BACKGROUND AND IMPORTANCE: Stent-assisted coil embolization has been established as a treatment option for wide-necked or complex aneurysms. However, concerns have been raised about the incidence of thromboembolic complications, which is higher for coil embolization without stent assistance. Long-term antiplatelet therapy is necessary to prevent acute or delayed ischemic events potentially associated with incomplete stent apposition after treatment with stent-assisted coil embolization...

Sirenomelia, also known as "mermaid malformation/syndrome," is a rare, serious congenital anomaly characterized by variable degrees of fusion of the lower limbs and associated with severe malformations of vertebral, genitourinary, cardiovascular system and single umbilical artery. The first pregnancy of a 25-year-old woman resulted in one twin born by Cesarian section at 32 weeks' gestation, who was referred to our hospital with cyanosis, a congenital anomaly and respiratory distress. On physical examination, there was no urogenital region and anal fissure and gender was indeterminate...

A 78-year-old Caucasian man with significant vascular disease reported sudden onset of worsened vision during a routine wound-care appointment for non-healing necrotic leg ulcers. He described painless blurring of vision with grey scotomas in his RE, his only well-seeing eye, following trauma to the LE as a child. He presented with retinal ischemia, a cotton-wool spot and optic nerve swelling. Temporal artery biopsy showed myxoid degeneration and extensive calcium deposition which also was shown on imaging throughout his carotid and vertebral arterial system, the clinical picture of calciphylaxis...

BACKGROUND: For some posterior inferior cerebellar artery (PICA) aneurysms, there is no constructive endovascular or direct surgical clipping option. Intracranial bypass is an alternative to a deconstructive technique. OBJECTIVE: To evaluate the clinical features, surgical techniques, and outcome of PICA aneurysms treated with bypass and obliteration of the diseased segment. METHODS: Retrospective review of PICA aneurysms treated via intracranial bypass was performed...

BACKGROUND: Fusiform intracranial aneurysms are challenging due to the circumferential nature of the disease. Endovascular parent vessel sacrifice with coils may be a treatment option, but typically requires a long vessel segment to induce complete cessation of flow. OBJECTIVE:   We evaluate early clinical experience with the intracranial use of the microvascular plug (MVP; Medtronic, Dublin, Ireland) device and to compare to previous coil-only techniques for vertebral artery sacrifice for fusiform vertebral aneurysm...

INTRODUCTION: The stabilization of an atlantoaxial (C1-C2) instability is demanding due to a complex atlantoaxial anatomy with proximity to the spinal cord, a variable run of the vertebral artery (VA) and narrow C2 pedicles. We perfomed the Goel & Harms fusion in combination with an intraoperative 3D imaging to ensure correct screw placement in the C2 pedicle. We hypothesized, that narrow C2 pedicles lead to a higher malposition rate of screws by perforation of the pedicle wall. The purpose of this study was to describe a certain pedicle size, under which the perforation rate rises...

BACKGROUND AND OBJECTIVE: Bleeding into the retropharyngeal space is a potential complication in stellate ganglion block (SGB). Retropharyngeal hematoma formation is considered to be due to damage of small arteries in the region, although only scanty details of the region are available. The aim of this study was to map the risk blood vessels in the retropharyngeal space to avoid accidental damage during SGB. METHODS: Contrast-enhanced 3-dimensional computed tomography images performed on 80 patients were reanalyzed retrospectively to construct detailed map of cervical blood vessels that are prone to damage and bleeding during SGB...

Little literature is available on hemiparesis caused by vascular medullary compression, which may occur as a result of dolichoectasia of the vertebrobasilar arterial system. In this paper, we report a case of vertebral artery compression of the medulla oblongata in a 67-year old woman. The patient was hypertensive and developed hemiparesis and intermittent spasms for five years, which became worsened for one year. Cranial nerve MRI showed compression of the medulla oblongata by the left vertebral artery. Motor evoked potential (MEP) examination showed abnormal conduction of MEPs of bilateral toe abductors...

INTRODUCTION: Complex skull base approaches are frequently used to treat intracranial vertebral artery (VA) and proximal posterior inferior cerebellar artery (PICA) aneurysms. These complex procedures are associated with higher risk of neurovascular injury. Hence, a less invasive surgical approach is needed to improve treatment's efficacy and safety. MATERIAL AND METHODS: A retrospective analysis was conducted on clinical and radiological data from surgeries where simple lateral suboccipital and "lateral enough" approaches were used to clip VA aneurysms in the Department of Neurosurgery at Helsinki University Central Hospital from 2000 - 2009...

OBJECTIVES: To evaluate the value of left vertebral artery filter protection in addition to the current filter-based embolic protection technology to achieve complete cerebral protection during TAVR. BACKGROUND: The occurrence of cerebrovascular events after transcatheter aortic valve replacement (TAVR) has fueled concern for its potential application in younger patients with longer life expectancy. Transcatheter cerebral embolic protection (TCEP) devices may limit periprocedural cerebrovascular events by preventing macro and micro-embolization to the brain...

BACKGROUND: Vascular compression of the medullary pyramid resulting in neurological compromise is rare, therefore, diagnosis is difficult and ultimately delayed. Most patients present with a combination of cranial nerve, autonomic, and/or motor and sensory dysfunction. Presentation with a single sign such as hemiparesis is rare. The low number of cases reported has made it impossible to define a standard treatment for this unusual disorder. CASE DESCRIPTION: Here, we present a patient with a progressive left hemiparesis due to compression of the upper medulla by the vertebral artery, which was treated with repositioning of the artery using a sling...

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: Chordomas arise from remnants of the notocord and occur throughout the neuroaxis. En bloc resection of chordomas can prove especially challenging in the upper cervical spine secondary to the unique structural anatomy and intimate relationship to the vertebral arteries and spinal cord. CASE DESCRIPTION: We describe the resection of a C2-3 chordoma in a 55 year old female in two stage fashion with preservation of the vertebral arteries. First a posterior instrumented fusion and removal of the posterior elements was performed, followed by an anterior transmandibular en bloc resection with cage reconstruction with kick-plate support achievable with off-the-shelf products...

Giant thrombosed aneurysms of the vertebral artery (VA) are difficult to treat. Moreover, marked tortuosity of the parent VA complicates determination of the surgical approach. We report the case of a 71-year-old male patient who presented with gait disturbance. Magnetic resonance imaging revealed a giant thrombosed aneurysm of approximately 4cm in diameter located in the ventral region and to the right of the medulla oblongata. Computed tomography angiography showed that the right VA had extreme tortuosity, and that the VA union was in contact with the left 7th and 8th cranial nerves...
