Clinical observation was made on 52 cases of Stroke that were confined through brain CT, MRI scan. The Stroke cases wee classified into the following kinds cerebral infarction, cerebral hemorrhage, cerebellar or brain stem infarction, cerebellar or brain stem hemorrhage. And among the 52 cases of Stroke cerebral infarction was noticed in 75.00%, cerebral hemorrhage in 11.54%, cerebellar or brain stem infarction in 9.52%, cerebellar or brain stem hemorrhage in 3.85%. The ratio between males and females was 1.74:1 in the whole groups of Stroke and most cases were over 60 of age. As the time of hospitalization, most patients hospitalized from 1 day after stroke to 7 days after stroke. And as the course of hospitalization, most patients hospitalized first. Among the preceding disease at the onset of Stroke hypertention was noted in 32.69%, and deabetes mellitus or heart problem was noted frequently(15.39%). Electrocardiography findings were as follows: The normal was noted in 53.85%, the abnormal in 46.15%. And as the abnormal, left ventricular hypertrophy was noted in 17.54%. The predisposing factors or conditions at the onset of brain infarction were usually initiated during the time of sleeping and those of brain hemorrhage chiefly during the time of exercising like overwork or walking etc. It was noted that smoking a pack of cigarette showed highest disease rate(33.33%) among the average of smoking amount of one day in case of man. Prior to attack, the most chiefly complain was dyspnea or discomfort on chest region. And 30.70% of patients had no previous sign. There were a large number of recurrent cases. The first attack was noted in 71.15%, the 2nd attack in 23.08%, the 3rd attack in 5.77%.

CT 검사 시 뇌출혈의 부위는 심각한 정도에 따라 인지하기 어려운 경우도 있으며, 응급상황에서 숙련이 되지 않은 의료진에게는 부담을 준다. 응급상황에서 검사와 동시에 뇌출혈부위를 자동으로 빨리 파악하고 정량적인 정보를 제공하는 보조적인 역할은 필요하며, 컴퓨터를 이용한 자동 검출 및 인식 시스템은 출혈부위 진단에 매우 큰 도움을 줄 수 있다. 본 연구에서는 출혈부위를 문턱치값 처리, 모폴로지 연산, 원형률 계산을 접목하여 뇌 출혈부위의 자동검출에 성공하였고 검출 후보군에서 잘 못 선정된 영역을 판정하기위한 주성분분석을 이용한 분류기 개발에 성공하였다. 개발된 시스템을 응급상황의 뇌출혈 환자에게 적용한다면 의료진에게 수술계획을 위한 유용한 정보가 될 것으로 사료된다.

Vasoconstriction of intracerebral arteries is the leading cause of delayed cerebral infarction and mortality following aneurysmal subarachnoid hemorrhage. Transcranial Doppler studies show and increase in the flow velocities of basal cerebral arteries, which usually start around day 4 following a subarachnoid hemorrhage, and peaking by days 7 to 14. Angiographic studies confirm the presence of at least some degree of MCA vasospasm when the flow velocities are higher than 100 cm/sec. Mean velocities in the 120 to 200 cm/sec range correspond to 25 to 50% luminal narrowing. MCA and ACA vsospasm is detected with around 90% specificity. Sensitivity is 80% and 50% respectively. A 200cm/sec threshold and rapid flow velocity increase exceeding 50 cm/sec on consecutive days, has been associated with subsequent infarction. Transcranial Doppler is also used to monitor the effects of endovascular treatment of vasospasm. Flow velocities decrease following successful angioplasty or papaverine infusion. Overall, transcranial Doppler studies are considered to have acceptable accuracy for the evaluation of vasospasm in aneurysmal subarachnoid hemorrhage, with limitations that have to be taken into consideration in the clinical setting.

Spontaneous intracerebral hemorrhage (ICH) is a common condition that often leads to death or disability. Accurate prediction of the outcome and decisions regarding the treatment of ICH patients are important issues. We report a case of thalamic hemorrhage with an intraventricular hemorrhage that was suddenly migrated into the third and fourth ventricles in its entirety 8 hours after symptom onset. To our knowledge, this case is the first report of spontaneous migration of thalamic ICH into ventricles, and we suggest a possible mechanism for this case with a brief review of the literature.

The authors report a case of hyperacute, massive hemorrhage in the left basal ganglia with severe midline shift that was treated successfully by the ultrasound-monitored free hand aspiration technique. Every effort was made to shorten time until removal of considerable amount of the hematoma and minimize duration of cerebral herniation, avoiding additional irreversible neurological deficit. A burr hole aspiration technique was preferred to standard craniotomy procedure, and any time-consuming procedures such as stereotactic frame application were abandoned. A burr hole was localized on the basis of computed tomography images simply and quickly with a ruler, and safety of the aspiration procedure was augmented by real-time ultrasound monitoring. Such minimally invasive technique relieved cerebral herniation successfully while avoiding time consumption and the morbidity of major craniotomy procedure. Early resuscitation of the patient with cerebral herniation in this case resulted in excellent recovery of the patient's neurological deficit. The patient's mentality started to improve rapidly and was clear six months after the surgery.

Objective : Removal of blood from subarachnoid space with a lumbar drainage (LD) may decrease development of cerebral vasospasm. We evaluated the effectiveness of a LD for a clinical vasospasm and outcomes after clipping of aneurysmal subarachnoid hemorrhage (SAH). Methods : Between July 2008 and July 2013, 234 patients were included in this study. The LD group consisted of 126 patients, 108 patients in the non LD group. We investigated outcomes as follow : 1) clinical vasospasm, 2) angioplasty, 3) cerebral infarction, 4) Glasgow outcome scale (GOS) score at discharge, 5) GOS score at 6-month follow-up, and 6) mortality. Results : Clinical vasospasm occurred in 19% of the LD group and 42% of the non LD group (p<0.001). Angioplasty was performed in 17% of the LD group and 38% of the non LD group (p=0.001). Cerebral infarctions were detected in 29% and 54% of each group respectively (p<0.001). The proportion of GOS score 5 at 6 month follow-up in the LD group was 69%, and it was 58% in the non LD group (p=0.001). Mortality rate showed 5% and 10% in each group respectively. But, there was no difference in shunt between the two groups. Conclusion : LD after aneurysmal SAH shows marked reduction of clinical vasospasm and need for angioplasty. With this technique we have shown favorable GOS score at 6 month follow-up.

Objective: The aim of this case report was to present the effects of traditional Korean medicine on a patient with Broca's aphasia associated with cerebral hemorrhage after middle cerebral artery infarction. Methods: The Korean version of the Western Aphasia Battery (K-WAB) and the Evaluation of Articulator Performance were used to evaluate the language functions of the patient. Herbal medication and acupuncture were administered to improve the patient's symptoms. Results: The inpatient and outpatient treatments improved the patient's symptoms. The aphasia quotient (AQ) score of the K-WAB test before treatment was 6.4, but it increased to 21.4 after treatment. The Evaluation of Articulator Performance score improved by 0.0 points before treatment, by 1.0 points after 9 days of treatment, and by 1.5 points after 42 days of treatment. Conclusions: This case report suggest that Korean medical therapy can be effective in improving the language functions of patients with Broca's aphasia.

The authors report a unique case of unilateral Moyamoya disease with a rare combination of arteriovenous malformation (AVM) who presented with intracerebral hemorrhage (ICH). A 50-year-old man suffered from sudden onset of mental deterioration and right hemiparesis. Brain computed tomography (CT) showed intracerebral hemorrhage on left thalamus. Brain CT angiography and cerebral digital subtraction angiography (DSA) revealed AVM combined with unilateral moyamoya disease involving left middle cerebral artery (MCA) and choroid plexus in left lateral ventricle. Intraventricular hemorrhage and hydrocephalus were managed conservatively. A rare case of unilateral Moyamoya disease accompanied by a cerebral arteriovenous malformation is described and discussed with review of pertinent literature.

The authors present a rare case of severe vasospasm following the rupture of arteriovenous fistula. On initial CT scan, hematoma in the corpus callosum and left inferior frontal region with surrounding cerebromalacia and all ventricles without apparent subarachnoid hemorrhage were seen. Angiograms showed arterivenous fistula but did not show cerebral vasospasm. Thirteen days after admission the neurological state of patient suddenly deteriorated and bilateral motor weaknesses developed. Following angiograms revealed severe narrowing on the supraclinoid portion of bilateral internal carotid arteries, bilateral anterior cerebral arteries and bilateral middle cerebral arteries. Transluminal angioplasty and intra-arterial papaverine infusion were performed. The patient remained stable with moderate neurologic deficits.
