TicAgreLor Versus Placebo to Prevent Cerebral ISCHemia in anEuRysmal Low Grade SAH A Double Blinded Randomised Controlled Study

Summary

Among aneurysmal subarachnoid hemorrhage (aSAH) survivors, ischemic injuries such as peri procedural thromboembolic events (TEE) and delayed cerebral ischemia (DCI) represent the most important disabling complications. However, preventive strategies are limited. Platelet activation mechanisms play a critical role in the pathophysiology of TEE and DCI. The results of several meta analyses suggested that use of antiplatelet drugs (APD) could reduce the risk of TTE/DCI. We aim to evaluate in patients with a low grade aSAH (WFNS 1 to 3) that occurred for less than 72 hours ago, the effect of 14 days course of ticagrelor vs placebo, initiated at the beginning of the endovascular treatment of the aneurysm, on the ischemic complications (peri-procedural symptomatic and asymptomatic TEE and/or neurological worsening due to DCI) occurring within 14 days of the endovascular treatment of the aneurysm.
