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.

Histological dating of subdural hematoma in infants
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.
Chronic subdural hematoma (CSDH) is prevalent among elderly populations worldwide, and its mysterious pathogenesis has been discussed in the literature for.
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. Polytrauma, status of conscious level at admission, anemia, thickness of hematoma, and necessity for endotracheal intubation were enrolled.
The hypoxia and lower Glasgow coma scale at admission were found to be significant predictors of mortality. Conclusion Traumatic acute subdural hematoma still has a high mortality rate despite all developments in neurosurgical interventions.
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.

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. A year-old man presented with headache and vomiting of two weeks duration and weakness of the left upper and lower limb since five days.
He was addicted to alcohol for the past 20 years and had last consumed alcohol 10 days prior to admission. On examination he was in altered sensorium, not responding to verbal stimuli and had a dense left hemiplegia.
The Role of the Iron Stain in Assessing Intracranial Hemorrhage
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.

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.
Subdural Hemorrhage in Abusive Head Trauma: Imaging Challenges and Controversies
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.
Immediate symptoms of a subdural hematoma may be entirely absent and may for later reference, should questions arise about aging and dating of the lesion.
