Subdural haematoma
Surgery is recommended for mostsubdural haematomas. Very small subdural haematomas may be carefully monitored first to see ifthey heal without having an operation.
If surgery is recommended, it will be carried out by aneurosurgeon (an expert in surgery of the brain and nervous system).
There are two widely used surgical techniques to treat subdural haematomas:
These techniques are discussed in more detail below.
A craniotomy is the main treatment for subdural haematomas that develop soon after a Head injury, severe (acute subdural haematomas).
During the procedure, the surgeon creates a temporary flap in the skull. Thehaematoma is gently removed using suction and irrigation, where it is washed away with fluid. After the procedure, the section of skull is put back in place and secured using metal plates or screws.
Thisis usually performed under a general anaesthetic , which means you'll be asleep while it's carried out.
Burr hole surgery is the main treatment forsubdural haematomas that develop a few days or weeks after a minor head injury (chronic subdural haematomas).
During the procedure, one or more small holes are drilled in the skull and a flexible rubber tube is inserted to drain the haematoma. Sometimes the tube may be left in place for a few days afterwards todrain away any blood and reduce the chances of the haematoma coming back.
Burr hole surgery is often carried out under general anaesthetic, but is sometimes doneunder local anaesthetic . Thismeans you remain awake during the procedure, but the scalp is numbed so you don't feel any pain.
Like all operations, surgery for a subdural haematoma carries a risk of complications. Most of these complications are uncommon, but they can be serious.
Some of the main problems that can occur after subdural haematoma surgery include:
There's also a chance that not all of the haematoma can be removed and that some of the symptoms you had before surgery continue. These may get better over time or they may be permanent.
In some cases, thehaematomacan come back during the days or weeks after surgery. If this happens, further surgery may be needed to drain it again.
If surgery goes well and you don't have any complications, you may be well enough to leave hospital after a few days. If you do develop complications, it may be several weeks before you're able to go home.
If you have persistent problems after surgery, such asmemory problems or weakness in your limbs, you may need further treatment to help you gradually return to your normal activities.
The length of time it takes to recover from a subdural haematoma will vary from person to person. Some people will feel a lot better after a few weeks, while othersmay never make a full recovery.
