Middle Meningeal Artery Embolization for Chronic Subdural Hematoma
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.

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.
Occasionally spontaneous acute subdural hematomas are seen with an underlying bleeding disorder e. A history of head trauma is often absent or very minor. Subdural hemorrhages are believed to be due to stretching and tearing of bridging cortical veins as they cross the subdural space to drain into an adjacent dural sinus. These veins rupture due to shearing forces when there is a sudden change in the velocity of the head.

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.

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

Chronic subdural hematoma (CSDH) is defined as a cystic unclotted hematoma with the outer and inner membranes in the subdural space. A common disease in.
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.
The Role of the Iron Stain in Assessing Intracranial Hemorrhage
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.

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. Prompt medical assistance is the single best predictor of recovery from any head injury, including subdural hematomas. Without proper medical intervention, death can occur in just a few hours. A subdural hematoma occurs when the tiny blood vessels within the brain’s dura tear, causing blood to pool in the brain.
The bleeding can quickly fill the brain, compressing parts of the brain, impeding brain function, leading to organ failure, and even causing death. Doctors have identified two types of subdural hematomas.

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.

Metrics details. A large craniotomy is usually the first choice for removal of traumatic acute subdural hematoma TASDH. To date, few studies have reported that TASDH could be successfully treated by twist drill craniostomy TDC alone or combined with instillation of urokinase. A total of 7 TASDH patients, who were presented and treated by TDC in this retrospective study between January and May , consisted of 5 men and 2 women, ranging in age from 65 to 89 average, The results showed that the mean time interval from injury to TDC was The mean distance of midline shift was The preoperative GCS in all patients ranged from 4 to 13 median, 9.
The mean duration of the operation was There were no cases of acute rebleeding and intracranial infection after TDC. TASDH in the elderly could be safely and effectively treated by TDC alone or combined with instillation of urokinase, which was a possible alternative for the elderly. Traumatic acute subdural hematoma TASDH caused by fall in the elderly patients is growing with the aging populations.
Many neurosurgeons are hesitant in offering aggressive management for these patients, which poses a therapeutic dilemma. The security and effectiveness of twist drill craniostomy TDC have been confirmed in the treatment of chronic subdural hematoma [ 1 , 2 , 3 ]. TDC was usually chosen for saving valuable time in the patients with TASDH and cerebral herniation before evacuation of subdural hematoma via decompressive craniectomy.
