Evaluation of Rotational Vertebral Artery Occlusion Using Ultrasound Facilitates the Detection of Arterial Dissection in the Atlas Loop
CONCLUSIONFor posterior circulation stroke patients, adding submaximal head rotation to the cervical ultrasound examination facilitated the detection of VAD in the atlas loop.

CT versus MR Techniques in the Detection of Cervical Artery Dissection
CONCLUSIONSCT/CTA is a reliable and better available alternative to MRI/MRA for diagnosis of sCAD. CT/CTA should be used to complement MRI/MRA in cases where MRI/MRA suggests occlusion.

Endovascular repair of an acute symptomatic carotid artery dissection through the false dissecting carotid lumen.
Authors: Befera N, Griffin AS, Hauck EF Abstract A 48-year-old woman presented with an acute ischemic stroke (National Institutes of Health Stroke Scale (NIHSS) 21) six hours after symptom onset. Workup revealed a left cervical internal carotid artery (ICA) occlusive dissection, which was emergently reconstructed with a flow-diverting stent. A routine Duplex scan one hour later suggested reocclusion of the ICA, confirmed by angiography. The true lumen of the ICA could not be accessed and therefore the "false lumen" of the ICA dissection was entered proximally. The true lumen and ultimately the flow-diverting stent ...

Thunderclap headache: Diagnostic considerations and neuroimaging features
Thunderclap headache (TCH) is an acute and severe headache that has maximum intensity at onset; TCH can be primary or secondary. Primary TCH is diagnosed when no underlying cause is discovered; however, imaging is crucial in distinguishing secondary causes, which are wide-ranging. The radiologist should be aware of the list of potential diagnoses. Subarachnoid haemorrhage (SAH) is the most common cause of secondary TCH. Aneurysmal SAH accounts for the majority of cases, although other causes should also be considered and these include perimesencephalic haemorrhage, arteriovenous malformations, and dural arteriovenous fistu...

Safety of Unilateral Endovascular Occlusion of the Cervical Segment of the Vertebral Artery without Antecedent Balloon Test Occlusion EDITOR'S CHOICE
CONCLUSIONS: In this series, endovascular occlusion of a cervical segment of 1 vertebral artery was safely performed without antecedent balloon test occlusion. As long as both vertebral arteries were patent and converged at the vertebrobasilar junction, there was anatomic potential for retrograde filling of the distal intracranial vertebral artery to the level of the posterior inferior cerebellar artery origin, and there was no major vascular supply to the spinal cord arising from the target segment of the affected vessel. Dominant and nondominant vertebral arteries were safely occluded, and no infarcts were attributed to the treatment.

Intracranial and Extracranial Neurovascular Manifestations of Takayasu Arteritis ADULT BRAIN
CONCLUSIONS: Intracranial vascular abnormalities in patients with Takayasu arteritis presenting with neurologic symptoms are not rare, with cerebral vasculitis seen in 7.8% of patients, and stroke secondary to large-vessel occlusion, in 3.9% of patients. Cervical vascular manifestations of Takayasu arteritis were present in most patients in our study.

Emergent cervical internal carotid artery angioplasty before endovascular thrombectomy for acute ischemic stroke: a report of clinical and imaging outcome
A case of tandem occlusion consisting of right internal carotid artery (ICA) origin dissection and middle cerebral artery (MCA) thromoboembolism is reported. A 45  year-old male with right-sided neurological symptoms of emergent large vessel occlusion was treated with same-session angioplasty and mechanical thrombectomy of the respective lesions. The complete neurological recovery and radiological investigations are chronicled herein, and a review of the st ate of tandem occlusion management is discussed.

Standard Diffusion-Weighted Imaging in the Brain Can Detect Cervical Internal Carotid Artery Dissections EXTRACRANIAL VASCULAR
CONCLUSIONS: In our cohort, a standard DWI sequence performed on the brain at the acute phase of a stroke or for a clinical suspicion of dissection detected nearly 90% of cervical ICA dissections.

Ultrasound Criteria for Diagnosing Spontaneous Cervical Artery Dissections
This article describes the diagnostic criteria and typical findings of spontaneous dissection, in which no dissecting membrane is to be expected as in aortic dissection. Traumatic dissections following blunt or penetrating injuries also present with different findings. Examiners should be aware of possible differential diagnoses whose ultrasound image may mimic a dissection. A frequently occurring but avoidable cause of misdiagnosis is idiopathic carotidynia. Ultrasound also enables differentiation between dissection and vasculitis or carotid web and detection of normal variants such as fenestration of the vertebral artery...
