Background and Purpose : Cerebrovascular reactivity(CVR) can be estimated by measuring the change of cerebral blood flow that occurs during vasostimulation. To estimate the cerebrovascular reactivity, we investigated the change of flow velocity of the middle cerebral artery(MCA) during hyperventilation and hypoventilation with the transcranial doppler. So we studied whether the CVR measured by this method could show a significant difference between the normal and the cerebral infarction subjects and whether the CVR may decrease with age in normal subjects. Methods : Using transcranial doppler, we measured the mean velocity(Vm), the pulsatility index(P.I.) at the resting state, the end of breath-holding and the end of hyperventilation in 36 normal and 10 cerebral infarction subjects, so we calculated the percentile change of mean velocity(%${\Delta}$Vm) and P.I.(%${\Delta}$P.I.) after the vasostimulation. We estimated the change of Vm, P.I., %${\Delta}$Vm and %${\Delta}$P.I. by the age group and compared those parameters between the age-matched normal control and cerebral infarction subjects. Results : The Vm in MCA significantly decreased with age(p<0.05), but there was no significant difference in Vm and P.I. between normal and cerebral infarction subjects. The %${\Delta}$Vm and %${\Delta}$P.I. in response to hyperventilation significantly decreased with age in MCA and there was significant difference in $%{\Delta}Vm$ of MCA after breath-holding between the normal and cerebral infarction subjects. Conclusion : The breath-holding and hyperventilation tests could be non-invasive and useful methods in estimation of the cerebrovascular reactivity and could be applied in the basal and follow-up evaluation of the cerebrovascular reserve of the ischemic stroke patients.

This study was done to investigate the blood pressure, BMI and serum lipids of cerebrovascular accident patients in Seoul. The subjects were 195 Korean urban cerebrovascular accident patients who were hospitalized at Dong Seo Oriental Hospital in Seoul from June, 1997 to December, 1997. There were more cerebral infarction patients(164) than cerebral hemorrhage patients(31). Cerebral infraction patients were prevalent for subjects in their sixties, but cerebral hemorrhage patients were most commonly in their fifties. The BMI of cerebral infarction accidents was significantly higher than that of cerebral hemorrhage patients(p<0.05). Mean diastolic blood pressure of cerebral hemorrhage patients was significantly higher than that of the cerebral infarction patients(p<0.05). The mean systolic blood pressure of the cerebral hemorrhage patients was higher than that of the cerebral infarction patients, not statistically significant. The serum total cholesterol and glucose levels of the cerebral infarction patients was significantly higher than those of the cerebral hemorrhage patients(p<0.05). Serum total cholesterol(p<0.01), triglyceride(p<0.05) and LDH(p<0.01) levels of female subjects were significantly higher than those of male subjects. Serum total cholesterol has a negative correlation with serum GOT and GPT, but has a positive correlation with triglyceride. Serum triglyceride has a negative correlation with diastolic blood pressure but has a positive compellation with serum glucose.

Background and Purpose: The greater part of patients to visit Hospital of Oriental Medicine suffer from cerebrovascular accident(CVA). There is transcranial Doppler(TCD) in the diagnostic method to confirm cerebrovascular accident(CVA). Transcranial Doppler(TCD) is an accurate method of monitoring the blood flow velocities of the cerebral vessels and have been generally used to prevent symptomatic vasospasm and confirm cerebral infarction. So we studied, in the crebrovascular accident(CVA), to estimate whether transcranial Doppler(TCD) is useful to. Methods: Using transcranial doppler(Multigon Model 500M Transcranial Doppler System), we measured the mean and peak velocity and the direction of blood flow in 10 cerebrovascular accident(CVA)'s subjects who had been examined by Computed Tomography(CT) or Magnetic Resonance Imaging (MRI). Results : As an anticipation, in cerebrovascular accident(CVA)'s subject with Cb-infarction, the mean and peak velocity of blood flow fell down remarkably and the direction of blood flow was change or irritable. But didn't find out any signal in lacunar infarction. Also, in case with spontaneous hemorrhage, the velocity and direction of blood flow was change but this signal was short of diagnosis for Cb-hemorrhage. Besides, we found signals about embolism, stenosis, thrombosis and occlusion in cerebrovascular accident(CVA)'s subjects. Conclusion: In Cb-infarction, the result of TCD was equal to diagnosis with Computed Tomography(CT) or Magnetic Resonance Imaging (MRI). But about lacunar infarction or spontaneous hemorrhage, signals of TCD couldn't be found out or was insufficient more than Computed Tomography(CT) or Magnetic Resonance Imaging(MRI). In cerebrovascular accident(CVA)'s subject with embolism, stenosis, thrombosis or occlusion, signals of TCD were found out more than Computed Tomography(CT) or Magnetic Resonance Imaging(MRI). Therefore transcranial doppler(TCD) is necessary method which makes a diagnosis of cerebrovascular accident(CVA), with Computed Tomography(CT) or Magnetic Resonance Imaging(MRI).

The purpose of this study was to examine how lacunar infarction developed and what its characteristics were. As this disease had little noticeable clinical symptoms and is likely to draw less attention than other types of cerebrovascular diseases like panhemispheric infarction, it‘s difficult to make an early diagnosis of it or treat it successfully. The subjects in this study were 196 people who showed no clinical symptoms and took a MRI test. When the MRI test data were analyzed, signal intensity and the part where that disease was detected were primarily taken into account. As a result, it's found that 116 people had no lacunar infarction and 80 people suffered from that disease, including 13 with very mild lacunar infarction, 41 with mild lacunar infarction and 26 with lacunar infarction. However, very mild and mild lacunar infarction could not be viewed as clinically significant cases, and only 26 people, which accounted for 13 percent of the subjects, should be considered to be diagnosed with lacuanr infarction. The most common part where that disease was found was white matter and basal ganglia, regardless of gender. Accordingly, those who are exposed to health hazards such as hypertension or diabetes should take a MRI test to prevent cerebrovascular diseases that might be caused by those illnesses.

Purpose To explore cerebrovascular reservoir (CVR) and arterial transit time (ATT) changes using acetazolamide-challenged multi-phase arterial spin labeling (MP-ASL) perfusion-weighted MRI in chronic cerebrovascular steno-occlusive disease. Materials and Methods This retrospective study enrolled patients with chronic steno-occlusion who underwent acetazolamide-challenged MP-ASL between June 2019 and October 2020. Cerebral blood flow, CVR, basal ATT, and ATT changes associated with severe stenosis, total occlusion, and chronic infarction lesions were compared. Results There were 32 patients (5 with bilateral steno-occlusion) in our study sample. The CVR was significantly reduced during total occlusion compared with severe stenosis (26.2% ± 28.8% vs. 41.4% ± 34.1%, respectively, p = 0.004). The ATT changes were not significantly different (p = 0.717). The CVR was marginally lower in patients with chronic infarction (29.6% ± 39.1% vs. 38.9% ± 28.7%, respectively, p = 0.076). However, the ATT was less shortened in patients with chronic infarction (-54 ± 135 vs. -117 ± 128 ms, respectively, p = 0.013). Conclusion Acetazolamide-challenged MP-ASL provides an MRI-based CVR evaluation tool for chronic steno-occlusive disease.

The loss of consciousness in the dental office have many causes, such as, vasodepressor syncope, drug administration, orthostatic hypotension, epilepsy, hypoglycemic reaction, acute adrenal insufficiency, acute allergic reaction, acute myocardial infarction, cerebrovascular accident, hyperglycemic reaction and hyperventilation. Patients have fainted during all phases of dental care: during tooth extraction and other surgical procedures, during local anesthetic injections, or during procedures such as venipuncture, on being seated in the dental chair, and even on first entering the dental office. If an elderly patient with known cardiovascular or cerebrovascular problems experiences a syncopal episode, differentiation from cerebrovascular insufficiency of more serious etiology, such as cerebrovascular accident, must be considered. And anaphylactic shock is also suggested during intravenous drug administration. This is a case report of syncope care during venous injection of cephalosporin in patient with cerebrovascular accident.
