Comparative analysis of the groups of patients with idiopathic bilateral vestibular hypofunction and a group of vestibulopathy patients with vertebrobasilar insufficiency demonstrated identity of the basic and additional diagnostic parameters in these syndromes as well as similarity in clinical diagnostic and anamnesis data. In all cases, functional assessment of endothelium-dependent vasodilation and selected biochemical marker sICAM-1 revealed endothelial dysfunction. Drug correction of endothelial dysfunction positively affected the manifestations of major and minor features of the syndrome, which confirmed the contribution of endothelial functional disturbances to the pathogenesis of bilateral vestibular hypofunction...

INTRODUCTION: Percutaneous endovascular therapy is an accepted and preferred procedure for symptomatic subclavian artery disease. However, the technical feasibility and effectiveness of treating chronic total occlusion of the subclavian artery with this approach is uncertain. We aimed to evaluate the initial and mid-term results of endovascular therapy for patients with symptomatic chronic total occlusion of the left subclavian artery. METHODS: Consecutive patients who underwent balloon angioplasty and stenting for chronic total occlusion of the left subclavian artery between January 2010 and February 2014 were included...

BACKGROUND: Vertebrobasilar insufficiency vertebrobasilar (VBIV) is a serious nerve disease and many old people suffer from it. Acupuncture has been widely applied in the treatment of VBIV. However, to our knowledge, there has been no systematic review or meta-analysis of randomized controlled trails regarding the effectiveness of this treatment. Here, we provide a protocol to evaluate the effectiveness and safety of acupuncture for VBIV. METHODS: Relevant randomized controlled trials in 5 databases (EMBASE, PubMed, the Cochrane Central Register of Controlled Trials [Cochrane Library], Chinese Biomedical Literature Database [CBM], China National Knowledge Infrastructure [CNKI]) will be comprehensively searched by 2 researchers in December 2017...

Beauty parlor stroke syndrome (BPSS) is a rare condition characterized by mechanical impingement of a vertebral artery (VA) during neck rotation and/or hyperextension followed by vertebrobasilar insufficiency. However, there have been no reports of BPSS in which the cause of mechanical impingement was identified and no cases for which surgical treatment was reported. The authors report the case of a 56-year-old Japanese man who presented with presyncope that occurred during cervical extension. Given the possibility of vertebrobasilar insufficiency, digital subtraction angiography and CT angiography were performed...

Cerebral ischemia because of vertebrobasilar insufficiency (VBI) rarely presents as an initial sign within the systemic lupus erythematosus (SLE) population, and there are very few case reports supporting this manifestation. This report details 3 different patients with SLE who experienced VBI as an initial manifestation. Patient 1 was a 24-year-old female who developed a bilateral pontine lesion as a consequence of basilar artery stenosis. Patient 2 was a 34-year-old male with an acute ischemic lesion on the right side of his cerebellum and pons because of significant stenosis in the distal segment of the right vertebral artery...

BACKGROUND: Endovascular coil embolization is an accepted treatment option for intracranial aneurysms. However, the coiling of aneurysms with an incorporated artery (IA) poses a high risk of IA occlusion. Here we report our experience of endovascular coil placement using a technique that avoids IA occlusion in aneurysms with IAs. METHODS: Over a 6-year period, 185 patients harboring 206 intracranial aneurysms underwent endosaccular coiling. Forty-two of these patients with 45 aneurysms were treated by coil placement to avoid IAs occlusion...

Rotational vertebral artery occlusion (RVAO) is a well-documented surgically amenable cause of vertebrobasilar insufficiency. Traditionally, patients have been imaged using dynamic rotational angiography. We report a case of RVAO in which intraoperative indocyanine green angiography (ICGA) was used to confirm adequate surgical decompression of the VA. A 57-year-old female who presented with multiple episodes of syncope provoked by turning her head to the right. Rotational dynamic angiography revealed a dominant right VA that became occluded at the level of C5/6 with head rotation to the right...

Vertebrojugular fistulas have been described in the literature associated with blunt or penetrating injury and iatrogenic or spontaneous development. Its presentation may be broad and may include symptoms of radiculopathy, vertebrobasilar insufficiency, tinnitus, and bruit. However, so far, no direct cardiac complications had been reported. Here, we describe a case of an 86-year-old female who suffered a C5 vertebral fracture secondary to a ground-level fall that was initially treated conservatively due to the onset of new severe atrial fibrillation...

Vertebrobasilar insufficiency (VBI) provoked by physiological head rotation is known as rotational vertebral artery syndrome (RVAS) or Bow Hunter syndrome. RVAS most often occurs at C1-2 level with head rotation and presents with symptoms of VBI. Several previously published studies have reported RVAS at subaxial sites (V2 segment), however, tumor-induced RVAS has never been reported. The authors report the first case of RVAS at V2 segment due to compression from a spinal tumor. A 71-year-old man presented with symptoms of dizziness provoked by head rotation or neck extension...

BACKGROUND: Rotational vertebral artery occlusion is a rare syndrome characterized by vertebrobasilar insufficiency secondary to position-dependent occlusion of the vertebral artery. Most cases reported in the literature have been attributed to osteophytic compression, either from the occipital condyle or within the transverse foramen. However, vertebral artery dissection secondary to motion in the setting of anomalous anatomy has not been reported. CASE DESCRIPTION: To the authors' knowledge, rotational vertebral artery occlusion and dissection secondary to anomalous entrance into the transverse foramen have never been reported...
