Pneumoencephalography Dry

Pneumoencephalography (PEG) is a method for diagnosing and treating brain diseases based on the introduction of gas into the cranial cavity. Currently, there are several methods of PEG, but the most common is dry PEG.

Dry PEG is a procedure in which gas is injected into the cranial cavity without removing cerebrospinal fluid (CSF). This allows you to get a clearer image of the brain and its structures.

The dry PEG procedure is performed under local anesthesia and takes about 15-20 minutes. The patient is in a supine position on a special table. The doctor inserts a thin tube into one of the side openings of the skull and slowly pumps gas into the cranial cavity until the desired pressure is achieved. After this, the gas is slowly released from the cranial cavity, and the doctor takes pictures of the brain using special equipment.

One advantage of dry PEG is that it provides clearer images of the brain, especially when there is fluid in the cranial cavity. This can be useful in diagnosing brain tumors, as well as in assessing the condition of blood vessels and other structures of the brain.

However, dry PEG also has its disadvantages. One of them is that headache or nausea may occur when the gas is administered. In addition, complications such as damage to blood vessels or nerves may occur during the procedure.

In general, dry PEG is an effective method for diagnosing and treating many brain diseases. However, before undergoing this procedure, you should consult with your doctor and discuss all possible risks and benefits.

**Pneumoencephalography** (PEG) is a research method that involves introducing gas under high pressure into the cranial cavity through the nasal passages or through burr holes in the skull to facilitate the recognition of certain mental illnesses and brain injuries and to determine the depth of brain lesions.

The widespread use of PEG became possible after the invention of a special instrument - a PEG chamber, which consists of several main elements. The body is a rigid hemispherical cap with a protrusion-nose on which the gas tank rests. On the outside, the body is covered with a soft-holding fabric made of foam rubber (for shock absorption). The camera also has a two-way pneumatic valve, handles, a transport case and a thread measuring pressure inside the skull. A polyethylene tourniquet is placed between the soft spout of the camera and the walls of the skull, allowing you to better feel the bony protrusion - the cockscomb. The tourniquet is fixed with metal clamps and tightened in persons with a pronounced frontal structure of the skull. Inside the chamber there is a gas cushion with oxygen and carbon dioxide. The camera connects to the ballo
