Management of multiple intracranial aneurysms: neuroanesthetic considerations of sickle cell disease.
Intracranial aneurysms are a common complication of sickle cell disease. The management of a patient with multiple intracranial aneurysms and sickle cell disease is described. The English language literature is reviewed. Neuroanesthetic management has traditionally been based on the avoidance of factors said to lead to erythrocyte sickling; however neuropathology typically arises from arterial intimal damage, not from venous sickling. Neuroanesthesia should be based on an appreciation of this pathophysiological model. Consideration of precipitants of vaso-occlusive crises, such as hypothermia, dehydration and possibly altered hemodynamics, should influence management.
