intracranial hemorrhage (redirected from Intracranial hemorrhages)

intracranial hemorrhage

n.

The escape of blood within the cranium due to the loss of integrity of vascular channels and frequently leading to formation of a hematoma.

a hemorrhage within the cranium.

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.

intracranial abscess

signs will vary depending on which parts of the brain are compressed and damaged. General signs include circling, rotation of the head and mental dullness. The CSF may contain inflammatory cells.

intracranial hemorrhage

in the form of localizing hematomas with localizing signs occur very rarely in animals. May be multiple petechiae in asphyxial newborn lambs.

intracranial pressure (ICP)

the pressure within the subarachnoidal fluid, which is present in the space between the skull and the brain. Intracranial pressure, like arterial blood pressure, can fluctuate markedly and quickly during straining to defecate. While signs of sustained increased intracranial pressure can be significant in the assessment of a patient with a neurological disorder, momentary increases in intracranial pressure are not in themselves necessarily detrimental.

intracranial tumors

cause an increase in intracranial pressure and localizing signs, depending on the location of the tumor and the structures that are compressed.
