Subdural effusion: results after treatment with subdural-pleural shunts.

In an unselected material of 22 consecutive patients subdural effusion, which did not respond to repeated taps, was treated with subdural-pleural shunt operation using nonvalve silicone catheters. After a mean follow-up time of 3 years 4 months, 17 patients (77%) were mentally and 15 patients (69%) neurologically normal. The results are certainly not worse than results achieved with craniotomies and membranectomies. A shunt operation is more simple and less hazardous than membranectomy and we agree with the opinion that the latter is an obsolete procedure in the treatment of persistent subdural effusions.

Subdural effusions: determination of contrast medium influx from CSF to the fluid accumulation by computed tomography as an aid to the indications for management.

In 46 patients with subdural effusions CSF dynamics and especially the influx of contrast medium from CSF to the subdural fluid accumulation was investigated by serial computed tomography (CT). In 16 cases the subdural effusion was of traumatic and in 30 cases of non-traumatic origin. The results allowed a subdivision of the patients into three groups. Group 1: patients without contrast medium influx into the subdural fluid accumulation; group 2: patients with delayed influx; group 3: patients with immediate influx. In group 1 patients the subdural effusion acted as a space-occupying process with absolute indication for surgical treatment. Also in group 2 patients the further course showed that a surgical indication was given, because the fluid accumulation did not resolve under conservative management but increased in size, and/or the neurological deficit worsened. In all group 3 patients the subdural effusions decreased and finally disappeared conservatively. Group 1 patients with effusions on traumatic origin generally had more severe injuries than the patients of the other groups. The investigations caused no serious complications. This diagnostic method proved to be a reliable means for early differentiation between the possibility of conservative management or the indication for operative treatment in cases with subdural effusions of different origin.

Subdural effusion and brain tumor: case report and survey of the literature.

Optic glioma associated with bilateral subdural effusion in a four-month-old male infant is reported. Review of the cases with subdural effusion or hematoma and brain tumor in the world literature was made. When subdural effusion is found in a newborn or an older infant, the possibility of an associated brain tumor must be considered. Care also should be taken to search for an underlying brain tumor and to exclude dural metastasis when we deal with chronic subdural hematoma in an adult.

Surgical indications for infantile subdural effusion.

Thirty-four cases of infantile subdural effusion (ISE) were reviewed in relation to surgical treatment and its prognosis during an average of 4 years of extended follow-up. The surgical indications were determined mainly by the size of the ISE on computed tomography (CT) scan and by metrizamide CT cisternography (MCTC). Consequently, 18 cases were categorized as type A according to MCTC, including 11 cases (61.1%) of ISE CT grade 1. All type A cases were closely observed. This nontreatment regimen yielded excellent results in 15 cases (83.3%). For 10 cases categorized as type B according to MCTC, including 5 cases (50%) of ISE CT grade 3, surgical treatment was indicated and excellent results were obtained in 8 cases (80%). For 6 cases categorized as type C according to MCTC and as ISE CT grade 3, surgery yielded excellent results in 4 cases (66.7%). Antiepileptic drugs have been given to three (27.3%) of the 11 patients who had convulsive attacks. In conclusion, the surgical indications for ISE were based mainly on MCTC in addition to the clinical course, and it is emphasized that, in the early stages, surgery on ISE cases categorized as MCTC types B and C is necessary.

Simultaneous subdural effusion and hydrocephalus in infancy.

Hydrocephalus and subdural hematoma or effusion of infancy rarely present simultaneously, where both are active contributors to acutely increased intracranial pressure. In three cases, clinical findings characteristic of both were present. Decompression of one can facilitate expansion of the other. Rapid progression of unsuspected hydrocephalus could be responsible for some of the poor results reported after treatment of subdural effusion alone. This possibility should be considered whenever progress is unsatisfactory during treatment of subdural effusion.

[Traumatic aneurysm of the frontopolar artery developing after evacuation of the subdural effusion in a 6-month-old girl (author's transl)].

A 6-month-old girl developed bilateal subdural effusion after head injury. She gradually improved after the partial stripping of the membrane of the subdural effusion although postoperative tappings of the subdural fluid were necessary. Thirty nine days after the injury, she suddenly suffered from a massive intraventricular hemorrhage. A cerebral angiography showed an aneurysm arising from the proximal part of the right frontopolar artery, which had not been revealed in the previous angiograms. It was obscure whether the congenital anomaly of the arterial wall had been existed or not, but this aneurysm might be mentioned as a traumatic aneurysm and definitely developed after the treatment for the traumatic sequence. The mechanism of this aneurysmal formation was supposed that the arterial wall was initially injured by the abnormal traumatic movement of the brain underneath the falx cerebri, and teared arterial wall was further injured by the fluctuating movements of the brain caused by repeated tappings of the effused fluid. Relation of delayed posttraumatic apoplexy and ruptured posttraumatic aneurysms was also discussed, and analysis of the reported cases of the traumatic aneurysm, as well as aneurysm in the infant, was made.

Acute aggravation of subdural effusion associated with pachymeningitis carcinomatosa: case report.

The authors present a case of acute aggravation of subdural effusion associated with pachymeningitis carcinomatosa. Microscopic examination of a surgical specimen revealed diffuse involvement of the dura mater by a metastatic adenocarcinoma in which the tumor cells invaded venules located in the areolar layer in particular. The rapid increase in capillary transmural pressure resulted in extravasation of plasma components, causing an increase in subdural effusion.

[Empyema and subdural effusion after meningitis. 2 cases of unusual location].

A 12-year old child and a 2-month old infant developed, in the wane of a purulent meningitis, the former, an infratentorial subdural empyema, the latter, a large, encapsulated, haemoorhagic, aseptic subdural effusion, in the right parieto-temporo-occipital region. In both cases, signs of intracranial hypertension dominated the clinical picture. Neuroradiological investigations permitted diagnosis and localisation of the expansive processes, whose subdural position was recognized at operation and confirmed by histopathological examination. According to the literature, purulent meningitis is a rare cause of subdural empyema, except in infants; the solely infratentorial location is also unusual. Sterile subdural effusion is a more common complication of purulent meningitis in infancy, but the unilateral posterior supratentorial location is also a peculiar feature. Subdural collections after memingitis may be aseptic and possibly haemorrhagic, or septic and purulent; these different modes of presentation correspond perhaps to different degrees or stages of subdural pathological changes in the neighbourhood of leptomeningeal infection.

Surgical treatment of subdural effusions in infants.

We puropose a simplified method for external drainage of subdural effusions in infants, not calling for a second operation to remove the catheters. This method allows the daily control of evacuated fluid, guarantees smooth and uninterrupted drainage, and permits analysis of the subdural collection. This operation which we would like to call external controlled drainage, does not call for parenteral feeding, but demands paediatric and neurosurgical collaboration. The method has no pretensions other than being simple, easy, and safe.

[Pathogenesis of persistent subdural effusions in infants (author's transl)].

Current theories on the pathogenesis of persistent subdural effusions in infants are not supported by our clinical and operative data. In our more recent cases, a daily electrophoretic analysis of the fluid obtained by external subdural drainage has been performed and allowed to disclose the presence or progressive appearance of cerebro-spinal fluid. The relative concentrations, observed for some proteins present in the fluid collected in this way, cannot be explained by simple filtration, but enforces us to postulate the existence of a free communication between the subarachnoid and the subdural spaces. These first results support our initial hypothesis assuming that persistent effusions are supplied and even replaced by cerebro-spinal fluid, due to the occurrence of a communicating hydrocephalus ruptured in the subdural space. There is thus no sound physiopathological basis for treating these cases with membranectomy and we suggest instead that the treatment of choice should be a fluid derivation.

Gamma-encephalography in the diagnosis of subdural effusions in infancy and childhood.

The results of the use of gamma-encephalography (GEG) as a diagnostic tool in a group of 28 patients with subdural effusions and 46 membranes confirmed at surgery are presented. 27 patients were submitted to bilateral surgical expolorations and 1 was unilaterally explored. Positive GEG: membranes were present in 34, in 8 the test was nonconclusive and there were 4 false-negatives. Negative GEG: membranes were absent in 6, 1 case was nonconclusive and 2 were false-positive tests. Therefore, from 28 patients with 46 membranes the GEG was correct in two thirds of the cases, it was nonconclusive in 9 cases and the image did not confirm the surgical findings in 6 cases (false-positive or false-negative). The results suggest that the presence of a medium or thick membrane almost always results in a positive image, whereas the presence of a thin membrane leads to a nonconclusive result or in some cases a false-negative one. The general data from the literature correlates well with the present series.

Aspirating subdural effusions, so called brain stem shock.

A shift of blood into the head during negative pressure aspiration of subdural haematomas in an infant has been demonstrated, and also that aspiration may restart bleeding. An estimate of the elasticity of a 47 cm circumference skull has been obtained. It is suggested that the observed changes in distribution of blood are sufficient to explain the occasional deaths of infants after aspiration of subdural haematomas and that so-called "brain stem shock" need not be invoked.
