Case Reports[Carotid dissection during angioplasty for vasospasm induced by subarachnoid haemorrhage. The use of multimodal cerebral monitoring].
We report the case of a 54-year-old woman presenting subarachnoid haemorrhage. She experienced multiple vasospasms and treatment included triple-H (hypervolaemia, hypertension, and haemodilution) and endovascular therapies. ⋯ Combined brain tissue partial pressure of oxygen monitoring and transcranial echo-Doppler could have facilitated early diagnosis. Despite successful revascularization of right internal carotid by stenting, this complication caused acute stroke with refractory intracranial hypertension.

The objectives for using sedation in neurointensive care unit (neuroICU) are somewhat different from those used for patients without severe brain injuries. One goal is to clinically reassess the neurological function following the initial brain insult in order to define subsequent strategies for diagnosis and treatment. Another goal is to prevent severely injured brain from additional aggravation of cerebral blood perfusion and intracranial pressure. ⋯ In that situation, a multimodal monitoring is needed to overcome the lack of clinical monitoring, including repeated measurements of intracranial pressure, blood flow velocities (transcranial Doppler), cerebral oxygenation (brain tissue oxygen tension), and brain imaging. The ultimate stop of neurosedation can distinguish between no consciousness and an alteration of arousing in brain-injured patients. During this period, an elevation of intracranial pressure is usual, and should not always result in reintroducing the neurosedation.
