Posterior fossa subdural hematoma due to ruptured arteriovenous malformation

Case report

Narendra N. Datta, Kwong Y. Chan, John C. K. Kwok, and Christopher Y. F. Poon

Patients with cerebellar arteriovenous malformations (AVM) commonly present to the neurosurgical department after having suffered hemorrhages. The subarachnoid space is the usual location for these often repeating episodes of bleedings. In addition, these patients can present with parenchymal hemorrhage. Acute subdural hematoma caused by a ruptured cerebellar AVM is a rare entity and is not generally recognized. The authors present a case of acute posterior fossa subdural hematoma resulting from a ruptured cerebellar AVM.

Subdural hematoma as a major determinant of short-term outcomes in traumatic brain injury

the presence or absence of either a traumatic subarachnoid hemorrhage (tSAH) or intraventricular hemorrhage (IVH), but omits the Marshall system's feature of hemorrhagic mass volume. 26 Among specific subtypes of hemorrhage in TBI, acute subdural hematoma (SDH) has been associated with significant short-term mortality rates, which may range as high as 40%–90% depending on GCS score and age. 12 , 17 , 20 Even with prompt surgical evacuation, mortality rates remained as high as 42%. 20 Gennarelli et al. 11 reported that acute SDH had a higher mortality rate

Successful management of an acute subdural hematoma in a patient dependent on continuous treprostinil infusion therapy

resolution of midline shift. D: Three-month follow-up scan revealing continued evolution of the residual SDH. Operation and Findings A curvilinear incision was made and a large right frontotemporoparietal craniotomy was performed. The dura was opened and the subdural hematoma was removed using a combination of tumor forceps, suction, and irrigation. A pial vessel at the posterior aspect of the frontal lobe was bleeding briskly. This vessel was successfully coagulated with bipolar electrocautery. A subdural drain was placed, the bone flap was reapplied, and

Subdural hematoma in an adult following a blast injury

Case report

J. M. K. Murthy, J. S. Chopra, and D. R. Gulati

result in the production of large subdural hematoma and effusions. 2 We wish to report a case of subdural hematoma without skull fracture following a blast injury due to the explosion of a pipe. To the best of our knowledge such a case has not previously been reported. Case Report This 26-year-old man was a pipe fitter by occupation. He was admitted with the complaints of headache, vomiting, and slight blurring of vision in the right eye of 1 month's duration. There was no history of unconsciousness or convulsions. About 10 days before the start of the

Surgical options for treatment of traumatic subdural hematomas in children younger than 2 years of age

Clinical article

T he most common findings on cranial CT in pediatric victims of abusive head trauma (AHT) are subdural hematomas (SDHs), present in more than 70% of cases. 2 , 3 , 8 , 14 , 16 , 23 The SDHs are commonly bilateral and sometimes associated with interhemispheric hyperdensity and/or convexity hemorrhages. 3 , 7 , 8 , 30 The management options remain controversial and range from conservative clinical surveillance (nonsurgical management) to subdural punctures, external subdural drainage, subcutaneous reservoirs, subdural-subgaleal shunts, subdural

The implications of antithrombotic agents on subdural hematoma evacuation: what does "reversal" truly entail?

unclear when considering operative management. 9 , 10 , 15 Its use and safety specifically for subdural hematoma (SDH) evacuation have been insufficiently investigated in comparison with intraparenchymal hemorrhage. 16 Furthermore, reversal incurs its own risk of serious adverse events, including thrombosis, anaphylaxis, and potential delays in care. 9 , 12 , 15 , 17 At our institution, ATT reversal for neurosurgical trauma patients follows multidisciplinary institutional guidelines that direct the use of reversal agents for all patients with active ATT use and

Evaluation of the age of subdural hematomas by computerized tomography

Giuseppe Scotti, Karel Terbrugge, Denis Melançon, and Gary Bélanger

S ince the first report of Ambrose 1 suggesting a possible inaccuracy of computerized tomography (CT) in demonstrating subdural hematomas, further papers have modified this early impression. 2, 7, 10 There is general agreement among the authors that subdural hematomas may present on CT scan in at least three different forms: hematomas that have an attenuation coefficient higher than the surrounding brain (that is, in the range of 35 to 45 EMI units, hyperdense); hematomas of the same density as brain (14 to 24 EMI units, isodense); and hypodense hematomas (4

Fibrinolytic enzyme in the lining walls of chronic subdural hematoma

Haruhide Ito, Toshio Komai, and Shinjiro Yamamoto

V irchow regarded inflammation of the dura mater as the cause of chronic subdural hematoma, 11 while Gardner proposed an osmotic gradient theory. 5 However, the pathogenesis of chronic subdural hematoma is still under debate. The contents of most chronic subdural hematomas are liquid. Raised levels of fibrin and fibrinogen degradation products (FDP) in the hematoma contents 6, 7, 9 and continuous hemorrhage into the hematoma 7, 10, 13 have been demonstrated, and the presence of tissue activator in the outer membrane of the hematoma has been shown

Association of ossified subdural hematomas and a meningioma

Case report

Joseph F. Cusick and Orville T. Bailey

T he scanty literature on calcified and ossified subdural hematomas deals largely with roentgenographic findings and the clinical manifestations of seizures and mental disturbance. Of the 34 recorded cases, 3, 4 there is little mention of the anatomical extent of the hematomas or associated pathological conditions. We are reporting the findings in a patient with massive bilateral ossified hematomas intimately associated with a huge right frontotemporoparietal meningioma.
