Patterns of stroke between university hospitals and non-university hospitals in mainland China: a prospective multicenter hospital-based registry study
In China, stroke has risen to the first commonest cause of death. Currently published data on stroke mainly come from university hospitals, and less from community hospitals, especially lacking information on stroke focusing on the differences between university hospitals and non-university hospitals. Therefore, we aimed to investigate the patterns and the differences of acute stroke between university hospitals and non-university hospitals in China.

Vitamin D deficiency is not associated with outcomes in aneurysmal subarachnoid hemorrhage patients, a case control study
Vitamin D deficiency has been associated with increased risk and adverse outcomes in many clinical settings including cardiovascular disease, stroke, and critically ill patients. Therefore we aimed to determine whether vitamin D deficiency had any effect in aneurysmal subarachnoid hemorrhage (aSAH) clinical outcomes.

Endovascular Treatment of Tandem Common Carotid Artery Origin and Distal Intracranial Occlusion in Acute Ischemic Stroke
We present two cases with a pattern of tandem occlusion consisting of proximal obstruction at the origin of the common carotid artery (CCA) with concomitant intracranial occlusion treated by endovascular techniques.

Prone Versus Sitting Position in Neurosurgery —Differences in Patients' Hemodynamic Management
Neurosurgery in general anesthesia exposes patients to hemodynamic alterations in both the prone and the sitting position. We aimed to evaluate the hemodynamic profile during stroke volume –directed fluid administration in patients undergoing neurosurgery either in the sitting or the prone position.

Health Care Costs of Spontaneous Aneurysmal Subarachnoid Hemorrhage for Rehabilitation, Home Care, and In-Hospital Treatment for the First Year
Given the young age of onset and high probability of long-term disability after subarachnoid hemorrhage (SAH), the financial impact is expected to be substantial. Our primary objective was to highlight subsequent treatment costs after the acute in-hospital stay, including rehabilitation and home care, compared with costs for ischemic stroke.

Prone versus sitting position in neurosurgery – differences in patients’ hemodynamic management
Neurosurgery in general anesthesia exposes patient to hemodynamic alternations both in prone and sitting position. As the comparison of the sitting and prone position in neurosurgery is scarce, we aimed to evaluate hemodynamic profile during stroke volume-directed fluid administration in patients undergoing neurosurgery either in sitting or prone position.

Effectiveness of Intracranial Percutaneous Transluminal Angioplasty or Stenting for Atherosclerotic Vertebrobasilar Artery Occlusion in the Acute Phase of Ischemic Stroke
Although short-term clinical outcomes after basilar artery stent placement have been reported previously, effectiveness of intracranial stenting for vertebrobasilar artery occlusion in the acute phase of ischemic stroke is unclear.

Development of a De Novo AVM Following Ischemic Stroke: Case Report and Review of the Current Literature
Arteriovenous Malformations (AVMs) are hypothesized to be static, congenital lesions developing as early as 4 weeks of fetal life. New literature has shown that AVMs may represent dynamic and reactive vascular lesions arising from cerebral infarction, inflammation, or trauma. A literature search reveals 17 previously reported cases of new AVM formation after previous negative imaging studies. This reactive development or “second hit” theory suggests that at a molecular level, growth factors may play a vital role in aberrant angiogenesis and maturation of an arterio-venous fistula into an AVM.

Volume of Brain Herniation in Patients with Ischemic Stroke After Decompressive Craniectomy
Decompressive craniectomy procedures are performed in patients with malignant intracranial hypertension. A bone flap is removed to relieve pressure. Later, a second operation is performed to reconstruct the skull after brain swelling has resolved. This surgical treatment would be improved if it were possible to perform a single operation that decompressed the brain acutely and eliminated the need for a second operation. To design a device and procedure that achieve this objective, it is essential to understand how the brain swells after a craniectomy procedure.
