Clinical Relevance of Cerebral Autoregulation Following Spontaneous Intracerebral Haemorrhage

Hypertensive intracranial haemorrhage is a common neurological emergency in clinical practice. The presence of an intracranial lesion of expansive focal nature can compress vascular structures and cause ischaemic effects. It is very common for these patients to have hypertensive peaks at admission, which may progress to rebleeding and neurological worsening. The safety of blood pressure reduction in patients with hypertension and intracranial haematomas is still a debatable subject due to lack of studies on cerebral autoregulation in this situation. The aim of this study is to discuss cerebral autoregulation in patients with spontaneous intracerebral haemorrhage based on scientific and personal evidence.
