Duret haemorrhages are named after Henri Duret, [2] who discovered these brainstem lesions in dogs with increased intracranial pressure. [3] They are small linear areas of bleeding in the midbrain and upper pons of the brainstem .
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]
A study of 66 dogs with Cushing's found 91% of dogs to have either polyuria or polydipsia, 79% to have polyphagia, and 77% to have alopecia. [ 4 ] Signs of ectopic adrenocorticotropic hormone secretion that accompany the rapidly progressing physical changes are high plasma levels of adrenocorticotropic hormones and cortisol alongside hypokalaemia .
Symptoms of chronic subdural hematomas are usually delayed more than three weeks after injury. [1] If the bleeds are large enough to put pressure on the brain, signs of increased intracranial pressure or brain damage will be present. [3] Other symptoms of subdural hematoma can include any combination of the following: [7]
Subarachnoid hemorrhage as shown on a CT scan. It is denoted by the arrow. This type of injury may result in damage to the brainstem, which could initiate or worsen the symptoms of the Cushing reflex. Whenever a Cushing reflex occurs, there is a high probability of death in seconds to minutes.
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 ...
Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.
