Systemic Inflammation During Recanalization of Cerebral Arterial Occlusion

Completed

• Conditions: Stroke; Systemic Infection
• Interventions: Biological: Blood sample

• Registration Number: NCT04731584
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

Strokes management, secondary to proximal arterial occlusion, by endovascular thrombectomy (TM) is now well established. The immuno-inflammatory events of reperfusion after TM are discussed. Systemic inflammation is a major factor suggested to explain the limited recovery of the ischemic parenchyma. Understanding these phenomena is necessary before developing an immunomodulatory strategy.

Arm && Interventions

Group	Intervention	Description
Control	Blood sample	Population of control patients, consisting of patients admitted on an outpatient basis for a diagnostic cerebral arteriography.
AVC	Blood sample	Patients hospitalized for TM after a proximal ischemic stroke of the middle cerebral artery and whose reperfusion is satisfactory (TICI 2b, 2c and 3). Additional blood sample will be taken during usual treatment the day of the stroke.

Primary Outcome Measures

Name	Time	Method
Inflammation parameters description	1 day	Inflammatory parameters such as CRP, IL-6, IL-10, HLA-DR, TNF-alpha, polymorphonuclear chemotaxis, CD-4, T-lymphocytes will be measure in blood sample
