Resuscitative endovascular balloon occlusion of the aorta (REBOA) is widely performed as an adjunct to resuscitation or bridge to definitive control of non-compressible torso hemorrhage in patients with hemorrhagic shock. It is a crucial adjunct for the maintenance of cerebral and coronary perfusion during resuscitation. However, in polytrauma patients with concomitant neurotrauma, such as traumatic brain injury (TBI) or spinal cord injury, the physiological effects of REBOA are unclear. In this report on REBOA performed in a clinical setting for polytrauma patients with spinal cord injury or TBI, the physiological effects of REBOA in neurotrauma are reviewed.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been increasingly used in recent years as a resuscitative adjunct for trauma patients with life-threatening non-compressible torso hemorrhage. By blocking the aorta temporarily with an inflated balloon, REBOA preserves cerebral and coronary perfusion while diminishing exsanguination below the balloon, thereby providing time for resuscitation and definitive bleeding control. When determining the occlusion zone during the REBOA procedure, factors such tortuosity of the aorta, co-occurring minor chest injuries, and the severity of shock must be considered, as well as the main injury site. This paper describes a case of high Zone I REBOA in an elderly patient with a tortuous aorta who had concomitant injuries of the chest and pelvis.

The intra-arterial administration of nimodipine (IAN) is commonly used for cerebral vasospasm refractory to medical treatments. We report two cases of vasogenic edema after IAN. Our patients with aneurismal subarachnoid hemorrhage presented with vasospasm, which was treated by IAN. Consequently, vasogenic edema developed in the basal ganglia. Reperfusion following IAN for vasospasm may have the potential for inciting vasogenic edema in the ischemic brain.

King Gojong was the twenty-sixth King in the Choseon Dynasty. He took the throne when he was only 12 years old and had to set up regency for 10 years. During his period, situations were worsened in both domestic and foreign affairs. In the end, after 3 years from abdication of the throne, the Choseon Dynasty was overthrown in compliance with a coercion by Japanese empire. He died in 68 years old. We can assume that his inveterate disease are weakness of the spleen and the stomach. In addition, he suffered from a boil, a cold, dermatosis, eye disease, an external wound, dentistry disease, arthritis, etc. The official cause of his death was cerebral hemorrhage. But we assume that the possibility of poison murdering is high.

To exhibit our clinical experience of diffusion-weighted (DW) MR imaging for various brain pathologies and to determine its role in characterizing brain pathologies in children. DW images in 177 children (M：F＝96：81, mean age, 4.7 years) with various brain pathologies were retrospectively collected over past 3 years. DW images (b value： 1000 s/mm) were reviewed along with corresponding apparent diffusion coefficient (ADC) maps. Brain pathologies included cystic or solid brain tumor (n = 55), cerebral infarct (n = 32), cerebritis with or without brain abscess (n = 21), metabolic or toxic brain disorder (n = 19), demyelinating disease (n = 16), hypoxic-ischemic encephalopathy (n = 16), intracerebral hemorrhage including traumatic brain lesion (n = 15), and posterior reversible leukoencephalopathy (n = 3). We reviewed whether DW images and ADCmaps contribute to further characterization of brain pathologies by defining a chronological age of lesions, the presence of cytotoxic edema in lesions, and the nature of cystic lesions.

Objective: This study was conducted to know the survival probability of the patients with cerebrovascular disease. Method: 1,341 patients who were suspected of having cerebrovascular disease clinically were investigated by telephone and NHIC (National Health Insurance Corporation) data. Conclusion: 1. The study population was grouped as 'Negative Brain CT findings' (11.8%), 'Hemorrhage' (12.4%) and 'Infarction' (75.7%). 2. The survival probabilities calculated by the Life Table method were statistically significant among brain CT finding groups (P<0.01). 3. The mean survival time calculated by the Kaplan-Meier method were also statistically significant among brain CT finding groups (P<0.01). 4. The result of Cox regression model was that sex (OR=0.7), age (OR=1.07), diabetes mellitus (OR=1.38), and heart disease (OR=1.69) affected the survival of the patients with cerebrovascular disease.

From October, 1986, to June, 1992 16 patients, 13 male and 3 female patients ranging in age 28 to 70 years, were operated on for thoracic aortic aneurysm, The etiology of these patients was atherosclerotic in 10, cystic medial necrosis in 4, and trauma in 2 cases, All patients were treated by use of CPB and circulatory arrest was applicated in one patient, Ten patients had aneurysms involving ascending aorta and six patients had descending aortic aneurysm, Among ten patients with ascending aortic aneurysm, annuloaortic ectasia with aortic regurgitation were seven and all underwent surgery with composite technique [Bentall operation], The other six patients with descending thoracic aneurysm were performed graft replacement. There was no early mortality but two late deaths occurred due to cerebral hemorrhage and renal problems at POD 3mo and 39mo respectively, We obtained satisfactory long-term results and overall survival rate at 5 year was 74.7%.

Valve replacement in children and adolescents, aging below 20 years [Mean 15 years 4 months], has been done at Seoul National University Hospital from March 1977 to September 1982 . Seventy-Seven patients have received 91 artificial valves 4 prosthetic valves and 87 bioprosthetic valves. 63 patients had acquired valve lesions and 14 patients had congenital valve lesions. Among the patients with acquired valve lesion, 32 patients had the history of rheumatic fever. Seventy-five patients survived operation: 12 patients [ 15.6%] died within one month postoperatively and 3 patients [3.9%] during the follow-up period with the overall mortality rate of 19.5% Thromboembolic complication occurred in 3 patients with 2 deaths: 3.9% embolic rate or 3.74% emboli per patient-year. One patient who had been on coumadin anticoagulation died from cerebral hemorrhage. Actuarial survival rate was 77.6% at 1 years after surgery, after then there were no death.

This survey was performed to report rare outbreak of liver cirrhosis in Korean native goat (KNG) which was died of Yangpyeong's goat farm on Feb. 1992. The examination for the KNG was carried out by clinical signs, necropsy and various lab-oratory test including parasitic, bacterial and histological test. The KNG looked jaundice, ascite, hemorrhage of lumen, abomasum and intestine, and brownish smooth cirrhotic liver at necropsy. Histological examination for liver revealed considerable proliferation of connective tissue and piecemeal necrosis which was caused by chronic active inflammation in interlobules and intralobules. There were atrophic micro and macro nodules which were sur-rounded by connective tissue. The lobular structure lack almost all central vein. The portal areas appearred proliferation of bile ducts, blood vessels and connective tissues. These connective tissue infiltrated heavily with plasma cells, Iymphocytes and histocytes. Histological examination for brain proved to be hepatic encephalopathy by virture of congestion and edema in cerebral medullary. From these results were demonstrated miked nodular, active, postnecrotic liver cirrhosis.

We report a 18-year-old man, who has been taking antihypertensive medication for 1month in a local clinic, presented with a sudden onset headache followed by left blindness. He experienced palpitation and chest discomfort during physical exertion since 2years before admission, but unfortunately has been ignored. Brain CT showed intracerebral hemorrhage in the left temporoparietal area, but cerebral angiogram and magnetic resonance image revealed no vascular anomaly. He was managed conservatively, and headache and visual loss were improved over time. Subsequently, on the evaluation of hypertension, he was diagnosed as having extra-adrenal pheochromocytoma on left paraaortic area from the results of endocrinological evaluations, abdominal CT scan, and $^{131}I$-MIBG scintigraphy.
