Dating of Acute and Subacute Subdural Haemorrhage: A Histo-Pathological Study

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 The mean and SD of age in our study was The range of age was 64 years 21—85 years. The entire study population was subjected to logistic regression analysis, severity of injury, presence of a secondary injury especially hypoxia or both hypoxia and hypotension.

Subdural hematomas undergo a similar course of decreasing density with time. Traditionally, a hyperdense subdural hematoma is thought to occur in the first.

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.

Histological dating of subdural hematoma in infants

A subdural hematoma is a serious, and potentially life-threatening, head injury that occurs when blood collects between the brain’s cover known as the dura and its surface. A subdural hematoma is not something you can diagnose at home, though you may suspect you have one based on symptoms. Any head injury is a medical emergency that has the potential to become life-threatening.

So if you have recently suffered a blow to the head, have signs of a stroke, or have experienced a change in consciousness or personality, don’t delay seeking medical help.

Attempts to date contusions, however, have generally been unsuccessful by Fig. (2). Prussian blue stain of an acute subdural hematoma in a 51 year old man.

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. We concluded that further sorting of cases could be done according to its age with additional research and uniformity in the methodology.

Subdural Haemorrhage SDH is a form of brain haemorrhage in which there is a collection of blood between the dura and the arachnoid layers of the meninges. It is usually associated with mechanical brain injury [ 1 ]. The occurrence of subdural haemorrhage may or may not be associated with any visible injury to scalp, skull or brain. Hence, radio imaging tools remain the only method to diagnose subdural haemorrhage and its characteristics in surviving patients [ 2 ]. In the hyperacute phase, they appear relatively iso-dense to the adjacent cortex, with a swirled appearance due to a mixture of a clot, serum, and ongoing unclotted blood.

In the acute phase, SDH appears as a hyper-attenuated crescent-shaped extra-axial collection.

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.

Bilateral subdural hematomas were, in our series, of the same density on both sides in all patients. Information on the date of previous trauma or beginning of.

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.

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. Middle meningeal artery embolization is a minimally invasive angiography procedure completed with use of fluoroscopy.

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.

The clinical picture is extremely variable and presentation is often misleading. We report a case of CVT with hemorrhages in three brain compartments – subdural, subarachnoid and parenchymal. Occurrence of both intracranial bleeding and thrombosis makes the management of such a patient challenging.

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.

Dare to date: age estimation of subdural hematomas, literature, and case analysis.

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.

What Causes a Subdural Hematoma? Any head injury, including relatively minor injuries, can lead to subdural hematomas, since such bleeding only requires.
