1/191. Intraspinal epidermoid cyst occurring 15 years after lipomyelomeningocele repair. Case report.The authors report the case of a spinal epidermoid cyst that developed in a patient who had undergone surgery for lipomyelomeningocele repair 15 years earlier. The patient presented with symptoms of retethering. magnetic resonance imaging revealed a cystic intraspinal mass that extended from L-2 to L-5. The mass proved to be an epidermoid cyst. Spinal epidermoid cysts can cause retethering after a repair of lipomyelomeningocele, and the risk of this development can be present for decades.- - - - - - - - - - ranking = 1keywords = meningocele (Clic here for more details about this article) |
2/191. Migration of the abdominal catheter of a ventriculoperitoneal shunt into the scrotum--case report.A 3-day-old male neonate presented with migration of the ventriculoperitoneal (VP) shunt tip through the patent processus vaginalis resulting in scrotal hydrocele. The association of myelomeningocele with hydrocephalus may have been a predisposing factor in this rare complication. Development of scrotal swelling or hydrocele in a child with VP shunt should be recognized as a possible shunt complication.- - - - - - - - - - ranking = 0.16666666666667keywords = meningocele (Clic here for more details about this article) |
3/191. Once a shunt, always a shunt?Over a period of 15 years, during which some 1000 operations were performed, CSF-drainage systems were able to be removed in 40 of a total of 444 children with communicating hydrocephalus or hydrocephalus associated with myelomeningocele. Shunts were removed from 26 children in the former group, of whom 17 continued to be compensated; in the latter group there were 14 removals, all of whom remained compensated. It is stressed that true compensation can be proven only by continuous measurement of ventricular fluid pressure over periods of several hours or at intervals of days or weeks, and four cases are discussed in which decompensation occurred, in two cases with fatal results.- - - - - - - - - - ranking = 0.16666666666667keywords = meningocele (Clic here for more details about this article) |
4/191. Combined anomaly of intramedullary arteriovenous malformation and lipomyelomeningocele.We report a rare situation in which a lipomyelomeningocele and an intramedullary arteriovenous malformation (AVM) occurred together at the T11-L1 level in a 44-year-old man. MR images showed a hypervascular lesion intradurally and a fatty component extradurally. Spinal angiography revealed this lesion to be an intramedullary AVM with multiple feeding arteries from the right T12 and left T10 intercostal artery and the left L1 lumbar artery, drained by tortuous, dilated, perimedullary veins.- - - - - - - - - - ranking = 0.83333333333333keywords = meningocele (Clic here for more details about this article) |
5/191. neural tube defects and the 13q deletion syndrome: evidence for a critical region in 13q33-34.neural tube defects (NTD) are common findings in the 13q deletion syndrome, but the relationship between the 13q- syndrome and NTDs is poorly understood. We present a child with a 13q deletion and lumbosacral myelomeningocele. This was a boy with microcephaly, telecanthus, minor facial anomalies, and ambiguous genitalia. Cytogenetic and fluorescence in situ hybridization analysis showed a de novo 46,XY,del(13)(q33.2-->qter) with no visible translocation. By using microsatellite markers, the deletion breakpoint was mapped to a 350-kb region between D13S274 and D13S1311 and was paternal in origin. An analysis of 13q deletions with NTDs, including the present case, suggests that a deletion in 13q33-34 is sufficient to cause an NTD. The deletions associated with NTDs are distal to and nonoverlapping with the previously defined critical region in 13q32 for the major malformation syndrome [Brown et al., 1999: Am J Hum Genet 57: 859-866]. Our analysis also suggests that one or more genes in 13q33-34 produces NTDs by haploinsufficiency.- - - - - - - - - - ranking = 0.16666666666667keywords = meningocele (Clic here for more details about this article) |
6/191. Detection of skin over cysts with Spina bifida may be useful not only for preventing neurological damage during labor but also for predicting fetal prognosis.Spina bifida is one of the most common open neural tube defects. There are two common types of spina bifida cystica, myelomeningocele and meningocele. Special attention to the thickness of the cystic sac (presence of intact skin and subcutaneous tissue) on magnetic resonance imaging is advantageous for determination of whether the child will profit from cesarean section in order to prevent neurological change (infection and drying of nerve tissue) and for management of spina bifida (most meningocele) during the perinatal period. Furthermore, skin detection may help to predict the prognosis of spina bifida after birth. meningocele, with intact skin over the cyst, has a better clinical course than myelomeningocele. Some myelomeningoceles with neural tube defects in a lower position, also frequently having an intact skin over the cyst, have almost the same clinical course as a meningocele. From this, we hypothesize that a baby with spina bifida who has intact skin over the cyst might have a good prognosis neurologically. In this report, we concentrate attention on the skin over cysts in 3 cases (1 meningocele and 2 myelomeningoceles).- - - - - - - - - - ranking = 1.3333333333333keywords = meningocele (Clic here for more details about this article) |
7/191. Terminal Myelocystocele:an unusual presentation.Terminal myelocystocele is an unusual form of occult spinal dysraphism. It consists of a cystic dilatation of a low-lying terminal cord herniated posteriorly through a skin-covered lumbosacral spina bifida. An arachnoid-lined meningocele, continuous with the spinal subarachnoid space, is traversed by the hydromyelic cord. Clinically, this presents with a skin-covered lumbosacral mass, but often no neurological deficit is present. We present a case of terminal myelocystocele in a child born without deficit and without an obvious back mass. diagnosis was delayed until sphincter disturbance and lower limb inequalities developed. We discuss the presentation, imaging and operative findings in this case.- - - - - - - - - - ranking = 0.16666666666667keywords = meningocele (Clic here for more details about this article) |
8/191. gait analysis in myelomeningocele: possibilities and applications.gait analysis with a fully integrated laboratory is a relatively new instrument in the armamentarium of the pediatric orthopedic surgeon. The introduction of it has been especially successful in neuromuscular pathology and, particularly, in cerebral palsy. In spina bifida, however, it also enhances substantially the possibilities of detailed analysis of the locomotion problem. It is, furthermore, a very useful instrument in evaluating treatment and in follow-up. With a few examples, this paper tries to show the possibilities and advantages of a gait laboratory in the evaluation of patients with ambulatory spina bifida.- - - - - - - - - - ranking = 0.66666666666667keywords = meningocele (Clic here for more details about this article) |
9/191. Prenatal sonographic diagnosis of uterine rupture following open fetal surgery.BACKGROUND: Reported cases of uterine rupture diagnosed by ultrasound have shown fetal membranes ballooning through uterine rupture sites, or adjacent areas of hemorrhage. CASE: A 27-year-old gravida 3, para 2 had open fetal surgery to repair a fetal myelomeningocele at 28 weeks' gestation. Her postoperative course was complicated by threatened preterm labor and anhydramnios. At 33 weeks' gestation, with maternal symptoms of bowel obstruction, ultrasound showed a fetal leg and section of umbilical cord protruding through the uterine wall. CONCLUSION: Even in the presence of anhydramnios, uterine wall rupture was identified, because ultrasound evaluation of the uterine wall showed prolapsed fetal parts and umbilical cord. Persistent anhydramnios after open fetal surgery should prompt a search for uterine rupture.- - - - - - - - - - ranking = 0.16666666666667keywords = meningocele (Clic here for more details about this article) |
10/191. Deep wound infections after neuromuscular scoliosis surgery: a multicenter study of risk factors and treatment outcomes.STUDY DESIGN: A retrospective case-control study evaluating risk factors for infection, causative organisms, and results of treatment in patients with cerebral palsy or myelomeningocele who underwent fusion for scoliosis was performed. OBJECTIVES: To identify risk factors for infection, and to characterize the infections in terms of infecting organisms and response to treatment. SUMMARY OF BACKGROUND DATA: No previous studies have analyzed risk factors or causative organisms, nor have they indicated results of treatment for infections in this group of patients. methods: After a 10-year retrospective review of 210 surgically treated patients, deep wound infections developed in 16 patients with myelomeningocele and 9 patients with cerebral palsy. These patients were studied extensively for possible risk factors, along with 50 uninfected patients matched for age, diagnosis, and year of surgery. Statistical testing was performed to identify risk factors. The courses of the infections were characterized in terms of organisms isolated and response to treatment. Treatment was performed in a stepwise fashion and classified in terms of the most successful step: debridement and closure, granulation over rods, or instrumentation removal. RESULTS: Of the 10 risk factors tested, 2 were found to be significant: degree of cognitive impairment and use of allograft. Findings showed that 52% of the infections were polymicrobial. Gram-negative organisms were isolated as commonly as gram-positive organisms. The most common organisms were coagulase-negative staphylococcus, enterobacter, enterococcus, and escherichia coli.- debridement and closure were successful in 11 of 25 patients with deep wound infection. Of the 14 patients with infection not resolved by serial debridements and closure, 2 were managed successfully by allowing the wound to granulate over rods, and 7 required rod removal for persistent wound drainage. There were three symptomatic pseudarthroses. Infections resulting from gram-positive organisms were most often managed successfully with debridement and closure (P = 0.012). CONCLUSIONS: patients with cerebral palsy or myelomeningocele who have severe cognitive impairment, and those who received allograft may be at increased risk for infection. Infections are more often polymicrobial and caused by gram-negative organisms than is typical for elective orthopedic procedures. This suggests an enteric source. Treatment with debridement and closure was not always successful. patients in whom infection develops are then at increased risk for pseudarthrosis.- - - - - - - - - - ranking = 0.5keywords = meningocele (Clic here for more details about this article) |
