couple of weeks but can last months.

Contusions are a type of hematoma, which refers to any collection of blood outside of a blood vessel. While the term contusion might sound serious, it’s just a medical term for the common bruise.

What are the stages of a hematoma?

In general, five stages of hematoma evolution are recognized: hyperacute (<1day) intracellular oxyhemoglobin. isointense on T1 acute (1 to 3 days) intracellular deoxyhemoglobin. T2 signal intensity drops (T2 shortening) T1 remains intermediate-to-low early subacute (3 to 7 days) intracellular methemoglobin.

What are the risks of a hematoma?

A common complication of all hematomas is the risk of infection. Since there is no blood supply to a hematoma—it is a collection of old blood—there is a risk of bacteria colonizing the site. If the hematoma becomes large enough, it can compress tissues and prevent oxygen from reaching surrounding tissue.

How do you reduce a hematoma?

Alternate cold compression and heat will help the blood vessels to narrow and widen. This will allow the blood to dissolve soon in the body and reduce the size of hematoma. Elevate the part to prevent expansion of hematoma. Turmeric powder is of great importance in reducing the hematoma.
