Wallenberg - Zakharchenko syndrome: symptoms, treatment methods
The syndrome of Valenberg - Zakharchenko is called a brain damage due to a violation of his blood supply. This syndrome is named in honor of scientists who practically simultaneously described it. It is often called dorsolateral medullary syndrome. There is a malaise due to an insult-like thrombosis of the posterior artery. It is she who is responsible for supplying the blood of the cerebellum.
Description of the disease
A person seldom loses consciousness in the Valenberg-Zakharchenko syndrome, but there are attacks of dizziness that provokes a loss of balance, as the cerebellar arteries suffer.
In addition, there is a hiccup or a urge to vomit, as well as a symptom of mild stunnedness.
To thrombosis may cause arteriosclerosis of the vessels. However, cases of endarteritis of the vertebral artery, in which the syphilitic type, or rheumvasculitis are not uncommon.
A slow thrombotic or non-thrombotic lesion occurs. The zone of the vertebral or basilar artery is most often affected.
Wallenberg - Zakharchenko syndrome occurs with periods of improvement in well-being and its worsening. But the process of disease progression takes place.
How can the syndrome manifest itself?
It can develop in five ways. It completely depends on where the pathology center is located and what clinical signs are available.
Consider the types of syndrome in more detail.
The main type of
Neurology Research Institute confirms that with this ailment the following symptoms occur:
- Horner's syndrome;
- dissociated sensory impairment of surfaces located in the middle and caudal zones of the Selder;
- cerebellar hemiataxy;
- paralysis of the muscles of the soft palate and vocal cords.
Rarer types of development of
What else could Wallenberg-Zakharchenko syndrome be? There are some less common forms. It happens that the lower portion of the variolium bridge is captured because the posterior lower cerebellar artery recedes strongly.
Often, with this type of ailment, there are manifestations of additional symptoms, divided into two groups - there is an inferiority of the sixth or seventh nerve.
When the tail sections in the medulla oblong destroy in the process, the retreat of the cerebellar artery decreases. There are the same ipsilateral symptoms as in the initial type of syndrome.
Often the appearance of triplegia or cross-hemiplegia. This is how the alternating syndrome of Wallenberg-Zakharchenko manifests itself.
When the center of the spinal cord of the trigeminal nerve or its spine is affected, another form of the Valenberg syndrome-Zakharchenko is also spoken.
There may be a disruption of the conductive pathways, which are responsible for the sensitivity of the opposite part of the face. There are no discordant changes in the upper sensitivity on the face. That is, those areas that belong to the Zelder zone. Can cover the face of hemihyesthesia surface susceptibility. There is an expansion of a painful focus, as the conductors on the other side of the face are turned on. This is characterized by the same signs as in the first type, only more extended.
Clinical Signs of
Syndrome What are the data on this subject from the Neurology Research Institute? With this syndrome, there are a wide variety of symptoms:
- is difficult for a person to swallow;
- his speech is broken;
- part of the soft palate ceases to be active;
- the vocal cords do not move well;
- , Horner's syndrome occurs;
- there are vestibular-cerebellar signs( empty movements of legs, arms, strong tremor, balance is disturbed);
- there are no temperature or pain sensations on the opposite side to the lesion;there is a headache on the side of the lesion or all over the face.
This is the most common manifestation of Wallenberg - Zakharchenko syndrome.
All these clinical signs are caused by the fact that the posterior lower cerebellar artery overlaps. The outer parts of the medulla obliterate as a result of this.
Namely, the place where the trigeminal nerve( descending and ascending bundles, sympathetic fibers) is located suffers.
Methods of treatment
Hemorrhage is absent most often, the death does not threaten the disease. But if it is not treated, then various life-threatening complications can develop. Therefore, if the above symptoms have appeared, then the measures should be taken immediately.
Once the Wallenberg-Zakharchenko syndrome first appeared, the vital functions of the brain must be stabilized, the swelling of the tissues removed. It is better to carry out all manipulations in the first hours after the attack.
Less damage will occur if assistance is provided in a timely manner. The recovery process will be easier and faster. With prolonged failure to provide assistance, irreversible changes occur, and this, in turn, provokes a person with disability.
If breathing is impaired, oxygen therapy is necessary. For this, a mask or artificial ventilation is used.
What else should I do?
Cardiac activity should be maintained, and also try to stabilize blood pressure at the normal level. After all, to the Wallenberg syndrome - Zakharchenko often leads precisely arterial hypertension. The patient on a regular basis should take drugs to reduce pressure.
In addition, cardiac glycosides and nitrates are prescribed. It is necessary to normalize coagulability of blood and its density. Neuroprotective cells of the brain are protected. With the help of special preparations, painful sensations are removed, muscles are relaxed. Also, anticonvulsant and sedative drugs are often prescribed.
