Case ReportsAcute subdural hematoma from ruptured cerebral aneurysm.
The combination of ruptured aneurysms with acute subdural hematomas (aSDHs) is a rare presentation. Patients with aSDH associated with aneurysmal bleeding represent a subgroup within the spectrum of aneurysmatic hemorrhage. We summarize the clinical characteristics, diagnostic evaluation, and management of a series of cases presenting with aSDH associated with aneurysmal subarachnoid hemorrhage (SAH). ⋯ The incidence of aSDH associated with SAH is low. Most of the patients with aSDH due to a ruptured aneurysm present in exceptionally poor neurological condition. Nevertheless, rapid surgical treatment of the hematoma and aneurysm obliteration can lead to a favorable outcome. Routine CTA should be performed in all patients presenting with an aSDH associated with SAH and no clear history of trauma.

Long-term outcome and quality of life after nonaneurysmal subarachnoid hemorrhage.
Nonaneurysmal subarachnoid hemorrhage (SAH) is an uncommon form of SAH. As nonaneurysmal SAH is often concentrated around the pons and midbrain, the term perimesencephalic SAH (pmSAH) is widely accepted to describe this entity, though there are patients with a more widespread distribution of subarachnoid blood (non-pmSAH). The outcome of pmSAH is commonly regarded as good, although often outcome is not analyzed using standardized tools of outcome measurement. In this study we focused on the patient's quality of life after nonaneurysmal SAH. ⋯ Nonaneurysmal SAH is a begnin entity, though there is a difference between pmSAH and non-pmSAH in outcome. Self-evaluations of vitality and individual health in both groups are often experienced as reduced, thus imposing the question of whether neurological rehabilitation should be recommended despite good neurological outcome.

Intracranial pressure pulse amplitude during changes in head elevation: a new parameter for determining optimum cerebral perfusion pressure?
During short-term postural changes, the factors determining the amplitude of intracranial pulse pressure (ICPPA) remain constant, except for cerebrovascular resistance (CVR). Therefore, it may be possible to draw conclusions from the ICPPA onto the cerebrovascular resistance (CVR) and thus the relative change in cerebral perfusion pressure (CPP). ⋯ Head elevation is an important part of the ICP and CPP therapy in neurointensive care. When searching for the patient-specific optimum upper body position, ICPPA may provide additional information. Providing that the cerebral autoregulation is intact, the lowest ICPPA of a patient corresponds to the individual upper body position with the highest CPP.

Outcome correlates with blood distribution in subarachnoid hemorrhage of unknown origin.
Between 15 and 30 % of patients with subarachnoid hemorrhage (SAH) have no bleeding source and usually have a benign clinical course and outcome. The objectives of this study were to classify the pattern of blood distribution on initial computed tomography (CT) and to correlate it with clinical outcome in aneurysmal (ASAH) and SAH of unknown origin (SAHuO). ⋯ In SAH of unknown origin, a new classification allows to predict outcome based on the extent of blood on CT.
