Acute subdural hematoma is usually a neurological emergency that requires hematoma evacuation or close observation. However, spontaneous resolutions of an acute subdural hematoma without surgical interventions have been reported rarely. We report on a case who showed rapid resolution of an acute subdural hematoma with neurological improvement and review the relevant literatures.

We experienced 2 cases of caute subdural hematoma with tentorial herniation due to ruptured posterior communicating artery aneurysm. Based on a review of the literature and the clinical course in the present cases, recommend therapy consist of early evacuation of hematoma and clipping of aneurysm because of the not infrequent development of rapid deterioration.

A case of traumatic acute bilateral subdural hematoma with different times is expierenced. The contralateral shbural hematoma was developed during the evacuation of an acute subdural hematoma. The reduction of intracranial pressure after removal of subdural hematoma was postulated to be contributing factor to formation of the contralateral subdural hematoma.

The authors reported 100 cases of acute subdural hematomas confirmed by operation from Jan. 1972 to Sept. 1975. We discussed the relationship of the type of operation to mortality in acute subdural hematomas. The types of surgical operations were divided in 4 groups. The surgical mortality rate was 19% for frontotemporoparietal craniotomy, 29% for multiple burr holes technique, 42% for craniectomy and 48% for subtemporal decompression with burr holes and total over-all mortality was 36% in our cases. The authors reviewed the literatures described the surgical operative method and it's mortality and so we thought large frontotemporoparietal craniotomy is more valuable method for operation of the acute subdural hematomas.

Decompressive craniectomy is usually performed to relieve raised intracranial pressure(ICP) caused by various intracranial lesions. A 67-year-old man presented with acute subdural hematoma and traumatic intracerebral hematoma. The patient underwent a decompressive craniectomy. Four weeks later, the patient presented with acute neurological deterioration. Brain computed tomographic(CT) scans revealed the marked concavity of the brain at the site of the craniectomy and associated with midline shift which was reversed by cranioplasty. We report an unusual case of cerebral herniation from intracranial hypotension after decompressive craniectomy for a traumatic subdural hematoma. The cranioplasty may be helpful to prevent paradoxial cerebral herniation.

We present a series of 183 operated acute(within 24 hours) subdural hematomas from 1985 to 1991. All were diagnosed by computerized tomography. The primary causes of acute subdural hematoma were passenger's traffic accident(36.6%), pedestrian accident(31.7%), fall or slip(16.4%), and assaults(2.7%). A favorable outcome(good recovery and moderate disability) occurred in 31.7%, an unfavorable outcome(severe disability and vegetative state) in 11.5%, and a death resulted in 56.8% at discharge. Preoperative Glasgow Coma Scale score(GCS) and papillary status were major clinical predictors of prognosis. Age, sex, operative timing, severity of associated extracranial injury, and blood pressure on arrival did not significantly affect on the prognosis. As radiological predictors, degree of midline-shift, presence or absence of skull fracture, status of perimesencephalic cistern or third ventricle were significantly correlated with outcome. Size of the hematoma and presence or absence of combined intracranial focal lesions did not reflect a significant difference in the outcome.

Complications after surgery for chronic subdural hematoma (SDH) include recurrence of the hematoma, tension pneumoencephalus and intracerebral hematoma. We report an unusual case of development bilateral of acute subdural hematoma after drainage of chronic subdural hematoma in a 48-year-old woman. Pathophysiological mechanisms of this uncommon entity are discussed and relevant literature is reviewed.

A propecive analysis of 50 patients with acute interhemisphric subdural hemorrhage and tentorial hemorrhage, an unusual pattern of acute subdural hematoma, who were managed in a uniform way was analyzed to related outcome to hemorrhagic site, initial Glasgow Coma Scale(GCS) and combined injuries. The incidence of acute interhemisphric subdural hemorrhage(ISH) and tentoria hemorrhage(TH) after head trauma was 3.83%, 50 cases among 1303 head injured cases. And 80% of the above hemorrhage disapperaed within two weeks after trauma. There was no significant relationship between feature of hemorrhage and intial GCS(P>0.05), but there was highly significant relationship between initial GCS and Glasgow Outcome Scale(GOS) (p<0.001). There noted significant relationship between initial combined injury and GOS(p<0.01), and also brainstem injury and GOS(p<0.001).
