Why Do Haematomas Occur?

What are the causes of hematoma? The most common cause of a hematoma is injury or trauma to blood vessels. This can happen as a result of any damage to blood vessels that can disrupt the integrity of the blood vessel wall. Even minimal damage to a small blood vessel can result in a hematoma.

What causes a bruising to occur?

Most bruises form when small blood vessels (capillaries) near the skin's surface are broken by the impact of a blow or injury — often on the arms or legs. When this happens, blood leaks out of the vessels and initially appears as a black-and-blue mark. Eventually your body reabsorbs the blood, and the mark disappears.

What does hematoma turn into and how does it happen?

When a blood vessel is damaged, blood leaks into the surrounding tissue; this blood tends to coagulate or clot. The greater the amount of bleeding that occurs, the larger the amount of clot (hematoma) formation.
