[The management of cerebrovascular events]

Strokes (AVC) represent the 1st cause of death in the department of neurology of Dakar. The main characteristic of stroke is the brutality of the method of formation of neurological deficit. The vascular territory in question amends the clinical expression. Besides the motor deficit stroke can cause neuropsychological disorders affecting language, memory, activity gesture, recognition of oneself and its environment, space and extra corporeal body with the result intellectual deterioration. The mechanisms of stroke are dominated by atherosclerosis and embolic heart disease for ischemic stroke and hypertension and ruptures of vascular malformations for hemorrhagic stroke. CT scan remains the key consideration in determining the nature ischemic or hemorrhagic stroke. Because of its acuteness and rapid progress to irreversible injury stroke is a dramatically high priority medical emergency. The therapeutic strategy should follow a pattern efficient and fast leading to a specific care, gradual and coordinated by the 3rd hour. There is a need to recognize stroke, what is the nature (ischemic, hemorrhagic) and the cause, in order to consider a therapeutic care consistent. The care must start at the very beginning of the stroke and continued during transportation. In the acute phase of stroke, lower blood pressure should be gradual and it is recommended to respect an HTA in the order of 180/105 mm HG except under certain conditions (acute lung oedema, aortic dissection, infarction acute myocardial) that requires a rapid stabilization of blood pressure. Thrombolysis using alteplase (rt-PA) is called in neurovasalar units in case of stroke seen before the 3rd hour and in the absence of contraindications. Anticoagulants are shown in prevention of recurrence of stroke in the embolic heart disease with high risk of recidivism, in the carotid stenosis or vertebral basilar tight with hemodynamic impact downstream and in the extensive thrombosis. The treatment antiplatelet medication is indicated in other cases. The screening and the control of risk factors for vascular constitute an effective weapon for primary prevention. The rehabilitation motor, speech and language and occupational therapy can improve rehabilitation for patients. The prognosis vital and functional depend partly in the early and appropriate management of stroke and also in increasing of education and awareness of population and health care personnel and especially on the diffusion of the means of prevention primary
