Bleeding, hemorrhage, haemorrhage or blood loss is blood escaping from the circulatory system from damaged blood vessels. [1] Bleeding can occur internally , or externally either through a natural opening such as the mouth , nose , ear , urethra , vagina or anus , or through a puncture in the skin .
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both. [ 3 ] [ 4 ] [ 1 ] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other).
A subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. Trauma can also cause SAH when the arteries and veins coursing through the subarachnoid space are ruptured.
Epidural hemorrhage is bleeding between the dura mater and the skull. [4] It is commonly associated with damage to the middle meningeal artery, often resulting from a skull fracture. Subdural hemorrhage is bleeding between the dura mater and the arachnoid. [4] Intracerebral hemorrhage is bleeding within the brain tissue itself. [4]
Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
If the bleeding is so heavy that you’re soaking dish towels, and it won’t stop even with firm pressure on the soft parts of your nose or two rounds of decongestant nasal sprays with pressure ...
Intra-axial hemorrhage is bleeding within the brain itself, or cerebral hemorrhage. This category includes intraparenchymal hemorrhage, or bleeding within the brain tissue, and intraventricular hemorrhage, bleeding within the brain's ventricles (particularly of premature infants). Intra-axial hemorrhages are more dangerous and harder to treat ...
A hemorrhagic infarct is determined when hemorrhage is present around an area of infarction. Simply stated, an infarction is an area of dead tissue or necrosis. [1] When blood escapes outside of the vessel (extravasation) and re-perfuses back into the tissue surrounding the infarction, the infarction is then termed a hemorrhagic infarct (infarction). [1]
