Post-intubation tracheoesophageal fistula is rare, and its management causes a serious problems to surgeons. We have experienced 4 cases in 3 patients. Simple ditcision and closure of the fistulas were done by trans-cervical approach after weaning of ventilator. The tracheal defect was closed by simple suture, and the esophageal defect was closed in two layers before a viable muscle flap was interposed between the two suture lines in order to prevent recurrence. There was one delayed tracheal stenosls and one recurrent fistula, and these complications were also managed success ully.

Postoperative empyema thoracis with bronchopleural fistula (BPF) Is uncommon but serious complication. The management remains troublesome area in the field of the general thoracic surgery During the period of October 1993 to December 1994, four patients with postresectional empyema thoracic with BPF were treated consecutively in Ewha Womans University Mokdong Hosp tal. The treatment procedures include irrigation and debridement of the empyema cavity and muscle flap transposition. Follow-up periods after surgery were 4-12 months. Three patients were thought successful, one patient failed. We think that the cause of failure is muscle necrosis of rectos abdominis muscle flap due to vascular injury and infection of muscle due to residual infected debridement of empyema cavity.

The surgical managements for the complicated aortic disease is still one of most challenging fields for the cardiac surgeons. The endovascular stent graft procedure has been tried recently to avoid serious complications caused by traditional graft replacement technique. However, indications for the procedures or management methods for the complications have not been clearly elucidated so far. We report a case of successful management for the newly-onset aneurysmal dilation of the distal aorta after an endovascular stent graft procedure in a patient with acute aortic dissection type IIIB.

Angiofollicular lymph node hyperplasia (AFLNH) with well marginated lymphoid masses, is a rare benign disease of unknown etiology. The majority of the disease develop intrathoracically. Histologically this disease can be divided into the hyaline-vascular and the plasma cell types with the hyaline-vascular type prevailing. The plasma cell variant has been associated with nephrotic syndrome, anemia, growth failure, fever, hyperglobulinemia, peripheral neuropathy, and hypoalbuminemia. Surgical resection is known to be treatment of choice in most cases, and radiotherapy is reserved for advanced, unresectable lesions. We report a complete remission of AFLNH in a case treated by sugical excision followed by irradiation.

Background: Radiofrequency obliteration and endovenous laser therapy of the greater saphenous vein have recently been introduced as alternative, minimally invasive techniques for the treatment of saphenous vein incompetence. The 7 Fr. VNUS $ClosureFAST^{(R)}$ radiofrequency obliteration system was introduced in Gwang-Ju Veterans hospital. The purpose of this study is to evaluate the efficacy and complications of radiofrequency obliteration using the 7 Fr. VNUS $ClosureFAST^{(R)}$ system. Material and Method: Between May 2, 2007 and May 31, 2008, we performed radiofrequency obliteration on 90 patients. The number of males was 67 and their mean age was $57.9{\pm}11.0$ (range: $23{\sim}78$) years old. The patients underwent follow up exams at 3 weeks after the procedures and then every 3 months. The effects of treatment and the complications were reviewed. Result: The postoperative complications were ecchymosis (94.4%), pain (27.8%), paresthesia (25.6%), bullous formation (8.9%), edema (6.7%) and phlebitis (2.2%). One patient showed good blood flow after 3 weeks and one patient showed good blood flow after 3 months. The one-year success rate of radiofrequency obliteration in varicose veins was 97.6%. Conclusion: Our data showed acceptable operative results and short-term clinical results for treating varicose veins with radio frequency obliteration. Long-term follow-up and comparison of radio frequency obliteration with high ligation and stripping, previous radiofrequency ablation and endovenous laser therapy are needed in the future.

Pulmonary artery sarcoma is a rare disease and hard to diagnose; therefore, suspicion is very important for the diagnosis and treatment. Surgical resection is almost always needed because of progressive right heart failure. Adjuvant chemotherapy and radiation therapy are still controversial. We report a case of a 42-year-old man who had a right pulmonary arterial tumor Curative resection was impossible because the tumor invaded the left pulmonary artery. Palliative endarterectomy was performed followed by radiation therapy. The patient refused the chemotherapy. Until the postoperative 6th month, the residual tumor was stable. However, 15 months later, follow-up chest computed tomography revealed a metastatic pulmonary nodule at left lower lobe and the increased residual tumor. The patient received chemotherapy with limited tumor response. The metastatic nodule and residual tumor did not increase but bone scan revealed a rib metastasis at postoperative 24 months. He will be receiving additional chemotherapy.

Renal artery injury is a rare complication in blunt trauma, but can cause devascularization of the kidney, leading to renal failure. It requires early diagnosis and management. The treatment of renal artery injury still remains controversial, but recent studies have reported the successful treatment outcome with endovascular stent placement. Nevertheless, there is no standard treatment strategy in cases of pediatric patients. We report a case of a 16-year-old girl with right renal artery occlusion associated with a grade IV liver laceration. She was treated with only balloon angioplasty, and the kidney showed marked improvement of parenchymal perfusion with normalized renal function. Treatment with only balloon angioplasty can be a treatment option in pediatric patients with renal artery injury.

신장내과를 전문 과목으로 선택하여 대학병원에서 10여년 가까이 환자를 진료하면서 아침에 회진을 할 때면 저는 전공의 들에게 "어제 입원한 환자는 당뇨병성 신증 환자인가"라고 먼저 묻는 경우가 많습니다. 그 이유는 당뇨병으로 합병된 신장병, 혹은 당뇨병환자에서 혈관질환과 감염 질환이 동반될 경우 치료도 어렵고 임상 경과가 악성 경과를 밟으며 예후가 좋지 않기 때문입니다. 또한 당뇨병으로 인한 말기 신부전증이 최근 무섭게 증가되고 있기 때문이기도 합니다. 따라서 당뇨병성 신증의 조기 발견과 적절한 치료는 아무리 강조해도 지나침이 없습니다. 저는 여기서 최근 가장 가슴이 아팠던 사례를 간단히 소개하고 당뇨병성 신증의 원인, 예방과 치료를 서술하고자 합니다.

Endovascular treatment of the aortic aneurysm with a stent graft is rapidly evolving. We describe here a case of hybrid TEVAR (thoracic endovascular aortic repair) in which the stent grafts were placed in the aortic arch after debranching of the arch vessels. The patient had undergone ascending aorta replacement for acute type I aortic dissection 2.5 years earlier. The aneurysmal change of the distal dissection progressed with time. A provisional bypass surgery from the ascending aorta to the innominate artery and left carotid artery was performed and then stent grafts were inserted via an antegrade route that covered the whole aortic arch and proximal descending thoracic aorta.
