A case which caused cerebral perfusion disturbance by antidromic cerebral perfusion to dissecting aortic aneurysm.

Cerebral perfusion in sepsis

Cerebral perfusion (SPECT) studies.

This article forms part of our 'Tests and results' series for 2013, which aims to provide information about common tests that general practitioners order regularly. It considers areas such as indications, what to tell the patient, what the test can and cannot tell you, and interpretation of the results.

Cerebral perfusion and stroke.

Stroke is a heterogeneous syndrome caused by multiple disease mechanisms, but all result in a disruption of cerebral blood flow with subsequent tissue damage. This review covers the mechanisms responsible for regulation of the normal cerebral circulation, and how they are disrupted in disease states. A central concept in treating patients with acute ischaemic stroke is the existence of an ischa...

Dynamic cerebral autoregulation and monitoring cerebral perfusion.

Cerebral autoregulation (CA) describes the capability of the brain to maintain its flow as relatively stable over a wide rage of mean arterial pressures (MAPs), for example, from 60 to 150 mm Hg. Because the brain is encompassed in the skull, CA is vital for preventing cerebral edema and hemorrhage, as illustrated in some patients experiencing acute liver failure.1 Also, CA counteracts the effe...

Driving cerebral perfusion pressure with pressors: how, which, when?

In traumatic brain injury, cerebral hypoperfusion is associated with adverse outcome, particularly in the early phases of management. This has resulted in the increased use of drugs such as adrenaline, noradrenaline, dopamine and phenylephrine to augment or maintain systemic blood pressures at near normal levels. This is now part of standard practice and is endorsed by the Brain Trauma Foundati...
