Brief Summary:
In our ICU, it could notice that patients with cerebral arterio-venous malformation (AVM) treated with embolization develop more severe Ventilator Associated Pneumoniae (VAP) compare to other patients hospitalized for neurological diseases. The Dimethylsulfoxyde (DMSO), the solvent of the embolization implant, is known to have immune effect on vitro analysis. The investigator want to prove that exposition to embolization implant for a cerebral AMV modify the cytokines production involved the system immune's regulation.
Detailed Description:
Cerebral AVM are defined by abnormal connections between arteries and veins. For treatment of this vascular malformation, embolization is the gold standard. Embolization agent is made with vinylic alcohol ethylene (EVOH) copolymer which (the embolization implant) and the DMSO which is the solvent. During the injection of the product, DMSO dissipates in the bloodstream, and the EVOH precipitates and forms the embolus. It knows that DMSO had in-vitro immune effect (inhibits signalizations ways of innate and acquired immune response, decrease of pro-inflammatory cytokines production and decrease INF-γ and TNF-α production). DMSO could decrease activation and recruitment of leukocytes, which could expose patients to an increased risk of infection.
The investigator will dose cytokines in 3 blood samples (preoperative, H+6 and H+24) in planned patient's hospitalized for cerebral AVM embolization. The cytokine content of the plasmas will be analyzed with multiplex ELISA technic
