Cervical spine trauma (CST) may result in vertebral artery injury (VAI), increasing the risk of developing stroke. Stroke risk following CST is poorly reported. ⋯ VAI occurs with a high incidence in penetrating CST. Although stroke risk following penetrating and blunt CST did not vary significantly, they resulted in serious complications in a group of patients. Further study of this patient population is required to provide high-level, evidence-based preventions for VAI complications.

Recent literature suggests there are sex differences in delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). Our study serves to compare sex differences in radiographic vasospasm, DCI, and clinical outcome after aSAH, and to determine whether there are age-dependent differences. ⋯ Female sex is associated with a higher risk of radiographic vasospasm, clinical deterioration, and cerebral infarction. Furthermore, this association appears to be age-dependent. This study further supports the unique role of sex, and highlights the need to better understand the possible role of female hormones in the development of complications of subarachnoid hemorrhage.

Case Reports
Intracranial Approach for Retrieval of the Condylar Head Following Avulsion into the Middle Crania Fossa.
Dislocation of the mandibular condyle into the middle cranial fossa is a rare injury that can be seen after facial trauma. Early identification of condyle dislocation into the middle cranial fossa was difficult until the development of computed tomography, and diagnosis was often significantly delayed after the initial trauma. ⋯ To our knowledge, this complete avulsion of the condyle into the middle cranial fossa requiring an intracranial approach for condylectomy is extremely rare. We discuss the surgical management options for reduction and fixation accomplished in a multidisciplinary approach involving neurosurgery and oral maxillofacial surgery.

Superficial temporal artery-middle cerebral artery (STA-MCA) bypass may be used to augment cerebral blood flow in patients with select cerebrovascular pathologies or after failed attempts at revascularization. In this article we describe the use of balloon angioplasty to boost the flow of the external carotid artery (ECA) including the STA to be later used as a donor artery for a STA-MCA bypass procedure. ⋯ This case highlights a unique strategy for the management of internal carotid artery occlusion in combination with an ipsilateral ECA stenosis. We also demonstrate the utility of endovascular adjuncts to open vascular surgery when complex patterns of stenosis or occlusion exist.

The incidence of traumatic arteriovenous fistula (TAVF) between the middle meningeal artery (MMA) and the petrosal vein (PV) is rare. Although TAVF has been reported involving the MMA several sinus and veins, this is the first incidence of a fistula involving the extracranial MMA and PV. ⋯ This is the first incidence of a fistula connecting the extracranial MMA and PV. We managed the patient with only coil embolization without any further neurologic deficits.
