Inflammation and Coagulation Factors for Predicting Cerebral Edema After SAH

Inflammation and Coagulation Factors in Cerebrospinal Fluid for Predicting Persistent Cerebral Edema After Subarachnoid Hemorrhage

Explore the role of Inflammation and coagulation factors in cerebrospinal fluid for predicting persistent cerebral edema after subarachnoid hemorrhage

Inclusion Criteria:

• Subarachnoid hemorrhage patients admitted to our neurosurgery department with modified Fisher Scale 3-4, with a confirmed radiographic diagnosis.

Exclusion Criteria:

• Angiogram-negative patients, patients with a history of trauma or previous brain injury (stroke, hemorrhage, surgery et al. which left associated chronic changes on CT), arteriovenous malformation, radiological data lost, accompany with serious comorbidities before subarachnoid hemorrhage onset (such as coagulation defects, uncontrollable hypertension, and arrhythmia et.al.), initial radiological data performed more than 3 days after SAH onset
