The incidence of postoperative hydrocephalus and factors relating to it were analyzed in 257 patients undergoing cranial base surgery for tumor resection. A total of 21 (8%) patients developed postoperative hydrocephalus, and all required shunting, Forty-two (17%) patients developed cerebrospinal fluid (CSF) leak that required placement of external drainage systems (ventriculostomy or lumbar drain, or both); 10 (23%) of these 42 patients eventually needed shunt placement to stop the leak because of hydrocephalus. Prior craniotomy, prior radiation therapy, and postoperative CSF infection were also associated with an increased risk of developing hydrocephalus (48% versus 6%, 19% versus 8%, and 14% versus 7%, respectively). Prior radiation and postoperative CSF infection increased the risk of CSF leak in patients with hydrocephalus (30% versus 18% and 30% versus 9%, respectively). CSF leak and hydrocephalus commonly occurred in patients who underwent resection of a glomus tumor. In conclusion, 8% of patients who underwent cranial base surgery for tumors developed de novo hydrocephalus; half of them also had CSF leak in addition to hydrocephalus; and all required shunt placement for CSF diversion. 相似文献

OBJECT: The authors undertook a study to evaluate the effectiveness of endoscopic third ventriculostomy in the management of hydrocephalus before and after surgical intervention for posterior fossa tumors in children. METHODS: Between October 1, 1993, and December 31, 1997, a total of 206 consecutive children with posterior fossa tumors underwent surgery at H?pital Necker-Enfants Malades in Paris. Excluded were 10 patients in whom shunts had been placed at the referring hospital. The medical records and neuroimaging studies of the remaining 196 patients were reviewed and categorized into three groups: Group A, 67 patients with hydrocephalus present on admission in whom endoscopic third ventriculostomy was performed prior to tumor removal; Group B, 82 patients with hydrocephalus who did not undergo preliminary third ventriculostomy but instead received conventional treatment; and Group C, 47 patients in whom no ventricular dilation was present on admission. There were no significant differences between patients in Group A or B with respect to the following variables: age at presentation, evidence of metastatic disease, extent of tumor resection, or follow-up duration. In patients in Group A, however, more severe hydrocephalus was demonstrated (p < 0.01): the patients in Group C were in this respect different from those in the other two groups. Ultimately, there were only four patients (6%) in Group A compared with 22 patients (26.8%) in Group B (p = 0.001) in whom progressive hydrocephalus required treatment following removal of the posterior fossa tumor. Sixteen patients (20%) in Group B underwent insertion of a ventriculoperitoneal shunt, which is similar to the incidence reported in the literature and significantly different from that demonstrated in Group A (p < 0.016). The other six patients (7.3%) were treated by endoscopic third ventriculostomy after tumor resection. In Group C, two patients (4.3%) with postoperative hydrocephalus underwent endoscopic third ventriculostomy. In three patients who required placement of CSF shunts several episodes of shunt malfunction occurred that were ultimately managed by endoscopic third ventriculostomy and definitive removal of the shunt. There were no deaths; however, there were four cases of transient morbidity associated with third ventriculostomy. CONCLUSIONS: Third ventriculostomy is feasible even in the presence of posterior fossa tumors (including brainstem tumors). When performed prior to posterior fossa surgery, it significantly reduces the incidence of postoperative hydrocephalus. The procedure provides a valid alternative to placement of a permanent shunt in cases in which hydrocephalus develops following posterior fossa surgery, and it may negate the need for the shunt in cases in which the shunt malfunctions. Furthermore, in patients in whom CSF has caused spread of the tumor at presentation, third ventriculostomy allows chemotherapy to be undertaken prior to tumor excision by controlling hydrocephalus. Although the authors acknowledge that the routine application of third ventriculostomy in selected patients results in a proportion of patients undergoing an "unnecessary" procedure, they believe that because patients' postoperative courses are less complicated and because the incidence of morbidity is low and the success rate is high in those patients with severe hydrocephalus that further investigation of this protocol is warranted. 相似文献

Summary Of 148 patients with infratentorial brain tumours which were operated upon during a 5 year period, 59 patients had associated obstructive hydrocephalus, as evidenced by preoperative CT scan. External ventricular drainage was performed in these cases at time of surgery. CSF drainage was continued in the postoperative period for a mean of 2.3 (± 1.6) days. Only 6 of these 59 patients (10%) required a subsequent indwelling shunt. The infection rate was 10% and the total mortality was 8%. Perioperative ventricular drainage during and following the removal of posterior fossa tumours causing hydrocephalus provides an effective alternative to the preoperative placement of an indwelling shunt. Problems of shunt dysfunction, tumour seeding and upward herniation are thereby avoided. Post-operative ICP monitoring and drainage of blood and debris laden CSF is performed, increasing the safety of the postoperative period and possibly reducing the incidence of aspetic meningitis and post-operative shunt requirement. 相似文献

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) may be required in neurosurgical patients with a persistently depressed neurological status or severe lower cranial nerve palsies. Such patients may have a coexisting hydrocephalus requiring cerebrospinal fluid (CSF) diversion. Despite the risk of infection resulting from exposure to oropharyngeal flora by the pull-through PEG technique and the secondary pneumoperitoneum seen in one-third of patients, simultaneous peritoneal placement of CSF shunt catheters with PEG is the current practice. The aim of the study was to determine the frequency of CSF diversionary procedures in neurosurgical patients undergoing PEG insertion and the occurrence of infective complications in patients with simultaneous placement of a PEG and a ventriculoperitoneal (VP) shunt. METHODS: This was a retrospective review of all neurosurgical patients undergoing PEG. The presence of hydrocephalus, mode of CSF diversion and the development of subsequent infection in those having coexistent distal peritoneal catheter placement and PEG were determined. RESULTS: PEGs were placed in 42 neurosurgical patients (9.3 per cent of all PEGs inserted), of whom 21 had a coexisting hydrocephalus. Eight of 16 shunts with distal catheter placement in the peritoneal cavity developed infection requiring revision. Infections occurred with greater frequency in patients with a tracheostomy. There were no shunt infections requiring revision in a second group of 21 patients who had a coexisting shunt and tracheostomy without PEG. CONCLUSION: Simultaneous placement of a PEG and a VP shunt should be avoided in the acute phase of a patient's hospital admission. 相似文献

BACKGROUND: The development of various neuroendoscopic surgical instruments has offered more options for endoscopic procedures in the treatment of intraventricular tumors. Not only tumor biopsy or tumor resection but also restoration of an obstructed cerebral spinal fluid (CSF) pathway can be performed using the same approach. METHOD: A 76-year-old woman with a cardiac pacemaker for an underlying heart disease was diagnosed with obstructive hydrocephalus because of a third ventricular tumor 8 years ago. The patient had been treated with ventriculo-peritoneal shunt placement. At admission she presented with a subcutaneous infection of the shunt catheter and an abdominal mass of unknown etiology. Neuroendoscopic stenting between lateral and third ventricle was performed to restore the obstructed CSF pathway, and the infected shunt system was removed in the same setting. RESULT: The postoperative course was uneventful. Contrast ventriculography demonstrated a restored CSF pathway between the lateral and third ventricle. Histologic examination of the intraventricular tumor revealed a craniopharyngioma, and the abdominal mass was diagnosed as a gastrointestinal adenocarcinoma. CONCLUSION: The neuroendoscopic foraminoplasty technique should be considered as an alternative treatment for patients who present with an obstructive hydrocephalus caused by a tumor that occludes both foramina of Monro when shunt placement or endoscopic third ventriculostomy is not feasible. 相似文献

Subdural patch graft technique for watertight closure of large dural defects in extended transsphenoidal surgery 总被引:6,自引:0,他引:6
OBJECTIVE: The most common postoperative complication of the transsphenoidal approach is cerebrospinal fluid (CSF) rhinorrhea. If the dura is widely opened beyond the sellar floor and massive intraoperative CSF leakage is encountered, then the conventional packing method, in which the sella turcica is filled with pieces of fat or muscle, demonstrates a relatively high incidence of CSF rhinorrhea. For more reliable prevention of postoperative CSF leakage, we developed a method for watertight closure of large dural defects. METHODS: For 34 consecutive patients with suprasellar tumors, we performed tumor resection via an extended transsphenoidal approach, in which the surgical window in the sellar floor was extended to the planum sphenoidale to expose the suprasellar cistern. The patients were retrospectively divided into three groups according to the dural defect closure technique used. Group I consisted of the first two patients, whose large dural openings were closed with a conventional fat-packing method. Group II consisted of the next 10 patients, whose large dural defects were patched with fascia and sutured with 5-0 nylon, in a watertight manner. Group III consisted of the last 22 patients, who underwent watertight dural closure with a new knot-tying technique and a double-layer patch graft, which generously covered the dural defect of the cranial base with subdural placement. In Group III, intracranial CSF compressed the patch graft against the cranial base and sealed the gap between the patch graft and the cranial base in a watertight manner. The double-layer patch graft was composed of autologous fascial membrane and a commercially available, expanded polytetrafluoroethylene dural substitute. RESULTS: Postoperative CSF leakage was noted for 50% of the patients in Group I, 30% of the patients in Group II, and 9% of the patients in Group III. The time required for dural closure for Group III was approximately 50% shorter than that required for Group II (45.9 +/- 12.4 min versus 93.5 +/- 19.1 min, P < 0.001). CONCLUSION: The subdural double-layer patch graft technique is simple and reliable for the prevention of CSF rhinorrhea after transsphenoidal surgery associated with a widely opened dura. 相似文献

Cerebrospinal fluid shunt infection: a prospective study of risk factors 总被引:19,自引:0,他引:19
OBJECT: Hydrocephalus is a common condition of childhood that usually requires insertion of a cerebrospinal fluid (CSF) shunt. Infection is one of the most devastating complications that may arise from the presence of CSF shunts. In this study, the authors prospectively analyzed perioperative risk factors for CSF shunt infection in a cohort of children. METHODS: Between 1996 and 1999, 299 eligible patients underwent CSF shunt operations (insertions and revisions) that were observed by a research nurse at a tertiary care pediatric hospital. Several perioperative variables were recorded. All cases were followed postoperatively for 6 months to note any development of CSF shunt infection. A Cox proportional hazards model was used to analyze the relationship between the variables and the development of shunt infection. Thirty-one patients (10.4%) experienced shunt infection. Three perioperative variables were significantly associated with an increased risk of shunt infection: 1) the presence of a postoperative CSF leak (hazard ratio [HR] 19.16, 95% confidence interval [CI] 6.96-52.91); 2) patient prematurity (< 40 weeks' gestation at the time of shunt surgery: HR 4.72, 95% CI 1.71-13.06), and 3) the number of times the shunt system was inadvertently exposed to breached surgical gloves (HR 1.07, 95% CI 1.02-1.12). CONCLUSIONS: Three variables associated with an increased incidence of shunt infection have been identified. Changes in clinical practice should address these variables, as follows. 1) Great care should be taken intraoperatively to avoid a postoperative CSF leak. 2) Alternatives to placement of a CSF shunt in premature infants should be studied. 3) Surgeons should minimize manual contact with the shunt system and consider the use of double gloves. 相似文献

Results of surgical treatment of neurocysticercosis in 69 cases 总被引:5,自引:0,他引:5

The clinical course of 69 patients with neurocysticercosis who underwent surgery to control increased intracranial pressure (ICP) or cyst removal is analyzed. Increased ICP was caused by hydrocephalus in 63 patients, by cerebral edema in four, and by giant cysts in two. Skull x-ray films showed calcifications in 14% and signs of elevated ICP in 46%. Examination of cerebrospinal fluid (CSF) revealed pleocytosis with eosinophils in 52% of cases and a positive complement fixation test for cysticercosis in 66%. Ventriculography allowed localization of the CSF obstruction and ventricular cysts, and generally differentiated between an obstruction due to cysts and an inflammatory process. Computerized tomography showed cysts in the cerebral parenchyma and ventricular dilatation. Ventricular cysts were best seen when intraventricular metrizamide was used. Intracranial shunting and posterior fossa exploration were less effective in the treatment of hydrocephalus than was ventriculoatrial (VA) or ventriculoperitoneal (VP) shunting, although VA or VP shunting was associated with a high percentage of complications. Quality of survival was good in 87% of the cases in the first 3 postoperative months and in 93% of patients who survived 2 years after surgery. Forty-seven patients (68%) were readmitted one or more times for CSF shunt revision; 14 of them for shunt infection (meningitis). The early operative mortality rate was 1.8% for patients with VA or VP shunt placement and 5.3% for those with posterior fossa exploration. The authors conclude that placement of CSF shunts is indicated in the treatment of hydrocephalus, and cyst removal is indicated only when the cyst exhibits tumor-like behavior. Surgical exploration is also indicated when the diagnosis is uncertain. 相似文献

OBJECTIVES: The purpose of this article is to outline our methods for the prevention and management of cerebrospinal fluid (CSF) leak after transtemporal skull base surgery. METHODS: A total of 589 patients underwent a variety of transtemporal surgical approaches for the extirpation of skull base tumors at our institution from July 1988 to October 1999. The medical records were retrospectively reviewed to identify the tumor histology, size, and location as well as the surgical approach, defect reconstruction technique, and the incidence of postoperative CSF leak. RESULTS: The risk of CSF fistulae was greatest in utilizing the restrosigmoid approach (8%) and least in those who underwent a translabyrinthine approach (4%). Tumor size had no bearing on the incidence of the CSF leak and the overall incidence of meningitis was 1.0%. CONCLUSION: The proper surgical technique will minimize the risk of CSF leak after transtemporal skull base surgery. Immediate management of CSF fistulae helped prevent meningitis in the majority of these patients. 相似文献

The incidence of cerebrospinal fluid (CSF) fistula after transtemporal skull base surgery can range from 4% to 19%. The risk of CSF leak may be related to tumor size and location, the extent of the dural defect, and the technical aspects of the wound reconstruction. Prevention of meningitis depends on the early detection and management of CSF leakage. Five hundred eighty-nine patients underwent a variety of transtemporal surgical approaches for the extirpation of skull base tumors at our institution from July 1988 to October 1999. The medical records were reviewed retrospectively to identify the tumor histology, size, and location, as well as the surgical approach, defect reconstruction technique, and the incidence of postoperative CSF leak. The risk of CSF fistulae was greatest in using the retrosigmoid approach (8%) and lowest in those who underwent a translabyrinthine approach (4%). Tumor size had no bearing on the incidence of the CSF leak and the overall incidence of meningitis was 1.0%. This article outlines our institutional objective for the prevention and management of CSF fistula after transtemporal skull base surgery. Illustrative cases will be presented. 相似文献

Background
Cerebrospinal fluid (CSF) protein levels are known to increase in patients with vestibular schwannomas (VS) with concomitant hydrocephalus, however the only information available on perioperative changes in CSF in these patients comes from case reports. Here, we investigated the relation between CSF protein and hydrocephalus in a large series of patients undergoing resection of VS.Method
We classified 376 patients undergoing resection for VS at our institute into two groups, namely VS and no hydrocephalus (control, n?=?319) and VS with concomitant hydrocephalus (n?=?57), and compared clinical parameters. Among the 57 patients diagnosed with hydrocephalus, hydrocephalus status was examined by lumbar puncture in 20 patients with communicative hydrocephalus, and pre- and postoperative scores in CSF properties were compared.Results
Patients in the hydrocephalus group were significantly older than those in the control group (mean, 55.8 vs. 43.8 years), and had a longer disease duration (median, 76 vs. 12 months), larger tumors (median, 15.6 vs. 5.5 ml), and a higher protein concentration in CSF (median, 147.3 vs. 65.1 mg/dl). Perioperative CSF samples of hydrocephalus patients showed a significantly decrease in cerebrospinal pressure after tumor removal (median, -75mmH2O), followed by a decrease in CSF protein (median, -74.5 mg/dl). No patients required the placement of a shunt.Conclusions
Extended disease duration and elevated CSF protein secondary to the presence of a tumor contribute to the occurrence of hydrocephalus. Primary maximal tumor removal for VS with coexisting hydrocephalus avoids an unnecessary shunt. 相似文献12.
Objectives Temporal bone encephaloceles are usually encountered in the setting of a congenital defect of the tegmen or as an acquired defect after mastoid surgery. A variety of methods have been described in the literature for rigid reconstruction of tegmen defects. We introduce a new method of repair using orbital floor titanium mesh reconstruction plates to reconstruct the floor of the middle cranial fossa, and evaluate the outcomes, complications, and recurrence rates of temporal bone encephaloceles with this technique.
Design Retrospective chart review of consecutively treated patients.
Setting Tertiary care academic center.
Participants Eight patients with middle cranial fossa skull base defects from January 2007 to February 2011.
Main Outcome Measures Outcome measures included resolution of cerebrospinal fluid leak (CSF) and development of postoperative infection.
Results One of nine patients had a postoperative CSF (cerebrospinal fluid) leak. There were no long-term complications of CSF leak or infection.
Conclusions Titanium mesh is a safe and effective substitute for bone grafts in reconstruction of the middle cranial fossa skull base when rigid reconstruction is required. 相似文献

OBJECTIVE: We sought to demonstrate the technical aspects of the extended pericranial flap and its versatility in reconstruction of a variety of skull base defects. STUDY DESIGN: We conducted a retrospective chart review of 32 patients who underwent reconstruction of skull-base defects with an extended pericranial flap by the senior author (Y.D.) from September 1997 to July 2003. METHODS: Patients with skull base defects after trauma or extirpative surgery were reconstructed with either a lateral- or an anterior-based vascularized extended pericranial flap. Variables and outcomes measured included: the size and anatomical location of the defect, need for other flaps, preoperative and/or postoperative radiation therapy and/or chemotherapy, bone flap necrosis, hardware exposure, wound dehiscence, postoperative cerebrospinal fluid (CSF) leak, and meningitis. RESULTS: There was no evidence of flap failure, 2 cases of transient (3 to 4 days) CSF leak without resultant meningitis, 3 patients with hardware exposure, and 2 patients with hydroxyapatite infection. The 2 transient cases of CSF leak both resolved without further surgical intervention or the placement of a lumbar drain. CONCLUSION: Both the lateral and anteriorly based extended pericranial flaps are reliable and versatile flaps associated with minimal morbidity and a low rate of complications when used to reconstruct defects of the anterolateral skull base. 相似文献

We report four cases of communicating hydrocephalus, requiring shunt placement, in the subset of patients whose ventricles were breached at the time of glioma resection (a total 97 cases over 3 years). The hydrocephalus in these cases presented without ventricular dilatation on computed tomography (CT) scanning, and in 3 cases without headache. Failure to progress, visual deterioration or cerebrospinal fluid (CSF) leak in the post-operative patient after tumour resection with ventricular opening should alert clinicians to the possibility of hydrocephalus, despite the absence of headache or ventriculomegaly, and lumbar puncture should be performed without delay. 相似文献

Chronic cerebrospinal fluid (CSF) leaks associated with skull base fractures are rare but intractable and patients may be subjected to numerous operations. We present a 30-year-old man with a 13-year history of chronic CSF rhinorrhea following a cranial trauma. Computed tomography (CT) showed a bone defect in the planum sphenoidale. CT cisternography revealed a leak from the defect and CSF malabsorption. The absence of symptoms of CSF malabsorption may be attributable to external leakage of excess CSF. After closing the leak via the extended transsphenoidal approach we placed a ventriculoperitoneal shunt for occult hydrocephalus. We discuss the clinical symptoms of chronic CSF leakage and present therapeutic strategies dictated by the mechanisms underlying the leak. 相似文献

BACKGROUND: The efficacy of BioGlue (CryoLife, Inc, Atlanta, Ga) surgical adhesive in transsphenoidal surgery was assessed as an adjunct in the prevention of postoperative CSF leaks. METHODS: All patients in whom BioGlue was used for an intraoperative skull base reconstruction were retrospectively identified. Intraoperative CSF leaks were graded according to size (grade 1, small weeping leak without obvious diaphragmatic defect; grade 2, moderate leak with a definite diaphragmatic defect; grade 3, large diaphragmatic and/or dural defect). CSF leak repair was tailored to CSF leak grade. BioGlue was applied as a reinforcement over collagen sponge as the last layer of the repair. RESULTS: Over 28 months, a total of 282 patients underwent endonasal surgery. Of these patients, 124 (79 women; age range, 8-84 years), in 128 procedures, had an intraoperative CSF leak repair reinforced with BioGlue. Pathology included 80 pituitary adenomas, 11 craniopharyngiomas, 7 Rathke's cleft cysts, 6 chordomas, 5 meningiomas, 4 spontaneous CSF leaks, 3 arachnoid cysts, and 8 other parasellar pathologies. There were 62 (48.4%) grade 1, 41 (32.0%) grade 2, and 25 (19.5%) grade 3 leak repairs. The overall repair failure rate was 1.6% (2 cases), with the failures occurring in patients with grade 3 leaks, including 1 who developed meningitis; there was no failure of grades 1 and 2 leaks. The 2 failures were attributed largely to technical aspects of the repair rather than to failure of BioGlue per se. CONCLUSIONS: BioGlue appears to be an effective adjunct in preventing postoperative CSF leaks after transsphenoidal surgery. However, careful attention to technical details of the repair is still required to prevent failures, especially when closing large dural and diaphragmatic defects. 相似文献

Objective: To describe and assess the repair technique and perioperative management for cerebrospinal fluid (CSF) leak resulting from extensive anterior skull base fracture via extradural anterior skull base approach.
Methods: This was a retrospective review conducted at the Department of Neurosurgery of the Shanghai Tenth People''s Hospital from January 2015 to April 2020. Patients with traumatic CSF rhinorrhea resulting from extensive anterior skull base fracture treated surgically via extended extradural anterior skull base approach were included in this study. The data of medical and radiological records, surgical approaches, repair techniques, peritoperative management, surgical outcome and postoperative followup were analyzed. Surgical repair techniques were tailored to the condition of associated injuries of the scalp, bony and dura injuries and associated intracranial lesions. Patients were followed up for the outcome of CSF leak and surgical complications. Data were presented as frequency and percent.
Results: Thirty-five patients were included in this series. The patients’ mean age was 33 years (range 11-71 years). Eight patients were treated surgically within 2 weeks; while the other 27 patients, with prolonged or recurrent CSF rhinorrhea, received the repair surgery at 17 days to 10 years after the initial trauma. The mean overall length of follow-up was 23 months (range 3-65 months). All the patients suffered from frontobasal multiple fractures. The basic repair tenet was to achieve watertight seal of the dura. The frontal pericranial flap alone was used in 20 patients, combined with temporalis muscle and/or its facia in 10 patients. Free fascia lata graft was used instead in the rest 5 patients. No CSF leak was found in all the patients at discharge. There was no surgical mortality in this series. Bilateral anosmia was the most common complication. At follow-up, no recurrent CSF leak or meningitis occurred. No patients developed mucoceles, epidural abscess or osteomyelitis. One patient ultimately required ventriculoperitoneal shunt because of progressive hydrocephalus.
Conclusion: Traumatic CSF rhinorrhea associated with extensive anterior skull base fractures often requires aggressive treatment via extended intracranial extradural approach. Vascularized tissue flaps are ideal grafts for cranial base reconstruction, either alone or in combination with temporalis muscle and its fascia—fascia lata sometimes can be opted as free autologous graft. The approach is usually reserved for
patients with traumatic CSF rhinorrhea in complex frontobasal injuries. 相似文献

Recently, laparoscopy (also referred to as minimally invasive surgery) has been used during peritoneal catheter implantation in shunt placement for hydrocephalus; however, the procedure and devices for this technique have not yet been well established. We adopted umbilical and paraumbilical laparoscopy for peritoneal catheter insertion. In this paper, we describe the technique we used and its clinical results and benefits. Ten consecutive patients with hydrocephalus who underwent laparoscopic shunt surgery (6 cases of ventriculoperitoneal shunt and 4 of lumboperitoneal shunt) were enrolled for this study. The follow-up period ranged from 21 to 434 days (mean, 263 days). After a standard cranial/spinal procedure, an approximately 5-mm incision was made in the lateral side of the umbilicus, where the abdominal catheter was introduced subcutaneously. Thereafter, we inserted a laparoscope into the peritoneal cavity via a small incision beneath or just on the umbilicus. A shunt catheter was laparoscopically inserted through a peel-off cannula and placed after taking note of the outflow of cerebrospinal fluid (CSF) from the catheter tip. In all patients, the shunt was inserted with no complications, and good patency was achieved. Laparoscopy allows implantation of the catheter into the peritoneal cavity, and the outflow of CSF can be confirmed intraoperatively. Furthermore, the abdominal surgical wounds are minimal, even for obese patients, and fascia/muscle incisions are not needed. Laparoscopy-assisted shunt surgery for hydrocephalus is effective and safe and also has cosmetic advantages. 相似文献

In standard techniques for performing ventriculoperitoneal shunts, the peritoneal catheter is threaded more or less blindly into the peritoneal cavity. Using laparoscopic techniques allows accurate peritoneal placement, without a large incision, even in replacement procedures and in patients with previous abdominal operations. We performed 28 laparoscopically guided ventriculoperitoneal shunt placements and shunt revisions in 24 patients with hydrocephalus (aged 6-80 years). Sixteen of 24 patients (67%) had previous abdominal surgery. Laparoscopic shunt placement was successful in all patients. Mean operative time was 63 +/- 34.9 minutes (range 15-150 minutes). In 2 patients, broken and disconnected distal parts of previously inserted shunts were removed from the abdomen. One shunt was removed following infection and other one was revised due to shunt malfunction. Three patients required revision of the cranial part of the shunt. Laparoscopically guided distal ventriculoperitoneal shunt placement provides definite patient benefits: it allows shunt placement under direct vision, associated with reduced trauma to the abdominal wall, and avoids a consequent risk of intra-abdominal adhesions. 相似文献

Rhabdoid meningioma (RM) is a recently described, aggressive variant of meningioma. The authors report a case of RM occurring in the resection cavity of an unrelated neurosurgical procedure, temporal lobectomy for intractable seizures. The patient presented with intractable headache 10 years after the temporal lobectomy. Imaging revealed a dura-based, uniformly enhancing lesion within the resection cavity. She underwent gross-total resection and the findings of the surgical pathological report were consistent with an RM, with a dramatically elevated MIB-1 index of approximately 50%. The patient's clinical course was complicated by severe pain and communicating hydrocephalus secondary to rapid dissemination of malignant cells throughout the CSF pathways. Despite aggressive measures, including tumor resection, ventriculoperitoneal shunt placement, and the initiation of conventional radiation therapy, the ensuing leptomeningeal carcinomatosis proved to be rapidly fatal. 相似文献
