	Cerebral hemorrhage - Wikipedia, the free encyclopedia
		Subarachnoid hemorrhage, which accounts for 5 to 10 percent of strokes (Weibers 2001) is one of the deadliest type of strokes.
		Selected patients with subarachnoid hemorrhage due to a ruptured aneurysm require emergency surgery to "clip" the aneurysm off from the normal brain blood circulation, and they receive nimodipine, a drug shown to reduce incidence of vasospasm, a complication of this type of stroke.
		Hemorrhagic transformation is the phenomenon in which blood vessels weakened by ischemic stroke rupture to cause hemorrhage in addition (Stroke Center, 2005; Jauch, 2003).

	Subarachnoid hemorrhage - Wikipedia, the free encyclopedia
		A subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space surrounding the brain, i.e., the area between the arachnoid and the pia mater.
		Lumbar puncture may be needed for diagnosis in small subarachnoid bleeds that may not be detected on CT scans; the presence of xanthochromia -- a yellow tinge to the cerebrospinal fluid consequent to breakdown of blood -- is indicative of SAH, whereas gross blood may merely indicate a traumatic lumbar puncture.
		This may be by craniotomy and external clipping of the bleeding vessel or aneurysm, or by interventional radiology (neuroradiology), which employs transfemoral angiography and inserting of metal coils to stem the bleeding (which is especially useful in aneurysmatic hemorrhage).

	Subarachnoid hemorrhage
		Subarachnoid hemorrhage is bleedingÂ between the middle membrane covering of the brain and the brain itself.
		Unlike the majority of hemorrhages that are caused by arterial ruptures, this type is thought to be caused by a ruptured vein or capillary.
		Subarachnoid hemorrhage occurs when there is bleeding into the space between the brain and the arachnoid membrane (the middle membrane covering the brain).

	Subarachnoid Hemorrhage \| AHealthyMe.com
		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 occur with little or no warning and are frequently caused by ruptured aneurysms or blood vessel abnormalities in the brain.
		Spontaneous subarachnoid hemorrhages are often due to an aneurysm (a bulge or sac-like projection from a blood vessel) which bursts.

	Diagnose-Me: Condition: Subarachnoid Hemorrhage
		A subarachnoid hemorrhage occurs when bleeding from a damaged blood vessel causes an accumulation of blood at the surface of the brain.
		When a subarachnoid hemorrhage is caused by a ruptured saccular aneurysm, the aneurysm usually is located where a blood vessel branches from one of these large arteries.
		Subarachnoid hemorrhages commonly cause arteries nearest to the site of bleeding to spasm and become narrower, so medicines may be used to prevent this reaction.

	Subarachnoid hemorrhage
		A subarachnoid hemorrhage is bleeding from a damaged artery at the surface of the brain.
		A mechanical ventilator frequently is used to cause someone who has had a subarachnoid hemorrhage to breathe faster, which lowers the carbon dioxide level in the blood and causes less blood to flow into the brain.
		Subarachnoid hemorrhages commonly cause arteries nearest to the site of bleeding to spasm and become narrower, so medicines such as nimodipine may be used to partially protect you against this reaction.

		Subarachnoid hemorrhage may be separated into traumatic and spontaneous varieties (Table 1).
		Aneurysms account for 70 to 80 percent of primary subarachnoid hemorrhages; AV malformations are responsible for 5 to 10 percent.
		Secondary subarachnoid hemorrhage is characterized by bleeding from a deeper parenchymal lesion toward the pial surface, with subsequent extension into the subarachnoid space.

		Subarachnoid hemorrhage (SAH) is a kind of stroke caused by bleeding into the spaces around the brain - a very life-threatening situation.
		The subarachnoid space is the area between the brain and the skull.
		As blood spills into the subarachnoid space the area of brain that artery was supplying is now deprived of blood – called a stroke.

		A subarachnoid hemorrhage is sudden bleeding between the brain and the membranes that cover it.
		This is a weakness in the wall of an artery causing a pouch or a swelling in the blood vessel.
		If a subarachnoid hemorrhage is confirmed and the patient is medically and neurologically stable, members of the stroke team will confer about the timing and choice of the best diagnostic and treatment options.

		Similarly, intraventricular hemorrhage or hydrocephalus associated with subarachnoid hemorrhage may be conditions where insertion of a ventricular drainage system will alleviate elevate intracranial pressure (ICP).
		If the head CT shows diffuse subarachnoid hemorrhage, hydrocephalus, or an intraparenchymal hemorrhage which could be removed surgically with some hope of neurologic improvement, a ventriculostomy is inserted.
		Although we have been able to improve the outcome of patients in poor neurologic condition after subarachnoid hemorrhage, it should be noted that of 32 patients treated, 16 were patients whose poor neurologic condition was due to a second hemorrhage from their aneurysm.

	Bleeding Strokes Called Subarachnoid Hemorrhage May Be Preventable
		Researchers say subarachnoid hemorrhage accounts for only about 3% of all strokes, but it is among the most deadly types of stroke.
		To see what factors might increase the risk of subarachnoid hemorrhage, the study compared lifestyle and health factors among a group of 312 people between the ages of 18 and 49 who had this type of bleeding stroke to a similar group of 618 healthy adults.
		Those who had suffered a subarachnoid hemorrhage were much more likely to be smokers, have high blood pressure, or have used cocaine in the last three days than the others.

		The prognosis for patients with subarachnoid hemorrhage is poor; approximately 40% of patients die in the first 30 days after aneurysmal rupture.
		The prognosis for patients with subarachnoid hemorrhage who are correctly diagnosed in good clinical condition (Hunt and Hess grades I and II) is good with treatment, while those who are in poor neurological condition (grades IV and V) have a worse prognosis [Table 5].
		Although subarachnoid hemorrhage (SAH) could theoretically be prevented by either prevention of aneurysm formation or treatment of formed aneurysms, neither of these approaches has proved effective.

	IMAGING OF CEREBROVASCULAR DISEASE
		In cases of subarachnoid hemorrhages, the most common aneurysms are posterior communicating (38%), anterior communicating (36%), and middle cerebral (21%).
		A subarachnoid hemorrhage with blood in the lateral ventricle is usually due to an anterior communicating aneurysm.
		For that reason, a three- or four-vessel angiogram should always be performed in patients with subarachnoid hemorrhage, even though an aneurysm might be found on the first vessel studied.

		A subarachnoid hemorrhage is bleeding onto the surface of the brain, most often caused by a break in a blood vessel at the base of the brain.
		A subarachnoid hemorrhage often occurs without warning and is life threatening.
		In a subarachnoid hemorrhage, the aneurysm most often breaks at the base of the brain and the blood flows into the subarachnoid space, mixing with the fluid that surrounds the brain and spinal cord (cerebrospinal fluid).
