Objective : Cerebrovascular disease (CVD) was the third most common cause of death in South Korea in 2014. Evidence from abroad suggests that comprehensive stroke centers play an important role in improving the mortality rate of stroke. However, surgical treatment for CVD is currently slightly neglected by national policy, and there is still regional imbalance in this regard. For this reason, we conducted a survey on the necessity of, and the requirements for, establishing regional comprehensive cerebrovascular surgery centers (CCVSCs). Methods : This investigation was performed using the questionnaire survey method. The questionnaire was consisted with two sections. The first concerned the respondent's opinion regarding the current status of demand and the regional imbalance of cerebrovascular surgery in South Korea. The second section asked about the requirements for establishing regional CCVSCs. We sent the questionnaire to 100 board members of the Korean Society of Cerebrovascular Surgeons. Results : Most experts agreed that cerebrovascular surgery patients were concentrated in large hospitals in the capital area, and 83.6% of respondents agreed that it was necessary to alleviate the regional imbalance of cerebrovascular surgery. With regards to personnel, over 90% of respondents answered that at least two neuro-vascular surgeons and two neuro-interventionists are necessary to establish a CCVSC. Regarding facilities, almost all respondents stated that each CCVSC would require a neuro-intensive care unit and hybrid operating room. The survey asked the respondents about 13 specific neurovascular surgical procedures and whether they were necessary for a regional CCVSC. In the questions about the necessity of cerebrovascular surgical equipment, all seven pieces of equipment were considered essential by all respondents. A further five pieces of equipment were considered necessary on site: computed tomographic angiography, magnetic resonance angiography, conventional angiography, surgical microscope, and surgical navigation. Our results may provide a basis for future policy regarding treatment of cerebrovascular disease, including surgery. Conclusion : Raising the comprehensiveness of treatment at a regional level would lower the national disease burden. Policies should be drafted regarding comprehensive treatment including surgery for cerebrovascular disease, and related support plans should be implemented.

Purpose of this study was to investigate correlation between blood pressure (systolic and diastolic) and dietary sodium, potassium intake pattern in the family members of normal cerebrovascular (CVA) disease, excluding patients themselves. Both mean values of systolic (125.8$\pm$23.7 vs 119.3$\pm$19.2mmHg) and diastolic(76.1$\pm$16.7 vs 71.6$\pm$12.5mmHg) bllood pressure in the family members of cerebrovascular disease patients were significantly higher than those of normal subjects. Systolic blood pressure was positively correlated with age, weibght, sodium in soybean paste, potassium in hotpepepr paste, soybean paste and meats in normal subjects group. In the family members of cerebrovascular patient, systolic blood pressure was possively correlated with age, weight, sodium in soy sauce, drinking water and potassium in soups. Interestingly, table salt intake was positively correlated with systosolic blood pressure in the family members of cerebrovascular disease patients. Diastolic bolld pressure was positively correlated with age, weight, table salt intake potassium in hotpepper paste and soybean paste in normal subjects group. Diastolic blood pressure was positively correlated with age, weight and table salt intake in the family members of cerebrovascular disease patients. Urinary potassium excretion was negatively correlated with both systolic and diastolic blood pressure in the family members of cerebrovascular disease patients.

BACKGROUND/OBJECTIVES: Unhealthy dietary behaviors constitute one of risk the factors for chronic and cardiovascular diseases, which are prevalent in middle-aged and older populations. Milk and dairy products are high-quality foods and important sources of calcium. Calcium protects against osteoporosis and cardiovascular disease. Therefore, this study investigated the association of milk and dairy product consumption with cardio-cerebrovascular disease incidence in middle-aged and older Korean adults. SUBJECTS/METHODS: Data were derived from the Ansan-Anseong cohort study, and a total of 8,009 individuals aged 40-69 years were selected and followed up biennially. Cox proportional hazard models were used to examine the association of milk and dairy product consumption with cardio-cerebrovascular disease incidence. RESULTS: During a mean follow-up period of 96.5 person-months, 552 new cases of cardio-cerebrovascular disease were documented. Milk consumers (< 1 serving/day) exhibited a 23% lower risk of cardio-cerebrovascular disease incidence than non-milk consumers (hazard ratio [HR], 0.77; 95% confidence interval [CI], 0.61-0.97; P for trend = 0.842). High yogurt consumption was associated with a 29% lower incidence risk (≥ 0.5 servings/day vs. none: HR, 0.71; 95% CI, 0.53-0.96; P for trend = 0.049), whereas high ice cream consumption was associated with a 70% higher risk of cardio-cerebrovascular disease incidence (≥ 0.5 servings/day vs. none: HR, 1.70; 95% CI, 1.01-2.88; P for trend = 0.070). CONCLUSIONS: This study indicates that less than one serving of milk and high yogurt consumption are associated with a lower cardio-cerebrovascular disease risk in the middle-aged and older populations.

Background: Cerebrovascular diseases are known to show different patterns of incidence among regions and races. Therefore, it is very important to determine the incidence pattern of a specific area in order to diagnose, treat and prevent cerebrovascular diseases. The objective of the present study is to analyze quantitatively the incidence ratios of hemorrhagic and ischemic cerebrovascular diseases by season, by gender and by age. Methods: The subjects of this study were 1603 patients hospitalized for hemorrhagic or ischemic cerebrovascular diseases at the Department of Neurosurgery or the Department of Neurology of a University Hospital. Statistical analysis of data used Excel 2003 of Microsoft, and t-test was conducted using ORIGIN 6.0 of MICROCAL. Results: In the subjects, the incidence ratios of hemorrhagic and ischemic cerebrovascular diseases for four years, the period of this research, were 38.55% and 61.45%, respectively. The mean and standard deviation of age when hemorrhagic cerebrovascular diseases occurred were 58.20 and 12.60, respectively, and the percentages of subjects in their 40s, 50s, 60s and 70s were all around 20%. On the contrary, the mean and standard deviation of age when ischemic cerebrovascular diseases occurred were 65.01 and 13.59, respectively. The average age of patients with ischemic cerebrovascular diseases was older than that of patients with hemorrhagic brain diseases, and the percentages of those in their 60s, 70s and 80s were 15.53%, 37.06% and 27.72%, respectively. The season when hemorrhagic cerebrovascular diseases appeared most frequently was winter, which was followed by summer, spring and autumn. The season when hemorrhagic cerebrovascular diseases appeared most frequently was spring, which was followed by summer, winter and autumn. Conclusions: In this study, the incidence rates of hemorrhagic and ischemic cerebrovascular diseases were 38.55% and 61.45%, showing the rising percentage of ischemic cerebrovascular diseases. For making adequate prevention and disease control plans, it is considered necessary to make a long-term epidemiological investigation of cerebrovascular diseases.

The purpose of this study was to utilize Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiography (MRA) to analyze intracerebral regional distributions (hot spot) of ischemic cerebrovascular diseases which were characterized by stenosis and occlusion cerebral vasculature, except for cerebrovascular diseases induced by rupture of cerebral vasculature in terms of Korean people's cerebrovascular diseases, so that it could apply the findings of analysis to clinical practices. This study focused only on analyzing intracerebral regional distributions of ischemic cerebrovascular diseases that are characterized by stenosis and occlusion cerebral vasculature, because there are different etiologic mechanisms of ischemic cerebrovascular diseases like hemorrhagic cerebrovascular diseases (caused by rupture of cerebral vasculature) and cerebral infarction (induced by atheromatous arteriosclerosis). As a result, this study could come to the following findings of analysis: 1. According to sex ratio analysis, it was found that male group comprised larger portion of total 626 subjects in this study than female one (55.0% > 45.0%). 2. According to analysis on actual intracerebral regional distributions of ischemic cerebrovascular diseases, it was found that most subjects (37.5 %) were attacked by such diseases on the right side of cerebral vasculature, which was followed by left side of cerebral vasculature (35.1%) and bilateral cerebral vasculature (27.3%) respectively. 3. According to analysis on actual intracerebral regional distributions of ischemic cerebrovascular diseases, it was found that internal carotid artery (ICA) comprised the largest portion (38.9%) of those distributions, which was followed by middle cerebral artery (MCA, 35.7%), posterior cerebral artery (PCA, 13.4%), anterior cerebral artery (ACA, 6.0%) and vertebral artery (VA, 3.3%) respectively. 4. It was found that there was no subject attacked by any disease on A-com region, and there was only one male subject attacked by cerebrovascular diseases on P-com region. 5. It was found that female group was more susceptible to the attack of cerebrovascular diseases on MCA region than male one (54.6% > 42.2%), which means significant differences depending upon sex on statistical basis ($x^2$ = 9.64, p < .01). 6. It was found that male group was more susceptible to the attack of cerebrovascular diseases on ICA region (56.4% > 46.8%), which means significant differences depending upon sex on statistical basis ($x^2$ = 5.71, p < .05). 7. Moreover, it was also found that male group was more susceptible to the attack of cerebrovascular diseases on BA region (2.3% > 0.4%), which means significant differences depending upon sex on statistical basis ($x^2$ = 4.25, p < .05). 8. However, it was found that there was not any significant difference in intracerebral vasculature-specific distributions of cerebrovascular diseases depending on age of subjects, and stenosis comprised larger portion of cerebrovascular diseases than occlusion.

Background: This study focuses on the establishment and operation of a stroke patient hotline program to help patients and their caregivers determine when acute neurological changes require emergency attention. Method: The stroke hotline was established at the Gyeonggi Regional Cerebrovascular Center, Seoul National University Bundang Hospital, in June 2016. Patients diagnosed with stroke during admission or in outpatient clinics were registered and provided with stroke education. Consulting nurses managed hotline calls and made decisions about outpatient schedules or emergency room referrals, consulting physicians when necessary. The study analyzed consultation records from June 2016 to December 2020, assessing consultation volumes and types. Outcomes and hotline satisfaction were also evaluated. Results: Over this period, 6,851 patients were registered, with 1,173 patients (18%) undergoing 3,356 hotline consultations. The average monthly consultation volume increased from 29.2 cases in 2016 to 92.3 cases in 2020. Common consultation types included stroke symptoms (22.3%), blood pressure/glucose inquiries (12.8%), and surgery/procedure questions (12.6%). Unexpected outpatient visits decreased from 103 cases before the hotline to 81 cases after. Among the 2,244 consultations between January 2019 and December 2020, 9.6% were recommended hospital visits, with two cases requiring intra-arterial thrombectomy. Patient satisfaction ratings of 9-10 points increased from 64% in 2019 to 69% in 2020. Conclusion: The stroke hotline program effectively reduced unexpected outpatient visits and achieved high patient satisfaction. Expanding the program could enhance the management of stroke-related neurological symptoms and minimize unnecessary healthcare resource utilization.

Single photon emission computed tomography(SPECT) and positron emission tomography(PET) are modern imaging techniques that allow for both qualitative and quantitative assessment of hemodynamic changes in cerebrovascular diseases. SPECT has been becoming an indispensable method to investigate regional cerebral blood flow because equipment and isotope are easily available in most general hospitals. Acetazolamide stress SPECT has also been proved to be useful to evaluate the cerebrovascular reserve of occlusive cerebrovascular diseases and to select surgical candidate. PET has gained wide spread clinical use in the evaluation of the hemodynamic and metabolic consequences of extracranial or intracranial arterial obstructive disease despite its complexity and limited availability. PET has been established as an invaluable tool in the pathophysilogy investigation of acute ischemic stroke. The potentials, limitations, and clinical applications of SPECT and PET in various cerebrovascular diseases will be discussed in this article with reviews of literatures.
