Clinical study of changes of cerebral microcirculation in cerebral vasospasm after SAH.
Aim to investigate the changes of cerebral microcirculation after subarachnoid hemorrhage (SAH) and its association with cerebral vasospasm (CVS) after SAH. CTP was performed in 85 patients with SAH and 35 controls. Cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) were recorded for final analysis. ⋯ In 46 CVS patients, sCVS group presented significantly lower CBF and more prolonged MTT than asCVS patients (P<0.05). Seven cases with MTT between 6.31 and 12.72 s showed delayed ischemic neurological deficit (DIND), two of whom had hemiplegia, and one died. Our findings suggest that CTP examination contributes to uncover the changes of cerebral microcirculation after SAH, and the changes of cerebral microcirculation are associated with CVS post SAH.

Fever increased in-hospital mortality after subarachnoid hemorrhage.
Fever is a common clinical complication in patients with subarachnoid hemorrhage (SAH), and is usually related to prognosis in early stage of diseases. In our study, we try to help improve the outcome of SAH by assessing possible risk factors for fever and investigating the influence of fever on in-hospital mortality. ⋯ Poor Hunt-Hess grade, presence of IVH and older age are independent predictors of fever in SAH. Fever is closely related to increased in-hospital mortality after SAH.

In recent years the quality of ultrasound (US) imaging has improved considerably. The integration of three dimensional (3D) US with neuronavigation technology has created an efficient and inexpensive tool for intra-operative imaging in neurosurgery. Our experience is based on more than 900 operations with the intra-operative 3D ultrasound equipment SonoWand® and some operations with the research equipment Custux X. ⋯ Compared to intraoperative magnetic resonance imaging (ioMRI), 3D US technology is advantageous in different ways: it is flexible and can be used in any operation theatre. There is no need for special instruments, and no need for radiologists or technicians. It adds very little extra time to the operation, and the investment-costs are considerably lower than for ioMRI.

Analysis on death-associated factors of patients with subarachnoid hemorrhage during hospitalization.
The prognosis of patients with high-clinical-score subarachnoid hemorrhage remains poor, with early high mortality rate. Therefore, to predict the early outcome of patients after subarachnoid hemorrhage, several clinical factors were hypothesized to be related to death during hospitalization. ⋯ Increased white blood cell count may indicate poor outcomes for patients during hospitalization, even early death.

Electrocardiographic abnormalities in patients with intracerebral hemorrhage.
Stroke is frequently followed by electrocardiographic changes. Although electrocardiographic abnormalities are well known in ischemic stroke and subarachnoid hemorrhage, these changes have only rarely been investigated systematically in patients with intracerebral hemorrhage. The purpose of this study is to investigate the prevalence and characterization of ECG abnormalities in a consecutive series of ICH patients who had no history of heart disease. ⋯ Electrocardiographic abnormalities frequently occur after intracerebral hemorrhage, and these changes were not related to the level of the cerebral lesion, but were related to the location of the cerebral lesion and the outcome.
