Intracardiac hemangiomas are very rare primary cardiac tumor and there have been at least 37 reports of surgically resected cardiac hemangiomas. Most cardiac hemangiomas are asymptomatic. In symptomatic patients, symptoms are related to the location of tumor and outflow tract obstruction or obstruction of inferior and/or superior vena cava. Sudden death may occur due to conduction disturbances. The principle of treatment is surgical resection, and the prognosis is dependent upon the size, location and multiplicity of the tumor. A 40 year old man was admitted due to chest contusion and was found to have an intracardiac mass during echocardiographic examination. The mass was successfully removed and pathologic examination showed benign hemangioma. The patient was recovered uneventfully in postoperative period and was followed up for 1 year without evidence of recurrence.

Acute mesenteric ischemia after cardiac surgery is a serious complication associated with high mortality. Superior mesenteric artery is most commonly affected artery. Acute obstruction of mesenteric artery generally has an unfavorable prognosis because of late diagnosis. The keys to a successful outcome are early diagnosis and appropriate operative intervention. We successfully treated a patient with acute mesenteric ischemia after aortic valve replacement. Therefore, we report a case with a review of articles.

Aortic aneurysm has poor prognosis and high mortality, but the incidence of aortic aneurysm is in increasing state. From July, 1986 to July, 1996, we operated on 25 patients with aortic aneurysm and analysed the clinical results and relations between the duration from symptoms onset to operation(Sx-Op), the duration from admission to operation(Adm-Op), preoperative blood pressure, preoperative heart rate and postoperative mortality, retrospectively. The patients were classified as dissecting aneurysm(10 cases), abdominal aortic aneurysm(9 cases), Marfan's syndrome(3 cases), descending thoracic aortic aneurysm(3 cases). The operative technique were graft interposition in 17 cases, Bentall's operation in 4 cases, aneurysm bypass in 2 cases, and wrapping of aorta in 2 cases. Seven patients died of several causes, bleeding in 5 cases, acute renal failure in 1 case and respiratory failure in another one case. Before 1992, the early stage of operation, 6 mortality among 14 operated patients occurred, and after then 1 mortality among 11 operated patients occurred. Eighteen survivors were followed up from 1 to 118 months(mean 50.6 months), and total follow up was 911 patient-months. During the follow up period one patient died of melena 30 months after operation. The other patients did not complain chest pain or dyspnea. The surgical mortality was improved in the late period, and the major cause of death was intraoperative or postoperative bleeding. The Sx-Op duration, the Adm-Op duration, preoperative blood pressure and preoperative heart rate were proven to have no statistical relations with postoperative mortality.

This study was conducted to analyze the results of inhalation anesthesia performed at the equine hospital of Korea Racing Authority (KRA) and to find out the influencing factors on mortality during and/or after inhalation anesthesia. Among 585 cases of anesthesia, orthopedic surgery (410) was performed the most frequently, followed by colic surgery (85) and upper airway surgery (45). Twenty out of 585 horses were either euthanized or died during and/or after anesthesia. Among those twenty horses, fourteen horses received colic surgery, three received orthopedic surgery, and three others received upper airway surgery. The major causes of mortality were rupture of intestine in colic surgery and airway obstruction during recovery in upper airway surgery. Myopathy, refracture, laminitis were the causes of mortality in orthopedic surgery. Consequently, the horses that received colic and upper airway surgeries showed significantly high mortality rate rather than horses that received orthopedic surgery (p < 0.01). According to the results, horses that received colic surgery showed the highest mortality rate from euthanasia due to poor and grave prognosis. To reduce the perioperative mortality of horses, it is recommended to perform perioperative intensive care for colic surgery and careful monitoring for upper airway surgery during recovery.

Purpose: We wanted to assess the radiological and clinical results and the prognostic factors after an operation for capitellar fractures associated with/without other injury around the elbow. Materials and Methods: Among the 25 patients (mean age: 49 years-old) who underwent open reduction and internal fixation for capitellar fractures, there were nineteen type 1 fractures and six type 3 fractures. The mean follow up period was 14.8 months. We assessed the factors affecting the radiological and functional results, such as the fracture pattern, the patient age and the surgical approaches. Results: In 24 of 25 patients, bony union was achieved at postoperative 1 year. There were eighteen excellent, four good, two fair and one poor functional results according to the Broberg and Morrey elbow score. The most common type was type 1 and the most common associated injury was lateral condylar fracture. The patients with type 1 fracture rather than the patients with type 3 fracture and the patients who had an extraarticular associated fracture rather than an intraarticular associated fracture had better clinical outcomes. Conclusion: 22 (88%) of the patients were satisfied at the result. The type of capitellar fracture and an associated intraarticular elbow fracture were shown to be important prognostic factors in this study.

A 16-year-old female Shih-Tzu, weighing 5 kg, presented with clinical symptoms of abdominal distension and urinary and fecal incontinence. Abdominal palpation detected a large mass. According to the radiographic findings, the bladder had been moved to the umbilicus by the mass and a large abdominal mass was confirmed in the lower abdominal area. Ultrasonography indentified a large heterogeneous mass with heterogeneous parenchyma and a focal anechoic area in the lower abdominal area. The complete blood count abnormalities suggested thrombocytosis and mild neutrophilia, and the serum chemistry indicated an elevated alkaline phosphatase value. During laparotomy, a firm mass that measured $10.5{\times}9.6cm$ was found between the uterine cervix and urinary bladder. The urethra was embedded in the mass. A diagnosis of leiomyosarcoma was established based on histopathology and histochemistry. One week after surgery, urinary retention symptoms that did not appear to be related to mechanical obstruction presented suddenly, but they did not respond to several drug treatments, thus long-term conservative therapy was adopted. The urinary symptoms disappeared on day 27 and the patient started to void large quantities of urine in a smooth and frequent manner. This case report describes the serial changes in the patient's status and the response after surgical remove of the urethra embedding leiomyosarcoma.

Purpose : Neuroblastoma is a malignant neoplasm which arises from primitive sympathetic neuroblasts, and occasionally can matured from a malignant neuroblastoma into a benign ganglioneuroma. It has the highest rate of spontaneous regression of any pediatric tumor. We performed a retrospective study of pathologic features after combination therapy in advanced neuroblastoma. Prognostic effects of the individual morphologic feature and prognostic groupings according to modified Shimada classification systems were analyzed. Methods : The treatment results for six patients with neuroblastoma seen at Keimyung University from Jan. 1991 to June 2000 were analyzed. Patients were treated with a combination of chemotherapy, radiation therapy, and surgery, and classified by two major prognostic criteria based on morphological features of neuroblastoma, such as modified Shimada classification and histologic grading. Results : Three cases were classified to a good histologic group; among them, two cases survived, but one case was lost in follow-up. There were three cases classified in a poor histologic group. All of these patients expired due to sepsis and hemorrhagic pancreatitis. Conclusion : Prognostic classification due to pathologic findings had significant value in evaluating the survival rate of neuroblastoma patients.

Purpose: Gastric cancer is the most common malignant tumor in Korea. We reviewed the cases at our institution to identify the survival rates and clarify the prognostic factors of patients with gastric cancer. Materials and Methods: We conducted a retrospective study of 6,918 patients who had received a diagnosis of gastric cancer, and they underwent surgery at Korea Cancer Center Hospital during a 15-year period from 1991 to 2005. Results: The overall 5-year survival rate was 66.8%. The univariate analysis revealed that age, location of tumor, gross type of tumor, the histology according to the WHO classification, the Lauren classification, depth of invasion (T stage), lymph node metastasis (N stage), distant metastasis (M stage), the type of surgery, the UICC TNM stage, postoperative complications, adjuvant chemotherapy, lymphatic invasion, venous invasion and perineural invasion were the significantly different factors of the survival rates. The multivariate analysis revealed that age, Borrmann type 4, the histology according to the WHO classification, depth of invasion (T stage), lymph node metastasis (N stage), distant metastasis (M stage), the type of surgery, UICC TNM stage, postoperative complications, adjuvant chemotherapy and lymphatic invasion were the independent prognostic factors. Conclusion: We have shown a statistically significant association between the survival rates after operation for gastric cancer and the clinicopathologic factors. Early diagnosis of gastric cancer, appropriate surgeryand adjuvant therapy might improve the quality of life and the survival rates of gastric cancer patients.

Background: To evaluate the efficiency of surgical treatment in patients with cardiac valvular and arterial involvement of Behcet's syndrome. Material and Method: 12 patients underwent surgical treatment due to the valvular heart diseases and the various arterial diseases associated with Behest's syndrome over 7 years; 6 with valvular heart disease, 1 with annuloaortic ectasia, 1 with ascending aortic aneurysm, 4 with pseudoaneurysms in abdominal aorta(n=2), carotid artery(n=1), and popliteal artery(n=1). All 12 patients had received valvular replacement(n=6) and the artificial(n=5) or autologous(n=1) graft interposition. We followed the results of these surgical treatments. Result: Operations were technically successful in all 12 patients and peri-operative complication was not demonstrated. However, 10 patients had recurrences; 6 with valvular dehiscence, 3 with pseudoaneurysm at anastostomosis site, and 1 with aorto-duodenal fistula. The duration of recurrence was 1 to 55 months(mean: 15.7$\pm$ 16.2 months). 7 patients underwent the second operation and among them, 4 patients showed repeated recurrences. Overall, 5 patients died 2 to 25 months after the operation(mean: 13.6 months), because of the bleeding at the anastomosis site Five patients did not present recurrence after the first(n=2) or the second operation(n=3) and their follow up duration was 5 to 60 months(mean: 45.8$\pm$41.7 months). Five patients received immune-suppressive therapy after the first(n=2) and second operation(n=3). Three did not shown recurrence for the 13, 29 and 33 months. Conclusion: Post-operative prognosis of arterial manifestation of Behcet's syndrome was not encouraging and if possible, other treatment strategy should be considered.

Purpose: The aim of this study was to evaluate the clinical results of postoperative radiotherapy for parotid gland malignancy, and determine prognostic factors for locoregional control and survival. Materials and Methods: Between 1980 and 2002, 130 patients with parotid malignancy were registered In the database of the Department of Radiation Oncology, Seoul National University Hospital. The subjects of this analysis were the 72 of these 130 patients who underwent postoperative Irradiation, There were 42 males and 30 females, with a median age of 46.5 years. The most common histological type was a mucoepidermoid carcinoma. There were 6, 23, 23 and 20 patients in Stages I, II, III and IV, respectively. The median dose to the tumor bed was 60 Gy, with a median fraction size of 1.8 Gy. Results: The overall 5 and 10 year survival rates were 85 and $76\%$, respectively, The five-year locoregional control rate was $85\%$, which reached a plateau phase after 6 years. Sex and histological type were found to be statistically significant for overall survival from a multivariate analysis. No other factors, Including age, facial nerve palsy and stage, were related to overall survival. For locoregional control, nodal involvement and positive resection margin were associated with poor local control. Histological type, tumor size, perineural invasion and type of surgery were not significant for locoregional control. Conclusion: A high survival rate of parotid gland malignancies, with surgery and postoperative radiotherapy, was confirmed. Sex and histological type were significant prognostic factors for overall survival. Nodal Involvement and a positive resection margin were associated with poor locoregional control.
