Objective To analyze the trends in the burden of intracerebral hemorrhage (ICH) and its related risk factors in China from 1990 to 2021, providing evidence for targeted prevention and control. Methods Based on public data from the Global Burden of Disease Study 2021, four epidemiological indicators, including incidence, prevalence, deaths, and disability-adjusted life-years (DALYs) were selected to describe the burden of ICH in China in 2021. Change rates and estimated annual percentage changes (EAPC) were calculated to evaluate the trends in disease burden from 1990 to 2021. The Das Gupta method was used to decompose the effects of population growth, population aging and epidemiological changes on the burden during this period. Finally, the attributable burden of risk factors related to ICH was analyzed. Results In 2021, the age-standardized incidence, prevalence, mortality, and DALY rates of ICH in China were 61.2/100000, 222.1/100000, 68.8/100000, and 1351.6/100000, respectively, all higher than global estimates. From 1990 to 2021, although these rates showed a declining trend (EAPC: −2.24, −1.26, −2.38, and −2.47, respectively), the absolute disease burden, including the absolute number of incidence cases, prevalence cases, deaths, and DALYs, continued to rise, with an increase ranging from 20.57% to 51.59%. In addition, the burden of ICH in China varied by age and sex, with older adults and males experiencing a higher burden. Decomposition analysis indicated that population aging and growth were the primary drivers of the increasing ICH burden in China, while epidemiological changes mitigated this trend. Metabolic factors were the predominant attributable risk factors for ICH. High systolic blood pressure, ambient particulate matter pollution, and diet high in sodium were important risk factors common to both genders. The DALY burden attributable to smoking and alcohol use was higher in men, whereas impaired kidney function and secondhand smoke had a greater impact on women. Conclusions The burden of ICH in China has continued to increase from 1990 to 2021, and it may further escalate in the context of population aging. Risk factor control remains a key priority for prevention. Future strategies should incorporate age- and sex-specific interventions to reduce the ICH burden in China.
Objective To assess the results of microvascular decompression (MVD) in treating cranial nervehyperactive dysfunction. Methods From October 2002 to January 2007, 106 patients with cranial never hyperactivedysfunction were treated with MVD. Among them, there were 47 males and 59 females with an average age of 62 years (42-85 years), including 56 cases of trigeminal neuralgia, 33 cases of hemifacial spasm and 17 cases of spasmodic torticoll is. MRI showed obvious nerve root compression in 60 patients (56.6%), suspected nerve root compression in 33 patients (31.1%) and no nerve root compression in 13 patients (12.3%). The disease course was 2-300 months with median course of 54 months. The typical manifestations before operation were pain and myospasm in corresponding innervation region. Results The superior cerebellar artery was the most common offending vessel in trigeminal neuralgia (44.6%, 25/56), the anterior inferior cerebellar artery in hemifacial spasm (33.3%, 11/33), and the vertebra-basilar artery in spasmodic torticol is (82.4%, 14/17). Compl ications of facial paralysis, hypoacusia, facial numbness, dizziness, pain of neck and shoulder, muscles weakness of neck and subcutaneous dropsy occurred in 31 patients (29.2%). All patients were followed up for 6-42 months. The total response rate was 90.6%. The curative rate of MVD was 83.9% (47/56) in trigeminal neuralgia, 81.8% (27/33) in hemifacial spasm and 41.2% (7/17) in spasmodic torticol is, respectively. Five patients failed to response (4.7%), 2 of them were cured after re-operation and 3 abandoned further treatrment. Five patients suffered recurrence 3-8 months after operation (4.7%), 2 of them recovered after re-operation, 1 got rel ief by Gamma-knife treatment, and 2 abandoned further treatment. Conclusion MVD has a good therapeutic effect on the disease caused by vascular compression of cranial nerve. Comprehensive preoperative evaluation, skillful operational technique and intraoperative electrophysiological monitoring should be implemented to enhance the therapeutic effects of MVD and to prevent possible compl ications.
As the intensity of clinical and research work is high, teaching is gradually paid less attention to and the quality of education cannot be ensured. In this context, a full-time teaching position is set up in West China Hospital which is taken responsibility by qualified clinicians, to improve the teaching quality by strict management and omni-directional teaching. We introduce the setting and running of the full-time teaching position in West China Hospital in this paper.
ObjectiveTo explore the changes of intraoperative temperature and influencing factors of the short-term prognosis of patients undergoing clipping of posterior communicating artery aneurysms.MethodsThe basic clinic data and intraoperative temperature of patients undergoing elective clipping of posterior communicating artery aneurysms between October 2018 and July 2019 were collected, and the minimum intraoperative temperature was categorized into ≥36.0 and <37.5℃, ≥35.0 and <36.0℃, and <35.0℃. According to the Glasgow outcome scale (GOS) at discharge, the patients were divided into good prognosis group (GOS 4-5) and bad prognosis group (GOS 1-3). Multiple logistic regression analysis was used to obtain the risk factors of short-term prognosis.ResultsA total of 127 cases were involved, and intraoperative hypothermia (<36.0℃) occurred in 64 cases (50.4%). The intraoperative temperature presented classical three-phrase changes, i.e. it dropped rapidly at 1 hour after anesthesia introduction, decreased slowly during 2-3 hours after anesthesia introduction, and then entered the plateau. In the 127 cases, 93 (73.2%) had good prognosis, with an intraoperative hypothermia proportion of 44.1% (41/93); and 34 (26.8%) had bad prognosis, with an intraoperative hypothermia proportion of 67.6% (23/34). Univariate analysis showed that Hunt-Hess grade (χ2=18.999, P<0.001), intraoperative bleeding (χ2=7.074, P=0.008), minimum intraoperative temperature (Z=−3.473, P=0.001), and postoperative complications (χ2=43.060, P<0.001) were related to the short-term prognosis of patients undergoing clipping of posterior communicating artery aneurysms. Multiple logistic regression analysis presented that high Hunt-Hess grade (Ⅳ, Ⅴ) [odds ratio (OR)=6.456, 95% confidence interval (CI) (1.141, 36.532), P=0.035], the minimum intraoperative temperature <35.0℃ [OR=7.552, 95%CI (1.450, 39.345), P=0.016], and postoperative complications [OR=22.866, 95%CI (6.778, 77.142), P<0.001] were independent risk factors of the short-term prognosis. The difference in short-term prognosis between patients with the minimum intraoperative temperature ≥35.0 and <36.0℃ and the ones with the minimum intraoperative temperature ≥36.0 and <37.5℃ was not statistically significant (P>0.05).ConclusionsThe minimum intraoperative temperature<35.0℃ and postoperative complications were changeable factors to effect progonosis of patients undergoing elective clipping of posterior communicating artery aneurysms. Clinical staff should set medical intervention measures based on the individual conditions of patients to improve patients’ quality of life.
ObjectiveTo investigate the effect of microsurgical therapy and the key techniques in resection of large bilateral olfactory groove meningiomas via unilateral subfrontal approach.MethodsThe clinical data and follow-up results of 181 patients with large bilateral olfactory groove meningiomas who underwent microsurgical removal between June 2007 and May 2014 were retrospectively analyzed. The initial symptom was headache or (and) dizzy in 95 cases, hyposmia or anosmia in 53, impairment of visual function or (and) visual field deficits in 26, cognitive deficits in 3, epilepsy in 2, and accidentally discovered in 2. Unilateral subfrontal approach was applied in all patients (neuroendoscopy was applied in some cases in the later period); incision of falxcerebri, and when necessary, ligation of superior sagittal sinus to resect contralateral tumor were performed. Simultaneous or staged period resection of tumors invading skull base such as ethmoid sinus and superior meatus and reconstruction of the skull base were performed.ResultsThere was no perioperative mortality. Simpson grade Ⅰ resection was obtained in 33 cases, grade Ⅱ resection was in 141, grade Ⅲ resection was in 4, and grade Ⅳ resection was in 3. Among the 229 eyes with preoperative visual impairment, postoperative visual improvement was found in 215 eyes, unimproved was in 12, and aggravation was in 2. The 59 sides which lost their function of olfactory nerve before surgery obtained no recoveries after surgery, while olfactory nerve with residual function preoperative still kept sensing after surgery in 149 lateral sides (149/303). The patients were followed up for (76.9±43.8) months, and postoperative recurrence or residual tumor growth were found in 21 cases.ConclusionsBecause of the contralateral ocular and (or) nasal compensation, early discovery is very difficult for patients with olfactory groove meningioma. The unilateral subfrontal approach can provide sufficient exposure for resection of large bilateral olfactory groove meningiomas and improve the visual acuity and visual field deficits. But it is poor at the preservation of olfactory function. The approach, better with the aid of neuroendoscopy, can improve the total cutting rate, with the advantages of minimally invasion and fewer complications. It is a worthy priority for these tumors.
Objective To discuss the treatment of craniocerebral injuries caused by earthquake. Methods Retrospective analysis of clinical information for 256 patients with craniocerebral injury caused by an earthquake. Results The ‘Classification and Treatment’ was applied to the patients, whether or not they were operated on. A total of 146 patients were cured, 68 improved, 24 remained dependent on the care of others, and 8 died. The mortality rate was 3.13%. Conclusion Applying the ‘Classification and Treatment’ to patients with craniocerebral injury following an earthquake supported the use of medical resources and was associated with a low rate of death and disability.
Massive cerebral infarction with malignant brain edema has poor prognosis with very high mortality, despite aggressive medical treatment. Surgical decompression is recommended by Chinese and international clinical guidelines for patients with massive cerebral infarction, however, there is no standardized diagnosis and treatment protocol in clinical practice. Following the principle of evidence-based medicine and based on the diagnosis and treatment norms of the participating hospitals of Severe Ischaemic Stroke Collaboration in recent years, we recommend this consensus statement of the standardized surgical decompression for malignant brain edema in massive cerebral infarction.
