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.

Subdural hematomas and find a common variant of the brain. Subarachnoid hemorrhage about the spaces surrounding the layers of subdural hematoma dating.
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.

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. A rough attempt was made to determine the effect of haematoma volume on attenuation and was found out to be statistically insignificant. The density of the subdural haematoma decreases with increase in the post-traumatic interval that concurs with the limited number of studies being conducted in the past.

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.

Study record managers: refer to the Data Element Definitions if submitting registration or results information. This study seeks to assess the safety and efficacy of middle meningeal artery embolization for chronic subdural hematoma in addition to standard treatments, which include close observation and surgical evacuation. Middle meningeal artery embolization has emerged recently as a minimally invasive and successful method of preventing re-accumulation of subdural hematoma, particularly for patients that are not obvious surgical candidates or those with recurrent or refractory hematomas.
The outcomes of these two groups of patients who undergo middle meningeal artery embolization will be compared to matched historical controls.

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. Most subdural hemorrhages results from trauma to the head.
The trauma damages tiny veins within the meninges. In young, healthy people, bleeding usually is triggered by a significant impact. This type of impact might occur in a high-speed motor vehicle accident. In contrast, older people may bleed after only a minor trauma. For example, it might happen from falling out of a chair. An acute subdural hemorrhage is bleeding that develops shortly after a serious blow to the head.
Dare to date: age estimation of subdural hematomas, literature, and case analysis.
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.

In the neonate, infant, or young child who has suffered from non-accidental injury, abusive head trauma AHT is acknowledged as the most common cause of fatality and long term morbidity with approximately 1, fatalities and 18, seriously disabled infants and children annually in the USA. Beyond the tragedy of an injured or murdered child is the broader social and community impact of this national and international health blight. In addition to the emotional, family, and social costs caused by inflicted trauma, the societal financial burden is astounding.
Subdural hemorrhage SDH is the most common pathology associated with abusive head trauma. Hemorrhage in this location conforms to the classic morphology of subdural bleeding concavoconvex. The authors also point out that in the first two years of life, the inner dural border zone plays an important role in the resorption of CSF as the arachnoid granulations are maturing.
More recently, Julie Mack and colleagues have advanced our understanding of a more dynamic vascularized dura. Of course, from the brain CT or MRI examinations which depict intracranial hemorrhage the intent behind trauma cannot be inferred. It is only after a comprehensive child protection team evaluation that the determination of abusive versus accidental or non-traumatic causes of hemorrhage is determined.
The goals for the medical imaging physician who is responsible for interpreting brain CT and MRI examinations for the pediatric patient with suspected abusive head trauma are clearly defined. These include: the determination of findings that require urgent and emergent treatment, fully assessing the extent of injury, estimating the timing of injury, detecting intracranial injuries in abused children who present with clinical manifestations of extracranial injury, and detecting mimics of SDH and underlying conditions which predispose to non-traumatic SDH.
CT is the examination of choice in the initial evaluation of pediatric head trauma. Its availability, rapid examination times, and sensitivity for detecting intracranial hemorrhage, early herniation patterns, and fractures make it an indispensible tool.
