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.
SDH can happen in any age group, is mainly due to head trauma and CT scans are usually sufficient to make the diagnosis. Prognosis varies widely depending on the size and chronicity of the hemorrhage. Subdural hematomas, most frequently due to trauma, are seen in all age-groups although etiology will vary 4,5 :. Acute subdural hemorrhages usually present in the setting of head trauma. This is especially the case in young patients, where they commonly co-exist with cerebral contusions.
A large craniotomy is usually the first choice for removal of traumatic acute subdural hematoma (TASDH). To date, few studies have reported.
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. In a chronic subdural collection, blood leaks from the veins slowly over time, or a fast hemorrhage is left to clear up on its own. A subdural hematoma is more common in older adults because of normal brain shrinkage that occurs with aging. This shrinkage stretches and weakens the bridging veins. These veins are more likely to break in older adults, even after a minor head injury.
Dating of Early Subdural Haematoma: A Correlative Clinico-Radiological Study
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. The dura mater is the outermost layer of the meninges. The meninges is the three-layer protective covering of the brain.

Chronic subdural hematoma CSDH is prevalent among elderly populations worldwide, and its mysterious pathogenesis has been discussed in the literature for decades. The issues remaining to be solved in regard to CSDH include the initiating events; the bleeding into the subdural space and the formation of the outer and inner membranes, its development; increase and liquefaction of hematoma, the optimal treatments, and the natural history. The pathophysiology is becoming more clear due to recent findings from computed tomography studies and human models of CSDH.
In this work, we review previous studies on CSDH and present a new integrated concept about the development of this common condition after head injuries. Already have an account? Login in here. Journal of Medical and Dental Sciences. Journal home Journal issue About the journal.
Subdural hematoma, subarachnoid hemorrhage and intracerebral parenchymal hemorrhage secondary to cerebral sinovenous thrombosis: A rare combination. Department of Neurology, St. Cortical vein thrombosis CVT is increasingly recognized as a distinctive cause of cerebrovascular disease in the young. The easy availability of imaging techniques like magnetic resonance imaging MRI and venography MRV has led to better awareness among the neurologists.
Subdural hematomas undergo a similar course of decreasing density with time. Traditionally, a hyperdense subdural hematoma is thought to occur in the first.
A subdural hematoma SDH is a type of bleeding in which a collection of blood —usually associated with a traumatic brain injury —gathers between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. It usually results from tears in bridging veins that cross the subdural space. Subdural hematomas may cause an increase in the pressure inside the skull , which in turn can cause compression of and damage to delicate brain tissue.
Acute subdural hematomas are often life-threatening. Chronic subdural hematomas have a better prognosis if properly managed. In contrast, epidural hematomas are usually caused by tears in arteries , resulting in a build-up of blood between the dura mater and the skull. The third type of brain hemorrhage, known as a subarachnoid hemorrhage , causes bleeding into the subarachnoid space between the arachnoid mater and the pia mater.
The symptoms of a subdural hematoma have a slower onset than those of epidural hematomas because the lower-pressure veins involved bleed more slowly than arteries.
Middle Meningeal Artery Embolization for Chronic Subdural Hematoma
The incidence of traumatic brain injuries is increasing globally, largely due to an increase in motor vehicle use in low-income and middle-income countries. Purpose The aim of study was to investigate the factors that modulate the prognosis of patients with traumatic acute subdural hematoma. All the data collected were statistically analyzed and the results were compared with the international results.
Our recommendations were based on that comparison. Results Mortality rate was
Date of Acceptance, Feb Date of Web Publication, 3-Jun Conclusion Traumatic acute subdural hematoma still has a high mortality rate despite.
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. This study was conducted for dating the early subdural haemorrhage by routine histopathological stains. 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. Correlation between the frequency of a given histomorphological phenomenon and the length of the Post-Traumatic Interval PTI was evidential. All the histomorphological features, when correlated with PTI groups, were found to be statistically significant, except for Polymorphonuclear Leukocytes PMN.
We concluded that routine histopathology was reliable in the dating of early subdural haemorrhages. Road traffic accidents take about 1.
