Subarachnoid hemorrhage and find a subdural hematoma is a date of her head trauma aht cases.
The timing of the breakdown of red blood cells and organization of hemorrhage has significance in the catabolism of heme and the processing of iron, but also has a practical application in terms of assigning, or attempting to assign, a time course with respect to traumatic events e. Attempts to date contusions, however, have generally been unsuccessful by macroscopic observation, whereas the microscopic observations provide broad data but are also anatomically imprecise as a function of time.
Intracranial lesions are of particular significance with respect to the timing of organizing hemorrhage given the acute, and often life-threatening nature of the hemorrhages, and the medicolegal investigation into potential crimes. Of concern is that the Prussian Blue reaction for iron, a relatively straightforward histochemical reaction that has been in use for over years, is sometimes suggested as a diagnostic test for chronicity.
Therefore, this study examined the utility of the Prussian Blue iron stain in living patients with intracranial hemorrhages and well-defined symptom onset, to test whether the presence of Prussian Blue reactivity could be correlated with chronicity. It was found that out of 12 cases with intracranial hemorrhage, eight cases showed at least focal iron reactivity.
Chronic subdural hematoma (CSDH) is prevalent among elderly populations worldwide, and its mysterious pathogenesis has been discussed in the literature for.
Study record managers: refer to the Data Element Definitions if submitting registration or results information. Traumatic acute subdural haematomas ASDHs are common pathological entity in neurosurgical practice. Approximately two -thirds of patient with TBI undergoing emergency cranial surgery have an acute subdural haematoma evacuated. Two common causes of traumatic ASDH: accumulation of blood around parenchymal laceration , usually frontal and temporal lobes and there is usually severe underlying brain injury.
The second cause is surface or bridging vessel torn from cerebral acceleration – deceleration during violent head motion. This high mortality rate has been attributed to the characteristic of haematoma itself , due to the primary insults to the brain like brain parenchymal injury , and to the secondary insults like hypoxia and hypotension in severe head injury patients. Theoretically ,intracranial hypertension due to ASDH may lead to transtentorial cerebral herniation and secondary ischemic injury of the brain.
The criteria used to select patients for non – operative management are clinical stability or improvement during the time from injury to evaluation at hospital , haematoma thickness less than 10 mm and mid line shift less than 5 mm in the initial CT. Time of surgery for ASDH is matter of controversy. As general principle ,when surgery for ASDH is indicated it should be done as soon as possible. Regarding evacuation of acute subdural haematoma, procedures vary from single burrhole evacuation to craniotomies and decompressive procedures.
Dating of Early Subdural Haematoma: A Correlative Clinico-Radiological Study.
Imaging CT findings in cases of subdural hematoma after cardiovascular surgery. Initial signs of SDH. A characteristic initial sign of CT findings, as seen in cases of subdural hematoma SDH after cardiovascular surgery, was reported. Central-nervous-system CNS complications after cardiovascular surgery have been thought to be due mainly to the ischemic brain damage caused by both reduced cerebral perfusion pressure and microembolism during extracorporeal circulation.
However, we observed 8 cases of SDH in 39 patients suffering from major CNS complications after cardiovascular surgery. In view of these experiences, SDH was thought to be one of the most significant factors causing CNS complications after cardiovascular surgery.

Dating of Acute and Subacute Subdural Haemorrhage: A Histo-Pathological Study.
Determination of post-traumatic interval remains one of the foremost important goals of any forensic investigation related to human crimes. The estimation of time since injury in cases of subdural haemorrhage has been studied only by a few investigators on the histological and radiological front. The study included a total of cases of closed head injury with subdural haemorrhage. Statistically significant results were obtained between the HU measurements of the SDH and the post-traumatic intervals and were found to be statistically significant.
The purpose of this study was to determine the post-traumatic interval of Subdural Haemorrhage (SDH) based on Hounsfield Unit measurements.

Dating of Early Subdural Haematoma: A Correlative Clinico-Radiological Study
A chronic subdural hematoma is an “old” collection of blood and blood breakdown products between the surface of the brain and its outermost covering the dura. The chronic phase of a subdural hematoma begins several weeks after the first bleeding. A subdural hematoma develops when bridging veins tear and leak blood. These are the tiny veins that run between the dura and surface of the brain.
This is usually the result of a head injury. A collection of blood then forms over the surface of the brain.
were dated by history, when available. Hematomas were grouped as follows: acute, four; early subacute, four late subacute, four; chronic, Six collections.
After infant deaths due to non-accidental head injury NAHI with subdural hematoma SDH , the magistrates ask experts to date the traumatic event. To do so, the expert only has tools based on adult series of NAHI. Two pathologists assessed blindly and independently 12 histomorphological criteria relating to the clot and 14 relating to the dura mater in 73 victims 31 girls, 42 boys whose median age was 3.
Histopathological changes were significantly correlated with PTI for the appearance of red blood cells RBCs and the presence or absence of siderophages, and regarding the dura mater, the quantity of lymphocytes, macrophages, and siderophages; presence or absence of hematoidin deposits; collagen and fibroblast formation; neomembrane thickness; and presence or absence of neovascularization.
Dating systems for SDH in adults are not applicable to infants. Notably, neomembrane of organized connective tissue is formed earlier in infants than in adults. Our dating system improves the precision and reliability of forensic pathological expert examination of NAHI, particularly for age estimation of SDH in infants.
However, the expert can only define a time interval. Histopathology is indispensable to detect repetitive trauma.
Diffusion-Weighted MR Imaging of Intracerebral Hemorrhage
If the haematoma was present in more than one slice, then the average HU bleed of all those slices were taken as mentioned above. The HU measurements radiopaedia measured away from the rim of the mass haemorrhage to avoid partial volume effect. To assess intra-reader reliability, each reader repeated HU measurements thrice in an individual case with an interval of three weeks between each hyperdense.
Moreover, analysis of subdural hematoma density in abusive head trauma often reveals a combination of multiple subdural hematomas with different attenuation. [.

Jul, Vol. Abstract: Introduction: Microscopic study of the organization of the Subdural Haemorrhage SDH verified against the time period can help us in the determination of its age which has serious medico-legal implications.
Very few studies concerning the dating of SDH are present in the literature. Aim: This study was conducted for dating the early subdural haemorrhage by routine histopathological stains. Materials and Methods: A prospective analytical study was conducted during July to December A total of cases 50 males and 50 females fulfilling the inclusion and exclusion criteria were included in this study.
Routine histopathological staining of the subdural haematoma was done. Results: Correlation between the frequency of a given histomorphological phenomenon and the length of the Post-Traumatic Interval PTI was evidential.
Chronic subdural hematoma
A subdural hematoma occurs when a blood vessel near the surface of the brain bursts. Blood builds up between the brain and the brain’s tough outer lining. The condition is also called a subdural hemorrhage. In a subdural hematoma, blood collects immediately beneath the dura mater.
BackgroundAfter infant deaths due to non-accidental head injury (NAHI) with subdural hematoma (SDH), the magistrates ask experts to date the traumatic event.
The 42 patients with the available data were then subdivided into three groups; acute, subacute, and chronic, according to the time interval between trauma or duration of symptoms and date of CT scanning.
