Giant cell arteritis (GCA) is the most common form of vasculitis in individuals aged 50 years and over. GCA typically affects large and medium-sized arteries, with a predilection for the extracranial branches of the carotid artery. Patients with GCA usually present with symptoms and signs that are directly related to the artery that is affected, with or without constitutional manifestations. The most dreaded complication of GCA is visual loss, which affects about one in six patients and is typically caused by arteritis of the ophthalmic branches of the internal carotid artery...

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis. It is characterized by multiple xanthogranulomatous masses throughout the body, predominantly in the tibia. One of the characteristic radiological findings of the lesions associated with ECD is a "coated artery," which is often observed in the aorta. Although approximately one-fourth of ECD cases involve the central nervous system (CNS), an intracranial-coated artery has only been reported in four cases. We report a case of ECD that involves the CNS and has the unique appearance of a coated vertebral artery (VA)...

A significant but less recognized cause of ischemic stroke and transient ischemic attack (TIA) is atherosclerosis of the vertebrobasilar system, which accounts for 20% of ischemic strokes. Pathology of the vertebrobasilar system can present significant challenges in determining the course of treatment. Due to the complexity of the vertebrobasilar system, there is slight disagreement about how to approach patients with atherosclerotic pathology of the posterior circulation. Two such approaches are either stenting of the vertebral or basilar artery or aggressive medical management...

BACKGROUND: The cumulative amount of iodinated-contrast-medium necessary for EVAR planning, operative procedure and subsequent follow-up is a threat for the onset of end stage renal disease in patients with pre-operative impaired kidney function. Purpose of this study is to describe a mini-invasive approach aimed to minimize the exposure of these patients to iodinated-contrast-medium and the subsequent risk of renal function worsening. METHODS: From 2012 to 2015, all patients with abdominal aortic aneurysm (AAA) at high-surgical risk and fit for standard endovascular repair (simple aortic-iliac anatomy: proximal and distal neck length ≥15mm, no severe angulation), underwent EVAR through the following "near-zero contrast" approach, if their glomerular filtration rate (GFR) was <30 mL/min: pre-operative planning was performed by non-contrast enhanced computed tomography (CT) and duplex-ultrasound (DU); the origin of renal/hypogastric arteries and aortic bifurcation was evaluated and matched with vertebral bone landmarks and the endograft deployed accordingly, using < 20cc of isotonic iodinate-contrast-medium and contrast-enhancement-DU (CEUS)...

Vertebrobasilar insufficiency leading to posterior circulation infarcts caused by congenital hypoplasia of the bilateral transverse foramina at the C2 level, affecting the caliber and flow of the bilateral distal cervical vertebral arteries in an adult, has not been previously reported. A 41-year-old male presented with episodic dizziness for a period of 1 year prior to consultation. Computed tomography angiography of the head and neck demonstrated congenital hypoplasia of the bilateral C2 transverse foramina, with absence of the vertebral arteries in each of the foramina and collateral reconstitution of diminutive intracranial vertebral artery segments...

A dissecting aneurysm of the vertebral artery in the extracranial portion is a rare pathology. It may either have a symptom-free course or induce a clinical picture of vertebrobasilar insufficiency. To the main methods of surgical treatment belong endovascular techniques and resection of an aneurysm with shunting of the V3 segment of the vertebral artery. Presented in the article is a clinical case report regarding successful surgical management of a dissecting aneurysm of the extracranial portion in a young woman presenting with a clinical course of vertebrobasilar insufficiency and treated by means of ligation of the vertebral artery in the V1 segment and autovenous shunting from the external carotid artery to the V3 segment of the vertebral artery...

The transradial approach (TRA) has become an attractive alternative to the transfemoral approach (TFA) in percutaneous coronary intervention. To date, however, these two approaches have not been systematically compared in various percutaneous peripheral artery interventions (PPAIs). In the present study 258 patients with peripheral artery disease that underwent PPAI via the TRA (n=75) or the TFA (n=183) were analyzed. Clinical factors and outcomes in these two groups were compared. The puncture time was significantly longer (P<0...

BACKGROUND: Spontaneous cervical artery dissection (sCAD) is an important etiology of juvenile stroke. The gold standard for the diagnosis of sCAD is convential angiography. However, magnetic resonance imaging (MRI)/MR angiography (MRA) and computed tomography (CT)/CT angiography (CTA) are frequently used alternatives. New developments such as multislice CT/CTA have enabled routine acquisition of thinner sections with rapid imaging times. The goal of this study was to compare the capability of recent developed 128-slice CT/CTA to MRI/MRA to detect radiologic features of sCAD...

BACKGROUND: To date all researchers conclude that the etiology of Amyotrophic lateral sclerosis (ALS) is not known. On the contrary, since August 2009, we believe that disease is of ischemic origin in the anterior surface of the medulla oblongata. MATERIAL AND METHOD: We present our surgical experience into 45 patients with ALS (bulbar form in 36 cases and spinal form in 9). Preoperative MRI scans revealed microinfarcts in the medulla oblongata and/or cervical cord...

The clinical spectrum of internal carotid artery occlusion ranges from being a completely asymptomatic occlusion to a devastating stroke or death. The prevalence of asymptomatic internal carotid artery occlusion is unknown, particularly for bilateral occlusion. The distal branches of the external carotid artery anastomose with distal branches of the internal carotid artery providing important sources of collateral circulation to the brain. Stenosis of the external carotid artery with ipsilateral/bilateral internal occlusion may result in ischemic sequelae...

We describe a 77-year-old male who had right upper limb ischemic symptoms and history of unsuccessful right subclavian artery angioplasty. According to ultrasound findings, upper limb angiography was performed which confirmed stenosis of the left vertebral and right subclavian arteries. Percutaneous angioplasty and stenting of left vertebral and right subclavian arteries were performed in two separate sessions. Retrograde approach was scheduled for right subclavian artery angioplasty which is challenging due to potential risks to adjacent vertebral artery...

PURPOSE: Reduced flow in the internal carotid artery (ICA) is related to cerebral ischemia. We established a classification of reduced ICA flow through color-coded carotid duplex (CCD) sonography. METHODS: We retrospectively reviewed 25,000 CCD images in sonography laboratory. RESULTS: Reduced ICA flow [flow volume (FV) less than 100 mL/min] was found in 1.2% of all studies, and 270 patients were enrolled. We included 8% patients with lesions proximal to the ICA in Group A, 27% with lesions at the proximal ICA in Group B, 49% with lesions distal to the visible ICA in Group C, and 16% with unknown causes in Group D...

We report a case of bilateral hearing loss caused by decreased vascular flow in the anterior inferior cerebellar artery (AICA) territory. A 74-year-old man who experienced right hearing loss 5 months ago presented with bilateral deafness and right cerebellar ataxia; however, no ischemic lesion was detected in the bilateral AICA area. After stroke treatment, hearing loss was improved. One month later, we obtained blood flow improvement in the left AICA territory on single-photon-emission computed tomography and vertebral artery stenosis on magnetic resonance angiography...

Background Carotid endarterectomy is the established treatment for carotid artery stenosis, and remains the primary surgical option due to its superior outcomes compared to carotid arterial stenting. However, Japanese patients are known to have unfavorable anatomical conditions for carotid endarterectomy, with a relatively higher level of the carotid artery bifurcation than in the Western population. We investigated the outcomes of carotid endarterectomy in our institute and evaluated the procedural quality by comparing patients based on higher or lower lesion levels...

An 83-year-old man with arch aneurysm underwent total arch replacement with frozen elephant trunk and extra-anatomical left subclavian artery bypass. One year later, he felt dizziness associated with head rotation. The hypoplastic left vertebral artery was occluded by a thrombus extending from the left subclavian artery ligation site, and the dynamic stenosis of right vertebral artery by head rotation induced dizziness. He was diagnosed with Bow Hunter syndrome. Vertebral artery hypoplasia represents a possible cause of this rare complication...
