Secondary Cerebral Ischemia at Traumatic Brain Injury Is More Closely Related to Cerebrovascular Reactivity Impairment than to Intracranial Hypertension.

Unlabelled: The purpose of this study was to investigate the relationship between the development of secondary cerebral ischemia (SCI), intracranial pressure (ICP) and cerebrovascular reactivity (CVR) after traumatic brain injury (TBI).

Methods: 89 patients with severe TBI with ICP monitoring were studied retrospectively. The mean age was 36.

Assessment of Cerebral Autoregulation in the Perifocal Zone of a Chronic Subdural Hematoma.

Introduction: The knowledge of conservative treatment modalities for a chronic subdural hematoma (CSDH) is still based on low-grade evidence. The purpose of this study was to evaluate the condition of the microcirculation and autoregulation in the perifocal CSDH zone for understanding of the mechanism of CSDH development.

Methods: Cerebral microcirculation was evaluated in patients with the aid of brain perfusion computed tomography (PCT) within the first day.

Comparative Analysis of Simultaneous Transcranial Doppler and Perfusion Computed Tomography for Cerebral Perfusion Evaluation in Patients with Traumatic Brain Injury.

Unlabelled: The aim was to investigate the feasibility of simultaneous comparison of cerebral circulation in major vessels and microvasculature in patients suffering traumatic brain injury (TBI) with or without intracranial hematomas (IH).

Methods: 170 patients were divided into two groups: Group 1 - diffuse TBI (75 patients); and Group 2 - TBI with IH (95 patients: 18 epidural, 65 subdural and 12 multiple). Perfusion computed tomography (PCT) for assessment of volumetric cerebral blood flow (CBF) was done 2-15 days after admission to hospital.

Cerebral Arterial Compliance in Polytraumazed Patients with Cerebral Vasospasm.

The purpose was to determine the status of the cerebral arterial compliance (cAC) in a concomitant head injury and cerebral vasospasm (CVS) with and without the development of intracranial hematomas (ICH). In Materials and Methods, we examined 80 polytrauma patients with severe TBI and CVS. During or immediately after dynamic helical computed tomography angiography (DHCTA), the monitoring of the transcranial Doppler of the MCA was recorded bilaterally with 2-MHz probes.

The Treatment of a Ruptured Anterior Communicating Artery (ACoA) Aneurysm with Coiling and Flow Disruptor (WEB-Device) and Management of Symptomatic Post-Interventional Delayed Vasospasm: A Case Report.

The article reports a clinical case illustrating a favorable outcome of endovascular treatment of a patient with a ruptured wide range neck ACoA aneurysm by WEB-Device. The peculiar characteristics of the pre-procedural period and the procedure are described.

Cerebral Arterial Compliance in Traumatic Brain Injury.

Objective: The main role of the cerebral arterial compliance (cAC) is to maintain the stiffness of vessels and protect downstream vessels when changing cerebral perfusion pressure. The aim was to examine the flexibility of the cerebral arterial bed based on the assessment of the cAC in patients with traumatic brain injury (TBI) in groups with and without intracranial hematomas (IHs).

Materials And Methods: We examined 80 patients with TBI (mean age, 35.
