OBJECTIVE: Intracranial vertebrobasilar artery dissection (iVBD) is an important etiology for posterior circulation ischemic stroke (PCS); however, its long-term functional outcome has been seldom reported. The present study aimed to elucidate the functional outcomes and the predictors of poor functional recovery at 1-year after iVBD-caused PCS. METHODS: Patients with iVBD-caused PCS who had been recruited in the Stroke Registry of Taipei Veterans General Hospital between January 1, 2012 to February 28, 2014 were included...

Vertebrobasilar dolichoectasia (VBD) is a rare dilative arteriopathy defined as elongation or widening of the intracranial vertebral and/or basilar arteries. The prevalence ranges from 0.06% to 5.8%. The majority of VBDs are asymptomatic. Downbeat nystagmus has been reported as a component of an infrequent ocular movement disorder in VBD. Nevertheless, oculopalatal tremor (OPT), delayed sequelae of a brainstem lesion, has never been demonstrated in VBD cases. Synchronized rhythmic involuntary contractions of the soft palate with an ocular pendular nystagmus, predominantly vertical pendular nystagmus, are the hallmark presentation...

PURPOSE: Giant intracranial aneurysms commonly cause poor clinical outcome and few studies focus on them. This study is to retrospectively report the angiographic and clinical presentations in unruptured giant saccular vertebrobasilar aneurysms with and without endovascular treatment. METHODS: Out of 400 patients who had unruptured posterior circulation aneurysms in a single center, we found 10 unruptured giant (>25mm) saccular vertebrobasilar aneurysms. Clinical and angiographic presentations as well as their clinical outcomes were assessed...

Vertebrobasilar dolichoectasia (VBD) is characterized by ectasia, elongation, and tortuosity of the vertebrobasilar arteries, with a high degree of variability in clinical presentation. The disease origin is believed to involve degeneration of the internal elastic lamina, thinning of the media secondary to reticular fiber deficiency, and smooth muscle atrophy. The prevalence of VBD is variable, ranging from 0.05% to 18%. Most patients with VBD are asymptomatic and their VBD is detected incidentally; however, it is important to recognize that the presence of symptoms, which can lead to clinically significant morbidity and sometimes mortality, may influence clinical management...

BACKGROUND AND PURPOSE: Although intracranial atherosclerotic disease is often encountered during endovascular treatment for acute vertebrobasilar occlusions, its clinical implication is not well-known. We aimed to evaluate whether intracranial atherosclerotic disease influences the clinical outcomes following endovascular treatment of acute vertebrobasilar occlusive stroke. MATERIALS AND METHODS: Fifty-one patients with acute vertebrobasilar occlusive stroke were included...

Vertebrobasilar (VB) intracranial dissecting aneurysms (IDAs) pose difficult therapeutic issues and are especially among the most difficult to manage surgically. There are, however, some cases where selective aneurysm obliteration by endovascular approach is impossible or is associated with an unacceptable risk of morbidity. This is particularly true when the aneurysm is dissecting, giant, or has a large neck. In such cases, surgical treatment may be the only alternative. Optimal management of these lesions is therefore challenging and treatment decisions have to be made on a case-by-case basis...

BACKGROUND: High-resolution magnetic resonance vessel wall imaging (HRMR-VWI) has been used to explore vascular diseases such as vasculitis and vulnerable plaque of intracranial arteries. Although vessel wall inflammation is suspected as one of the causes of cerebral arterial dissection, there have been few reports regarding the application of HRMR-VWI to arterial dissection. We have therefore evaluated the efficacy of HRMR-VWI in patients with vertebrobasilar artery dissection. METHODS: HRMR-VWI was performed on 5 patients who had been diagnosed with nonhemorrhagic vertebrobasilar artery dissection...

OBJECTIVE Large vertebrobasilar fusiform aneurysms (VFAs) represent a small subset of intracranial aneurysms and are often among the most difficult to treat. Current surgical and endovascular techniques fail to achieve a complete or acceptable result because of complications, including late-onset basilar artery thrombosis and perforator infarction. The parallel-stent placement technique was established in the authors' department, and this study reports the application of this technique in the treatment of unruptured VFAs...

INTRODUCTION: According to the literature, a fusiform aneurysm located in the cerebellopontine angle (CPA) is an extremely rare condition. CASE OUTLINE: We report a case of a 59-year-old patient with initial dizziness and left-sided sensorineural hearing loss that had gradually developed over six months. Vertebrobasilar fusiform aneurysm, with intraluminal thrombus, which was displaced to the right cerebellopontine angle, creating mass effect, was diagnosed using brain magnetic resonance imaging and magnetic resonance angiography...

OBJECTIVES: Symptomatic intracranial vertebrobasilar artery stenosis (IVBS) carries a high annual risk of recurrent stroke. Endovascular therapy was a promising technique but recent trials suggest it may carry a risk of periprocedual complications especially in inexperienced hands. This prospective study was to evaluate the safety of endovascular therapy for severe symptomatic IVBS in a high volume stroke centre. PATIENTS AND METHOD: Patients with symptomatic IVBS caused by 70-99% stenosis despite medical treatment of at least one antiplatelet agent and statin were enrolled...

Vertebral artery fenestration is accidentally detected during angiography or autopsy. Spontaneous deep nuclear hemorrhage in association with vertebral artery fenestration is a very unusual finding in angiography. Such an unusual finding has not been reported in the English literature. Here, we report two cases of spontaneous deep nuclear hemorrhage that presented with features of raised intracranial pressure. Computed tomography revealed a deep nuclear acute bleed in both cases. Digital subtraction angiographic findings were normal other than the presence of a long segment vertebral artery fenestration...

Persistent primitive hypoglossal artery (PPHA) is a rare embryonic carotid vertebrobasilar artery anastomosis. Hypoglossal artery arises from the internal carotid artery (ICA) between the C1 and C2 vertebral levels and traverses through the hypoglossal canal to join the vertebro-basilar system. We present a rare case of an anomalous right sided PPHA as a sole supply to posterior circulation of brain with absent/hypoplastic bilateral vertebral arteries in a two year child who had presented with acute left sided haemiplegia...

BACKGROUND: Many previous experimental studies of blast wave effects have reported vascular and parenchymal injury in brains extracted from the skulls prior to histopathological assessment. Brain removal disrupts vasculature and structural features of the meninges that may be sources of signs and symptoms of mild traumatic brain injury, particular at lower blast overpressures (<5 psi peak). NEW METHOD: Immunohistochemical and histopathological studies have been conducted in sections from decalcified, paraffin embedded, histologically sectioned whole rat heads...

BACKGROUND AND OBJECTIVES: Pompe disease is a rare metabolic disorder due to lysosomal alpha-glucosidase (GAA) deficiency. It is considered as a multi-systemic disease since, although glycogen accumulation is largely prominent in heart, skeletal and respiratory muscles, other organs can also be affected. As regards the vascular system, few reports have documented cerebrovascular malformations in Pompe patients. The aim of this study was to define the presence and type of intracranial arterial abnormalities in a cohort of late onset Pompe disease (LOPD) patients...
