INTRODUCTION: The parathyroid gland was first identified in the Indian rhinoceros in 1849 by Sir Richard Owen. We performed a necropsy in an Indian rhinoceros, recapitulating Owen's dissection and display what appear to be the initial identification of the recurrent laryngeal nerve in situ and the anatomy and histology of the largest rhinoceros parathyroid glands yet identified. MATERIALS AND METHODS: Patrick T. Rhino, a 41-year-old Indian rhinoceros was born in 1974...

Background: Traumatic extracranial internal carotid artery (ICA) dissections are uncommon and can be difficult to treat. Thinning of adventitia and dilatation may occur following arterial dissection, thus resulting in a fusiform pseudoaneurysm, which can subsequently cause bleeding, expanding, or pulsatile hematoma. Currently, medical management with anticoagulation remains the first line of treatment and yields good outcomes in 75% of cases with a mortality rate of 3-4%. Endovascular intervention is indicated with failure of medical therapy, progressive enlargement of a traumatic pseudoaneurysm, acute flow-related infarcts due to vessel occlusion, or when anticoagulation is contraindicated due to risk of pseudoaneurysm rupture and hemorrhage...

BACKGROUND: Novel methodologies providing realistic simulation of the neurosurgical operating room environment are currently needed, particularly for highly subspecialized operations with steep learning curves, high-risk profiles, and demands for advanced psychomotor skills. OBJECTIVE: To describe the development of a curriculum for using perfusion-based cadaveric simulation models in a "Mock Operating Room" for neurosurgical procedures. METHODS: At the USC Keck School of Medicine Fresh Tissue Dissection Laboratory between 2012 and 2016, 43 cadaveric specimens underwent cannulation of the femoral or carotid artery and artificial perfusion of the arterial system, and/or cannulation of the intradural cervical spine for intrathecal reconstitution of the cerebrospinal fluid (CSF) system...

The development of formalin-free fixatives is an urgent issue in gross anatomy because of the health hazard and the tissue-hardening actions of formalin. We recently identified the fixative, antimicrobial, and preservative effects of N-vinyl-2-pyrrolidone (NVP), a precursor of the water-soluble macromolecular polymer polyvinylpyrrolidone, in animal experiments. The aim of the present study is to investigate whether NVP solution can be used as an alternative to formalin in human cadaveric dissection. Twelve donated cadavers were infused with NVP via the femoral and common carotid arteries using a peristaltic pump...

AIMS: Aortic dissection (AD) represents one of the most common aortic emergencies with high incidence of morbidity and mortality. Clinical studies have shown that the increased excitability of the sympathetic nerve may be associated with the formation of AD. In this study, we examined the effects of bilateral superior cervical sympathectomy (SCGx) on the progression of β-aminopropionitrile (BAPN)-induced AD in rats. MAIN METHODS: Sprague-Dawley rats were randomly divided into three groups, including BAPN, BAPN+SCGx and control groups...

BACKGROUND: Cervical arterial dissection is a leading cause of stroke in young patients, yet optimal management remains controversial. Existing studies focusing on recurrent stroke were underpowered to demonstrate differences between antithrombotic strategies. Vessel recanalization is a more prevalent outcome and is potentially clinically important. We aimed to assess recanalization rates with anticoagulation compared with antiplatelet therapy. METHODS: We studied a single-center retrospective cohort of patients with extracranial carotid or vertebral artery dissection...

Traumatic vertebral artery dissection (VAD) has been reported in various types of sports and recreation. However, there have been no reports of VAD in rugby players, except for those with cervical spine injuries. We experienced two cases of VAD without cervical spine injuries in high school rugby players. Attention should be paid to protect youth rugby players from VAD.

BACKGROUND: With the popularity of MRI use, vertebrobasilar artery dissection (VBD) has been found more frequently in patients with posterior circulation ischemic stroke (PCS). The relationship between VBD and atherosclerosis is unknown. The present study aimed to prove the hypothesis that PCS with pure VBD (p-VBD) and with VBD and accompanied cervical or cerebral artery atherosclerosis (a-VBD) have distinct manifestations. METHODS: Patients with VBD-related PCS who were prospectively enrolled in the Taipei Veterans General Hospital Stroke Registry between January 1, 2010 and August 31, 2014 were recruited for the present study...

This study demonstrates the radiologic and clinical findings, etiologies and intervention strategy in 8 acute ischemic stroke patients with tandem occlusions. The mean age was 57 and mean NIHSS score was 19. Stent-assisted thrombectomy (SAT) was performed on all of the patients. Additionally, 6 patients underwent carotid artery stenting before SAT. Recanalization with TICI≥2b was attained in 7/8 patients. The 90thday median mRS was 2 and mortality was 1/8. The etiologies of the tandem occlusions were either extracranial high grade ICA stenosis/occlusion or cervical ICA dissection...

A 56-year-old woman was admitted to our hospital because of amaurosis fugax. The carotid angiogram showed irregularly stenotic lesions of the left and right internal carotid arteries (ICAs), suggestive of dissection. Follow-up evaluation was performed by transoral carotid ultrasonography (TOCU) with contrast enhancement (CE), which yielded better vessel lumen and intramural hematoma visualization than color Doppler imaging. CE-TOCU is useful for evaluating ICA dissections that extends to the high cervical portion...

REVIEW
Jennifer J Robertson, Alex Koyfman
Cervical artery dissections (CeAD) include both internal carotid and vertebral artery dissections. They are rare but important causes of stroke, especially in younger patients. CeAD should be considered in patients with strokelike symptoms, a new-onset headache and/or neck pain, and/or other risk factors. Early imaging with computed tomography (CT) or magnetic resonance imaging (MRI) is key to making the diagnosis. Treatment may vary depending on the extent of the dissection, timing of the dissection, and other comorbidities...

BACKGROUND: Spontaneous subclavian artery dissection is a rare etiology. Spontaneous artery dissection causing brain ischemia is rare in all ischemic strokes. However, in young to middle-aged patients with brain ischemia, spontaneous carotid or vertebral artery dissection causing ischemic stroke accounts for 10-25%. CASE REPORT: A 58-year-old man with a history of hypertension presented to the Emergency Department with a sudden onset of left-arm paresthesia and numbness followed by symptoms of vertigo and vomiting...

OBJECTIVES: Spinal dural arteriovenous fistulas (DAVFs) have diverse presentations. Magnetic resonance imaging (MRI) reveals spinal cord swelling in only 45% to 74% of cases. We present an unusual case of a 57-year old man with a craniocervical junction DAVF in which the edema appeared in the thoracolumbar region, skipping the cervical spinal cord. METHODS: A case report and literature review from a tertiary referral center are provided. RESULTS: In our patient, symptoms progressed over 3 months from low back and radicular pain to weakness, saddle anesthesia, and urinary retention...

Recently, time-of-flight (TOF) and gadolinium-enhanced MR angiography (MRA) imaging have been used to demonstrate subacute intramural hematoma in cervical artery dissection and to detect intraplaque haemorrhage. Our aim was to perform an exploratory study to analyse if venous thrombus-related signal changes (potentially showing iso- or hyperintensity) in cerebral venous sinus thrombosis (CVST) could be observed on 3D-TOF MRA imaging. We analysed retrospectively MRIs of CVST patients in whom both contrast-enhanced MR venography (CEMRV) and 3D-TOF sequences were performed in the acute/subacute phase (i...

BACKGROUND: Extended-field chemoradiation therapy is usually performed in patients with locally advanced cervical cancer (LACC) and paraaortic (PA) node metastases. Considering the very low rate of skip metastases above inferior mesenteric artery, ilio-inframesenteric paraaortic lymph node dissection (IM-PALND) seems to be an adequate pattern of PALND. Our objective was to assess the accuracy of this management to determine PA nodal status in comparison with infrarenal paraaortic lymphadenectomy (IR-PALND) in case of squamous or glandular cervical cancer...

Introduction Pathophysiology of cervical artery dissection is complex and poorly understood. In addition to well-known causative and predisposing factors, including major trauma and monogenic connective tissue disorders, morphological characteristics of the styloid process have been recently recognized as a possible risk factor for cervical internal carotid artery dissection. Aims To study the association of the anatomical characteristics of styloid process with internal carotid artery dissection. Methods Retrospective, multicenter, case-control study of patients with internal carotid artery dissection and age- and sex-matched controls...

OBJECTIVE: Spontaneous cervical artery dissection (CAD) is a cerebrovascular disease typically considered to affect the young population. Literature reports cases in the elderly only as incidental findings, making the diagnosis unlikely in older patients. Incidence and pathogeny in this specific population remain to be assessed. METHODS: We reviewed patients aged over 70 years admitted for spontaneous CAD in the Stroke Unit of the University Hospital of Nancy (northeastern France) over a period of 12 years as well as all reported cases in literature...
