We describe a case of reproducible asystole during endovascular treatment of a posterior fossa dural arteriovenous fistula. Catheterisation of the posterior meningeal artery, a branch of the vertebral artery in this patient, followed by dimethyl sulfoxide injection prior to Onyx administration resulted in two episodes of asystole.To the best of our knowledge, this is the first reported case of asystole occurring during endovascular intervention in the posterior meningeal artery. This may represent a previously undescribed variant of the trigemino-cardiac reflex (TGCR) caused by chemical stimulation of small areas of trigeminally innervated posterior fossa dura...

BACKGROUND CONTEXT: Surgical treatment for unstable atlas fractures has evolved in recent decades from C1-C2 or C0-C2 fusion to motion-preservation techniques of open reduction and internal fixation (ORIF). However, regardless of transoral or posterior approach, the reduction is still not satisfactory. PURPOSE: The article describes and evaluates a new technique for treating the unstable atlas fractures by using a monoaxial screw-rod system. STUDY DESIGN: This is a retrospective study PATIENT SAMPLE: The sample includes adult patients with unstable C1 fractures treated with a posterior monoaxial screw-rod system...

BACKGROUND: Landmark-guided internal jugular vein cannulation is difficult for pediatric patients but useful, especially when ultrasound equipment is unavailable. Therefore, it is important to define the adjacent anatomic characteristics of the pediatric internal jugular vein. METHODS: In 210 children the course of the internal jugular vein, and common carotid and vertebral arteries was measured from the level of the cricoid cartilage to the supraclavicular area using ultrasound...

AIM: The purpose of this retrospective observational study was to investigate the anatomical characteristics of the vertebral artery in pediatric patients using computed tomography images. METHODS: We evaluated anatomical characteristics of the right and left vertebral artery at the cricoid level and at a lower level, which was mid-level between the cricoid cartilage and the origin of vertebral artery from the subclavian artery. At each level, the cross-sectional areas of the vertebral artery and internal jugular vein, the relative size of vertebral artery to internal jugular vein, the minimum distance between them, and the extent of overlap between them were investigated...

Mechanosensitivity is a fundamental physiological capacity, which pertains to all life forms. Progress has been made with regard to understanding mechanosensitivity in bacteria, flies, and worms. In vertebrates, however, the molecular identity of mechanotransducers in somatic and neuronal cells has only started to appear. The Piezo family of mechanogated ion channels marks a pivotal milestone in understanding mechanosensitivity. Piezo1 and Piezo2 have now been shown to participate in a number of processes, ranging from arterial modeling to sensing muscle stretch...

REVIEW
Anna Klaus, Catherine Robin
Hematopoietic stem cells (HSCs) are at the origin of adult hematopoiesis, providing an organism with all blood cell types needed throughout life. During embryonic development a first wave of hematopoiesis (independent of HSCs) allows the survival and growth of the embryo until birth. A second wave of hematopoiesis that will last into adulthood depends on the production of HSCs that begins at mid-gestation in large arteries such as the aorta. HSC production occurs through a hemogenic endothelial to hematopoietic transition (EHT) process and the formation of hematopoietic clusters in most vertebrate species...

Dissections of the cervical arteries account for approximately 15-20 % of all strokes in young patients. Clinically they present with laterocervical and/or hemicranial pain associated to a Horner syndrome in case of carotid dissection and a posterior cervical pain associated to headache in the occipital area in case of vertebral dissection. A multifactorial origin is often suggested, resulting from the combination of a weakness of the arterial wall, hereditary or not, of environmental factors such minor trauma or a previous infection and also of the presence of a certain number of vascular risk factors such as high blood pressure or migraines...

BACKGROUND: Bilateral vertebral artery dissection (VAD) may result in subarachnoid hemorrhage (SAH). However, a variety of factors contribute to the difficulties with treating SAH. We report a case of bilateral VAD with SAH, as well as a literature review. CASE DESCRIPTION: A 32-year-old woman developed headache. Computed tomography (CT) demonstrated diffuse SAH, and 3-dimensional CT indicated bilateral VAD. Her left vertebral artery was severely stenosed and the basilar artery was retrogradely flowed via the posterior communicating artery...

Teleosts comprise 95% of fish species, and almost half of all vertebrate species, and represent one of the most successful adaptive radiation events among vertebrates. This is thought to be in part due to their unique oxygen (O2) transport system. In salmonids, recent in vitro and in vivo studies indicate that hemoglobin-oxygen (Hb-O2) unloading to tissues may be doubled or even tripled under some conditions without changes in perfusion. This is accomplished through the short-circuiting of red blood cell (RBC) pH regulation resulting in a large arterial-venous pH difference within the RBC and induced reduction in Hb-O2 affinity...

False aneurysms of the extracranial vertebral artery (FAVA) are rare because of the path of the artery at the level of the transverse holes. They can be secondary to penetrating cervical trauma, spontaneous in the course of an angiopathy such as Ehlers-Danlos syndrome, or iatrogenic. We report the case of a 31-year-old woman who presented a syndrome of Claude Bernard-Horner related to a spontaneous FAVA. The angioscanner confirmed the diagnosis and the patient underwent successful surgical treatment of the false aneurysm with ligature of the vertebral artery...

There are no standard guidelines for treatment of spinal cord ischemia due to how rare it is and the diverse etiology and presentations involved. In addition, to date, there have been no large clinical trials examining ideal pharmacologic treatment options for spinal cord infarct. In our practice, we rely on hemodynamic augmentation initiated as soon as possible. Otherwise, treatment is usually geared towards the etiology of spinal cord ischemia. For instance, spinal cord ischemia occurring after aortic aneurysmal repair may improve with CSF drainage through a lumbar catheter in the periprocedural setting...

Alagille syndrome (AGS) is a complex multisystem disorder that involves mainly the liver, heart, eyes, face, and skeleton. The main associated clinical features are chronic cholestasis due to a paucity of intrahepatic bile ducts, congenital heart disease primarily affecting pulmonary arteries, vertebral abnormalities, ocular embryotoxon, and peculiar facies. The manifestations generally become evident at a pediatric age. AGS is caused by defects in the Notch signaling pathway due to mutations in JAG1 or NOTCH2...

Giant cell arteritis (GCA) is the most common form of vasculitis in individuals aged 50 years and over. GCA typically affects large and medium-sized arteries, with a predilection for the extracranial branches of the carotid artery. Patients with GCA usually present with symptoms and signs that are directly related to the artery that is affected, with or without constitutional manifestations. The most dreaded complication of GCA is visual loss, which affects about one in six patients and is typically caused by arteritis of the ophthalmic branches of the internal carotid artery...
