1/8. Severe progressive late onset myelopathy and arachnoiditis following neonatal meningitis.This case series describes four children who had meningitis in the neonatal period. After a stable period of years, they developed a myelopathy caused by chronic arachnoiditis. The myelopathy was precipitated by a fall in two cases, and in two cases there was an acute deterioration after surgery. A history of neonatal meningitis should be taken into consideration before planning surgery or anaesthesia. Careful intra-operative positioning, immobilisation of the neck, and maintenance of blood pressure is important but may not prevent this complication.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/8. Anaesthetic management of a child with fibrodysplasia ossificans progressiva.Fibrodysplasia Ossificans Progressiva (FOP) is a rare inherited disease in which progressive ossification of striated muscles leads to severe disability and respiratory impairment early in life and there are associated characteristic congenital skeletal malformations. Although this condition may prove demanding for the anaesthetist, few reports are available regarding anaesthesia in paediatric patients. We review the clinical features of the disease relevant to anaesthesia and describe the perioperative care of an 18-month-old boy with FOP who underwent endoscopic third-ventriculostomy for hydrocephalus associated with a brainstem mass. We emphasize the importance of an appropriate anaesthetic management of these patients, as inadequate care may lead to exacerbation of the disease with permanent sequelae.- - - - - - - - - - ranking = 2keywords = anaesthesia (Clic here for more details about this article) |
3/8. Rhombencephalosynapsis presenting antenatally with ventriculomegaly/hydrocephalus in a likely case of Gomez-Lopez-Hernandez syndrome.Rhombencephalosynapsis is a rare cerebellar malformation that can be associated with anomalies of the cerebral hemispheres and variable degrees of neurodevelopmental delay. A syndromic association, comprising rhombencephalosynapsis, developmental delay, scalp alopecia and trigeminal anaesthesia (Gomez-Lopez-Hernandez syndrome) has been described in seven individuals. We report the case of a 2-year-old boy with rhombencephalosynapsis, and review the evidence for a possible diagnosis of Gomez-Lopez-Hernandez syndrome. We also discuss other malformations reported in combination with rhombencephalosynapsis, and consider the possibility that a genetic aetiology for syndromic and nonsyndromic forms of rhombencephalosynapsis may be established with more detailed clinical and genetic studies.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
4/8. Neurogenic pulmonary oedema precipitated by induction of anaesthesia.Neurogenic pulmonary oedema is a recognized complication of central nervous system injury. A case is presented where this condition was precipitated by induction of anaesthesia in a child with spina bifida, hydrocephalus and a malfunctioning ventriculo-peritoneal shunt.- - - - - - - - - - ranking = 5keywords = anaesthesia (Clic here for more details about this article) |
5/8. Anaesthetic management of caesarean section for a mother with pre-eclampsia, the klippel-feil syndrome and congenital hydrocephalus.A mother with the klippel-feil syndrome, congenital hydrocephalus and increased intracranial pressure presented for delivery by Caesarean section at 33 weeks because of pre-eclampsia. Anaesthetic management comprised awake intubation using the fibreoptic bronchoscope, followed by induction and maintenance of general anaesthesia for the delivery of a live male infant. This case report describes the problems arising under these circumstances and the relative merits of different anaesthetic techniques.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
6/8. Cardiac arrhythmia induced by pneumoencephalography.Cardiovascular collapse associated with pneumoencephalography (PNE) has been reported but there has been no prospective study of its nature and cause. We have recorded prospectively the e.c.g. of 82 unselected patients, with no cardiovascular or metabolic disease, undergoing PNE under general anaesthesia. The frequency of arrhythmia following air injection was 60%; bradycardia 22%; ventricular ectopic beats 26%; nodal rhythm or sinus tachycardia 11%. Cardiovascular collapse occurred in three patients; two with "torsades de pointes" and one with bigeminy and q.r.s. block. Arrhythmia was more frequent in patients with a pituitary tumour and intracranial hypertension (91%). Eight postoperative control PNE examinations were uneventful. Three of four patients with frontal lobe tumours and four of seven with posterior fossa tumours exhibited arrhythmia.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
7/8. Endoscopic management of craniopharyngiomas: a review of 3 cases.The authors describe the endoscopic management of cystic craniopharyngiomas in 3 cases. This method has been attempted in cystic craniopharyngiomas using a rigid endoscope. The instrument has been described earlier (7-9). All these operations were done under general anaesthesia. Criteria for endoscopic extirpation and removal included type D, E, F classification according to Yasargil (17). All 3 cases fitted in the F category. There were one female and two male patients. In the female patient an aspiration of cyst contents was performed as a first attempt to relieve her hydrocephalus. Two months later recurrent symptomology necessitated a larger intervention. All cysts were opened using the laser, drained by a Fogarthy balloon-catheter, and the capsule removed by forceps. This technique is safe and provides a reasonable alternative to open microsurgery, radioactive isotope instillation, or radiotherapy. In our series we achieved total removal in one case after the second intervention and partial removal in two cases. There was no mortality directly associated with this procedure and the female patient developed severe electrolyte disturbances after macroscopic total removal. Our results suggest that endoscopic of management of cystic craniopharyngiomas is a safe and effective procedure which could be considered as the initial management for cystic craniopharyngiomas of the intraventricular type.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
8/8. The acquired Chiari malformation and syringomyelia following spinal CSF drainage: a study of incidence and management.Firstly, 14 patients are described who developed either an acquired Chiari malformation (ACM) alone (7 cases) or ACM and syringomyelia (7 cases) after lumbar subarachnoid space (SAS) shunting or in one case, epidural anaesthesia with SAS penetration. Four groups are considered: 3 cases with craniofacial dysostosis and communicating hydrocephalus (CH), 4 cases with CH alone, 3 cases with pseudotumour cerebri (PTC) and a miscellaneous group (4 cases). Initial treatment was varied: resiting the shunt to ventricle or cisterna magna [6], adding an H-V valve [1], syrinx shunting [4] and posterior fossa decompression [3]. Further treatment was required in 6 cases. Secondly, incidence was examined in 87 patients with PTC initially treated either by lumbar SAS shunting [70] or cisterna magna shunting [17]. In the first sub-group, 11 cases (15.7 per cent) developed an ACM, 3 symptomatic (as above) and eight asymptomatic with 1 case also having syringomyelia whereas 1 case occurred in the second group with a questionanably symptomatic ACM. While accurate for symptomatic lesions, these figures are tentative with respect to asymptomatic lesions due to inadequate pre-treatment radiology and detailed MR follow-up. The main conclusions are, first, that the incidence of symptomatic ACM and/or syringomyelia is not high enough to warrant abandoning SAS shunting; second that asymptomatic lesions need not necessarily be treated and third, that when treatment is required, shunt resiting is the first choice.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
