Varicose veins usually present in the superficial veins of the lower extremities and are one of the main clinical presentations of chronic venous disease (CVD). Patients' symptoms may vary according to the pathophysiology, location, and severity of CVD. The prevalence of CVD in Korea has been increasing gradually. However, due to its broad clinical spectrum and the subjective nature of its diagnosis using ultrasound, discrepancies in diagnostic and treatment quality may exist among treating physicians. There have been recent efforts to improve the quality of the diagnosis and treatment of varicose veins in Korea by standardizing the diagnostic criteria and the indications for treatment. This study is a comprehensive review of the clinical manifestations and diagnostic criteria of CVD based on the most recent international and domestic guidelines and reports.

A 47-year-old male with hypertension, diabetes mellitus and heavy smoking, but no anginal symptoms, presented with claudication of the lower extremities. Extremity angiography with coronary angiography revealed peripheral arterial lesions including a left subclavian artery occlusion with coronary artery disease. The patient underwent an initial off-pump coronary artery bypass with an ascending aorto-axillary bypass. The right internal mammary artery was anastomosed to the left anterior descending coronary artery. The greater saphenous vein graft was connected from the ascending aorto-axillary bypass graft to the diagonal branch. At postoperative day 18, femorofemoral and bilateral femoropopliteal bypasses were performed. We report a case of the combined repair of coronary artery disease and a left subclavian artery occlusion.

A 46-year-old man presented with a lateral thoracic meningocele associated with cutaneous neurofibromatosis type I and kyphoscoliosis of the thoracic spine upon medical examination. In the majority of such cases, these meningoceles remain asymptomatic, but surgery is indicated when giant or symptomatic cysts are present. The large thoracic meningocele was successfully extirpated through the transthoracic approach in combination with lumbar puncture and cerebrospinal drainage for decompression of the cyst.

Between 1985 and 1993, 29 children from 1 to 15 years of age have undergone cardiac valve replacements at Buchon Sejong Hospital. The patients were composed of 20 males and 9 females and 17 patient had congenital heart disease and 12 patients had acquired heart disease. Two of these patients have had second valve replacements due to paravalvular leakage and valve thrombosis. Single valve replacements were 29 and double valve replacements were 2. All the patients had received prosthetic valves except one. Among the 25 patients who had definite post-operative records, the overall mortality was 12%[4% was early mortality and 8% was late mortality].25 patients were followed up with coumadin anticoagulation for total 633 patient-months[minimum 2 months to maximum 93 months, mean 25.3 months] and actuarial survival rate was 88.5 $\pm$ 6.3% at 7 years and event free rate was 70.3 $\pm$ 11.7% at 7 years. These results suggest that pediatric valve replacements can now be performed at a low operative risk although various problems are still remained and the choice of valve is prosthetic valve mainly due to its durability at the present time.

Type II chronic dissecting thoracoabdominal aortic aneurysms are a surgically challenging disease. The conventional thoracoabdominal aortic aneurysm repair technique using cardiopulmonary bypass is a high-risk procedure. However, a recently developed endovascular technique may be an alternative treatment for the disease, but faces the obstacle of lesional restriction. This new technique uses a hybrid strategy to overcome the limits of endovascular thoracoabdominal aortic aneurysm repair. Herein, we report on a successful outcome after performing the hybrid visceral debranching procedure.

Surgery remains the standard treatment for resectable thoracic esophageal cancer but that is justified only when acceptably low morbidity and mortality rates can be achieved even for advanced disease. The appropriate extent of resection to achieve the best outcome is the most controversial aspect of treating esopahgeal cancer and the optimal excent of lymphadenectomy also remains controversial. Until data from prospective randomized trials showing a clear benefit using a particular approach are available, surgeons should perform their better judgement in individualizing and selecting the most appropriate surgical approach to provide the best chance of cure or lasting palliation for this disease that challanges both patient and surgeon. Further studies are necessary to examine the utility and efficacy of each approach in treating thoracic esophageal cancer either alone or in combination with other modalities.

Dissecting aortic aneurysm is a disease which is characterized by hemorrhagic intramural seperation of aortic wall and extension for varlng distances proximally, distally, or both from the site of the intimal tear. Most aortas show some type of medial degeneration most commonly described as cystic medial necrosis. DeBackey classified this disease according to involved aorta and site of intimal tear to 3 basic types, such as type I, II and III. Type III is defined that dissecting process arrises in the descending thoracic aorta just distal to origin of the left subclavian artery and extends distally for a varing distance. We expirienced a case of dissecting aneurysm, type III of DeBackey's classification which dissecting process is limited to the descending thoracic aorta in the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. This patient was 40 year old woman and she had suffered from intermittent sharp back pain for 3 years .before admission. Excision of the aneurysm and Dacron graft were placed successfully under the left atrio-femoral bypass with artificial pump. The hospital course was uneventful.

Background: A raised carcinoembryonic antigen (CEA) may be associated with significant pathology during the postoperative follow-up of lung adenocarcinoma. Methods: We reviewed the medical records of 305 patients who underwent surgical resections for primary lung adenocarcinoma at a single institution between April 2006 and February 2013. Results: Preoperative CEA levels were significantly associated with age, smoking history, pathologic stage including pT (pathologic tumor stge), pN (pathologic nodal stage) and overall pathological stage, tumor size and differentiation, pathologically positive total lymph node, N1 and N2 lymph node, N2 nodal station (0/1/2=1.83/2.94/7.21 ng/mL, p=0.019), and 5-year disease-free survival (0.591 in group with normal preoperative CEA levels vs. 0.40 in group with high preoperative CEA levels, p=0.001). Preoperative CEA levels were significantly higher than postoperative CEA levels (p<0.001, Wilcoxon signed-rank test). Postoperative CEA level was also significantly associated with disease-free survival (p<0.001). A follow-up serum CEA value of >2.57 ng/mL was found to be the appropriate cutoff value for the prediction of cancer recurrence with sensitivity and specificity of 71.4% and 72.3%, respectively. Twenty percent of patients who had recurrence of disease had a CEA level elevated above this cutoff value prior to radiographic evidence of recurrence. Postoperative CEA, pathologic stage, differentiation, vascular invasion, and neoadjuvant therapy were identified as independent predictors of 5-year disease-free survival in a multivariate analysis. Conclusion: The follow-up CEA level can be a useful tool for detecting early recurrence undetected by postoperative imaging studies. The perioperative follow-up CEA levels may be helpful for providing personalized evaluation of lung adenocarcinoma.

Chronic pulmonary obstructive disease is known to be a significant risk factor for mortality in patients who under-went operation for abdominal aortic aneurysm. To decrease perioperative respiratory complication in these patients, maintenance of self respiration as possible is one of the better method. A seventy-seven year old male patient complained of abdominal pain and he was diagnosed for 9 cm sized abdominal aortic aneurysm. But he had severe chronic obstructive pulmonary disease which was expected to increase surgical mortality. So we introduced epidural anesthesia with maintenance of self respiration and performed surgical resection and graft replacement of abdominal aorta, and he recovered without any complication.
