Objective: The purpose of this study was to assess the value of sonographic examination of congenital variations of the extracranial vertebral artery associated with posterior circulation ischemia in children.
Methods: Sonography was performed on the vertebral arteries of 82 patients aged 2.5 to 14 years with a history of headache, vertigo, and syncope. An additional 86 unaffected children aged 2 to 14 years were included as a control group. Indices such as the diameter, passage, and morphologic characteristics of the vertebral artery were measured, as well as the arterial volume. The median values of these parameters were used for comparisons.
Results: A comparison between the control and 5 case groups showed that the bilateral diameter and volume in these 6 groups had significant variations (P < .05). A narrow diameter and abnormal passage of the vertebral artery resulted in reduced blood flow and an inadequate blood supply in the posterior circulation. There were 42 cases found to have congenital variations of the extracranial vertebral artery, 12 cases of congenital asymmetry, 15 cases of tortuosity, 5 cases of bilateral congenital asymmetry with tortuosity, 6 cases of congenital hypoplasticity, and 4 cases of an abnormal path.
Conclusions: Certain children with a history of recurrent signs of vertigo, headache, and syncope were found to be afflicted with congenital variations of the extracranial vertebral artery. Sonography not only revealed the morphologic variations of the extracranial vertebral artery but also allowed an assessment of changes in blood flow such that posterior circulation ischemia could be determined.

During dissection of a 70-year-old male donor, several anatomical variations were observed, highlighted by a bilateral variant middle scalene muscle in the superolateral thoracic wall. The variant scalene muscle was traced from the transverse processes of cervical vertebrae to the fourth rib with a pronounced fascial slip. The elongated middle scalene muscle was thick in girth and abnormally wide at its insertion (56.

Introduction: Dynamic vertebral artery insufficiency is a rare vascular phenomenon characterized by insufficient flow of the posterior cerebral circulation induced by dynamic motion of the head. Prior case reports have been limited to vertebral artery occlusion by cervical osteophytes or other structural impingements.
Case Report: In this case report, we discuss the unusual case of a 61-year-old female with a history of vertigo, diplopia, nystagmus, and left subclavian stenosis admitted to the hospital for syncope elicited by a left head turn and left shoulder raise.

Lateral medullary syndrome (LMS) is a neurological disorder usually presenting as loss of pain and thermal sensation over the ipsilateral face and contralateral half of the body, ipsilateral limb ataxia, Horner's syndrome, dysphagia, nystagmus, hiccups among other symptoms but never with limb weakness. In the present case, the patient presented with ipsilateral hemiparesis, which can be attributed to the extension of the infarct caudally beyond the pyramidal decussation, affecting the corticospinal fibers in the upper cervical cord, a variant of LMS, known as Opalski syndrome (OS).

background: : Intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) related to underlying intracranial artery dissection (IAD) poses potential risks, including the exacerbation of intramural hematoma and the rupture of the dissected arterial wall. However, the safety of IVT in this specific population remains uncertain.
aims:: This study aimed to assess whether IAD is associated with an increased risk of intracranial hemorrhage (ICH) following IVT and to evaluate its impact on functional outcomes.

Background: The presence of significant tortuosity in access routes to aneurysms can interfere with catheter guidance and manipulation and significantly impact treatment strategies.
Observations: In this report, the authors combined intentional staged aneurysm embolization with the construction of a new direct access route, which they call a "highway bypass," for a symptomatic posterior circulation cerebral aneurysm that was difficult to access with a catheter. Notably, the highway bypass is used for catheter passage, and technical tips should be considered.
