Review Case ReportsPure acute subdural haematoma without subarachnoid haemorrhage caused by rupture of internal carotid artery aneurysm.
A 52-year-old female presented with disturbance of consciousness and clinical signs of tentorial herniation. Computed tomography showed a pure acute subdural haematoma (SDH) over the left convexity without subarachnoid haemorrhage. Cerebral angiography showed a saccular aneurysm at the junction of the left internal carotid artery and the posterior communicating artery. ⋯ Rupture of an aneurysm adhered to either the dura or falx and located in the subdural space may cause pure SDH. Therefore, ruptured intracranial aneurysm should be considered as a cause of non-traumatic SDH. Immediate removal of the SDH and aneurysmal clipping is recommended in such patients, even those in poor neurological condition.

Case ReportsUse of intra-aortic balloon pump counterpulsation for refractory symptomatic vasospasm.
Delayed neurologic deficits secondary to vasospasm remain a vexing problem. Current treatments include: hypertensive hypervolemic hemodilution (Triple-H) therapy, angioplasty, and intra-arterial papaverine administration. Significant morbidity and mortality still result from vasospasm despite these therapies. ⋯ Both patients had a substantial improvement in function, and are now capable of caring for themselves. We conclude that IABP may play an important role for improving cerebral blood flow in patients with vasospasm. It may be particularly useful in those patients with limited cardiac reserve.

Informed consent in neurosurgery: patients' recall of preoperative discussion.
Informed consent (IC) is an important principle of modern medicine and the quality of the process is likely to receive increasing attention in future due to complex surgical procedures and a development of social mistrust for medical treatment. Medico-legal action is also becoming an important influence on IC, in particular the extent of warning to be given about the degree of risk. Evaluation of IC, however, encounters various problems. One key element of a knowledgeable decision is an analysis based on the disclosed risks. ⋯ The general principles of memory apply and have implications in states of emotional arousal. Whereas education and age, unlike in previous reports, did not appear to influence recall, thus indicating that we had succeeded in tailoring IC to the individual, recall rate was low in most cases. Physicians should highlight the discrepancy and conflict between the requirements for the defence of medical practice in the law courts and the actual interests of patients. They should promote research to establish what really is 'appropriately informed consent'.

Microvascular decompression of the facial nerve for the treatment of hemifacial spasm: preoperative magnetic resonance imaging related to clinical outcomes.
The objective of this study was to investigate the role of preoperative three dimensional short-range magnetic resonance angiography (3D-TOF MRA) in predicting the clinical outcomes following microvascular decompression for the treatment of hemifacial spasm. ⋯ Preoperative 3D-TOF MRA can identify the relationship between the facial nerve and adjacent vessels in patients with a hemifacial spasm and assist in preoperative planning. This study suggests that 3D-TOF MRA is useful for selecting appropriate patients for surgical treatment and, to some extent, as an additional role for predicting the clinical outcome.
