Objectif Evaluer l’efficacité de la compression pneumatique

intermittente dans la prévention des thromboses veineuses profondes après un AVC

Etude - Etude multicentrique (94 centres en Grande-Bretagne),

randomisée, en parallèle, comparant la compression pneumatique intermittente à une prise en charge standard

Critères d’inclusion- Hospitalisation dans les 3 jours suivant un AVC- Patients alités, incapables de marcher sans aide

Méthodologie
