Surgical nuances on the treatment of giant dumbbell cervical spine schwannomas: description of a challenging case and review of the literature
2016
We report a case of a giant intra and extradural cervical schwannoma in a patient affected by a severe myelo-radiculopathy. Clinical features, diagnosis and the issues concerning the surgical management of this benign tumor are discussed. We also review similar cases previously reported in the literature. A 50-year old caucasian woman was complaining of a 1 year of neck pain and worsening motor impairment in all four limbs causing the inability to walk. Neuroradiological assessment revealed a suspected schwannoma involving the nerve roots from C3 to C5, compressing and deviating the spinal cord. The vertebral artery was also encased within the lesion, but still patent. A posterior cervical …
Vertebrobasilar junction giant aneurysm: Lessons learned from a neurosurgical audit and anatomical investigation.
2015
The treatment of vascular lesions of the vertebrobasilar junction (VBJ) remains a challenging task in the neurosurgical practice and the gold standard therapy is still under debate. In this article, the authors report a detailed postmortem study of a VBJ giant aneurysm (GA) previously endovascularly treated. Although the decision-making process for the vast majority of neurosurgical treatment can nowadays be accurately carried out during the preoperative planning (i.e., with the aid of neuroimaging fusion protocols, neuronavigation platforms, etc.) meant to maximize the anatomical understanding of the lesions and minimize possible intraprocedural challenges, this postmortem study represents…

Posterior Approach to Axis Instability
2016
Many pathologies can cause instability of the cranio-vertebral junction (CVJ). Among the most common diseases must be considered thraumatisms, neoplasms, inflammation, but also congenital malformations. Instability of the CVJ is a potentially life-threatening condition and improper treatment can lead to severe neurological deficits as well as continuous, excruciating pain in the neck. Conservative treatments are often disappointing and surgery must always be taken in consideration when approaching instability of the CVJ, being in many cases the only therapy that can provide satisfactory results.
Arteriovenous fistula of the vertebral artery in a female infant with hypotonia and cephalocorporal disproportion
2010
Background: Congenital arteriovenous fistulas are exceptional in childhood and imply a therapeutic challenge. Case report: A 9-month-old female infant was studied for cephalocorporal disproportion, hypotonia, progressive muscular atrophy and hyperreflexia. Computed tomography of the brain and electroencephalography were normal. Electromyographic patterns suggested proximal myopathic involvement. A continuous murmur with systolic reinforcement was audible in the neck. Angioresonance detected intracranial aneurysmal dilatations behind the bulbo-medullary junction and cerebral panangiography evidenced a direct vertebrovertebral fistula with extra- and intra-cranial varices and extreme medulla…
Optimal interventional treatment in a patient with occlusion of the brachiocephalic trunk and left subclavian artery with “double” steal syndrome
2015
Subclavian steal syndrome, which comprises reversal of flow in the ipsilateral vertebral artery with stenosis or occlusion of the subclavian artery (SA) or brachiocephalic trunk (BCT), was first described by Contorni in 1960 [1]. This clinical syndrome manifests with the signs and symptoms of vertebrobasilar insufficiency, but can also be asymptomatic. This paper describes a step-by-step technique of complex endovascular treatment for a double steal syndrome caused by occlusions of the BCT and the left SA, associated with stenosis of the left internal carotid artery (ICA) and reversed flow in the left external carotid artery (ECA).
Dolichoectasia of the vertebrobasilar complex causing neural compression
2014
Dear Editor, We have read with great interest the paper of Yuh et al.[4] reporting a case of symptomatic hydrocephalus due to vertebrobasilar dolichoectasia (VBD) compressing the brainstem. Ectatic or pathologically enlarged vertebrobasilar arteries have been reported with increasing frequency and associated with several clinical syndromes. These include an assortment of cranial nerve syndromes, transient or permanent motor deficit, cerebellar dysfunction, central sleep apnea, ischemic stroke, hypertension, and hydrocephalus as reported in the paper by Yuh et al.[4] Others and we have also described pyramidal tract signs and cranial nerve nucleus dysfunction caused by vascular compression o…
Anatomy of the cervical spine
2015
The vertebral column, or spine, consisting of a coordinated series of 33-34 vertebrae separated from each other by intervertebral disks, is divided in five segments or sections: cervical, dorsal, lumbar, sacral and coccygeal [1-7]. Not available
