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...

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...

PURPOSE: Main symptom of mucopolysaccharidosis type IVa (MPS IVa) is progressive systemic skeletal dysplasia. This is routinely monitored by cerebral and spinal MRI. The vascular system is generally not in the primary focus of interest. In our population of MPS IVa patients we observed vessel shape alterations of the vertebrobasilar arteries, which has not been described before. MATERIAL AND METHODS: MRI-datasets of 26 patients with MPS IVa acquired between 2008 and 2015 were eligible for retrospective analysis of the vertebrobasilar arteries...

Lateral medullary infarction rarely leads to central hypoventilation syndrome (CHS). CHS is a life-threatening disorder characterized by hypoventilation during sleep. We report the first case of CHS as a complication of lateral medullary infarction after endovascular treatment. A 65-year-old man presented twice with severe headache. Computed tomography revealed subarachnoid hemorrhage and cerebral angiography showed a right vertebral dissecting aneurysm involving the posterior inferior cerebellar artery. After emergent endovascular patent artery occlusion, he developed Wallenberg syndrome and experienced apnea and a conscious disturbance episode due to CHS on postoperative days 6 and 16...

A 70-year-old male sustained a Jefferson burst fracture with unilateral vertebral artery dissection and occlusion by displaced fragments. We performed reduction and posterior C1-ring osteosynthesis. We present a description of the intraoperative manual assessment of atlantoaxial stability. The vertebral artery was found with a good anterograde flow posteroperatively, and MRA showed reperfusion of the vessel. The patient was free of pain with preserved C1-C2 rotation after 6 weeks. Function-preserving posterior C1-ring osteosynthesis after reduction in a displaced Jefferson burst fracture complicated by vertebral artery dissection and occlusion may restore blood flow...

Dissections of extracranial arteries are estimated to account for only 2% of all ischemic strokes but for approximately 20% of strokes in patients younger than 45 years old. Most dissections of extracranial arteries involve some trauma stretch, mechanical stress, or connective tissue abnormalities. In the absence of these disorders, determining the etiology of recurrent extracranial dissections is quite challenging because the underlying nature of these cases is poorly understood. We report the case of a 44-year-old female with recurrent dissections of the vertebral and carotid arteries associated with a heterozygous mutation p...

Objective: To summarize the classifications and optimize endovascular treatment of the dissecting aneurysms of the vertebral artery (DAVA). Methods: The clinical information of 39 cases of DAVA treated with endovascular methods in our department between January 2007 and September 2016 were analyzed retrospectively.According to the location of the aneurysm in relation to the posterior inferior cerebellar artery (PICA), the aneurysms were classified into three types: type pre-PICA, located proximally to the PICA; type in-PICA, located at the PICA origin; and type post-PICA located distally to the PICA...

BACKGROUND AND PURPOSE: Small studies have suggested that Ehlers-Danlos syndrome (EDS) is associated with a number of cerebrovascular complications. We sought to determine whether a clinical diagnosis of EDS is associated with a higher prevalence of cerebrovascular diseases than the general population by performing a case-control study of hospitalized patients in the Nationwide Inpatient Sample (NIS). METHODS: Using the 2000-2012 NIS, we performed a case-control study matching cases of EDS to controls without such a diagnosis...

BACKGROUND: Although an asymptomatic spinal dural arteriovenous fistula (SDAVF) can sometimes be incidentally detected on magnetic resonance imaging (MRI), there are no previous reports showing the development of an SDAVF on MRI or magnetic resonance angiography (MRA). CASE DESCRIPTION: A 64-year old man with unruptured vertebral artery dissection (VAD) developed a subarachnoid hemorrhage (SAH) during regular follow-up. Emergent endovascular coil internal trapping for the VAD was performed; however, angiography after the endovascular treatment showed a lower cervical SDAVF...

Ruptured intracranial vertebral artery dissection is a cause of non-traumatic subarachnoid hemorrhage. Urgent intervention should be considered to prevent fatal rebleeding. Endovascular parent artery occlusion, which is the initial treatment of choice, is not suitable for patients with a hypoplastic or occlusive contralateral vertebral artery. We report a case of ruptured vertebral artery dissection, which was successfully treated with double overlapping stent-assisted coiling.

BACKGROUND AND PURPOSE: Traumatic brain injury (TBI) leads to nearly 300 000 annual US hospitalizations and increased lifetime risk of acute ischemic stroke (AIS). Occurrence of AIS immediately after TBI has not been well characterized. We evaluated AIS acutely after TBI and its impact on outcome. METHODS: A prospective database of moderate to severe TBI survivors, admitted to inpatient rehabilitation at 22 Traumatic Brain Injury Model Systems centers and their referring acute-care hospitals, was analyzed...

BACKGROUND: Dissecting aneurysms of the basilar artery (BA) are rare lesions and the management of them has been controversial and challenging. The treatment becomes much more difficult when the patient has a disorder such as aortitis syndrome, which makes cerebral arteries occluded and tortuous. The authors describe a case of a ruptured BA dissecting aneurysm associated with aortitis syndrome, successfully treated with hybrid neurovascular surgery. CASE DESCRIPTION: A 64-year-old woman with a medical history of aortitis syndrome developed a severe headache and was diagnosed with a subarachnoid hemorrhage from a BA dissecting aneurysm...

A dissecting aneurysm of the vertebral artery in the extracranial portion is a rare pathology. It may either have a symptom-free course or induce a clinical picture of vertebrobasilar insufficiency. To the main methods of surgical treatment belong endovascular techniques and resection of an aneurysm with shunting of the V3 segment of the vertebral artery. Presented in the article is a clinical case report regarding successful surgical management of a dissecting aneurysm of the extracranial portion in a young woman presenting with a clinical course of vertebrobasilar insufficiency and treated by means of ligation of the vertebral artery in the V1 segment and autovenous shunting from the external carotid artery to the V3 segment of the vertebral artery...

BACKGROUND: The V2 segment of the vertebral artery (VA) typically runs through the transverse foramen of C2-C6. V2 injury may occur during anterior approaches to the cervical spine and can cause significant morbidity. We aimed to describe landmarks and microsurgical V2 repair techniques through the standard anterolateral cervical discectomy approach. METHODS: Five silicone-injected cadaveric heads (necks-C7) were dissected bilaterally. An anterolateral approach with C3-4, C4-5, and C5-6 discectomies and an ipsilateral VA injury were simulated...

BACKGROUND: Spontaneous cervical artery dissection (sCAD) is an important etiology of juvenile stroke. The gold standard for the diagnosis of sCAD is convential angiography. However, magnetic resonance imaging (MRI)/MR angiography (MRA) and computed tomography (CT)/CT angiography (CTA) are frequently used alternatives. New developments such as multislice CT/CTA have enabled routine acquisition of thinner sections with rapid imaging times. The goal of this study was to compare the capability of recent developed 128-slice CT/CTA to MRI/MRA to detect radiologic features of sCAD...

A patient presented with fulminant pulmonary oedema and required acute intubation and ventilation. There was no history of a prior cardiac disorder. As he was weaned from sedation, following stabilisation of his pulmonary status, neurological signs suggestive of brainstem dysfunction became apparent. Investigations showed infarcts in the posterior cerebral circulation secondary to a vertebral artery dissection. Neurogenic pulmonary oedema needs to be considered in any patient with fulminant pulmonary oedema without overt evidence or history of cardiac disease...
