Management and Outcome of Acute Subdural Hematoma in Gabriel TouréHospital

Background: Traumatic Brain Injury (TBI) is a major health problem worldwide. It is the main cause of trauma mortality. Acute subdural hematoma (ASDH) has a reputation for being the most serious of all posttraumatic head injuries. Its frequency is estimated to be 1% to 5% of all head injuries and 22% of severe head injuries. The aim of this study was to assess the epidemiological, clinical and prognosis aspects of ASDH in our department. Material and Methods: This prospective study, from January to December 2019, included 57 patients admitted to the Gabriel Touré Teaching Hospital for ASDH. Patients underwent detailed clinical and radiological evaluation and ASDH was diagnosed by non-contrast computed tomography (CT) scan. Functional outcome was evaluated 6 months after injury by Glasgow Outcome Scale. Results: During the study period, 662 patients were admitted for TBI including 57 (8.61%) cases of ASDH. The mean age was 34 years with extremes of 2 and 77 years. There was a male predominance with 52 (91.2%). The main cause of trauma was motor vehicle accidents in 38 (66.6%) patients. According to the Glasgow coma scale (GCS), 33 (57.9%) patients were classified mild (Table 2). The thickness of the hematoma was more than 1 cm in 13 (22.8%) patients and less than 1 cm in 44 (77%) patients. Surgical treatment was performed in 13 (22.8%) patients. The outcome was favorable in 30 (52.6%) patients and the mortality rate was 33.3%. Conclusion: ASDH remains a difficult challenge because of the high mortality. The mortality rate remains high particularly in patient with poor GCS score at admission.

Usage of neuronavigation system to treat a case of traumatic acute subdural hematoma after two-side ventriculoperitoneal shunt

Traumatic acute subdural hematoma is one of the most lethal causes of head injuries,which leads to high mortality.While combined diseases always make it more intractable for the treatment.We present a case of a 68-year-old female patient with traumatic acute subdural hematoma combined with hydrocephalus after ventriculoperitoneal shunt assisted by the neuronavigation system in January 12,2017.She was undergone ventriculoperitoneal shunt 6 years and 5 months ago on two sides respectively because of hydrocephalus,with the ventriculoperitoneal shunt device on the right side out of work.The initial neurological examination showed a Glasgow Coma Scale of E2V1M5 with no papillary defect.A CT scan of the head revealed a left homogeneously hyperdense and subdural hematoma,with compression of the lateral ventricle(2.6 cm thick)and a 0.5 cm midline shift.To protect the ventriculoperitoneal shunt device,we used neuronavigation system to precisely mark the relative location of the device and“invisible”subdural hematoma,thus to design a perfect incision preoperatively.Subsequently,evacuation of the subdural hematoma was performed via craniotomy without damaging the ventriculoperitoneal shunt device.Postoperative CT of the head showed totally removing of the subdural hematoma.The patient recovered three months later.With the assistant of neuronavigation system,it is much easier for the preoperative planning and to reduce the surgical risk.Our case gives a clue that more approaches can be considered when encountering acute head trauma with the complicated combined diseases.

Fatal deterioration of delayed acute subdural hematoma after mild traumatic brain injury： two cases with brief review

Both delayed posttraumatic intracerebral hemorrhage and epidural hematoma have been well described in the neurosurgical literatures. However, delayed posttraumatic acute subdural hematoma which happens more than a week with a rapid progress after mild traumatic brain injury and causes death of patient is rarely reported. We show two such cases and briefly review the literature and discuss the probable pathogenesis of their rapid progress.

Acute subdural hematoma with swirl signs： clinical analysis of 15 cases

From July 2003 to July 2009, 15 cases of subdural hematoma with swirl signs were treated in our hospital and their clinical data were retrospectively analysed. The mortality was compared between these patients and those with typical acute subdural hematoma who were treated at the same time in our hospital. Among the 15 cases, full recovery was achieved in 4 cases, slight disability in 2, grave disability in 2 and death in 7 （46.7%）. The mortality of these patients was conspicuously higher than that of typical sub- dural hematoma （14/83, 16.9%, P〈0.01）. Subdural hematoma with swirl signs is often suggestive of hazardous pathogenetic condition and early diagnosis and prompt surgical intervention is essential to reduce mortality.

Enigmatic rapid organization of subdural hematoma in a patient with epilepsy:A case report

BACKGROUND Determining a subdural hematoma(SDH)to be chronic by definition takes 3 wk,whereas organized chronic SDH(OCSDH)is an unusual condition that is believed to form over a much longer period of time,which generally demands large craniotomy.Therefore,it is a lengthy process from the initial head trauma,if any,to the formation of an OCSDH.Acute SDH(ASDH)with organization-like,membranaceous appearances has never been reported.CASE SUMMARY A 56-year-old woman presented to our hospital with a seizure,and computed tomography(CT)on admission was negative for signs of intracranial hemorrhage.She had clear consciousness and unimpaired motor functions on arrival and remained stable for the following week,during which she underwent necessary examinations.On the morning of day 10 of hospitalization,she accidentally hit her head hard against the wall in the bathroom and promptly lapsed into complete coma within 2 h.Therefore,we performed emergency CT and identified a left supratentorial SDH that was an absolute indication for surgery.However,the intraoperative findings were surprising,with no liquefaction observed.Instead,a solid hematoma covered with a thick membrane was noted that strongly resembled an organized hematoma.Evacuation was successful,but the family stopped treatment the next day due to financial problems,and the patient soon died.CONCLUSION Neurosurgeons should address SDHs,especially ASDHs,with discretion and individualization due to their highly diversified features.
