Dissociative disorder is a psychiatric disorder characterized by a sudden loss of memory, but which has no organic disease or explanation. It usually occurs after heavy psychosocial stress or traumatic experience. A transient cerebral ischemic attack (TIA) is an acute episode of temporary and focal loss of cerebral function of vascular origin. TIAs are rapid in onset; symptoms reach their maximal manifestation in fewer than 5 minutes. Manifestations are of variable duration and typically last 2-15 minutes(rarely as long as 24 h). Most TIA durations are less than 1 hour. Of concern is the careful detection of changes in behavior, speech, gait, memory, movement, and vision. TIAs are uncommon in persons younger than 60 years. I treat 6 cases of Sudden Temporary Amnesia Patients with oriental medicine and they are improved. All of them had amnesia for $6{\sim}10\;hours$. During that time, they show behavioral changes and they are not on the state of unconsciousness. After recovery, they also forget what happen at the time. they have some emotional reason too. In conclusion, 4 cases of them belong to dissociative disorder and 2 other cases, TIA.

Objective : The present study attempts to address the change of management results over time during the past 13 years in good-grade patients with intracranial aneurysm. Methods : Six hundred twenty five [Hunt-Hess grade I to III] out of 826 patients with ruptured intracranial aneurysms operated by the same operator within 3 days after the attack from 1990 to 2002 were selected. Since 1998, endovascular aneurysmal occlusion was done in selected cases of 21 patients. The change of management results over time, including rebleeding rate, delayed ischemic neurologic deficit[DIND] as a cause of morbidity and mortality and surgical outcome were examined. Results : The ratio of poor-grade patients in all patients tended to decrease over the years. The early rebleeding rate declined from 5.0% to 1.2% with the use of tranexamic acid and computed tomography angiogram DIND as a cause of mortality and morbidity has decreased from 12.5% in 1990 to approximately 0% currently. Surgical outcome began to improve significantly in 1994 [poor outcome : 25% in 1990, 12.2% in 1994,6.8% in 2002]. Conclusion : These results suggest that the advances in care and increased experience of the operator significantly affect the change of overall outcome, and early detection of the aneurysm is needed for reducing the ratio of poor-grade patients.

Recently, combination of surgery and radiation therapy (RT) has been recommended in the treatment of craniopharyngioma. RT could be associated with late complications, including vasculopathy. We report two cases of the moyamoya syndrome seen in children with craniopharyngioma who received RT after surgical resection. Thirty-five patients in pediatric age with craniopharyngioma were surgically treated. Fifteen out of 35 patients underwent surgical resection followed by RT or gamma knife surgery. Two of the 15 were found to have symptoms of transient ischemic attack and were diagnosed as moyamoya syndrome through the cerebral angiography. Age at RT was 4 and 13 years, respectively. The latent period for development of the moyamoya syndrome was 27 months and 3 years, respectively, after RT. The RT dose of both patients was 54 Gy. These two patients received bilateral encephaloduroarteriosynangiosis procedures. We report here these two cases of radiation-induced moyamoya syndrome in pediatric craniopharyngioma. Pediatric patients with craniopharyngioma who received RT should be reminded, during follow-up, about the risk of development of the moyamoya syndrome.

Isolated symptomatic occlusion of the anterior cerebral artery (ACA) is a rare condition and until date, only few cases regarding the revascularization of the ACA have been reported. This paper reports on successful attempt to revascularize the ACA using superficial temporal artery (STA) in patient with isolated symptomatic occlusion of the ACA. A 69-year-old man presented with several episodes of transient weakness involving left lower extremity. Cerebral angiography showed occlusion of the right ACA at the A2 segment. After medical treatment failure, the patient underwent STA-ACA bypass surgery. Subsequent to surgery, there was immediate disappearance of transient ischemic attack and follow-up angiography showed favorable revascularization of the ACA territory. Bypass surgery can be considered in the patients with symptomatic occlusion of the ACA, who have experienced failure in medical treatment.

A 71-year-old male with known bronchiectasis and atrial fibrillation was admitted to Seoul St. Mary's Hospital with recurrent transient ischemic attack. R adiofrequency ablation was performed to resolve the patient's atrial fibrillation, but failed. However, a fistula between the left circumflex artery and the bilateral bronchial arteries was found on computed tomography. Fistula ligation and a left-side maze operation were planned due to his recurrent symptom of dizziness, and these procedures were successfully performed. After the operation, the fistula was completely divided and no recurrence of atrial fibrillation took place. A coronary-bronchial artery fistula is a rare anomaly, and can be safely treated by surgical repair.

Statins lower the hyperlipidemia and reduce the incidence of cardiovascular events and related mortality. A 60-year-old man who was diagnosed with a transient ischemic attack was started on acetyl-L-carnitine, cilostazol, and rosuvastatin. After rosuvastatin treatment for 4 weeks, the patient presented with sudden onset fever, cough, and dyspnea. His symptoms were aggravated despite empirical antibiotic treatment. All infectious pathogens were excluded based on results of culture and polymerase chain reaction of the bronchoscopic wash specimens. Chest radiography showed diffuse ground-glass opacities in both lungs, along with several subpleural ground-glass opacity nodules; and a foamy alveolar macrophage appearance was confirmed on bronchoalveolar lavage. We suspected rosuvastatin-induced lung injury, discontinued rosuvastatin and initiated prednisolone 1 mg/kg tapered over 2weeks. After initiating steroid therapy, his symptoms and radiologic findings significantly improved. We suggest that clinicians should be aware of the potential for rosuvastatin-induced lung injury.

Since the introduction of percutaneous; transluminal coronary angioplasty[PTCA] by Grunt-zig in 1977, this is widely used in some patients with coronary artery disease and is an effective alternative to surgery for many patients. Indications for emergency coronary artery bypass graft[CABG] after PTCA are prolonged chest pain, worsening of coronary artery obstruction, "current of injury" by electrocardiogram, cardiogenic shock, and in a lesser incidence, ventricular fibrillation, coronary artery dissection[without obstruction], heart block, and intractable cardiac arrest. Recently, we have experienced one case of emergency CABG following unsuccessful PTCA. The patient was 54 year-old male and admitted with complaint of angina pectoris. The routine electrocardiogram revealed within normal limit. The treadmill test revealed severe chest pain after 2 min. exercise. Coronary cineangiogram revealed 95% segmental stenosis of the proximal right coronary artery. Our cardiologist was planned PTCA. During PTCA, severe chest pain and ischemic pattern on electrocardiogram were developed. But they were not relieved even by morphine and nitroglycerin till 90 min. So we performed emergency single coronary artery bypass graft from aorta to proximal right coronary artery with great saphenous vein. The patient had an excellent postoperative recovery and was free from anginal attack. He has shown striking improvement in general status[NYHA functional class 1] during 6 months after operation.operation.

Aneurysm of extracranial carotid artery which usually originated from trauma, but it can be developed by atheroscrelosis, infection and congenital vascular disease, is defined as abnormal dilatation of intimal wall of carotid artery. The proper management should not be delayed due to occurrence of high neulorogic complication. Recently the authors experienced a case of nontraumatic extracranial internal carotid artery aneurysm, which was successfully resected using intraoperative EEG monitoring for the prevention of ischemic attack and was reconstructed with end to end anastomosis using nylon 9 - 0. On postoperative day #13, we could confirm well healed aneurysmal site and normal blood flow in the view of arteriography.

Post-stroke atrial fibrillation has been frequently reported especially in the patients with right insular infarct as an evidence of cerebrogenic mechanism affecting on cardiac rhythm. However, conversion to normal sinus rhythm after stroke in patients who had atrial fibrillation has not been reported. A 88-year-old men who had untreated atrial fibrillation was admitted to hospital due to left middle cerebral artery territory infarction. During admission, second ischemic attack occurred in right middle cerebral artery territory. At that time, his atrial fibrillation converted spontaneously to normal sinus rhythm. Restored sinus rhythm sustained until he died due to sepsis. This case is evidence supporting a theory that brain is associated with control of cardiac rhythm. If no risk factor is revealed by intensive investigation in patients with acute cerebral infarctions that cardioembolism is strongly suspected as a cause, physicians should concern transformation of atrial fibrillation to normal sinus rhythm after stroke.
