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...

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...

BACKGROUND: Vertebrobasilar dolichoectasia (VBD) is a rare vasculopathy. The etiology of this disease is unknown. Transient ischemic attacks (TIAs) of vertebrobasilar system refer to a transient (< 24 hours) lowering of blood flow in the posterior circulation of the brain. We present a case of dolichoectasia in the vertebrobasilar artery that presented with TIAs. CASE REPORT: A hypertensive 54-year-old man with true vertigo, nausea, imbalance, dysarthria, dysmetria, horizontal nystagmus, and gait ataxia was referred to Alzahra Hospital, Isfahan, Iran...

BACKGROUND: Screening for Fabry disease (FD) in high risk populations yields a significant number of individuals with novel, ultra rare genetic variants in the GLA gene, largely without classic manifestations of FD. These variants often have significant residual α-galactosidase A activity. The establishment of the pathogenic character of previously unknown or rare variants is challenging but necessary to guide therapeutic decisions. OBJECTIVES: To present 2 cases of non-classical presentations of FD with renal involvement as well as to discuss the importance of high risk population screenings for FD...

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...

Hemifacial spasm (HFS) happens because of vascular compression of the facial nerve at the root exit zone. Vertebrobasilar dolichoectasia (VBD) is a very rare cause of HFS. VBD is diagnosed by computed tomography angiography and magnetic resonance imaging. Here, we report a case of 65-year-old female patient with HFS due to VBD. We discuss the complications and the treatment options for the case.

Vertebrobasilar dolichoectasia is a clinical entity associated rarely with obstructive hydrocephalus. We present a 48-year old male with a profound dilatation of the ventricular system due to a dolichoectatic basilar artery, as appeared in imaging studies. The patient suffered from longstanding hydrocephalus and presenile dementia. The underlying mechanism for obstructive hydrocephalus due to vertebrobasilar dolichoectasia is considered to be both a water-hammer effect and a direct compression of adjacent structures...

The term "vertebrobasilar dolichoectasia" refers to anomalous dilatation of the intracranial arteries associated with elongation or tortuosity of the affected vessels. The etiology of the disease is unknown and is usually detected incidentally. The predominant clinical manifestations arise due to the mass effect of the dilated vessels and may include cranial nerve compression, extrinsic aqueductal compression, motor and sensory disturbances. Trigeminal hypoplasia is a very uncommon condition, usually described in association with Goldenhar-Gorlin syndrome and has not yet been attributed to vertebrobasilar dolichoectasia...

The anatomy of the arterial system supplying blood to the brain can influence the development of arterial disease such as aneurysms, dolichoectasia and atherosclerosis. As the arteries supplying blood to the brain develop during embryogenesis, variation in their anatomy may occur and this variation may influence the development of arterial disease. Angiogenesis, which occurs mainly by sprouting of parent arteries, is the first stage at which variations can occur. At day 24 of embryological life, the internal carotid artery is the first artery to form and it provides all the blood required by the primitive brain...

Vascular compression of medulla or spinal cord at the cervico-medullary junction has been commonly described in the literature and is often attributed to dolichoectasia of the vertebrobasilar arteries. We describe a case of anomalous course of the cervical segments of the bilateral vertebral arteries which were seen entering the spinal canal directly after exiting the transverse foramen of axis and causing significant cord compression at the cervico-medullary region leading to spastic quadriparesis.

OBJECTIVE: Cerebrovascular abnormalities have been reported in adult patients with Pompe disease. The objective was to study these abnormalities by (1) determining the diameter and mean flow velocity (MFV) of large cerebral arteries and (2) estimating cerebral blood flow (CBF), resistance index (RI) and cerebrovascular reactivity (CVR) as functions of resistance vessels. METHODS: In ten adults with Pompe disease and twenty controls, the diameter, peak systolic (PSV) and end-diastolic velocities (EDV) of arteries supplying the brain were quantified by MR angiography and sonography...

Hemifacial spasm (HFS) due to direct compression of the facial nerve by a dolichoectatic vertebrobasilar artery is rare. Vessels are often non-compliant and tethered by critical brainstem perforators. We set out to determine surgical strategies and outcomes for this challenging disease. All patients undergoing surgery for HFS secondary to vertebrobasilar dolichoectasia were reviewed. Hospital records, clinic notes and radiographic imaging were collected for outcome measures. Seventeen patients (eight males, nine females) were identified...

BACKGROUND AND PURPOSE: Vertebrobasilar dolichoectasia (VBD) is a dilatative arteriopathy associated with a decreased blood flow velocity. Fluid attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) is a phenomenon most likely representing slow arterial blood flow. We sought to examine the frequency and extent of FVH in VBD. METHODS: We analyzed magnetic resonance imaging (MRI) findings in 77 VBD patients with special emphasis on FVH in relation to the diagnostic MRI criteria of VBD and the etiology in symptomatic patients...
