Increased blood coagulation is associated with poor neurological outcome in aneurysmal subarachnoid hemorrhage.

Background And Purpose: Patients with aneurysmal subarachnoid hemorrhage (aSAH) have demonstrated increased blood coagulation which is thought to contribute to delayed cerebral ischemia (DCI) and to a worse outcome. Therefore, we sought to determine whether this increased blood coagulation, detectable with rotational thromboelastometry (ROTEM), was associated with DCI and neurological outcome.

Methods: We conducted a prospective observational study of 60 consecutive adult aSAH patients.
