PURPOSE: To describe the use of a re-entry catheter in the endovascular treatment of left subclavian stenosis. MATERIALS AND METHODS: We present three patients where initial attempts at re-vascularisation using standard techniques were unsuccessful. An OUTBACK catheter was employed to facilitate re-entry in these patients. RESULTS: True lumen re-entry was achieved in all patients, leading to successful treatment of all stenoses. There was a lack of filling of the left vertebral artery post-angioplasty in one patient; this was not clinically significant...

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: Intrathoracic carotid bifurcation is a rare vascular anomaly, with only 8 cases reported. This vascular anomaly was recently correlated with Klippel-Feil syndrome, a rare congenital disorder involving fusion of the cervical vertebrae. METHODS: A 70-year-old deaf mute man was admitted to our department because of right hemiparesis and right sensory disturbance. He displayed no abnormalities associated with Klippel-Feil syndrome. Diffusion-weighted imaging revealed acute multiple infarcts in bilateral hemispheres...

Right aortic arch with aberrant left subclavian artery (RAA/aLSCA) is a rare aortic arch anomaly. The clinical association of aLSCA stenosis with RAA/aLSCA has not yet been fully elucidated. The aim of this study was to investigate the diagnosis, incidence, management and outcome of aLSCA stenosis in infants with prenatally diagnosed RAA/aLSCA. Ten fetuses who were diagnosed as having RAA/aLSCA in Kyushu University Hospital between January 2011 and December 2014 were enrolled. The maternal and child medical records were reviewed to investigate sex, gestational age at the fetal diagnosis, gestational age and body weight at birth, the findings of computed tomography (CT), Doppler ultrasonography of the vertebral artery and angiography, and the complications and outcomes of aLSCA stenosis...

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 has never been reported...

BACKGROUND: Reversal of flow in the vertebral artery (RFVA) is an uncommon finding on cerebrovascular duplex ultrasound examination. The clinical significance of RFVA and the natural history of patients presenting with it are poorly understood. Our objective was to better characterize the symptoms and outcomes of patients presenting with RFVA. METHODS: A retrospective review was performed of all cerebrovascular duplex ultrasound studies performed at our institution between January 2010 and January 2016 (N = 2927 patients)...

Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders...

Background and purpose Previous studies have suggested that atrial septal aneurysm is a potential risk factor for cerebral embolism. However, the association between the level of atrial septal protrusion and cerebral embolism is still unclear. The purpose of the present study was to assess the association between the maximal distance of atrial septal protrusion and cryptogenic stroke. Methods A total of 588 consecutive acute ischemic stroke patients (70 ± 11 (mean ± SD) years, 401 men) who underwent transesophageal echocardiography were enrolled...

OBJECTIVE: The Tubridge flow diverter (FD) is a novel device aimed at reconstructing the parent artery and occluding complex aneurysms. Retreatment of recurrent aneurysms using the FD is challenging. We report our initial experience in the repair of aneurysm recurrence with the FD. MATERIALS AND METHODS: A database was reviewed prospectively, and 8 patients with 8 recurrent aneurysms (mean size, 16.7 mm) were identified. Four aneurysms had previously ruptured. The previous aneurysm treatment consisted of coiling in 1 aneurysm and single-stent-assisted coiling in 7 aneurysms...

BACKGROUND: Tortuous or occluded vertebral arteries (VAs) can lead to the endovascular treatment of vertebrobasilar insufficiency being impractical. Bypass surgery is optional, but a craniotomy of the posterior fossa is complicated when physiological vessels must be abandoned. We report 3 cases of refractory vertebrobasilar insufficiencies with different situations of unavailable approaches. Patients were treated by different hybrid operation strategies. CASE DESCRIPTION: Case 1 was of right vertebral artery ostium (VAO) severe stenosis with right V1 segment tortuosity and was treated by right VAO transposition, during which the proximal subclavian artery (SubA) was blocked by a balloon guide catheter...

OBJECTIVE: To compare in the Vertebral Artery Ischaemia Stenting Trial (VIST) the risks and benefits of vertebral angioplasty and stenting with best medical treatment (BMT) alone for symptomatic vertebral artery stenosis. METHODS: VIST was a prospective, randomized, open-blinded endpoint clinical trial performed in 14 hospitals in the United Kingdom. Participants with symptomatic vertebral stenosis ≥50% were randomly assigned (1:1) to vertebral angioplasty/stenting plus BMT or to BMT alone with randomization stratified by site of stenosis (extracranial vs intracranial)...

INTRODUCTION: Vertebrobasilar territory ischemia leads to disabling neurological symptoms and may be caused both by vertebral artery (VA) and subclavian artery (SA) stenosis. The coexisting symptomatic ipsilateral VA and proximal SA stenosis should be considered as a true bifurcation lesion for percutaneous treatment. AIM: To evaluate the safety and efficacy of simultaneous angioplasty of vertebral and subclavian stenosis. MATERIAL AND METHODS: Fifteen patients (age 69...

We present an uncommon case of a 48-year-old female patient with symptomatic presentation of a severe aortic regurgitation with aneurysm of the ascending aorta and progressive dyspnea. Detailed investigation of laboratory tests and imaging identified Takayasu's arteritis (TA) as the underlying etiology. Computed tomography scan revealed complete occlusion of the right carotid artery as well as stenosis at the origins of left subclavian and vertebral arteries. In addition, cardiac magnetic resonance angiogram showed aneurysm at the proximal segment of right subclavian artery...
