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

Critically, they found that there was no significant difference in rates of lesion progression between the placebo group and the rFVIIa group, at any dose. In each section, the nuclei are stained with 4,6-diaminophenylindole DAPI blueand the secondary antibody used to detect the transcription factor is labeled with Cy3 redso that nuclear localization is indicated by pink nuclei. Routinely repeated computed tomography after blunt head trauma: Historically, HPC has been attributed to continued bleeding of microvessels fractured at the time of primary injury.

From the foregoing, it is evident that a contusion on the admission CT scan should be a cause for vigilance regarding possible HPC. For delayed hemorrhage to occur, either microvessels must have been fractured at the time of impact, even though they showed no evidence of bleeding initially, or microvessels not fractured at the time of impact must finally be opened, hours after the impact, contudion allow extravasation of blood.


Ninety-five minutes after the onset of neurologic deficits, the patient was given a bolus dose and 1-hour infusion of tissue plasminogen activator.

The aforementioned meta-analysis of 34 studies by Harhangi and associates Harhangi et al. Contusions occur primarily in the cortical tissue, especially under the site of impact or in areas of the brain located near sharp ridges on the inside of the skull. Numerous signaling pathways involving integrins, ion channels, and transcription factors contribute to this mechanosensitivity.

Upregulation of Sur1 with expression of the Sur1-regulated NC Ca-ATP channel also occurs following ischemia, but in this case, the transcriptional mechanism involves hypoxia inducible factor-1 Hif-1 working via Sp1 Simard et al.

D ICD – Acute coagulopathy in isolated blunt traumatic brain injury. Hence on follow-up CT scans in the first couple of days after trauma, ceregral may detect the increase in number and size of the lesions but the patient may not show any clinical deterioration. The genesis and significance of delayed traumatic intracerebral hematoma.

Inflammation mediates varying effects in neurogenesis: Conclusion Functional outcome after TBI is determined largely by the location of the cerebral injury and by the final volume of irreversible tissue damage sustained.

Additionally, Allard and associates Allard et al.

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

Also, there was cwrebral trend toward increased serious thromboembolic events in patients who received rFVIIa. However, mechanosensitive Sp1 upregulates transcription of Sur1 and of another cell death protein, caspase-3, in neurons but not in microvessels.

They may also have difficulty with memory, vision, speech, hearing, managing emotions, and thinking. This concept has given rise to the notion that continued bleeding might be due to overt or latent coagulopathy, prompting attempts to normalize coagulation with agents such as recombinant factor Hemirragica.

This study reinforced the early observations of Gudeman and associates Gudeman et al. Allard and associates Allard et al.
