  Intracranial hemorrhage - Wikipedia, the free encyclopedia
Intracranial bleeding occurs when a blood vessel in the head is ruptured or leaks.
Intracranial hemorrhage is a serious medical emergency because the buildup of blood within the skull can lead to increases in intracranial pressure, which can crush delicate brain tissue or limit its blood supply.
Epidural hemorrhage is caused by trauma, and results from laceration of an artery, most commonly the middle meningeal artery.

 Neurosurgery: Encyclopedia of Surgery
Spontaneous intracranial hemorrhage (hemorrhage in the brain) is a condition characterized by hemorrhage in the brain (hemorrhagic stroke) that results in a sudden onset of neurologically worsening symptoms (that include focal neurologic deficits and loss of consciousness).
CT scans are helpful in identifying the intracranial hemorrhage, of which there are two types—subarachnoid hemorrhage and intracerebral hematoma.
CT scans are the best diagnostic tool for subarachnoid hemorrhage and are positive in the first 24 hours after the hemorrhage has been experienced in 90% of patients and in more than 50% in the first week.

An intracerebral hemorrhage is bleeding in the brain caused by the rupture of a blood vessel within the head.
The bleeding may be isolated to part of one hemisphere (lobar intracerebral hemorrhage) or it may occur in other brain structures, such as the thalamus, basal ganglia, pons, or cerebellum (deep intracerebral hemorrhage).
An intracerebral hemorrhage can be caused by a traumatic brain injury or abnormalities of the blood vessels (aneurysm or angioma).

 Diagnosis of spontaneous subarachinoid hemorrhage American Family Physician - Find Articles
Less common causes of primary subarachnoid hemorrhage are cavernous or venous angiomas, mycotic aneurysms, cortical thrombophlebitis and intracranial neoplasms (primary and metastatic).
The subarachnoid component of such hemorrhages is generally of far less significance than the intraparenchymal constituent, and the latter dictates the clinical presentation, management and outcome in most cases.
Intracranial aneurysms are rarely encountered before the third decade of life, reflecting the acquired nature of these lesions.

Traumatic intracranial aneurysms are rare, occurring in fewer than 1% of patients with cerebral aneurysms.
These aneurysms can present in a variety of ways, but are typically associated with an acute episode of delayed intracranial hemorrhage with an average time from initial trauma to aneurysm hemorrhage of approximately 21 days.

 Subdural hematomas
In this type of hemorrhage the events of labor simply produce excessive molding of the calvarium with relatively sudden stretching and tearing of the superficial venous channels over the cerebral hemispheres or venous sinuses in the posterior fossa.
Where an association between surfactant and the risk of intracranial hemorrhage was found, additional analyses were performed to attempt to identify intermediate physiologic events that might link administration of surfactant to the occurrence of intracranial hemorrhage.
A relationship between surfactant therapy and intracranial hemorrhage is probably not isolated to any particular surfactant preparation or method of delivery; studies comparing surfactants have shown no differences in rates of intracranial hemorrhage.

When intracranial hypertension is suspected, an immediate CT scan should be obtained to assess the degree of ICP increase and to identify the cause of the this.
The space may still be visible; however, with severe intracranial hypertension, the cistern is obliterated due to encroachment of brain tissue that normally forms the borders of the suprasellar cistern.
Depending on the cause of the intracranial hypertension, the suprasellar cistern may be totally obliterated in global or severe ICP increase.

Medical records were reviewed for all patients in the Trauma Registry from Jan. 2001 to Dec. 2002 taking pre-injury warfarin with CT scan evidence of intracranial hemorrhage; this time period corresponded to the initiation of a "Coumadin Protocol" which expedited triage of anticoagulated trauma patients to immediate evaluation by a physician.
Thirty-five patients were identified in the Protocol with intracranial hemorrhage; Mean International Normalized Ratio (INR) was 3.3±2.0, mean time to initiation of warfarin reversal was 3.9±3.4 hours with a mortality of 37% (13 patients).
We conclude from these data that a trauma center protocol for rapid identification of intracranial hemorrhage without a concomitant therapeutic protocol does not affect survival 'in head injured patients on pre-injury warfarin.
