cerebral hemorrhage

Etymology: L, cerebrum + Gk, haima, blood, rhegnynei, to burst forth

a hemorrhage from a blood vessel in the brain. Three criteria used to classify cerebral hemorrhages are location (subarachnoid, extradural, subdural), kind of vessel involved (arterial, venous, capillary), and origin (traumatic, degenerative). Each kind of cerebral hemorrhage has distinctive clinical characteristics. Most cerebral hemorrhages occur in the region of the basal ganglia and are caused by the rupture of a sclerotic artery as a result of hypertension. Other causes of rupture include congenital aneurysm, cerebrovascular thrombosis, and head trauma.

observations Bleeding may lead to displacement or destruction of brain tissue. Extensive hemorrhage is usually fatal. Depending on the extent and the location of the damaged tissue, residual effects may include aphasia, diminished mental function, hemiplegia, or disturbance of the function of a special sense.

interventions A computed tomography scan may be performed to locate the lesion and to differentiate the hemorrhage from an embolus or thrombus, or cerebral angiography may be used for these purposes. Lumbar puncture may be performed to reveal blood in the spinal fluid if subarachnoid bleeding is suspected, but computed tomography must be performed first because of the risk of brain herniation if high intracranial pressure is present. Surgery is sometimes necessary to stop the bleeding and to prevent death from greatly increased intracranial pressure, although it has not been shown to improve long-term outcome. Treatment is usually supportive.

cerebral hemorrhage,

n an emergency condition indicated by the rupturing of a blood vessel in the brain and the subsequent bleeding into the tissues of the brain. Type of stroke or cerebrovascular accident (CVA).

hemorrhage

the escape of blood from a ruptured vessel. Hemorrhage can be external, internal, or into the skin or other tissues. Blood from an artery is bright red in color and comes in spurts; that from a vein is dark red and comes in a steady flow.

Hemorrhages in particular anatomical sites may be found under their specific anatomical headings.

alimentary tract hemorrhage

includes hematochezia, melena.

cancer-associated hemorrhage

see paraneoplastic hemorrhage (below).

capillary hemorrhage

oozing of blood from minute vessels.

cerebral hemorrhage

see brain hemorrhage.

concealed hemorrhage

internal hemorrhage.

ecchymotic hemorrhage

see ecchymosis.

exercise-induced pulmonary hemorrhage

see exercise-induced pulmonary hemorrhage.

fibrinolytic hemorrhage

that due to abnormalities in the fibrinolytic system and not dependent on hypofibrinogenemia.

internal hemorrhage

that which occurs into cavities, e.g. hemoperitoneum, or into tissues, e.g. vulvar hematoma in mares. The only evidence of illness may be extreme pallor and weakness. There may be moderate dyspnea and other signs related to the distention of individual organs.

hemorrhage intra-abdominal

see hemoperitoneum.

intra-articular hemorrhage

see hemarthros.

intracranial hemorrhage

bleeding within the cranium, which may be extradural, subdural, subarachnoid or cerebral.

intraocular hemorrhage

see hyphema.

mesenteric hemorrhage

uncommon syndrome caused by leakage of blood into the potential space between the two serosal layers of the mesentery. An extensive hemorrhage causes severe abdominal pain, shock, some blood-staining of peritoneal fluid and leakage of blood into the intestinal lumen.

paraneoplastic hemorrhage

a variety of hemostatic disorders develop in association with neoplasia in animals and may result in disseminated intravascular coagulation and hemorrhage. Called also cancer-associated hemorrhage.

peritoneal hemorrhage

see hemoperitoneum.

petechial hemorrhage

subcutaneous hemorrhage occurring in minute spots.

postpartum hemorrhage

that which follows soon after parturition.

primary hemorrhage

that which soon follows an injury.

secondary hemorrhage

that which follows an injury after a considerable lapse of time.

subcutaneous hemorrhage

causes a soft, painless fluctuating swelling capable of being moved easily. Paracentesis reveals the presence of whole blood.
