A 49-year-old female patient who had obstruction of superior vents cave(SVC) with SVC syndrome was successfully managed by bypass operation of superior vents cava with spiral vein graft. A composite spiral vein graft was placed between the right innominate vein and the right atrium to bypass the occluded SVC. The graft was constructed from the patient's own saphenous vein, which was split longitudinally and wrapped around a stent in spiral fashion and the edges of the vein were sutured together to form a large autogenous conduit. The patient was relieved o SVC obstructive symtoms and signs and discharged 21 days postoperatively without any complication.

Aortic arch aneurysm generally requires an urgent treatment due to the risk of catastrophic aortic rupture. However conventional surgery for aortic arch repair still carries significant risks of postoperative morbidity and mortality, especially in patients with old age. In an effort to correct the aortic pathology while minimizing the risks of complication, we performed a hybrid technique which comprises the off pump arch aortic stent grafting in an 86-old male patient with an aortic arch aneurysm.

An 1-month old female newborn was admitted to our hospital because of jaundice which occurred at 2 days after birth. Plain chest X-ray and chest CT revealed a collapsed right middle lobe and lobar emphysema was suspected. Right upper lobectomy of the lung was done and pathologic findings showed an infantile lobar emphysema. After the operation, the newborn was discharged without complication and was followed up through the out patient clinic. Infantile lobar emphysema is rare and male dominant. Left upper lobe of the lung is the most prevalent site. Patients with infantile lobar emphysema complain of respiratory symptoms. We report one case of infantile lobar emphysema on right upper lobe of lung, in a female with no respiratory symptoms.

Among the late postoperative complications of the acute dissection of aorta, the fistula between dilated distal aorta and pulmonary parenchym is so rare that only few case have been reported sporadically. Although the aortopulmonary fistula is one of a fatal condition that needs prompt surgical intervention, with an appropriate management it is well controllable condition. Early diagnosis and urgent surgical intervention is the only way to prevent catastrophic hemorrhage. We experienced a surgical management of aortoplumonary fistula which occurred between upper lobe of the left lung and distal aortic dilatation of previous aortic bypass graft which was performed for Debakey type I acute aortic dissection.

Bacterial endocarditis is a well-recognized complication of prosthetic valve replacement. Postoperative fungal endocarditis of aortitis has been reported with increasing frequency. Aspergillus endocarditis or aortitis following open heart surgery has been reported in several patients. The difficulty in the diagnosis of this type of infection, the problems of therapy of prosthetic valve endocarditis0 and the relative ineffectiveness of antifungal agents account for the high mortality. Recently, we have experienced a patient with aspergillus aortitis after replacement of mitral valve. The diagnosis was finally established by histotogical examination of emboli removed from the femoral artery. The patient died after second open heart surgery for replacement of ascending aorta.

Subvalvular aortic stenosis developed after patch closure of perimembranous'VSD is rarely reported. A 18-month-old, 8 kg child with this complication after VSD closure 8 months ago in other hospital has been treated medically and was admitted to this hospital because of severe cardiomegaly and sign of heart failure. Cardiac catheterization revealed 55 mmHg of pressure gradient between aorta and LV cavity. We report one successful redo case of surgically relieved subvalvular aortic stenosis in a child after patch closure of perimembranous VSD.

Thymic cysts are uncommon tumors which usually occur in the neck and mediastinum. It is known to arise from embryonic remnants of the thymopharyngeal duct or from infammation of thymic tissues. Patients with thymic cyst are often asymptomatic and identified after surgical removal and histologic examination. We experienced a 73 year-old man with recently developed dyspnea. During the examination, chest CT showed a $5{\times}6cm$ sized cystic mass causing deviation of the trachea. It was located in between the right thyroid gland and anterior mediastinum. It also caused tracheal narrowing noted by bronchoscopy. Right anterior cervical incision and removal of the mass was performed and a histological diagnosis of thymic cyst was confirmed. The patient was discharged without complication.

Twenty-three patients with aneurysm were operated between Jan. 1956 to July 1983 at the Department of Thoracic surgery, Seoul National University Hospital. There were 18 males and 5 females in this series. The age ranged from 14 to 68 years with the mean age of 41 years. The etiology of aortic aneurysms was atherosclerosis in 10, trauma in 2, annuloaortic ectasia in 4, syphilis in 1, and unknown etiology in six cases. Among the 4 patients with ascending aortic aneurysm, aortic valve replacement with aneurysmorrhaphy in three patients and Bentall operation in one patient were performed successfully. One patient with entire aortic arch aneurysm was received Dacron graft replacement with anastomosis of brachiocephalic arteries separately under cardiopulmonary bypass. There was no complication. Among 6 patients involving the descending thoracic aorta, three patients were managed by prosthetic bypass graft and aneurysm resection, and another three patients were also managed by prosthetic graft replacement. There were three hospital deaths. There were two thoracoabdominal aortic aneurysm. One patient in shock state due to preoperative rupture died from cardiac arrest during operative procedure. In another patient who had extensive involvement from the midportion of descending thoracic aorta to the terminal abdominal aorta, the aneurysm was successfully repaired with Dacron graft. In this instance celiac axis, superior and inferior mesenteric arteries and right renal artery were anastomosed separately. Eight of the 10 abdominal aortic aneurysms was replaced with prosthetic graft. One saccular aneurysm was treated by resection and primary closure. In another patient, cardiac arrest occurred during operation before definitive procedure. There was one another hospital death in the patient with preoperative rupture.

Coronary ostium obstruction due to dislodgement of the prosthetic valve is a rare and life-threatening complication, and particular caution is required for sutureless aortic valve replacement (AVR) with concomitant valvular surgery. In general, coronary artery bypass surgery is performed when coronary ostium obstruction occurs after AVR, but other options may need to be considered in some cases. Herein, we present a case of coronary artery occlusion in an 82-year-old female patient who had undergone AVR and mitral valve replacement for aortic valve stenosis and mitral valve stenosis at the age of 77 years. A hybrid procedure involving redo AVR and percutaneous coronary intervention after left main coronary ostium endarterectomy was performed. To summarize, we present a case of hybrid AVR in a patient with coronary artery obstruction after AVR that was successfully managed using this method.

Background: The clinical value of 3-field lymph node dissection (3FLND) in esophageal squamous cell carcinoma (ESCC) remains controversial. This study aimed to identify the patterns and prognostic significance of cervical lymph node metastasis (CLNM) in ESCC. Methods: A retrospective review of 77 patients with E SCC who underwent esophagectomy and 3FLND between 2002 and 2016 was conducted. For each cervical node level, the efficacy index (EI), overall survival, recurrence rate, and complication rate were compared. Results: CLNM was identified in 34 patients (44.2%) who underwent 3FLND. Patients with CLNM had a significantly lower overall survival rate (22.7% vs. 58.2%) and a higher recurrence rate (45.9% vs. 16.3%) than patients without CLNM. CLNM was an independent predictor of recurrence in ESCC patients. Moreover, in patients with pathologic N3 tumors, the odds ratio of CLNM was 10.8 (95% confidence interval, 2.0 to 57.5; p=0.005). Level IV dissection had the highest EI, and level IV metastasis was significantly correlated with overall survival (p=0.012) and recurrence (p=0.001). Conclusion: CLNM was a significant prognostic factor for ESCC patients and was more common among patients with advanced nodal stages. Level IV exhibited the highest risk of metastasis, and dissection at level IV may be crucial when performing 3FLND, especially in advanced nodal stage disease.
