The article presents the results of clinical neurological and neuro-orthopedic examination of 48 patients with symptoms of vertebrobasilar insufficiency associated with complications of osteochondrosis. The main clinical syndromes that were observed in this group of patients were highlighted, the general characteristics of cardiovascular pathology, changes in brain during MRI examination and the severity of arterial sclerotic disease during ultrasound examination of the main arteries of the head and neck was given. On the basis of neuro-orthopedic examination of the cervical spine, specifically during examination of the active and passive range of movements, functional disorders in the form of restriction of movements were defined. By means of palpation, provocative and specific tests for certain motor segments, the main etiopathogenetic mechanisms of these disorders were identified. The program of clinical treatment was based on medical history, assessment of factors in the diagnosis of heart disease, analysis of cerebral blood circulation disorders in anamnesis, as well as provocative factors, which were overwhelmed by development. Surrounding the neuro-orthopedic examination of the neuro-orthopedic examination. The withers, they swallowed respect for a volume of rugs in the sheer ridge, conducted the Glison test, provocative tests on movements segments, palpation and percussion. The main types of postural disorders in patients with vertebral artery syndrome of extravasal origin have been investigated. As a result of clinical and neuro-orthopedic comparison, a higher frequency of Barre-Lieou syndromes, vestibulo-ataxic and vestibulo-cochlear disorders in patients with round posture was found, while the syndrome of ophthalmic disorders was observed with equal frequency in patients with round (70,8%) and round-incurvate (74,0%) posture and significantly more often compared to the group of patients with normal posture (49,9%). Vestibulo-ataxic syndrome was significantly more frequent at suspicion on facet syndrome or uncovertebral arthrosis (58,8%) in comparison with the group of patients with suspicion on protrusion / herniated intervertebral disc (11,8%).

Abstract Intracranial vertebral endarterectomy was performed on six patients with vertebrobasilar insufficiency in whom medical therapy failed. The patients underwent operations for stenotic plaque in the intracranial vertebral artery with the opposite vertebral artery being occluded, hypoplastic, or severely stenosed. In four of the patients, the stenosis was mainly proximal to the posterior inferior cerebellar artery (PICA). In this group, after endarterectomy, the vertebral artery was patent in two patients, and their symptoms resolved: in one patient the endarterectomy occluded, but the patient's symptoms improved; and in one patient the endarterectomy was unsuccessful, and he continued to have symptoms. In one patient, the plaque was at the origin of the PICA. The operation appeared technically to be successful, but the patient developed a cerebellar infarction and died. In one patient the stenosis was distal to the PICA. During endarterectomy, the plaque was found to invade the posterior wall of the vertebral artery. The vertebral artery was ligated, and the patient developed a Wallenburg syndrome. The results of superficial temporal artery to superior cerebellar artery anastomosis are better than those for intracranial vertebral endarterectomy for patients with symptomatic intracranial vertebral artery stenosis. The use of intracranial vertebral endarterectomy should be limited to patients who have disabling symptoms despite medical therapy, a focal lesion proximal to the PICA, and a patent posterior circulation collateral or bypass.

Abstract Rotational vertebral artery (VA) occlusion syndrome, also known as bow hunter's syndrome, is an uncommon variant of vertebrobasilar insufficiency typically occurring with head rotation.1-3 The most common presenting symptom is dizziness (76.8%), followed by visual abnormalities and syncope (50.4% and 40.4%, respectively).2 Osteophytic compression due to spinal spondylosis has been shown to be the most common etiology (46.2%), with other factors, such as a fibrous band, muscular compression, or spinal instability, being documented.1,2 Treatment is dependent on the level and site of VA compression with anterior, anterolateral, or posterior approaches being described.1,4 We present the case of a 72-yr-old male with osteophytic compression of the V3 segment of the vertebral artery at the occipital-cervical junction. The patient underwent a C1 hemilaminectomy and removal of osteophytic compression from the occipital-cervical joint. The patient had complete resolution of compression of his vertebral artery on postoperative imaging and remained neurologically intact following the procedure. We review the literature on this topic, the technical nuances of the procedure performed, and review the different treatment modalities available for this rare condition.1-11  The patient consented to the procedure and to publication of their image.

The results of experimental studies made it possible to draw a conclusion on the reality of cerebral vessels reactivity recovery using drugs with primary neurometabolic activity, in particular, dimephosphone, sermion and pyracetam. The advantages of low-toxic nonauticholinesterasic organic phosphorus compounds among the correctors of regulatory mechanisms of circular provision of the brain are shown.

Vertebral artery disease (VAD) is a significant cause of severe symptoms or stroke. Approximately 25 to 30% of strokes involve the posterior circulation system; VAD will be present in 20% of these and will be the source in about 10%. The ability to properly diagnose, manage, and treat VAD is an important skill for practitioners caring for patients with extracranial cerebral occlusive disease. This review covers anatomy, presentations of VAD, evaluation, patterns of disease, treatment, and other vertebral artery (VA) syndromes. Tables outline symptoms and differential diagnoses of vertebrobasilar insufficiency, etiologies of VA compression syndromes, posterior circulation cerebrovascular accident symptoms and associated syndromes, and ultrasonography velocity and VA stenosis. Figures show the anatomy of the VA, circle of Willis, aberrant arteries, VA compression, ischemic posterior circulation, collateral pathways to the VA, common disease patterns in VAD, VA to carotid artery anastomosis, incision for the V3 bypass, VA aneurysm, VA dissection, angiography of the right VA, giant cell arteritis, and fibromuscular dysplasia. Radiologic videos are provided. This review contains 15 figures, 6 tables, 7 videos, and 71 references.
