Cervical Artery Tortuosity Is Associated With Dissection Occurrence and Late Recurrence: A Nested Case-Control Study.

Background: The pathogenesis of spontaneous cervical artery dissection remains unclear, and no established predictors of recurrence exist. Our goal was to investigate the potential association between cervical artery tortuosity, a characteristic of patients with connective tissue disorder, and spontaneous cervical artery dissection.

Methods: The ReSect study (Risk Factors for Recurrent Cervical Artery Dissection) is an observational study that invited all spontaneous cervical artery dissection patients treated at the Innsbruck University Hospital between 1996 and 2018 for clinical and radiological follow-up.

Treatment of unruptured intracranial vertebral artery dissection aneurysms with Flow Diverter compared with conventional stent-assisted coiling-a single-center study.

Aim: Flow diverters (FDs) are being increasingly used off-label for treatment of intracranial vertebral artery dissection aneurysms (IVADAs). However, the safety and efficacy of FDs for unruptured IVADAs remain unclear. This study was performed to investigate whether FDs-alone are safer and more effective than conventional stent-asisted coiling.

Preoperative and Postoperative Arterial Adaptation in Patients with Acute Aortic Dissection.

Spinal cord ischemia is one of the most serious complications after an aortic repair. To date, there is no evidence for arterial changes during an aortic dissection or for the observation of such arteries after an aortic repair. The aim of this study was to compare spinal-cord-supplying arteries in patients with an acute aortic dissection, preoperatively and postoperatively, with patients without an acute aortic dissection.

[Total Arch Replacement and Open Stent Grafting for Stanford Type A Acute Aortic Dissection with an Aberrant Left Vertebral Artery:Report of a Case].

A 61-year-old man was referred to our hospital for Stanford type A acute aortic dissection and an emergency operation was planned. In this case, the aberrant left vertebral artery originated directly from the aortic arch. Total arch replacement at the level between the left carotid artery and left aberrant vertebral artery was performed and an open stent graft was deployed in the true lumen of the descending aorta to obtain better distal aortic remodeling.

Epidemiology of traumatic cervical artery dissections.

Introduction: Unlike spontaneous cervical artery dissection (CeAD), the incidence of CeAD after a major trauma is not well characterized. This population-based observational study investigates the epidemiology and natural history of traumatic cervical artery dissection (CeADs) using data from the Rochester Epidemiology Project (REP) in Olmsted County, USA.

Methods: The REP system database has a high likelihood of complete case ascertainment and comparable demographics (age, sex) to the US population.

Serious adverse events associated with conservative physical procedures directed towards the cervical spine: A systematic review.

Background: Previous reviews on serious adverse events (SAEs) following physical interventions involving the neck have focused on vascular SAEs or those related to cervical manipulation.

Objective: To review the evidence for all serious adverse events associated with any physical cervical procedures and describe SAE characteristics.

Methods: Searches were conducted in PubMed, EMBASE, CINAHL, Scopus, Cochrane, Web of Science and Index to Chiropractic Literature from inception to May 2023 for studies reporting characteristics of SAE following any neck intervention and patient demographics.

Babinski-Nageotte syndrome after vertebral artery dissection and foramen arcuale.

Vertebrobasilar ischaemia happens for a myriad of reasons. Among the rarest is the existence of a foramen arcuale (FA). This condition results from the ossification of the lateral edge of the posterior atlantooccipital membrane, closing, completely or partially, the top of this groove, turning it into a foramen or a channel.

Fenestration of the vertebral artery in a polytrauma patient: A vascular anatomical variant.

Fenestration of the vertebral artery is a rare vascular anatomical variant that can mimic a dissection if discovered during cervical trauma. It is important to diagnose it through computed tomography (CT) angiography or magnetic resonance (MR) angiography in order to best guide the patient's management.

Differential outcomes and treatment in non-traumatic carotid versus vertebral cervical artery dissection: A national inpatient sample study.

Introduction: Cervical artery dissection (CAD) involves the carotid or vertebral artery. However, limited studies have compared their clinical features and outcomes.

Methods: We examined non-traumatic CAD patients from the National Inpatient Sample (2005-2019).

Endovascular treatment for posterior inferior cerebellar artery aneurysm with vertebral artery stenosis: The critical role of diagnosing osteophyte compression.

Background: Vertebral artery (VA) stenosis can be caused by several factors, including arteriosclerosis, arterial dissection, and mechanical compression. Symptomatic vertebrobasilar insufficiency caused by VA stenosis due to mechanical compression associated with head rotation is well-known as Bow Hunter's syndrome. However, an accurate diagnosis of asymptomatic osteophyte compression-induced nonrotational VA stenosis is difficult.

Dynamic changes of abnormal muscle response during decompression procedures in double compression-type hemifacial spasm.

Background: Hemifacial spasm (HFS) is a neurovascular movement caused by vascular compression of the facial nerve in its root exit zone (REZ). Cases of HFS caused by double compression (DC) in both REZ and the cisternal portion (CP) have been sporadically reported. The nature of DC-type HFS is still not fully understood.

How I do it: far-lateral approach using a linear incision.

Background: The far-lateral approach, frequently employed by skull base surgeons, targets lesions in the ventrolateral region of the craniovertebral junction (CVJ). Although various incisions can be utilized, the linear incision is notably less invasive and more efficient. Despite its advantages, the literature lacks a comprehensive description of the technical steps involved in this approach.

Natural course of the acute unruptured intracranial vertebral artery dissections which show pearl-and-string sign.

Introduction: Ruptured vertebral artery dissections frequently exhibit pearl-and-string signs, a characteristic also observed in many unruptured dissections. This study examines the natural course of 50 unruptured acute vertebral artery dissections presenting with pearl-and-string signs and compares them to 10 ruptured dissections of the same morphological pattern.

Methods: We reviewed 633 radiology reports of head and neck imaging studies that included the keyword 'dissection'.
