vertebrobasilar insufficiency syndrome or vertebrobasilar arterial system is a reversible loss of functionality of the brain, which occurs due to insufficient blood supply to the area, fueled main and vertebral arteries.
cause of vertebral-basilar insufficiency is a stenosis of the great vessels: the nameless and subclavian arteries and the vertebral arteries extracranial.Most often these arteries patency violated because of atherosclerotic lesions.
symptoms of vertebral-basilar insufficiency
basis for diagnosing vertebral-basilar insufficiency is a characteristic set of symptoms, which combine several clinical symptoms:
- laryngeal and pharyngeal symptoms,
- vestibular disorders,
- oculomotor and visualdisorder,
- violations of motor coordination,
- vegetative-vascular dystonia,
- asthenic syndrome.
complex of symptoms observed in most patients with insufficient blood circulation in the vertebral-basilar region.A presumptive diagnosis shall be made in the presence of at least two of
All symptoms vertebral-basilar insufficiency conditionally divided into permanent and paroxysmal.Recurrent symptoms are observed for a long time and can be observed in the patient, even between attacks.Paroxysmal syndromes and symptoms are detected in ischemic attack.
Diagnostics vertebral-basilar insufficiency
the diagnosis of vertebral-basilar insufficiency used MRI, Doppler ultrasound, transcranial Doppler, duplex scanning, conventional radiography, x-ray contrast panangografiyu.
important role in the diagnosis of vertebral-basilar insufficiency assigned otoneurological study with computer and elektronistagmograficheskimi electrophysiological data on the auditory evoked potentials that give description of the state structures of the brain stem.
Treatment of vertebral-basilar insufficiency treatment
vast majority of patients with vertebral-basilar insufficiency held conservative methods in an outpatient setting.The neurological hospital placed patients with focal neurological deficit sharp as with an increase in arterial thrombosis in a large trunk may develop with steady stroke neurological deficit.
As an alternative to the imposition of medical treatment applied ekstraintrakranialnyh anastomoses, endarterectomy, angioplasty and stenirovanie respective vessels, in some cases, carried out thrombolysis.
Thus, patients should be dosed exercise, quit smoking and drinking alcohol, limit the amount of dietary salt.
If a positive effect is not observed, it is necessary to begin drug therapy.Elderly patients with stenotic lesions of cerebral arteries blood pressure should be reduced with caution, as a low pressure may develop vascular lesions of the brain.
the treatment of vertebral-basilar insufficiency along with antiplatelet and antihypertensive agents are used as vasodilators.
in complex treatment should include pain relievers (if needed), sleeping pills, anxiolytics, antidipresanty, drugs relieve dizziness.
advisable to conduct therapeutic exercises, acupuncture and physiotherapy.
