The distinction between contusion and intracerebral hemorrhage is blurry because both involve bleeding within the brain tissue; however, an arbitrary cutoff exists that the injury is a contusion if two thirds or less of the tissue involved is blood and a hemorrhage otherwise. Morgan Hill, New York. Routinely repeated computed tomography after blunt head trauma: Check for errors and try again.

Delayed traumatic intracerebral hematoma: Neurotrauma S06, Sx4, T The hemorrxgica shown are of the penumbra outside the initial contusion. A year-old woman with chronic atrial fibrillation was admitted for an elective exchange of an implanted defibrillator for idiopathic dilated cardiomyopathy.

Inside the neutrophil phagosome: In this review, we begin by documenting the characteristic features of HPC. Sindrome hiponatremico natriuretico asociado a contusion cerebral hemorragica: The patient has had no further neurologic symptoms, with no measurable deficit.

Case 4 Case 4. Typical causes include motor vehicle accidents or situations in which the head strikes the ground.

As noted above, coagulopathy by any measure is reported to occur with some variability upon admission Lustenberger et al. Case 9 Case 9. Implications for Clinical Neuropsychology. Key role of sulfonylurea receptor 1 in progressive secondary hemorrhage after brain contusion. TBI associated with cerebral contusion is a frequent cause of death and disability in trauma victims who reach the hospital alive Alahmadi et al. Hypoxia-sensitive transcription of Sur1 thus reinforces mechanosensitive transcription of Sur1.

Prognostic value of admission laboratory parameters in traumatic brain injury: Early administration of a thrombolytic agent is essential for optimal neurologic recovery.

Traumatic middle cerebral artery aneurysm: A hemorrhagic contusion on CT scan demarcates tissues with essentially total, unrecoverable loss of function.

Dissecting Aneurysm of the Posterior Cerebral Artery. Coagulopathy in traumatic brain injury. In animal models of contusive TBI, HPC or progressive secondary hemorrhage is blocked by administering antisense oligodeoxynucleotide directed against Abcc8the gene that encodes Sur1 Simard et al.


Hemorrhagic Progression of a Contusion after Traumatic Brain Injury: A Review

When head trauma results in a contusion, the hemorrhagic lesion often expands or a new hemorrhagic lesion may develop remotely non-contiguously from the original contusion during the first several hours after impact Fig.

Before the procedure was performed, acute-onset right hemiparesis and expressive dysphasia developed.

In the TBI literature, coagulopathy is often broadly defined as any perturbation in a patient’s coagulation parameters, and may include a prolongation of the prothrombin time PTan elevation of the International Normalized Ratio INRan elevation of the activated partial thromboplastin time aPTTor a decrease in the platelet PLT count Engstrom et al.

The aforementioned meta-analysis of 34 studies by Harhangi hejorragica associates Harhangi et al.

They also found that while small hemorrhagic lesions may expand, lesions that were larger at baseline tended to have substantially greater increases, with an associated greater likelihood of clinical impact. Breakdown products of extravasated blood are extremely toxic to central nervous system CNS cells and also incite secondary injury responses.
