  Subarachnoid space   (Site not responding. Last check: 2007-10-31)
The subarachnoid space is bounded by the spinal meninges.
The subarachnoid space extends from the basal cisterns surrounding the brainstem superiorly, to its termination opposite the level of the second sacral vertebra (Figure 16.1).
Posteriorly, in the mid-line, it extends from the posterior median sulcus to the dura as the posterior subarachnoid septum.

 Subarachnoid space - Wikipedia, the free encyclopedia
The Subarachnoid Cavity (subarachnoid space) is the interval between the arachnoid mater and pia mater.
It is occupied by a spongy tissue consisting of trabeculæ (delicate connective tissue filaments that extend from the arachnoid mater and blend into the pia mater) and intercommunicating channels in which the subarachnoid fluid is contained.

 Subarachnoid hemorrhage
A subarachnoid hemorrhage is an abnormal and very dangerous condition in which blood collects beneath the arachnoid mater, a membrane that covers the brain.
Spontaneous subarachnoid hemorrhages are often due to an aneurysm (a bulge or sac-like projection from a blood vessel) which bursts.
Whether through trauma or disease, subarachnoid hemorrhages are caused by blood being released by a damaged blood vessel and accumulating in the subarachnoid space.

 Calcium antagonists for aneurysmal subarachnoid haemorrhage
A subarachnoid haemorrhage is a bleed over the surface of the brain, in the so-called subarachnoid space, which is the very small space between the brain and the skull, and which contains blood vessels that supply the brain.
The outcome of patients after subarachnoid haemorrhage is generally poor: half the patients die within one month after the haemorrhage, and of those who survive the initial month, half remain dependent on someone else for help with activities of daily living (eg: walking, dressing, bathing).
The cause is not exactly known, but probably relates to narrowing of blood vessels as a reaction to the presence of blood in the subarachnoid space, between the skull and the brain.

 Aneurysms: Encyclopedia of Neurological Disorders
Ruptures of intracerebral aneurysm result in stroke (loss of blood supply to tissue) and bleeding into the subarachnoid space).
Dilations, or ballooning, of blood vessels to form an aneurysm are particularly dangerous because they increase the chance of arterial rupture and subsequent bleeding into brain tissues (a hemorrhagic stroke).
The presence of blood in the cerebrospinal fluid withdrawn during a lumbar puncture is also diagnostic evidence for blood leaking into the subarachnoid space.
