WHERE IS EVD INSERTED?

A brain infection known as encephalitis can be brought on by a variety of viruses. For a variety of reasons, some viruses are more likely to cause encephalitis than others. The virus must first enter the body in order to cause encephalitis. There are several possible entry points, but the most common is through the respiratory tract. Once inside the body, the virus can travel to the brain through the bloodstream or along the nerves.

How Is the EVD Procedure Performed?

The EVD is a thin, flexible tube that is inserted into the ventricle in the brain. The ventricle is a space filled with cerebrospinal fluid (CSF). The EVD is used to drain CSF from the brain.

The procedure is usually done in the operating room under general anesthesia. The doctor will make a small incision in the scalp and then drill a tiny hole in the skull. The EVD is then inserted into the hole and advanced into the ventricle. The EVD is then connected to a drainage bag.

Benefits vs Risks

The main benefit of the EVD is that it can help to relieve increased intracranial pressure (ICP). ICP is the pressure inside the skull. When ICP is too high, it can damage brain tissue. The EVD can also be used to administer medications directly into the brain.

Risks

There are also some risks associated with the EVD procedure. These include:

• Infection
• Bleeding
• Stroke
• Seizures
• Headache
• Nausea
• Vomiting

Who Needs an EVD?

The EVD is used to treat a variety of conditions, including:

• Hydrocephalus
• Meningitis
• Encephalitis
• Subarachnoid hemorrhage
• Intraventricular hemorrhage
• Brain tumors

When Is the EVD Inserted?

The EVD is usually inserted as soon as possible after the diagnosis is made. The sooner the EVD is inserted, the sooner the ICP can be reduced and the damage to the brain can be prevented.

Concluding Remarks

The EVD is a life-saving procedure that can help to treat a variety of conditions. The procedure is usually safe and effective, but there are some risks associated with it. The EVD is usually inserted as soon as possible after the diagnosis is made.
