Objective To compare the therapeutic effect of one-stage direct revascularization and medicine therapy for the treatment of ischemic moyamoya disease. Methods From March 2002 to March 2008, 18 patients with ischemic moyamoyadisease (12 males and 6 females) were treated, aged 9 to 33 years old. Eighteen patients presented with ischemic stroke, including 11 cases of cerebral infarction and 7 cases of transient ischemic attack. According to Chinese ischemic cardiovascular diseases evaluation tools, 17 patients were classified as low risk ischemic stroke and 1 as modernte risk ischemic stroke. Different levels of occlusion branch of the intracranial carotid arteries and pathosis collaterals were identified by DSA. Fourteen patients and 4 patients were showed unilateral and bilateral hypoperfusion of cerebral blood flow by single photon emission computed tomography, respectively. Eleven patients received superficial temporal artery-middle cerebral artery anastomosis and 7 patients received medicine (anti-PLT agglutinin and calcium channel blocker). Results All incisions healed at stage I. There was no stroke events during perioperation. Anastomosis vessel vasospasm occurred in 2 patients 5 days after operation; and hyperperfusion syndrome in 1 patient 2 weeks afteroperation. All patients were followed up 13-32 months (mean 18 months). In 11 anastomosis patients, 6 underwent 6 stroke events within 12 months; in 7 medicine patients, 6 underwent 11 stroke events within 12 months; and showing a significant difference (P lt; 0.05). The stroke recurrence rate was 85.7% in medicine patients and 54.5% in anastomosis patients 12 months after therapy. DSA showed pathosis collaterals in 7 anastomosis patients and 6 medicine patients 6 months after therapy. After 12 months according to modified Rankin scale, the scores of anastomosis patients were 3 points in 1 case, 2 points in 6 cases and 0-1 point in 4 cases, and the scores of medicine patients were 2 points in 2 cases and 0-1 point in 5 cases; showing no significant difference (P gt; 0.05). Conclusion As long as onset of stroke occurred and ischemic moyamoya disease is diagnosed, one-stage direct revascularization should be performed, which can reduce the rate of stroke recurrence risk and slow down the progression of disease.
Objective To investigate the therapeutic effects of endovascular covered stent on vertebral dissecting aneurysm and carotid-cavernous fistula (CCF). Methods From March 2006 to May 2007, Jostent coronary stent grafts were used to treat 4 patients with vertebral dissecting aneurysm and 3 patients with CCF. The patients of vertebral dissecting aneurysmwere male and 37-57 years old, the lesion was located on the left vertebral artery in 3 patients and on the right vertebral artery in 1 patient, with the primary symptoms of sudden headache and vomiting; CT scan demonstrated subarachnoid hemorrhage; and the medical history varied from 2 days to 10 years. The patients of CCF were male and 35-51 years old, the lesion was located on the left carotid artery in 2 patients and on the right carotid artery in 1 patient, with the primary symptoms of headache, lateral exophthalmos, eyeball distending pain, conjunctive hyperemia and impaired eyesight; all 3 patients got head injury 2 days to 1 month before the appearance of symptoms and 1 of them had a history of severe nosebleed; and the medical history ranged from 1 week to 2 months. Results For the patients with vertebral dissecting aneurysm, complete obl iteration of aneurysms was achieved, the circulations of the vertebral artery, the adjacent posterior inferior cerebellar artery and the adjacent anterior inferior cerebellar artery were smooth, no compl ications relative to operation occurred, and no recurrence of symptoms and intracranial rehaemorrhagia were observed during the follow-up period of 8 months-2 years. For the patients with CCF, the fistula were completely obl iterated, the circulation of carotid artery was smooth, the exophthalmus and conjunctiva hyperemia were improved obviously 3 days after operation, the eyesight of patient was improved at different levels over the follow-up period of 1-3 months. Conclusion Endovascular covered stent is a new and useful tool for the treatment of vertebral dissecting aneurysm and CCF .
Objective To study the methods and techniques of the treatment forextensive suprasellar pituitary adenona and repairing hole.Methods From Feb. 2001 to Mar. 2003, 9 patients with exrensive suporasellar pituitary adenoma underwent resection via suprabital keyhole with endoscope-assisted microneurosurgery. Then the remaining tumor was removed with neuroendoscope via Ⅰand Ⅱ space of optic chiasma. The small bone flap was fixed with Ti clamp. Results After the tumor was removed with microneurosurgery, the remaining tumor was still found with endoscope in 7 cases. Remaining tumor was totally removed in 6 cases, almost removed in 3 cases. The vision improvement was found in 7 cases one week after surgery. In the other 2 cases, the vision remained unchanged. Follow-up was conducted in 6 cases for 6 to 22 months. Neuroradiological recovery of MRI with no recurrence of tumor was observed. No complication of incision was present. Conclusion Enough intra and extra-cranial space can be provided to operate via orbital roof approach to sellar tumors. Endoscope-assisted microneurosurgery can increase the total-resection and successful rate treatment for extensive suprasellar pituitary adenoma, reduce the possibility of complication, and pretect the function of brain from being injured. Fixation of small bone flap with Ti clamp is safe, easy and reliable.

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.
