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.
Objective To investigate the clinical characteristics and risk factors of immature hematomas in patients with primary intracerebral hemorrhage. Methods Patients with primary intracerebral hemorrhage who admitted in West China Hospital of Sichuan University between March 2012 and January 2021 were retrospectively analyzed. Brain CT scan was used to evaluate the presence of immature hematomas, as well as hematoma volume and the morphological features such as the number of hematoma projections or satellite foci, and finger-like projections. Imaging markers of cerebral small vessel disease such as lacunes, microbleeds, white matter hyperintensities (WMH), and enlarged perivascular space were evaluated on MRI. Mature hematomas were defined when the hematomas were completely homogeneous, without any irregularity or hypodensity, otherwise the hematomas were regarded as immature. Patients were divided into two groups: mature hematomas and immature hematomas. Multivariate Logistic regression was used to analyze the risk factors of immature hematomas. Results A total of 170 patients were included. Among them, there were 121 males (71.2%). The average age was (60.9±13.3) years old, and 129 cases (75.9%) had immature hematomas. The comparison between the mature hematomas group and the immature hematomas group showed that higher admission National Institutes of Health Stroke Scale score, larger hematoma volume, hematoma volume >30 mL, more hematoma projections or satellite foci, lower incidence of round or oval hematomas, cerebral small vessel disease score, lower WMH burden, and lower burden of cerebral small vessel disease were associated with the occurrence of immature hematomas. The results of multiple logistic regression analysis showed that lower incidence of round or oval hematomas, lower incidence of WMH, and lower periventricular WMH scores were associated with the occurrence of immature hematomas after adjusting for age, gender, hypertension, diabetes, smoking, alcohol consumption, admission National Institutes of Health Stroke Scale score, and hematoma volume. Conclusion Lower incidence of round or oval hematomas and lower periventricular WMH burden are associated with immature hematomas.

Methods: Intracerebral hemorrhage was induced in rats by injection of bacterial collagenase into the caudate nucleus. Histopathological changes were studied in 6 h,12 h, 24 h, 2 d, 3 d, 5 d, 7 d after the injection. The immunohistochemistry and TUNEL analysis were performed. The expression of complement factor C3, the TUNELpositive cells, the proapoptotic gene expression (Bax) and the antiapoptotic gene (Bclxl) were examined. Results: The expression of C3 increased to its maximum between 2448 h. The TUNELpositive cells and Bax protein expression increased gradually and reached the peak level between 4872 h. The Bclxl protein reached the peak level at 48 h. The correlation analysis showed that the quantity of C3 was positively related to that of the TUNELpositive cells, but the bax protein was not related to Bclxl protein. Conclusion: The expression of complement factor C3 may contributes to the nerve injury after cerebral hemorrhage and relate to the apotosis in the tissues surrounding the hametoma in rats.
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.
Cerebral small vessel disease refers to a group of pathological processes, neuroimaging features, and clinical symptoms, with various etiologies that affect the small arteries, arterioles, venules, and capillaries of the brain. The onset of cerebral small vessel disease can be insidious. It has various symptoms, some of which can attack acutely. Acute cerebral small vessel disease is characterized by lacunar stroke and brain parenchymal hemorrhage. The latter mainly includes hypertensive hemorrhage and cerebral amyloid angiopathy. This article summarizes the research advances of acute cerebral small vessel disease from the aspects of pathogenesis, clinical manifestations, neuroimaging features, and treatment methods, discussing characteristics and clinical challenges.
Stroke with hereditary cerebral small vessel diseases is a rare disease. Its clinical manifestations include early-onset ischemic lacunar or hemorrhagic stroke with high disability. Its typical imaging markers include lacunes, white matter hyperintensities, microbleeds, intracerebral hemorrhages located in deep or lobe of brain, crotical microinfarcts, and enlarged perivascular spaces. As the clinical and neuroimaging signs and symptoms of hereditary cerebral small vessel diseases often overlap with sporadic cerebral small vessel diseases, it is hard to diagnose. This article summarizes the clinical features, importance of obtaining valuable family history, genetic diagnosis, and management of stroke with hereditary cerebral small vessel disease to improve its accuracy diagnosis.
ObjectiveTo systematically review the efficacy between key hole approach versus large trauma craniotomy for patients with hypertensive intracerebral hemorrhage.
MethodsSuch databases as The Cochrane Library (Issue 3, 2013), PubMed, EMbase, WangFang Data, CNKI and VIP was searched to identify randomized controlled trials (RCTs) on key hole approach versus large trauma craniotomy for patients with hypertensive intracerebral hemorrhage from January 2005 to June 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2.
ResultsA total of 13 studies involving 1 324 patients was included. The results of meta-analysis showed that, key hole approach was superior to large trauma craniotomy with significant differences in the fatality rate (OR=0.29, 95%CI 0.19 to 0.45, P < 0.000 01), incidence of postoperative complications (OR=0.35, 95%CI 0.21 to 0.57, P < 0.000 1), recovery time of consciousness (MD=-4.52, 95%CI-5.84 to-3.20, P < 0.000 01), neurologic impairment score after 1-month treatment (MD=-12.63, 95%CI-16.36 to-8.90, P < 0.000 01), total effectiveness (OR=3.79, 95%CI 2.54 to 5.66, P < 0.000 01), and postoperative living ability (ADL Grade I, Ⅱ).
ConclusionKey hole approach is better than large trauma craniotomy for patients with hypertensive intracerebral hemorrhage. Due to limited quality and quantity of the included studies, the abovementioned conclusion still needs to be verified by conducting more high quality studies, especially conducting multicenter blinding RCTs with large sample-size.
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.
