  • Blunt cerebrovascular injury is defined as a vertebral or carotid arterial structural wall injury resulting from nonpenetrating trauma. Complete traumatic internal carotid artery occlusion is very rare condition accounting for 0.08~0.4 0f all trauma patients and believed to be associated with the greatest risk of ischemic stroke reported in 50~90% in a few small series. A 55-year-male was admitted with drowsy mentality and severe headache after a fall down accident. Brain computed tomography showed a subdural hematoma at the both frontal area with a fracture of the occipital skull bone. Two days after admission, he suddenly complained with a right side hemiparesis of motor grade 2. Brain magnetic resonance diffusion demonstrated multiple high flow signal changes from the left frontal and parietal lesion. Computed tomographic angiogram (CTA) revealed absence of the left ICA flow. Trans femoral cerebral angiography (TFCA) showed complete occlusion of the left internal carotid artery (ICA) at ophthalmic segment in the left ICA angiogram and flows on the left whole hemispheric lesions through the anterior communicating artery in the right ICA angiogram. We decided to conduct close observations as a treatment for the patient because of acute subdural hematoma and sufficient contralateral cerebral flow by perfusion SPECT scan. Two weeks after the accident, he was treated with heparin anticoagulation within INR 2~4 ranges. He recovered as the motor grade 4 without another neurologic deficit after 3 months.

  • Objectives : The purpose is to discuss the clinical applications of Orungsan(Goreisan: 五苓散) as an alternative management for increased intracranial pressure in the field of neurosurgery in Japan. Methods and Results : Attention has focused on Kampo medicine(traditional Japanese medicine) for some cerebral disease including chronic subdural hematoma(CSDH) and cerebral infarction in Japan. Orungsan and one of its classes, Sirungtang(Saireto: 柴苓湯) are well known their effects on brain edema. After some studies of Orungsan has the anti-edemic effects by the inhibition of aquaporin, this herbal medicine has been used widely in the neurosurgery field in Japan. It is high time to think about where we are and we go ahead for the progress and the integration in medicine. We have reviewed the studies using Orungsan or Sirungtang, that was reported at the 20th annual meeting of 'the Japan society for Kampo medicine and neurological surgery' was held on November 5, 2011 in Tokyo. Fifteen studies related with Orungsan or Sirungtang were reported among all 32 studies at the meeting. Orungsan in ten, and Sirungtang in five among 14 studies contained specific clinical case. In the aspects of disease, thirteen papers were related with SDH, including CSDH(11), SSDH(1), aneurism clipping for SDH prevention(1), and one was acute cerebral infarction and one was multiple metastatic brain tumor. In the report style, case control study was 7(mostly retrospective), and the case report was 8. Conclusions : Orungsan may be plausible to be an alternative method to reduce brain edema after SDH and other brain injury in the field of neurosurgery.

  • 본 연구는 일과성허혈발작 및 급성뇌경색환자에서 양쪽 중 간대뇌동맥의 혈류속도 차이가 예후를 예측할 수 있는 지표가 될 수 있고, 이러한 예후예측력이 뇌졸중 아형 간에 차이가 있는 지를 관찰하는 것이다. 모든 대상자는 일과성허혈발작 및 급성뇌경색환자들이며, 기본적인 평가와 경두개도플러검사(TCD)가 실시되었다. 중간대뇌동맥 비대칭 지수(MCA asymmetry index)는 다음의 공식에 의해 구해졌다; MCA asymmetry index=(|RMCA MFV-LMCA MFV|/mean MCA MFV) ${\times}100$. 뇌경색 분류는 TOAST classification에 따라 진행되었다. 나쁜 예후(poor functional outcome)는 mRS score ${\geq}3$ at 3 months after stroke onset로 정의하였다. 총 988명의 급성뇌경색환자가 분석에 포함되었고, 그 중 157명(15.9%)이 나쁜 예후를 가지고 있었다. 뇌경색 하위유형 및 여러 혼란변수를 보정 후 실시한 다변량분석에서 중간대뇌동맥 비대칭 지수만 유일하게 독립적으로 나쁜 예후와 연관성을 보였다. ROC curve 분석에서 중간대뇌동맥 비대칭 지수를 예측모형에 투입하였을 때 투입 전에 비해 나쁜 예후를 예측하는 능력이 상승하는 것을 관찰하였다(from 88.6% [95% CI, 85.2-91.9] to 89.2% [95% CI, 85.9-92.5]). 급성뇌경색환자에서 중대뇌동맥 비대칭 지수는 나쁜 예후를 독립적으로 예측하였다. 따라서 경두개도플러검사는 급성뇌경색환자에서 나쁜 예후를 예측하는데 유용하게 사용될 수 있을 것이다.

  • Objective : Endovascular treatment (EVT) outcomes for acute M2 segment of middle cerebral artery occlusion remains unclear because most results are obtained from patients with large artery occlusion in the anterior circulation. The objective of this study was to assess procedural outcomes for acute M2 occlusion and compare outcomes according to thrombus location (M1 vs. M2). Methods : A systematic review was performed for online literature published from January 2004 to December 2016. Primary outcome was successful recanalization rate and symptomatic intracranial hemorrhage (S-ICH) after the procedure. A fixed effect model was used if heterogeneity was less than 50%. Results : Eight articles were included. EVT showed successful recanalization rate of 69.1% (95% confidence interval [CI], 54.9-80.4%) and S-ICH rate of 6.1% (95% CI, 4.5-8.3%). The rates of good clinical outcome at 3 months and mortality were 59.4% (95% CI, 49.9-68.2%) and 14.9% (95% CI, 11.4-19.3%), respectively. According to thrombus location (M1 vs. M2), successful recanalization (odds ratio [OR], 1.539; 95% CI, 0.293-8.092; p=0.610) and S-ICH (OR, 1.313; 95% CI, 0.603-2.861; p=0.493) did not differ significantly. Good clinical outcome was more evident in M2 occlusion after EVT than that in M1 occlusion (OR, 1.639; 95% CI, 1.135-2.368; p=0.008). However, mortality did not differ significantly according to thrombus location (OR, 0.788; 95% CI, 0.486-1.276; p=0.332). Conclusion : EVT seems to be technically feasible for acute M2 occlusion. Direct comparative studies between EVT and medical treatment are needed further to find specific beneficiary group after EVT in patient with M2 occlusion.

  • Objectives: We were to assess the effectiveness of combined therapy of Oriental Medicine and Western Medicine on acute stroke. Methods: We selected acute middle cerebral artery territory infarction subjects, within 3 days after stroke onset, who had never have any type of stroke history before. The subjects, admitted to department of Oriental Medicine, received combination therapy of western medical treatment including thrombolytic, anticoagulant, or antiplatelet agents and oriental medical treatment including acupuncture and herbs medication. The other subjects, admitted to department of Neurology, received only modern western medical treatment. The National Institute of Health Stroke Scale (NIHSS) was checked at admission, 1 week and 2 weeks later to assess neurologic improvement. The Modified Barthel Index (MBI) was checked 1 week and 2 weeks after admission to motor function recovery. Results: Comparing the NIHSS between baseline and 1 week later, the combination therapy group showed more improvement than the single-treated with anticoagulants group. However, there was no significant difference between the two groups, comparing 1 week and 2 weeks later with the NIHSS and the MBI. Conclusions: Combination therapy have more beneficial effect on acute stage of stroke.

  • Fat embolism syndrome is a rare but alarming, life-threatening clinical condition attributed to fat emboli entering the circulation. It usually occurs as a complication of long-bone fractures and joint reconstruction surgery. Neurological manifestations usually occur 12 to 72 hours after the initial insult. These neurological complications include cerebral infarction, spinal cord ischemia, hemorrhagic stroke, seizures, and coma. Other features include an acute confusional state, autonomic dysfunction, and retinal ischemia. In this case series, we describe three patients with fat embolism syndrome who presented with atypical symptoms and signs and with unusual neuroimaging findings. Cerebral fat embolism may occur without any respiratory or dermatological signs. In these cases, diagnosis was established after excluding other differential diagnoses. Neuroimaging using brain magnetic resonance imaging is of paramount importance in establishing a diagnosis. Aggressive hemodynamic and respiratory support from the beginning and consideration of orthopedic surgical intervention within the first 24 hours after trauma are critical to decreased morbidity and mortality.

  • Objectives : Coptidis Rhizoma (Coptis japonica MAKINO; CR) is a well known crude drug as antimicrobial, antibacterial, anti-inflammatory, antioxidant activity. However, there is no study of the effect of CR on brain infarction and it's mechanism. The aim of this study was to investigate the effects on ischemic stroke induced by photothrombotic infarction by evaluating the functional & neuronal recovery after brain infarction. Materials & Methods : Male Sprague-Dawley rats (250-300 g) were induced photothrombotic brain infarction on sensorimotor cortex, and brain infarction volume by image J software (NIH, USA) after Nissl stain, also single pellet reaching task as a functional motor recovery were observed. After orally pretreated by CR (500 mg/kg) or normal saline as a sham control before 7 days from the time of photothrombotic infarction, rats were sacrificed. After then we analysed anti-inflammatory cytokines (TNF-$\alpha$, IL-6, IL-1$\beta$), by RT-PCR and ELISA method, and immunohistochemistry (GFAP, connexin-43) as a marker of neural plasticity. Results : CR (100, 250, 500 mg/kg) decreased the infarction volume dose-dependently, however the effect of 500mg/kg of CR (CR 500) showed the best (P=0.051). Also, CR 500 decreased the infarction volume time-dependently, the most effective time was 3-7 days after stroke. Photothrombosis increased inflammatory cytokines after infarction, CR 500 suppressed significantly mRNA expression of IL-1$\beta$, IL-6 and TNF-$\alpha$. In serum, CR 500 decreased the amount of IL-1$\beta$, 12h, 24h and 48h respectively (p < 0.05), also decreased that of IL-6 and TNF-$\alpha$, 12h respectively (p < 0.05) after infarction. The more astrocytes were observed and neural plasticity was facilitated in the rat brain of CR 500 than that of sham control in immunohistochemistry. Conclusions : This results suggest that CR decrease infarction volume and improve functional motor recovery in acute stage in photothrombotic ischemic infarction model in the mechanism of anti-inflammation and promoting neural plasticity.

  • Blood circulation of brain is divided into two major categories; anterior one from carotid artery and posterior one from vertebrobasilar artery. In stroke patients, it is important to diagnose which is involved, because there is many difference in the aspects of clinical menifestations and prognosis, especially in the acute stage. In some cases of vertebrobasilar infarction, such as Wallenberg's syndrome, charicteristic cranial nerve signs, eye movement disorders and cerebellar signs are appeared. And in Dejerine's syndrome, only pure motor or sensory defecits can be appeared without any brainstem signs. So It shoud be differenciated by Brain MRI from those of the cerebral hemisphere lesions. And in the cases that nausea, vomitting and dysphagia are the first menifestations, it is frequently misdiagnosed as internal medical disease, causing appropriate treatment delayed. In this case report, we are to describe the clinical menifestations and progresses of two cases of brainstem infarctions, review previously published case reports about them and compare them to our cases. The first is Dejerine's syndrome i.e. medial medullary infarction, the second is Wallenberg's syndrome i.e. lateral medullary infarction. Simultaneously we are to investigate the oriental medical approach in the bran stem infarctions.
