OBJECTIVE To summarize the current knowledge of the mechanisms leading to rebleeding and the prevention of rebleeding after subarachnoid hemorrhage (SAH). METHODS A literature search was performed to investigate factors associated with rebleeding after SAH. RESULTS The review of the literature revealed that rebleeding is a complex and multifactorial event involving hemostasis, pathophysiologic, and anatomic factors. Administration of antifibrinolytics has been shown to have a dramatic effect on the rebleeding rate, so changes in coagulation and fibrinolysis must be involved in rebleeding. CONCLUSIONS Further studies are warranted before the exact mechanisms leading to rebleeding are established and the optimal preventive measures are made available. At the present time, antifibrinolytic therapy remains the only realistic protective measure during the initial 6 hours after SAH during which the rebleeding rate is highest.

UI	MeSH Term	Description	Entries
D006487	Hemostasis	The process which spontaneously arrests the flow of BLOOD from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements (eg. ERYTHROCYTE AGGREGATION), and the process of BLOOD COAGULATION.	Hemostases
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000933	Antifibrinolytic Agents	Agents that prevent fibrinolysis or lysis of a blood clot or thrombus. Several endogenous antiplasmins are known. The drugs are used to control massive hemorrhage and in other coagulation disorders.

D012307	Risk Factors	An aspect of personal behavior or lifestyle, environmental exposure, inborn or inherited characteristic, which, based on epidemiological evidence, is known to be associated with a health-related condition considered important to prevent.

D013345	Subarachnoid Hemorrhage	Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.
