This report describes a new method for the treatment of traumatic subdural effusion (TSE). Following Ommaya reservoir implantation, a patient with contralateral progressive TSE secondary to decompressive craniectomy after traumatic brain injury made a good postoperative recovery.

Endoscope-Assisted Keyhole Surgery for Traumatic Subacute Subdural Hematoma Evacuation in Emergencies.

OBJECTIVE: This study aimed to investigate whether a simple endoscopic method was effective for the evacuation of traumatic subacute subdural hematomas. METHODS: A total of 51 patients with subacute subdural hematomas requiring surgery were enrolled in this study. An endoscopic hematoma evacuation was performed through a small bone window for 22 patients. Hematoma evacuation by open surgery was performed for 29 patients. The postoperative Glasgow Coma Scale scores improvement, surgery times, displacement of midline measurements, and intraoperative blood loss were recorded and analyzed for each patient. RESULTS: The average time from the initial incision to suture completion was 38.41 ± 6.97 minutes for the endoscopic surgery group and 74.66 ± 9.54 minutes for the open-surgery group (P < 0.01). The average total blood loss was 41.36 ± 10.82 ml for the endoscopic group and 250.00 ± 58.25 ml for the open-surgery group (P < 0.01). No postoperative bleeding occurred in either group. The midline displacement measurement showed significant improvement on the day after surgery, with 5.21 ± 1.98 mm in the study group versus 6.75 ± 1.37 mm in the control group (P < 0.01). At the 1-month follow-up appointment, the midline measurement was normal in both groups. Computed tomography scans revealed almost no residual hematomas, representing an average evacuation rate of 100% in both groups. The average Glasgow Coma Scale scores improvement on the day after surgery were 1.77 ± 1.93 in the endoscopic surgery group and 1.66 ± 0.77 in the open-surgery group (P = 0.766). CONCLUSION: Endoscopic subacute subdural hematoma removal through a small bone window achieved satisfactory hematoma removal using a minimally invasive method when compared with an open-surgery method.

Bilateral extradural haematoma after acute ventricular over-drainage.

BACKGROUND: Ventricular over-drainage is a common complication of dysfunctional ventriculoperitoneal devices. Subdural haematomas are usually the most common lesions associated with that complication. Such lesions may arise after ventricular collapse and bridging veins disruption that follows over-drainage, thus contributing to distortion of brain parenchyma, increased intracranial hypertension and neurological decline. More rarely, extradural haematomas may also be observed after ventricular shunt hyperfunction and may result in rapid neurological decline unless a surgical procedure can be promptly performed. CASE: This study reports the case of a 38-old-woman who presented supratentorial hydrocephalus and developed bilateral extradural haematomas after the placement of a ventricular shunt device. Both haematomas were surgically approached and the dysfunctional shunt device was replaced. CONCLUSION: Extradural haematomas may develop precociously after ventricular over-drainage. Surgical treatment is mandatory and must include not only the evacuation of haematoma, but also the replacement of dysfunctional shunt to prevent further recurrence. The pathophysiology of extradural haematomas consequent of ventricular over-drainage and the possible use of a programmable valve to prevent these lesions are briefly discussed.

Temporary alopecia after embolization of an arteriovenous malformation.

Alopecia after head and neck radiotherapy has been extensively reported in the literature. However, alopecia after endovascular procedures is seldom reported in the dermatological literature. Prolonged fluoroscopic imaging during these procedures may cause serious radiation injuries to the skin, such as dermatitis or alopecia. Radiation-induced temporary alopecia is a peculiar form of radiodermitis that occurs over the areas of the scalp that receive the highest doses of radiation. Although repopulation of alopecic patches occurs spontaneously without treatment, it is important to recognize this disorder to establish a correct diagnosis and inform patients about this transient side effect. We report a 44-year-old woman presenting with temporary alopecia after embolization of an arteriovenous malformation.

[Postoperative course after acute traumatic subdural hematoma in the elderly. Does the extent of craniotomy influence outcome?]. / Postoperativer Verlauf nach akutem Subduralhämatom im höheren Lebensalter. Hat das Ausmaß der Kraniotomie einen Einfluss auf das Ergebnis?

AIM: The goal of the study was to analyze the short-term outcome after surgical treatment of acute subdural hematomas in two treatment groups in a patient population >65 years. Whether there are disadvantages from invasive treatment or whether advantages can be achieved with the less invasive treatment has not been previously examined in a prospective study. METHODS: A prospective, nonrandomized study of 50 patients >65 years with acute traumatic subdural hematoma was performed, comparing the short-term outcome after two different primary surgical procedures: limited craniotomy (group A, n=25) and large decompressive craniectomy (group B, n=25). RESULTS: There were no differences of hematoma volume, degree of midline structure shift, and time from trauma to operation between the two groups. Initial Glasgow coma scale and short-term outcome after 4 weeks measured by the Glasgow outcome score in both groups showed no significant differences. CONCLUSION: No significant differences between short-term outcome after limited craniotomy versus large decompressive craniectomy were found for patients >65 years, and the results indicate that decompressive craniectomy can be accepted as a surgical treatment option for acute traumatic subdural hematoma even in elderly patients.

Intracerebral haematoma following spinal anaesthesia for caesarean section: case report.

Several complications are known to occur with spinal anaesthesia and all of them are easily recognizable. We report the case of a 25 year old woman presenting with intracerebral hemorrhage secondary to spinal anaesthesia for caesarean section. She underwent surgical evacuation of the haematoma with complete recovery. The relevant literature is also reviewed.

Concomitant Intracranial Chronic Subdural Hematoma and Spinal Subdural Hematoma: A Case Report and Literature Review.

BACKGROUND: Concomitant intracranial chronic subdural hematoma (CSDH) and spinal subdural hematoma (SDH) are rare, and the etiology has yet to be elucidated. However, migration of the hematoma intracranially to a spinal site or coincidence of both intracranial and spinal CSDHs have been proposed as etiologies. We report a case of concomitant intracranial CSDH and spinal SDH in which spinal hematoma might have migrated from the cranial lesion. CASE DESCRIPTION: A previously healthy 58-year-old man with previous trauma to the occiput and lumbar spine suffered from headache, lumbago, and left hemiparesis. Head computed tomography revealed right-sided intracranial CSDH, and he underwent single burr-hole craniotomy. Although clinical symptoms tended to improve, left lower-limb weakness and lumbago remained. Spinal magnetic resonance imaging (MRI) 3 days after craniotomy revealed SDH extending from T1-S1. Because conservative therapy had not improved clinical symptoms, hematoma evacuation was performed via a left L5 hemilaminectomy 1 week after craniotomy. The patient showed complete recovery immediately postoperatively. CONCLUSIONS: We reviewed the cases of 22 patients with concomitant intracranial CSDH and spinal SDH to discuss the features, etiology, and treatment strategy. Although surgical intervention was mainly selected for intracranial CSDH, conservative observation was mainly selected for spinal SDH. Outcomes were good in all patients. We created a new classification of spinal SDH shape using sagittal MRI. This classification indicates that cases with both ventral and dorsal SDH tend to require surgical intervention. This classification may help in deciding treatment strategies.

Decompressive hemicraniectomy with or without clot evacuation for large spontaneous supratentorial intracerebral hemorrhages.

OBJECTIVE: The management of patients with supra-tentorial intracerebral hemorrhage (ICH) remains controversial. Here we critically evaluate the safety, feasibility, and outcomes following decompressive hemicraniectomy (HC) with or without clot evacuation in the management of patients with large ICHs. METHODS: We analyzed data from 73 consecutive patients managed with a HC for a spontaneous ICH. All relevant patient variables at initial presentation and management were compiled. Variables were modeled as independent regressors against the three-month Glasgow Outcome Score using a multivariate logistic regression model. RESULTS: Over 7 years, HC was performed in 73 patients with clot evacuation in 86% and HC alone in 14%. The average ICH volume was 81 cc and the median HC surface area was 105 cm(2). 26 patients were comatose at initial presentation. Three-month functional outcomes were favorable in 29%, unfavorable in 44% and 27% of patients expired. Admission Glasgow Coma Scale (p = 0.003), dominant hemisphere ICH location (p = 0.01) and hematoma volume (p = 0.002) contributed significantly to the outcome, as estimated by a multivariate analysis. Eight surgical complications occurred. CONCLUSIONS: Early HC with or without clot evacuation is feasible and safe for managing spontaneous ICH. Our experience in this uncontrolled retrospective series, the largest such series in the modern era, suggests that it may be of particular benefit in patients with large non-dominant hemisphere ICH who are not moribund at presentation. Our findings suggest that a prospective randomized trial of HC vs. craniotomy for ICH be conducted.

Organized hematoma developed after suboccipital craniectomy.

An organized hematoma shows a heterogeneous signal intensity on T1-and T2-weighted images on MR imaging, reflecting variable stages of hemorrhage. Although rather nonspecific, precontrast CT images of an organized hematoma demonstrate inhomogeneous hyperdense mass with or without calcification. We report a case of an organized hematoma in a 44-year-old man, which developed 5 years after decompressive suboccipital craniectomy following acute cerebellar infarction. To our best knowledge, there has been no report describing organized hematoma in the suboccipital craniectomy site. Computed tomography and magnetic resonance imaging findings of the organized hematoma are shown and discussed. We believe that recognition of the characteristic imaging findings of the organized hematoma as well as consideration of the history of surgery or anticoagulation treatment assists in its correct diagnosis enabling an inappropriate surgery to be avoided.

Intracranial subdural hematoma and pneumocephalus after spinal instrumentation of myelodysplastic scoliosis.

To report a case of acute intracranial subdural hematoma, pneumocephalus, and pneumorachis, which occurred because of cerebrospinal fluid (CSF) leak caused by a malpositioned transpedicular screw during spinal surgery for severe myelodysplastic scoliosis accompanied with hydrocephalus. Intracranial hemorrhage may occur as a consequence of dural sac penetration and CSF leakage after various medical procedures at the spinal level. The awareness of this severe complication is especially important during spinal instrumentation procedures in which inadvertent dural sac violation and CSF loss may be overlooked. A case report and literature review are presented here. A 12-year-old girl with a history of myelomeningocele and hydrocephalus underwent instrumentation for severe myelodysplastic scoliosis. Postoperatively, she became aphasic and increasingly somnolent. An urgent computed tomographic scan of the head and spine showed massive intracranial hematoma, pneumocephalus, pneumorachis, and a malpositioned pedicular screw that caused CSF leakage, intracranial hypotension, and bleeding remote from the surgical site. The patient needed neurosurgical cranial decompression and subsequent spinal reoperation with dural tear repair. The final outcome was an uneventful complete recovery. The increasing use of pedicular screws in spinal surgery carries a potential risk of occult dural sac violation with subsequent CSF leakage, intracranial hypotension, and the possibility of intracranial bleeding and pneumocephalus remote from the surgical site. This potentially fatal complication should always be considered after spinal surgery in the presence of early signs of neurological deterioration and necessitates an urgent cranial and spinal imaging to confirm the diagnosis and to make adequate treatment decisions.

Hematoma in the splenium of the corpus callosum in the subacute stage of subarachnoid hemorrhage--three case reports.

Three patients developed hemorrhage in the splenium of the corpus callosum 2 weeks after the onset of subarachnoid hemorrhage (SAH) associated with acute hydrocephalus. Computed tomography performed a few days after the onset showed a low density area in the splenium of corpus callosum in all three patients, and preventive measures against symptomatic vasospasm were begun, including vasodilator administration. Computed tomography showed hemorrhage in the splenium of the corpus callosum 17 to 22 days after onset of SAH, manifesting as mental deterioration or headache. Antivasospasm agents were immediately discontinued, and strict blood control measures were instituted. Splenial hematoma is another potential cause of neurological deterioration after surgery for SAH, in addition to vasospasm, hydrocephalus, and rebleeding.

[Epidural haematoma after operative evacuation of an acute subdural haematoma. Discussion of primary treatment illustrated by an unusual case]. / Epiduralhämatom nach Entlastung eines akuten Subduralhämatoms. Diskussion der Primärversorgung anhand eines ungewöhnlichen Falles.

Subdural haematomas as a consequence of severe head injury often constitute the indication for operative evacuation. Despite intensive care management postoperative computed tomography scans are essential. This is illustrated by an unusual case report of a patient suffering from an epidural haematoma after operation of an subdural haematoma. In addition, the importance of the skull X-ray in the emergency setting and intracranial pressure monitoring are discussed.
