BACKGROUND: Laminoplasty is an established treatment for cervical myelopathy. Multiple variations have emerged, many advocating the use of allograft, but controversy persists. OBJECTIVE: To assess medium-term clinical outcomes in patients who underwent laminoplasty with autograft at our institution. METHODS: Thirty-two consecutive patients (19 male, 13 female, average age 66 yr) from our prospective outcome registry that underwent cervical laminoplasty between 2009 and 2013 were reviewed...

BACKGROUND: Metatropic dysplasia is a rare form of skeletal dysplasia requiring multiple anesthetics for surgical and imaging procedures, most of which are orthopedic procedures. We provide centralized care to patients with skeletal dysplasia at our tertiary care pediatric hospital, and we were able to collect the largest number of metatropic dysplasia patients reported to date. AIM: The aim of this retrospective study was to describe and characterize the anesthetic difficulties in this high-risk population...

PURPOSE: Aim of this study is to compare late degenerative MRI changes in a subset of patients operated on with ACDF to a second subset of patients presenting indication to ACDF but never operated on. METHODS: Patients from both subgroups received surgical indication according to the same criteria. Both subgroups underwent a cervical spine MRI in 2004-2005 and 10 years later in 2015. These MRI scans were retrospectively evaluated with a cervical spine ageing scale...

This paper presents two cases of women who had extensive vaginal adenosis from prenatal DES exposure, extending almost halfway down the vaginal canal. Both women were followed for decades with annual exams and Pap smears until after menopause. Clinical examination in both cases initially showed an absent pars vaginalis of the cervix, vaginal adenosis, and shallowness of the fornices. Several decades of annual exams showed these stigmata of DES exposure gradually disappear as the upper vagina progressively contracted...

We have performed stenting in 11 patients with symptomatic vertebral arterial orifice stenosis refractory to medical treatment or impairment in anterior circulation. Three of the 11 patients experienced asymptomatic severe in-stent restenosis or occlusion. Bare metal stents were used in those three patients, two of whom received revascularization therapy. Development of sufficient cervical collateral channels reconstituting the distal vertebral artery was the common feature in patients with asymptomatic in-stent restenosis...

Background Emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy is a routine procedure. Yet, precise indications and clinical safety in this setting remains controversial. Present data for mechanical thrombectomy include few studies with acute stenting of tandem occlusions. We evaluated the feasibility, safety and clinical outcome of this endovascular treatment in a retrospective analysis of all consecutive cases at a comprehensive stroke centre...

OBJECTIVES: Doppler ultrasound (US) has been widely used to evaluate the cervical venous system of multiple sclerosis (MS) patients according to the hypothesis of chronic cerebrospinal venous insufficiency (CCSVI) with contradictory results. Venous anatomy and pathology can be examined with less operator-dependent magnetic resonance imaging (MRI). DESIGN: To assess the inter-observer agreement in measuring internal jugular vein (IJV) cross-sectional area (CSA) in MR-images and to explore the agreement between US and MRI in the detection of calibres of ≤ 0...

OBJECTIVE Cervical disc arthroplasty (CDA) has been demonstrated to be as safe and effective as anterior cervical discectomy and fusion (ACDF) in the management of 1- and 2-level degenerative disc disease (DDD). However, there has been a lack of data to address the fundamental discrepancy between the two surgeries (CDA vs ACDF), and preservation versus elimination of motion, in the management of cervical myelopathy associated with congenital cervical stenosis (CCS). Although younger patients tend to benefit more from motion preservation, it is uncertain if CCS caused by multilevel DDD can be treated safely with CDA...

BACKGROUND AND AIMS: The severity of obesity is evaluated by visceral-to-subcutaneous fat ratio (VS ratio), which may be useful for predicting atherosclerosis. However, it is unclear how VS ratio affects different types of cerebrovascular lesions. This study was conducted to evaluate the clinical impact of visceral fat accumulation on the cerebrovascular lesions. METHODS: This cross-sectional study included 980 apparently healthy Japanese adults who underwent a health check-up program focused toward atherosclerosis, between 2011 and 2014...

E H Chapel, B A Scansen
Two English bulldogs referred for interventional palliation of severe pulmonary valve stenosis were incidentally diagnosed with unilateral absence of an external jugular vein (left in one case, right in the other) by computed tomography and Doppler ultrasound. The right internal jugular vein also could not be visualized in the dog with absence of the left external jugular vein. Cervical venous anomalies can impact diagnostic or interventional venous catheterization procedures such as balloon pulmonary valvuloplasty...

The aim of this study was to reveal the sensitivity and responsiveness of contact heat evoked potentials (CHEPs) to assess cervical spondylotic myelopathy (CSM). A total of 81 patients with clinically and radiologically confirmed spinal cord compression were reviewed. All patients underwent full clinical examinations with combined recordings of segmental CHEPs and somatosensory evoked potentials (dSSEPs) compared to healthy controls. Cross-sectional area, maximal canal compression, and maximal spinal cord compression were determined based on T2-weighted magnetic resonance images (MRI)...

INTRODUCTION: Cervical arterial dissection (CAD) is a frequent and preventable cause of ischemic stroke in young patients. Several arguments suggest that genetic and developmental disorders could play an important role as part of a multifactorial predisposition of sporadic CAD.We present 2 cases of young patients with CAD in association with cutaneous lesions and nonatherosclerotic multivessel arteriopathy. CASE REPORTS: Our first patient was a 17-year-old white girl with sudden onset of weakness in her right upper limb...

STUDY DESIGN: A retrospective study. OBJECTIVE: To identify preoperative risk factors causing cervical fifth nerve root palsy (C5 palsy) after laminectomy and fusion (LF). SUMMARY OF BACKGROUND DATA: It is well known that postoperative C5 palsy is not rare after cervical surgery. Although there remains controversy, C5 palsy is considered to be more common in patients who had LF than in those who had laminoplasty. However, the reason for the higher incidence of C5 palsy in patients with LF has been poorly understood...

Acute ischemic stroke results from blockage of a cerebral artery or impaired cerebral blood flow due to cervical or intracranial arterial stenosis. Ischemic stroke prevention seeks to minimize the risk of developing impaired cerebral perfusion by controlling vascular and cardiac disease risk factors. Similarly, ischemic stroke treatment aims to restore cerebral blood flow through recanalization of an occluded artery or dilation of a severely narrowed artery that supplies cerebral tissue. Stroke prevention and treatment are increasingly informed by imaging studies, and neurovascular and cerebral perfusion imaging has become essential in in guiding ischemic stroke prevention and treatment...
