ObjectiveTo explore and compare the therapeutic effects of neuro-endoscopic and craniotomic hematoma evacuation for hypertensive hematomas in the basal ganglia region. MethodsEighty-six patients with hypertensive hematomas in the basal ganglia regions treated between January 2010 and September 2014 were divided into neuro-endoscopy and craniotomy groups randomly with 43 in each. Hematoma was removed directly under neuro-endoscope in the endoscopic group, while it was removed under the operating microscope in the craniotomy group. The average operation bleeding amount, residual hematoma after operation, hematoma evacuation rate, the changes of National Institutes of Health Stroke Scale (NIHSS) and Barthel index (BI) scores before operation, 1 and 3 months after operation were compared between the two groups. All data were analyzed statistically. ResultsThe average amount of operation bleeding was (127±26) mL, postoperative residual hematoma was (6±4) mL, and the hematoma clearance rate was (86±9)% in the neuro-endoscopy group, while those three numbers in the craniotomy group were respectively (184±41) mL, (11±6) mL, and (72±8)%, with all significant differences (P < 0.05). The NIHSS and BI scores were not significantly different between the two groups before surgery (P > 0.05). Seven days, one month and three months after surgery, the NIHSS score was significantly lower, and the BI score was significantly higher in the neuro-endoscopy group than the craniotomy group (P < 0.05). ConclusionNeuro-endoscopic surgery for hypertensive hematomas in basal ganglia region is proved to have such advantages as mini-invasion, direct-vision, complete clearance and good neural function recovery after surgery, which is a new approach in this field.
ObjectiveTo conduct an objective record of stroke patient’s retinal diseases by retinal photography, and analyze the incidence of various retinal diseases between different subtypes of stroke.MethodsFrom June to October 2007, the consecutive cases of stroke admitted to the Department of Neurology, West China Hospital of Sichuan University were prospectively registered. Ischemic stroke patients were classified into different subtypes by the Oxfordshire Community Stroke Project criteria, and intracerebral hemorrhage (ICH) patients were classified based on the clinical manifestation and neuroimaging. We collected other clinical data associated with the incidence of stroke. The retinal abnormalities including retinopathy, arteriovenous nicking and arteriolar narrowing were recorded. Multivariate logistic regression was performed to investigate the relationship between retinal abnormalities and stroke.ResultsThis study included 199 patients with ischemic stroke and 95 patients with ICH. Among the patients with ischemic stroke, 43 (21.6%) had retinopathy, 52 (26.1%) presented with arteriovenous nicking, and 43 (21.6%) developed arteriolar narrowing. Among the patients with ICH, retinopathy occurred in 23 (24.2%), arteriovenous nicking occurred in 14 (14.7%), and arteriolar narrowing occurred in 25 (26.3%). In multivariate analysis, retinopathy was independently associated with partial anterior circulation infarct (PACI) (P=0.029) and anterior ICH (P=0.041).ConclusionsRetinopathy is independently associated with PACI and anterior ICH. Further community-based study with large sample should be conducted to confirm the predictive value of retinal diseases on the incidence of anterior stroke.
Objective To investigate the etiological and clinical characteristics of 1298 cases with spontaneous intracerebral hemorrhage. Methods A retrospective analysis was conducted to investigate the epidemiology and clinical characteristics of 1298 patients who suffered from spontaneous intracerebral hemorrhage and were hospitalized in Neurology Dept. of Anhui Provincial Hospital from 2005 to 2009. Results Among 1 298 patients, 822 (63.33%) were male while 476 (36.67%) were female. The constituent ratio of male and female patients was significantly different; the patients mainly suffered from spontaneous intracerebral hemorrhage in winter and spring which was commonly caused by hypertension accounting for 65.87% and was mostly happened on basal ganglia site (n=895, 68.95%). Conclusions The incidence of spontaneous cerebral hemorrhage is related with age, season and hypertension, it is very important to be prevented effectively and to well control the blood pressure.
The incidence, mortality, and disability rate of spontaneous intracerebral hemorrhage (SICH) are high, and its surgical and medical treatment is still controversial. With the development of micro-neurosurgical technology, minimally invasive surgery (MIS) has made great progress in the treatment of SICH. It can remove intracerebral hematoma in the early stage after SICH and minimize or eliminate secondary brain injury, which is of great significance to reducing the mortality and disability rate. For many years, due to its continuous progress, MIS has been more and more widely used in the treatment of SICH. This article mainly reviews the progress of MIS in SICH and related clinical research at home and abroad, and briefly describes several innovative techniques related to MIS, which aims to promote the exchange of clinical experience in MIS of SICH.
Objective To determine whether fluoxetine, a commonly used selective serotonin reuptake inhibitors (SSRIs), could exacerbate bleeding in a intracerebral hemorrhage (ICH) mouse model. Methods Forty two 12-14 month old female specific pathogen free C57BL/6 mice were selected. Mice were randomly divided into fluoxetine group (fluoxetine pre-treatment) and control group, with 21 mice in each group. After treated with fluoxetine for 7 days, ICH was induced by injecting collagenase Ⅶ-S into the right striatum of middle-aged female mice. Effects of fluoxetine on exacerbating bleeding were evaluated by a combination of histologic, molecular, cellular, and behavioral assessments. Results On the third day after ICH, the hemorrhage volumes of the control group and fluoxetine group were (4.59±1.80) mm3 and (6.09±1.08) mm3, respectively. In middle-aged female mice subjected to collagenase-induced ICH, fluoxetine pre-treatment significantly exacerbated neurological deficit, cerebral hemorrhage volume, myelin damage, hemoglobin and iron deposition, neuronal degeneration, and brain edema (P<0.05). Although there was no significant difference in tail bleeding time between the two groups, fluoxetine pre-treatment might increase tail bleeding time [(276.73±211.06) vs. (438.00±236.79) s; t=?1.686, P=0.055]. Conclusions The use of fluoxetine and more generally of SSRIs, which inhibits platelet aggregation, may exacerbate bleeding after ICH. Thus, patients with depression after ICH may avoid concomitant use of such drugs when choosing an antidepressant.
ObjectiveTo systematically review the effectiveness and safety of intensive blood pressure lowering in intracerebral hemorrhage (ICH). MethodsRandomised controlled trials (RCTs) and quasi-RCTs about ICH patients receiving intensive blood pressure lowering were searched from PubMed, EMbase, SCIE, The Cochrane Library (Issue 2, 2013), CBM, CNKI, VIP and WanFang Data until March, 2014. Literature was screened according to the exclusion and inclusion criteria by two reviewers independently and meta-analysis was conducted using RevMan 5.2 software after data extraction and quality assessment. ResultsA total of 24 studies were included involving 6 299 patients, of which 10 were RCTs and 14 were quasi-RCTs. The results of meta-analysis showed that intensive blood pressure lowering was superior to guideline-recommended intervention in reducing 24-h hematoma expansion rates (OR=0.36, 95%CI 0.28 to 0.46, P < 0.05), 24-h hematoma expansion volume (MD=-3.71, 95%CI-4.15 to-3.28, P < 0.05) and perihematomal edema volume (MD=-1.09, 95%CI-1.92 to-0.22, P < 0.05). Meanwhile, intensive blood pressure lowering improved 21-d NIHSS score (MD=-3.44, 95%CI-5.02 to-1.87, P < 0.05). But there was no significant difference in mortality and adverse reaction between the two groups. ConclusionCurrent evidence shows that intensive blood pressure lowering could reduce hematoma expansion volume and perihematomal edema volume, which is beneficial to recovery of neurological function, but ICH patients' long-term prognosis needs to be further studied. Due to the limited quantity and quality of the included studies, high quality studies are needed to verify the above conclusion.
ObjectivesTo explore the efficacy and prognostic factors of neuroendoscopic intracerebral hematoma evacuation in the treatment of hypertension-related intracerebral hemorrhage.MethodsA total of 122 patients with hypertension-related intracerebral hemorrhage treated in our hospital from October 2015 to May 2019 were categorized into experimental group (n=62) and control group (n=60). The experimental group was treated with endoscopic intracerebral hematoma removal, while the control group was treated with traditional craniotomy. The operative indexes, postoperative recovery, serum endothelin, IL-6, CRP levels and the incidence of postoperative complications were observed and compared between the two groups, and the relevant factors affecting the prognosis of patients undergoing neuroendoscopic intracerebral hematoma evacuation were analyzed.ResultsThe operation time, intraoperative blood loss, hematoma clearance rate, ICU treatment time, the volume of brain edema 7 days after operation, the postoperative intracranial pressure, NIHSS score and ADL score in experimental group were significantly superior to those in control group. The levels of serum endothelin, IL-6 and CRP in the experimental group were significantly lower than those in the control group after operation. The incidence of complications in the experimental group was lower than that in control group. Univariate analysis showed that the prognosis of patients undergoing neuroendoscopic evacuation of intracerebral hematoma was significantly correlated with the history of hypertension, preoperative GCS score, the amount of bleeding and whether been broken into the ventricle (P<0.05), but not with age, sex and location of hemorrhage (P>0.05). Multivariate logistic regression analysis showed that the history of hypertension above 10 years, blood loss above 50 mL, intraventricular rupture and preoperative GCS score were the risk factors affecting the prognosis of patients undergoing neuroendoscopic intracerebral hematoma evacuation.ConclusionsCompared with traditional craniotomy, neuroendoscopic evacuation of intracerebral hematoma has the advantages of better curative effect and lower incidence of postoperative complications in the treatment of hypertension-related intracerebral hemorrhage. The history of hypertension above 10 years, bleeding volume above 50 mL, breaking into the ventricle and preoperative GCS score are the risk factors affecting the prognosis of patients undergoing neuroendoscopic intracerebral hematoma evacuation.
Resuming oral anticoagulant (OAC) after intracerebral hemorrhage (ICH) is still a dilemma to clinical decision. To date, no high-quality randomized controlled trials demonstrate the timing and mode of safely resuming OAC. In recent years, some moderate-quality researches have suggested that OAC resuming after ICH can decrease the incidence of thromboembolic events and long-term mortality, without significantly increasing the risk of ICH; it is safer to resuming OAC in patients with non-lobar ICH than in patients with lobar-ICH; new OACs are superior to vitamin K antagonists; patients with high thromboembolic risk should resume OAC 2 weeks or even earlier after ICH, otherwise, a time-window for optimal resumption is between 4-8 weeks; meanwhile, individual patient characteristics should be considered and blood pressure should be strictly controlled.
The real-time monitoring of cerebral hemorrhage can reduce its disability and fatality rates greatly. On the basis of magnetic induction phase shift, we in this study used filter and amplifier hardware module, NI-PXI data-acquisition system and LabVIEW software to set up an experiment system. We used Band-pass sample method and correlation phase demodulation algorithm in the system. In order to test and evaluate the performance of the system, we carried out saline simulation experiments of brain hemorrhage. We also carried out rabbit cerebral hemorrhage experiments. The results of both saline simulation and animal experiments suggested that our monitoring system had a high phase detection precision, and it needed only about 0.030 4s to finish a single phase shift measurement, and the change of phase shift was directly proportional to the volume of saline or blood. The experimental results were consistent with theory. As a result, this system has the ability of real-time monitoring the progression of cerebral hemorrhage precisely, with many distinguished features, such as low cost, high phase detection precision, high sensitivity of response so that it has showed a good application prospect.
This study aims to evaluate the ability of C-arm cone-beam CT to detect intracranial hematomas in canine models. Twenty one healthy canines were divided into seven groups and each group had three animals. Autologous blood and contrast agent (3 mL) were slowly injected into the left/right frontal lobes of each animal. Canines in the first group, the control group, were only injected with autologous blood without contrast agent. Each animal in all the 7 groups was scanned with C-arm cone-beam CT and multislice computed tomography (MSCT) after 5 minutes. The attenuation values and their standard deviations of the hematoma and uniformed brain tissues were measured to calculate the image noise, signal to noise ratio (SNR) and contrast to noise ratio (CNR). A scale with scores 1-3 was used to rate the quality of the reconstructed image of different hematoma as a subjective evaluation, and all the experimental data were processed with statistical treatment. The results revealed that when the density of hematoma was less than 65 HU, hematomata were not very clear on C-arm CT images, and when the density of hematoma was more than 65 HU, hematomata showed clearly on both C-arm CT and MSCT images and the scores of them were close. The coherence between the two physicians was very reliable. The same results were obtained with C-arm cone-beam CT and MSCT grades in measuring SD value, SNR, and CNR. The reasonable choice of density detection range of intracranial hematoma with C-arm cone-beam CT could be effectively applied to monitoring the intracranial hemorrhage during interventional diagnosis and treatment.
