Because the brain stem and spinal cord are responsible for most of the body’s functions, the anomaly of Arnold Chiari manifests with wide variety of symptoms. Patients have various complaints, from a headache to an intestinal disorder.

Arnold Chiari’s anomaly symptoms.

There are 4 most common symptoms of Chiari anomaly:

• a headache of a pressing nature in the nape, which is enhanced by physical exertion and cough, often with pain in the neck;
• difficulty of swallowing;
• weakness and decreased sensitivity in the limbs;
• violation of coordination and balance.

This condition can remain asymptomatic for a long time. It can manifest in adolescence during a period of active growth or in adults. In this case, there is a whole list of symptoms that may indicate this anomaly:

– the headache usually begins with the occipital region;

– dizziness;

– pain in the neck;

– numbness in the hands

– abnormal sensations in the fingers;

– awakening in the middle of the night due to numbness of the hand;

– feeling of lack of air;

– pressure behind the sternum;

– constipation.

Symptomatology can differ in different patients and does not necessarily correspond to the degree of wedging of the tonsils of the cerebellum. Some patients with significant levels of tonsillitis do not have any symptoms. In turn, patients with a slight incidence may experience severe symptoms. When symptoms are present, they are often fuzzy, blurred and nonspecific, and as a result, Аrnold Chiari anomaly can’t be diagnosed for a long time. The appearance of symptoms is a consequence of a disturbance of the cerebrospinal circulation and compression of the nervous structure. In some cases, damage to the head or neck as a result of trauma can trigger the onset of the disease.

Therapeutic tactics depends on the type of malformation and the severity of the symptoms of Arnold Chiari’s syndrome.
Thus, the degree of anomaly is differentiated depending on the displacement of the cerebellar tonsils in the grete occipital foramen, disturbances in the position of the brainstem and the correlation of the structures of the craniocervical junction:
the 1st degree. It appears in adolescence or in adults, and according to statistics the peak of symptoms in adults falls on 40-50 years, which has not yet been explained.
anomaly arnold kiari 2 degrees, 3 degrees. Is manifested in early childhood or adolescence.
Anomaly of the arnold kiari of the 4th degree. It leads to the fact that newborns with such a diagnosis are not viable and die in the first days or weeks after birth.

If the symptoms are mild or moderate, the following may be effective:

• a certain way of life;
• proper nutrition;
• drug therapy.

When the patient has an anomaly of Arnold Chiari, we diagnose in him that the amygdala of the cerebellum is shifted downward into the large occipital foramen. At the same time, the medulla oblongata receives pressure, and this leads to neurological disorders. In the case of severe symptoms or progressive deterioration of the patient’s condition, surgical treatment is required to remove part of the occipital bone and part of the dura mater. This leads to the elimination of compression of the brain structures and the creation of space for the cerebellum and brainstem.

According to literature data and in our experience, the best treatment results are observed when patients are operated on during the first 2 years after the beginning of symptoms. Asymptomatic patients can be observed and operated later if they have symptoms. But it is important to remember that the changes, as a consequence syndrome and hydromia, are growing slowly, and patients often do not pay attention to them until gross manifestations appear. At the same time, already developed violations of the function, as a rule, are irreversible, therefore, the operation should be aimed at preventing their development. As a result of surgical treatment, most of the complaints and symptoms regress in the early postoperative period. A person returns to his functionally full life, provided that irreversible atrophic changes did not develop before the operation.

The first operation in Ukraine about the Arnold-Chiari anomaly in an adult was performed in our clinic in 1995. (after the training of Dr. Fedirko V.O. in Canada). The number of surgeries exceeded several hundred, and the efficiency of the symptomatic regression after operation is at the level of 94-97%.
