RESUMO
BACKGROUND: The right gastroepiploic artery(RGEA) has been use in coronary artery bypass grafting from 1987. The RGEA is the most useful arterial conduit in coronary artery bypass grafting(CABG) followed by the internal mammary artery, MATERIALS AND METHOD: From Septermber 1998 to February 1999 the RGEA was used for coronary artery bypass grafting in 11 patients 10 males and 1 female. Postoperative angiography was performed in all of the patients before discharge RESULT: Early patent rate of the RGEA was 100%. The flow competition of the REGA graft was seen in 4 patients(36.4%) The flow pattern war RGEA dependent type in the inner diameter of the recipient coronary artery 1.5 mm the inner diameter of the RGEA 2.5 mm and the rtio of inner diameter of the RGEA and the recipient coronary artery 1(p<0.05) CONCLUSION: Early results of CABG with RGEA was satisfactory. However the RGEA graft has a tendency of flow competition in relation to the inner diameter of graft. Preoperative angiographic evaluation for RGEA and meticulous operative technique are required for a good surgical results.

BACKGROUND: The surgical indications of stage IV non-small cell lung cancer(NSCLC) are extremely limited with its controversial results. We analyzed the surgical results and survival in selected patients with resectable stage IV NSCLC. MATERIAL AND METHOD: We reviewed the medical records of 21 patients who underwent operation for stage IV NSCLC from Jan. 1992 to Sep. 1999. RESULT: The mean age of patients was 55.6 years(range: 35 to 78). Sixteen were men and 5 were women. Tissue types were squamous cell carcinoma in 10(45.5%), adenocarcinoma in 9(40.9%), large cell carcinoma in 1 and carcinosarcoma in 1. Distant metastatic lesions were ipsilateral other lobe of lung in 18, brain in 2 and adrenal gland in 1. Pneumonectomy was performed in 16 patients, bilobectomy in 3, and lobectomy in 2 who underwent previous operatin for brain metastasis. Mean follow-up duration was 21.2+/-17.7 months. During follow-up period, 13 patients died. Three-and 5-year survival of patients were 38.0% and 19.0%, the median survival time was 19.1+/-7.8 months. In the group with ipsilateral pulonary metastasis(PM, n=18), 3- and 5-year survival of patients with N0 and N1(n=9) disease were 64.8% and 32.4%, median survival time was 55.3+/-27.2 months. Three-year survival of patients with N2(n=9) disease was 11.1%, median survival time was 10.6+/-0.3 months. The survival of N0 and N1 disease group was significantly better than that of N2 disease group(p=0.042). Also the disease free survival of N0 and N1 was significantly better than that of N2 disease in overall group(53.3 months vs 12.1 months, p=0.036) and ipsilateral PM group(63.4 months vs 8.8 months, p=0.001). CONCLUSIONS: We suggest that surgical treatment is worthful modality in well selected patients with stage IV NHSCLC especially with ipsilateral PM and N0 or N1 disease. Nevertheless our study indicate questions that will need to be experienced further in larger studies.

Mediastinal hemangioma is a rare tumor and only few cases have been reported in the literatures. We have experienced one case of cavernous hemangioma occuring at the superior vena cana. The patient was a thrity-five year old female with no specific symtoms except palpable cystic mass in the right cervical area. A routine chest radiography showed an upper mediastinal mass. Computed Tomography showed about 4x5 cm sized cystic mass communicating to the superior vena cava 2 cm above of the veno-atrial junction. After the evaluation, surgical excision was performed and the pathologic diagnosis was confirmed to cavernous hemangioma. Postoperative course was uneventful and the patient has been followed up without any problems.
