ABSTRACT
Objective To investigate the advantage of neuronavigation assisted microsurgical resection of gliomas in eloquent areas of brain. Methods The clinical data of 99 patients with gliomas in eloquent areas of brain and underwent microsurgery in the First Affiliated Hospital of Sun Yat-sen University from January 2012 to December 2017 were analyzed retrospectively. All patients were divided into two groups: neuronavigator-guided microsurgery group (neuronavigation group,46 cases) and non-neuronavigator-guided microsurgery group (non-neuronavigation group,53 cases). The neuronavigation group received neuronavigation assisted microsurgery, while the non-neuronavigation group received general microsurgery. MRI examination, Karnofsky performance scale (KPS) score and symptomatic improvement rate were used to analyze the extent of resection and postoperative function. Results The total resection rate of neuronavigation group was 91.3% (42/46). Comparing with 73.6% (39/53) total resection rate in non-neuronavigation group,the difference of total resection rate was statistically significant (Z=-2.343,P＜0.05). The postoperative symptoms improved both in neuronavigation group and non-neuronavigation group,and the KPS score at discharge were higher than that before operation (P＜0.05). No aggravation of symptoms and signs or new complications occurred in all patients except one case of postoperative muscle strength decline in non-neuronavigation group after the surgery. According to tumor size,the total resection rate of neuronavigation group and non-neuronavigation group among patients whose maximum size of tumor≥3cm were 89.5%(34/38) and 72.5%(37/51) respectively. The difference of total resection rate was statistically significant between these two groups (Z=-2.040,P＜0.05). Conclusion Neuronavigation assisted microsurgical resection of gliomas in brain eloquent areas can improve the rate of total resection and postoperative quality of life without increase in postoperative complications.
ABSTRACT
Objective To investigate the operative efficacy of pellucid septostomy in patients with septum pellucidum cysts and refractory epilepsy.Methods Nine patients with septum pellucidurn cysts and refractory epilepsy,admitted to our hospital from January 2012 to September 2017,chosen;diagnosis by MR imaging was performed in all patients and no other obvious epilepsy lesions were noted.All patients underwent bilateral endoscopic fenestration (pellucid septostomy) by right frontal approach.Follow-up was performed for 6-72 months.Results All patients took antiepileptic regularly.No overall tonic-clonic seizure was noted in 6-72 months of follow-up.Shrunk septum pellucidum cysts were noted in MR imaging.Conclusion Patients with septum pellucidum cysts and refractory epilepsy could be cured by pellucid septostomy.
ABSTRACT
Objective To investigate the microsurgical effect of spinal cord Intramedullary cavernous hemangioma.Methods The clinical data of 23 patients with spinal cord Intramedullary cavernous henangioma from January,2003 to March,2017 were analyzed retrospectively.McCormick clinical neurological function classification method and MRI examination were used to analyze the changes of neurological function and imaging changes beforeand-after operation.MRI and assess nerve function were reviewed 6-12 months after discharge.Results Twentytwo cases were totally resected,and subtotal excised in 1 case.The symptoms improved and even disappeared completely in 17 cases.There was no obvious improvement in 4 cases,2 cases were worse and no death cases.Twentyone cases were followed-up.The follow-up time was 3 months-9 years,and no tumor recurrence was found.Among the 14 cases of clinical neurological function Ⅰ-Ⅱ,10 cases recovered rapidly and most of the symptoms improved or even disappeared.Three cases had no obvious change.The other 1 case aggravated symptoms;Six cases of Ⅲ-Ⅳ patients in 7 cases of postoperative recovery,and 1 case of no change.According to preoperative neurological function grade Ⅰ-Ⅱ and Ⅲ-Ⅳ,the treatment effect of patients was compared,the difference was significant (x2=5.25,P＜0.05).Conclusion Microsurgical resection of spinal cord Intramedullary cavernous hemangioma is safe and effective.The preoperative nerve function,the relationship between the tumor and the spinal cord,and the surgical skill and the degree of resection are the important factors that affect the prognosis.
ABSTRACT
Objective To investigate the effect of Mepilex on pressure sores in patients at lateral position after craniocerebral surgery.Methods Toally 60 patients lying at lateral position after craniocerebral surgery were randomized into two groups in equal number with random digit table:the control group and experiment group.In the control group,Gel pad was used to prevent and treat the pressure sores and in the experiment group Mepilex was used between the compressed skin and operation table before setting the position.The skin conditions of the two groups were observed after operation.Result The prophylactic effect of pressure sore in the experiment group was significantly better than that in the control group (P＜0.05).Conclusion Mepilex can prevent the skin pressure sores in the patients at lateral position after cerebral surgery.
