Abstract
A subdural haematoma is a collection of blood in the space between the outer layer (dura) and middle layer of the covering of the brain in the subdural space between the dural and arachnoidal layers of the meninges.(1)
ASDH is one of the conditions most strongly associated with severe brain injury.(18)
There are three types of SDH: Acute: develops within 48 hours of an injury to the head. Subacute: develops more than 48 hours but less than two weeks of an injury to the head. Chronic: develops more than two weeks after an injury to the head.(12)
The diagnosis of SDH is definitively established with neuroimaging of the brain—either with CT scan or MRI.(43)
Emergent surgical evacuation is recommended in the vast majority of the ASDH cases and definitely in those greater than 10mm in thickness.(62)
ASDHs larger than 10mm in thickness or associated with deteriorating level of consciousness, pupillary changes, or hemiparesis generally require immediate surgical intervention.(64)
Prognosis in ASDH is associated with age, etiology, time from injury to treatment, presence of pupillary abnormalities, GCS on admission, immediate coma or lucid interval, CT scan findings (haematoma volume, degree of midline shift, associated intradural lesion, compression of basal cisterns), post-operative intracranial pressure and type of surgery.(72)
Traumatic ASDH continues to have high morbidity and mortality despite the advent of rapid transportation, CT scanning, ICP monitoring and intensive care management.(21,70)
The present study was designed to assess the effect of age, gender, mode of trauma, duration from trauma till treatment, GCS, midline shift and treatment modalities (conservative and surgical treatment) in the outcome of ATSDH.
This study was conducted on 21 cases of acute traumatic subdural hematoma were admitted at the emergency department and treated at the department of Neurosurgery, Alexandria Main University Hospital.
