In medicine, hypoplasia is called insufficient development, both congenital and acquired. This also applies to the blood vessels that supply the brain. Hypoplasia of the left vertebral artery is characterized by a narrowing of its lumen, because of which the biological fluid does not reach the tissues in the required amount.
Symptoms and signs of hypoplasia of the left vertebral artery
Considered pathology for a long time may not manifest itself, as the clinic of the disease grows gradually and very slowly. When the stage of the defeat of the vessel is sufficiently developed, there are such clinical signs:
- headache and occasional dizziness;
- a significant increase in blood pressure due to compensation of blood supply deficiency;
- weakness, especially in the limbs;
- violations of coordination of movements ;
- deterioration of sensitivity in the fingers;
- decreased quality of vision;
- nervous disorders.
As a rule, the symptomatology after a certain period becomes less pronounced, since the brain corrects the work of the vascular system and restores blood circulation by increasing the load on other arteries. If such compensation does not occur, the patient may completely or partially lose his ability to work. In such cases, with hypoplasia of the left vertebral artery, a disability is registered. For this procedure it is necessary to make a number of laboratory tests, after which the doctors' commission will decide on the expediency of granting this status.
Treatment of hypoplasia of the left vertebral artery
Conservative therapy of the described disease consists in the normalization of blood circulation. Pharmacological
In severe forms of hypoplasia of the left vertebral artery, surgery is indicated. Usually, angioplasty or stenting of the vessel is prescribed. Despite the high efficiency of surgical interventions, they are not performed at stages 3 and 4 of the disease due to the risk of damage to the walls of the artery.
