What is a hematoma?
A hematoma is the result of a traumatic injury to your skin or the tissues underneath your skin.
When blood vessels under your skin are damaged and leak, the blood pools and results in abruise。血肿形式是你的blood clots, resulting inswellingand pain.
Hematomas can occur anywhere in your body, including your leg.
Although hematomas can show up elsewhere, if they appear on your leg, it’s usually due to injury such as a blow to your leg from a fall or an encounter with a blunt object.
在你有一定的腿部手术后也可以形成血肿。
如果你服用血液的药物，你的血肿可能会增加，例如：
- aspirin
- apixaban(Eliquis)
- warfarin(Coumadin)
- 氯吡格雷(Plavix)
- prasugrel (Effient)
- rivaroxaban（Xarelto）
如果您患有病毒感染，例如：
- hepatitis C
- HIV
- parvovirus
可以提高血肿风险的其他条件包括：
- 血小板减少症, or low blood platelet count
- 再生障碍性贫血, when your bone marrow stops making blood cells
- 酒精使用障碍
- vitamin D deficiency
The primary symptoms of a leg hematoma are:
- discoloration from the blood under your skin
- swelling
- 疼痛
Usually the extent of the discoloration and swelling reflect the severity of the injury. Fracturing your thigh bone (femur) is commonly associated with a significant amount of bleeding and will often result in a large hematoma.
Hematomas usually clear on their own, slowly getting smaller over time as the accumulated blood is absorbed. It might take months for a large hematoma to be fully absorbed.
Commonly, a leg hematoma is treated with:
- cold compress要么ice pack在伤害后48小时施用20至30分钟以减少肿胀后的48小时
- 休息
- elevating your foot高于你的心
- light compression with包裹的绷带
- 疼痛medication such as对乙酰氨基酚(Tylenol)
- 在受伤后48小时加热10分钟，在伤害增加血液流动后48小时
If you’re treating a hematoma at home, do not take aspirin oribuprofen(Advil, Motrin). These over-the-counter drugs aren’t recommended because they can slow blood clotting.
Surgery
If you have a hematoma over your shinbone, your doctor may recommend surgery. If you have a large hematoma that doesn’t go away for several days following your injury, your doctor might suggest that it be drained.
If you bruise your leg and the bruise becomes swollen and painful, you could have a hematoma. It could indicate an injury that is — or complications that are — more severe than you think, especially if the bruise doesn’t improve over a week or two. See your doctor so they can examine your leg and make a treatment recommendation. If you think you’ve折断你的腿, be sure to get emergency medical attention.
