hemorrhage

 [hem´ŏ-rij]
the escape of blood from a ruptured vessel; it can be either external or internal. 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. Aside from the obvious flow of blood from a wound or body orifice, massive hemorrhage can be detected by other signs, such as restlessness, cold and clammy skin, thirst, increased and thready pulse, rapid and shallow respirations, and a drop in blood pressure. If the hemorrhage continues unchecked, the patient may complain of visual disturbances, ringing in the ears, or extreme weakness.
capillary hemorrhage oozing of blood from minute vessels.
cerebral hemorrhage a hemorrhage into the cerebrum; one of the three main causes of cerebral vascular accident (stroke syndrome).
concealed hemorrhage internal hemorrhage.
fibrinolytic hemorrhage that due to abnormalities of fibrinolysis and not hypofibrinogenemia.
internal hemorrhage that in which the extravasated blood remains within the body.
intracranial hemorrhage bleeding within the cranium, which may be extradural, subdural, subarachnoid, or cerebral.
petechial hemorrhage subcutaneous hemorrhage occurring in minute spots.
postpartum hemorrhage that which follows soon after labor.
primary hemorrhage that which soon follows an injury.
secondary hemorrhage that which follows an injury after a considerable lapse of time.

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
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
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
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

within the cranium.

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.

He pointed out that overall, the three novel oral anticoagulants--dabigatran and the factor Xa inhibitors, apixaban and rivaroxaban--approved for the nonvalvular AF indication, appear to reduce the risk of stroke and death, "and across the board, they all show significantly less intracranial hemorrhage.
Common injuries for these patients included head/neck soft tissue injuries, femur fractures, concussions, and intracranial hemorrhages (Table 1).

Adverse events in the study included intracranial hemorrhage, or bleeding in the brain, in one patient, and myocardial infarction 11 months after surgery.

Omae and colleagues (3) in Japan, for example, studied 73 patients (autopsies in 62) who died within 24 hours of the first onset of symptoms, and intracranial hemorrhage, comprising both subarachnoid and ICH, was the cause in 38 (53%).
com)-- A study of patients diagnosed with acute ischemic stroke who received intravenous thrombolysis showed that more rapid treatment reduced the rate of in-hospital deaths and symptomatic intracranial hemorrhage and increased the rate of patients who were walking independently at discharge or discharged to home.
Also, symptoms often mimic those of neoplasms because of local mass effects (producing sensory and motor deficits and/or seizures) and are occasionally secondary to intracranial hemorrhage.
Nontraumatic intracranial hemorrhage, spinal dysraphisms, brain tumor, epilepsy, and interventional radiology's management of vascular abnormalities are also addressed.
