Vertebrobasilar dolichoectasia (VBD) is characterized by significant dilation, elongation, and tortuosity of the vertebrobasilar system. We present a unique case of VBD, confirmed by neuroimaging studies, showing vascular compression of the right optic tract and lower cranial nerves leading to an incongruous left homonymous inferior quadrantanopia and glossopharyngeal neuralgia.

BACKGROUND: The aim of this study was to analyse the morphometry of the intracranial segment of the vertebral artery in the context of clinical usefulness. The results were compared with published data available in full-text archived medical journals. MATERIALS AND METHODS: More than 100 DSA (digital subtraction angiography) and 3D angio-CT (computed tomography) examinations were used to measure the following parameters: the whole and partial length of V4 in characteristic anatomical points, the diameter in three places (on the level of foramen magnum, in point of exit to the PICA, and in the vertebro-basilar junction), the angle of connection to the VAs, and all anatomical variations including fenestration, duplication, dolichoectasia or absent artery...

BACKGROUND AND PURPOSE: Among patients with vertebrobasilar dolichoectasia is a subset of patients with disease affecting the anterior circulation as well. We hypothesized that multivessel intracranial dolichoectasia may represent a distinct phenotype from single-territory vertebrobasilar dolichoectasia. The purpose of this study was to characterize clinical characteristics and angiographic features of this proposed distinct phenotype termed "diffuse intracranial dolichoectasia" and compare them with those in patients with isolated vertebrobasilar dolichoectasia...

A 78-year-old man was admitted to our hospital because of sudden right hemiparesis and dysarthria. His cranial MRI showed an area of hyperintensity in left pons on DWI and MRA revealed dilated, elongated and tortuous intracranial artery. We diagnosed as acute phase ischemic stroke and intracranial arterial dolichoectasia (IADE). Intravenous infusion of rt-PA was performed 157 minutes after the onset of symptoms, and his hemiparesis improved. However, he subsequently suffered from cerebral infarction 4 times in 6 months, and we treated him twice with thrombolytic therapy...

If the origin of isolated abducent nerve palsy cannot be found on neuroradiological examinations, diabetes mellitus is known as a probable cause; however, some cases show no potential causes of isolated abducent nerve palsy. Here, we report a 74-year-old male who suffered from diplopia due to isolated left abducent nerve palsy. Magnetic resonance angiography and fast imaging employing steady-state acquisition imaging clearly showed a dolichoectasic vertebrobasilar artery compressing the left abducent nerve upward and outward...

BACKGROUND AND PURPOSE: Dolichoectasia of the basilar artery is a characteristic finding of Fabry disease. However, its prevalence, severity, and course have been poorly studied. This study quantitatively evaluated, by MRA, a panel of basilar artery parameters in a large cohort of patients with Fabry disease. MATERIALS AND METHODS: Basilar artery mean diameter, curved length, "origin-to-end" linear distance (linear length), and tortuosity index ([curved length ÷ linear length] - 1) were retrospectively measured on 1...

BACKGROUND AND PURPOSE: Vetebrobasilar dolichoectasia is characterized by arterial elongation, dilation, and tortuosity and leads to high risks of ischemic stroke. Our aim was to investigate the differential susceptibility to elastase-induced vertebrobasilar dolichoectasia induction in 2 different mouse strains. MATERIALS AND METHODS: Elastase (25 mU) was injected into the cisterna magna in C57BL/6J (n = 36) and 129/SvEv (SV129) (n = 36) mice. Control animals were injected with heat-inactivated elastase (n = 12 for each strain)...

BACKGROUND AND PURPOSE: Non-saccular aneurysms of the posterior fossa are an uncommon pathology with no clear treatment strategy. The use of flow-diverting stents (FDS) has had mixed results. We sought to evaluate our experience of FDS for the treatment of this pathology. METHODS: We retrospectively reviewed our database of prospectively collected information for all patients treated only with flow diversion for an unruptured non-saccular aneurysm of the posterior circulation between February 2009 and April 2016...

A 47-year-old male presented with a 2-year history of hemifacial spasm. Magnetic resonance imaging performed showed his tortuous basilar artery with nerve compression, and the patient was treated conservatively with botulinum toxin injections with complete resolution of symptoms. This rare disease was caused by his long history of hypertension, which led to his major basilar artery dolichoectasia.

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...

BACKGROUND: Hemifacial spasm (HFS) is frequently caused by vascular compression of the facial nerve. Vertebrobasilar dolichoectasia (VBDE) may cause vascular crowding in the limited space of the posterior fossa, increasing the chance of vascular compression of the facial nerve. We investigated the prevalence of VBDE in HFS. METHODS: We analyzed the presence of VBDE on 3.0 T magnetic resonance images in patients with HFS and control subjects; age, sex and hypertension were matched...

INTRODUCTION: Vertebrobasilar dolichoectasia is a condition in which there is elongation and dilatation of the vertebral and basilar arteries. Few studies have been reported that focus on cases of trigeminal neuralgia (TN) secondary to vertebrobasilar dolichoectasia (VD) and treated by microvascular decompression (MD). PATIENTS AND METHODS: A case is presented of trigeminal neuralgia caused by vertebral artery compression. An analysis of the microsurgical technique, as well as a systematic review of the literature about this uncommon nerve compression is performed, in order to investigate, by pooled case analysis, if MD is a good option for this type of patient...

Vertebrobasilar dolichoectasia (VBD) is a chronic disorder with various cerebrovascular and compressive manifestations, involving subarachnoid hemorrhage (SAH). Occurrence of SAH shortly after worsening of clinical VBD symptoms has occasionally been reported. The goal of the study was to examine this association, in particular its pathophysiology, clinical precursor signs, time course, and outcome.To this end, in a retrospective multicenter study, we analyzed 20 patients with VBD and SAH in regard to preceding clinical symptoms, presence of vertebrobasilar thrombosis and ischemia, outcome and neuropathological correlates...

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...
