ABSTRACT
Objective:To compare the effect of middle meningeal artery embolization (MMAE) versus conventional therapy for chronic subdural hematoma (CSDH).Methods:Retrospective analysis of 38 patients with 48 CSDHs treated with MMAE from May 2019 to May 2021 was performed. Comparisons were made with a conventional treatment for 126 patients with 126 CSDHs from January 2016 to May 2021. The MMAE and conventional treatment patients were matched by the propensity score matching method, and a total of 25 pairs of patients (31 pairs of CSDHs) were successfully matched. The CSDH recurrence, rescue treatment, radiographic follow-up outcome, clinical improvement and complication between the two groups were compared by t test, χ 2 test or Fisher exact probability methods. Results:The rescue treatment rate in MMAE group was significantly lower than that in conventional treatment group [0 (0/31) vs 19.4% (6/31), P=0.024] and the complete resolution rate at 6 months follow-up in MMAE group was significantly higher than that in conventional treatment group [96.8 (30/31) vs 74.2% (23/31), P=0.026]. In terms of CSDH recurrence, there was a trend of lower recurrence in the MMAE group [3.2%(1/31) vs 22.6% (7/31), P=0.053]. The complete resolution rate at 3 months follow-up was 61.3% (19/31) in MMAE group and 45.2% (14/31) in conventional treatment, clinical improvement rate was 92.0% (23/25) in MMAE group and 88.0% (22/23) in conventional treatment, good outcome rate (mRS≤2) was 92.0% (23/25) in MMAE group and 84.0% (21/25) in conventional treatment, complication rate was 0(0/25) in MMAE group and 4.0% (1/25) in conventional treatment, and there were no significant differences in all above-mentioned parameters ( P>0.05). Conclusions:The MMAE may be considered as a safe and effective treatment for CSDH, and MMAE for CSDH is associated with lower trend of recurrence, lower rescue treatment rate and better radiographic follow-up outcome than conventional therapy.
ABSTRACT
Chronic subdural hematoma (CSDH) is a common neurosurgical disease, especially in elderly patients, and its treatment currently includes medication conservation, surgical intervention and combination therapy. Although many cases have achieved good results through drug treatment, as far as the present situation is concerned, surgical intervention is still an irreplaceable treatment, especially for patients with large amounts of hematoma, even those with cerebral hernia or recurrence. However, there are many surgical methods about CSDH, the clinical selection is controversial, what is more, there has been some progress in minimally invasive surgery in recent years. In this paper, the surgical methods of CSDH are summarized as follows. The purpose is to provide for clinical evaluation and selection.
ABSTRACT
Objective To investigate the efficacy of neuroendoscopy combined with urokinase in the treatment of spontaneous intraventricular hemorrhage.Methods From August 2014 to August 2017,91 spontaneous thalamic hemorrhage ruptured into ventricles patients in Affiliated Hospital of the Yangzhou University were enrolled,who were underwent surgical treatment in this retrospective study.The patients were divided into the study group(n =41) and control group(n =50) based on different methods of treatment.The patients in the study group were given with remove visible intraventricular hematoma by neuroendoscopy,followed by External Ventricular Drainage (EVD) combined with urokinase fibrinolysis.The patients in control group were given with EVD combined with urokinase fibrinolysis.The time of postoperative drainage,ICU stay,duration of onset of fever,the number of intracranial infections,and the proportion of Glasgow outcome scale (GOS) (1 to 5) at 6 months postsurgery were compared between two groups.Measurement data were expressed as (Mean ± SD),and t test was used for measurement data.The count data were analyzed by x2 test or nonparametric rank sum test.Results The time of postoperative drainage,the number of intracranial infections,ICU stay in study group were (6.19 ± 1.1) d,5 cases,(2.8 ± 1.6) d,the indexes in control group were (7.06 ± 1.3) d,15 cases,(5.2 ± 2.0) d.The time of postoperative drainage,ICU stay,the number of intracranial infections were superior to those of the control group,and the difference was statistically significant.The proportion of GOS (1 to 5) at 6 months after surgery was 5 cases (12.2％),5 cases (12.2％),10 cases (24.4％),14 cases (34.1％),7 cases (17.1％) in study group,the indexes in control group were 10 cases(20.0％),13 cases (26.0％),11 cases(22.0％),10 cases(20.0％),6 cases(12.0％).The 6-month postoperative GOS of the study group were superior to those of the control group,and the difference was statistically significant (P ＜ 0.05).Conclusion Neruendoscopy combined with urokinase in the treatment of spontaneous intraventricular hemorrhage can reduce the time of postoperative drainage and the incidence of intracranial infection,shorten the time of ICU stay and improve the functional prognosis of the patients.
ABSTRACT
Objective To compare the effect of the bipolar electric coagulation and unipolar electric coagulation on cranioplasty of scalp separation. Methods The clinical data of 67 patients who underwent unilateral frontotemporal cranioplasty from 2014 to 2017 were retrospectively analyzed. According to coagulation method during operation, these patients were divided into two groups, unipolar electric coagulation group (32 cases) and bipolar electric coagulation group (35 cases). The operation time, postoperative intracranial hemorrhage, infection, epilepsy and subcutaneous effusion were compared between two groups. Results The operation time of two groups had no significant difference (P > 0.05). The incidence of intracranial hemorrhage, infection and epilepsy of two groups had no significant differences (P > 0.05). But the incidence of subcutaneous effusion in unipolar electric coagulation group was significantly higher than that in bipolar electric coagulation group: 28.1%(9/32) vs. 5.7%(2/35), P<0.05. Conclusions The use of unipolar electric coagulation during the scalp separation in cranioplasty can reduce operation time in a certain extent, but significantly increase the incidence of postoperative subcutaneous effusion.
ABSTRACT
Objective To evaluate the clinical effect of chronic subdual hematoma between surgical procedure twist drill craniostomy with injecting urokinase into hematoma space and only with twist drill craniostomy.Methods Two hundred and twenty-five patients with chronic subdual hematoma patients who were admitted in the Affiliated Hospital of Yangzhou University from January 2011 to April 2017 were retrospectively analyzed.They were divided into two groups according to the different surgical methods,group A for twist drill craniostomy with injecting urokinase into hematoma space (n =116),group B only for twist drill craniostomy (n =109).Then the postoperative drainage volume and residual hematoma was analyzed by repeated measures,while radiographic grading system and recurrence rates after operation were compared between groups with statistical analysis which was done by ANOVA analysis or non-parametric rank sum test.Results The drainage volume 48 hours after surgery was(52.41 ± 7.86) ml in group A,(28.42 ± 4.46) ml in group B as well.The residual volumes which were calculated at 1 month,3 months after surgery was (23.35 ±4.18) ml and (15.31 ±6.15) ml in group A,comparing the volumes of (46.07 ± 5.96) ml and (25.60 ± 5.03) ml in group B.The radiographic grading system was evaluated by grade 1-4.There were 75(64.7％) cases in grade 1,32(27.6％) cases in grade 2,8(6.9％) cases in grade 3,1 (0.9％) cases in grade 4 of group A,as well as 42(38.5％) cases in grade 1,55(50.5％) cases in grade 2,11 (10.1％) cases in grade 3,1 (0.9％) cases in grade 4 of group B.The rate of recurrence for chronic subdural hematoma was 6.0％ in group A,while it was 15.6％ in group B.These data all had significant statistical difference between the two groups (P ＜ 0.05).Conclusion Twist drill craniostomy might be a safe,effective and mini-massive method for treating chronic subdual hematoma,while injecting urokinase into the hematoma space could significantly reduce the rate of recurrence and decrease the volume of hematoma.
ABSTRACT
Objective To investigate the risk factors for clinical poor outcome after microsurgical treatment of ruptured middle cerebral artery aneurysms (MCAA).Methods The patients with ruptured MCAA treated with microsurgery were enrolled retrospectively.The data of demography,medical history,Hunt-Hess grade,imaging characteristics,surgery-related factors,and postoperative complications were collected.Glasgow Outcome Scale (GOS) was used to assess the outcomes.GOS 4-5 was defined as a good outcome and 1-3 was defined as a poor outcome.Results A total of 44 patients with ruptured MCAA were enrolled,including 26 (59.1％) females and 18 (40.9％) males,aged 36-75 years old (mean 58.5 years).The aneurysms were clipped in 42 cases (95.5％) and wrapped in 2 eases (4.5％).They were followed up for 3-6 months,33 (75.0％) had good outcome and 11 (25.0％) had poor outcome.Univariate analysis showed that there were significant differences in the proportions of Hunt-Hess grade,midline shift degree,hematoma volume,intraoperative rupture,decompressive craniectomy,and postoperative pulmonary infection between the good outcome group and the poor outcome group.Multivariatelogistic regression analysis showed that Hunt-Hess grade Ⅳ-Ⅴ (odds ratio [OR] 20.885,95％ confilence interval [CI] 1.342-38.696;P =0.001),intraoperative anenrysm rupture (OR 18.906,95％ CI 2.918-20.915;P=0.011),and complicated with pulmonary infection (OR 38.865,95％ CI 18.718-40.509;P =0.001) were the independent risk factors for poor outcomes.Conclusion The high Hunt-Hess grade,intraoperative aneurysm rupture,and complicated with pulmonary infection after surgery are the independent risk factors for poor outcomes after microsurgical treatment in patients with ruptured MCAA.
