Iatrogenic suclavian artery aneurysm is a rare disease which requires surgery because of the dangers of a rupture. We report a case of an aneurysm of the right subclavian artery developed by an iatrogenic trauma in a 43-year-old male. The preoperative diagnosis was made by an angiography and Doppler ultrasonogram. After the resection of a 6${\times}$7 cm sized aneurysm, an end to end anastomosis was done with a 6 mm Gore-Tex vascular graft. The post-operative course was uneventful and has been followed up from 3 months after discharge.

Spontaneous neonatal esophageal perforation (EP) is a rare condition. However, iatrogenic EP due to a feeding tube is not uncommon, particularly in premature infants. Iatrogenic EP can result in serious complications, such as a pneumothorax, and can be fatal. Usually a pneumothorax develops as a result of EP. However, we experienced an EP in a patient with a pneumothorax. The EP occurred after inserting a feeding tube while the patient was suffering from a pneumothorax. Thus care is needed when inserting the feeding tube in a patient with a pneumothorax.

Iatrogenic calcinosis cutis is due to the intravenous administration of calcium gluconate or calcium chloride to treat hypocalcemia. The arthors report three cases of calcinosis cutis with calcifications involving the upper or lower extremities in neonates following the extravasation of calcium gluconate. Three neonates, a 2-week-old girl, 4-week-old boy, and a 4-week-old girl, were consulted for indurated nodules after the intravenous administration of calcium gluconate at the intensive care unit. Complete remission of palpable nodule and calcification was observed on the radiograph at three weeks, four weeks and six months after the initial presentation in each. All three neonates with iatrogenic calcinosis curtis were resolved spontaneously without functional and cosmetic complications. According to enhancement of the patient's cognition about benign disease, a suitable explanation of the disease and avoiding unnecessary treatment through an early diagnosis of iatrogenic calcinosis cutis will reduce a number of potential medical malpractice disputes.

식도 천공의 치료는 최근 치료법의 발전에도 불구하고 여전히 난해한 문제이다. 이 환자들은 천공의 원인이나 위치, 심한 정도가 다양한 이질적인 군이며, 반수 이상이 이미 식도에 기존의 질환을 가지고 있어 문제를 더욱 복잡하게 한다. 따라서 절대적이고 획일적인 치료방법은 아직 확립되어 있지 않으며 많은 다양한 방법들이 제시되고 있다. 2002년 11월부터 2003년 7월까지 총 8명의 환자가 식도 천공으로 동아대학교병원 흥부외과에서 치료를 받았으며, 원인별로는 의인성(iatrogenic) 손상이 6례, 자발성(spontaneous) 손상이 2례였고 부위별로는 경부가 3례, 흥부가 5례였다. 의인성 손상에는 내시경 검사중 정상 경부 식도에 발생한 1례, 부식성 식도협착 환자의 풍선 확장술과 스텐트 삽입시 흉부 식도에 발생한 경우가 각각 1례씩, 외상성 경추손상의 수술시 정상 경부 식도에 발생한 경우가 2례, 선천성 식도폐쇄증(esophageal atresia)의 술후 문합부 누출이 생긴 경우가 1례 있었으며, 자발성 손상에는 하부식도에 발생한 기압성(barogenic) 손상 1례와 상흉부 식도암 천공 1례가 있었다. 경부 식도 천공 3례는 모두 경부 배액(drainage)과 식이용 장루술(feeding jejunostomy)을 시행하였고, 부식성 식도협착이 있던 환자 2례는 식도절제술과 흉부내 식도-위 문합을 시행하였으며, Boerhaave씨 증후군 환자는 1차 봉합술, 술후 문합부 유출이 있었던 환자와 식도암 천공이 있었던 환자는 식도절제 및 경부 식도루(esophagostomy), 배액용 위루(gastrostomy), 식이용 장루술을 시행하였다. 모든 환자는 패혈증 등의 심각한 합병증으로의 진행 없이 회복되었다. 현재 위장관의 연속성이 유지 혹은 복원된 환자는 경구식이 중이며 그 외의 환자들은 장루를 통해 영양을 공급하며 식도재건술을 기다리고 있다. 식도 천공은 최근 항생제의 사용, 과영양요법(hyperalimentation), 술후 환자관리의 개선 등으로 치료에 많은 발전이 있었으나, 치료 방침에 있어서는 여전히 논란이 있으며 높은 사망률을 보이는 난제로 남아있다. 비록 일반적인 지침이 도움이 되겠지만, 치료 방침은 환자 개개인의 상황에 따라 적절하게 선택해야 하며, 임상경과에 따라 언제라도 방침을 변경할 수 있는 유연함이 필요하리라 생각한다.

This patient was an 53-year-old man who had undergone Sengstaken-Blackmore tube insertion for esophageal varix bleeding. Two days after Sengstaken-Blackmore tube insertion, he developed severe left hemothorax and was transferred to our hospital. The esophagoscopic findings revealed a large perforation lengthening 8-cm in the intrathoracic esophagus. A left thoracotomy was performed 33 days after the injury due to repeated varix bleedings and poor conditions. An 8-cm longitudinal perforation of the intrathoracic esophagus with gross suppurative empyema was found. Primary repair and esophageal exclusion was performed 2cm proximal and distal to the perforation, using rows of nonabsorbable staplers(TA stapler 60 $\times$ 4.8) and large bore thoracostomy tubes were placed for local drainage. Six days after intrathoracic esophageal exclusion, an esophagogram revealed a leakage at just above the proximal stapling site. A cervical esophageal exclusion was performed using the same method. One hundred thirty seven days after exclusion operation for the intra-thoracic esophageal perforation, the patient was able to eat per orally without any secondary esophageal reconstructive surgery.

Hepatic artery pseudoaneurysm is a rare but potentially life-threatening condition that usually occurs after trauma. Early recognition and prompt management are essential for preventing catastrophic consequences, such as hemoperitoneum. We report a rare case of liver abscess caused by Klebsiella oxytoca resulting in hepatic artery pseudoaneurysm without iatrogenic injury. The unique feature of the present case is that the abscess cavity itself became a pseudoaneurysm as a result of fistula formation with the hepatic artery. Vascular complications should be considered in patients with unfavorable clinical course even in the absence of iatrogenic injury. Endovascular treatment is safe and effective.

Coracoid impingement syndrome results from abnormal contact between the anterosuperior humerus and the coracoacromial arch. The coracoid impingement may occur from traumatic, idiopathic, or iatrogenic causes. Traumatic causes of coracoid impingement include fractures of scapular neck, coracoid process or lesser tuberosity. Coracoid impingement due to lesser tuberosity malunion is a rare disease and most of them were treated by open procedures. The authors present a case of coracoid impingement caused by malunion after isolated lesser tuberosity fracture which was treated by arthroscopic coracoplasty with percutaneous screw fixation.

Background: Perforation of esophagus is relatively uncommon. but it is associated with high morbidity and mortality. Treatment and outcome are largely determined by the time of presentation. We performed a retrospective review of patients with esophageal perforation to assess the outcome of current management techniques. Material and Method: A retrospective chart review was performed on all patients treated for perforation of esophagus from March 1990 to March 2005. There were 28 patients (22 men and 6 women: mean age 51 years, range 17 to 82 years) The causes of the perforations were as follows: foreign body retention (9 patients), trauma (7 patients), spontaneous rupture (7 patients), and iatrogenic (5 pati-ients). 18 patients were presented within 24 hours and 10 patients were presented after 24 hours., Esophageal repair was performed in 21 ($75\%$) of them, 4 patients were treated with esophagectomy, 3 patients were treated with feeding gastrostomy and drainage. Result: Hospital mortality was $18\%$ and iatrogenic was increase the mortality rate (p < 0.05). Site of perforation, time from perforation, and treatment method had no influence on mortality. Postoprative leaks occurred in 4 patients after primary repair and were treated conservatively. Conclusion: Esophageal perforation remains a devastating event which is difficult to diagnose and manage. Primary repair can be performed in most patients with esophageal perforation regardless of time to presentation with a low mortality. Accurate diagnosis and early treatment are essential to the successful management of patients.

An ilio-iliac arteriovenous fistula (AVF) is rare. Common factors leading to ilio-iliac AVF include congenital malformations, iatrogeny, and trauma. There is limited documentation in the literature of cases involving ilio-iliac AVF with May-Thurner syndrome. Here, we present a case of an ilio-iliac AVF with May-Thurner syndrome in an 80-year-old male. CT and angiography confirmed extensive ilio-iliac AVF. Successful endovascular procedures for ilio-iliac AVF were performed using several variable-sized coils and 1400-2000 ㎛ gelatin particles. After embolization, follow-up abdominopelvic CT revealed an improvement in edema in the left leg.

Infective endocarditis that involves the right side of the heart has been estimately 5% of all cases of infective endocarditis. It has been shown that about 70% of right-sided heart infective endocarditis cases have preexisting congenital heart disease or acquired valvular lesion. It would occur in intravenous drug users or end-stage renal disease patients with indwelling venous dialysis catheter. Antibiotic therapy is more effective in the right and, when it fails, the consequence of valve disruption and emboli are less. Patients receiving long-term hemodialysis are a unique population with regard in the risk of bacteremia and subsequent infective endocarditis. We experienced one case of the active infective endocarditis with right atrial vegetation without tricuspid or pulmonary valve involvement in patient with end-stage renal disease receiving long-term hemodialysis, who needed surgical correction after medical treatment failure. Then we reported it with references that right-sided heart infective endocarditis is rare, but difficult to diagnose, life-threatening because of delayed medical treatment.
