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.

Pneumothorax-either spontaneous or iatrogenic-is commonly encountered in pulmonary medicine. While secondary pneumothorax is caused by an underlying pulmonary disease, the spontaneous type occurs in healthy individuals without obvious cause. The British Thoracic Society (BTS, 2010) and the American College of Chest Physicians (ACCP, 2001) published the guidelines for pneumothorax management. This review compares the diagnostic and management recommendations between the two societies. Patients diagnosed with primary spontaneous pneumothorax (PSP) may be observed without intervention if the pneumothorax is small and there are no symptoms. Oxygen therapy is only discussed in the BTS guidelines. If intervention is needed, BTS recommends a simple aspiration in all spontaneous and some secondary pneumothorax cases, whereas ACCP suggests a chest tube insertion rather than a simple aspiration. BTS and ACCP both recommend surgery for patients with a recurrent pneumothorax and persistent air leak. For patients who decline surgery or are poor surgical candidates, pleurodesis is an alternative recommended by both BTS and ACCP guidelines. Treatment strategies of iatrogenic pneumothorax are very similar to PSP. However, recurrence is not a consideration in iatrogenic pneumothorax.

Background: It has recently become most general to use the small bore catheter to perform closed thoracostomy in treating iatrogenic pneumothorax. This study was performed for analysis of the efficacy of treatment methods by using small bore catheter such as 7 F (French) central venous catheter, 10 F trocar catheter, 12 F pigtail catheter and for analysis of the appropriateness of each procedure. Materials and Methods: From March 2007 to February 2010, Retrospective review of 105 patients with iatrogenic pneumothorax, who underwent closed thoracostomy by using small bore catheter, was performed. We analyzed the total success rate for all procedures as well as the individual success rate for each procedure, and analyzed the cause of failure, additional treatment method for failure, influential factors of treatment outcome, and complications. Results: The most common causes of iatrogenic pneumothorax were presented as percutaneous needle aspiration(PCNA) in 48 cases (45.7%), and central venous catheterization in 26 cases (24.8%). The mean interval to thoracostomy after the procedure was measured as 5.2 hours (1~34 hours). Total success rate of thoracostomy was 78.1%. The success rate was not significantly difference by tube type, with 7 F central venous catheter as 80%, 10 F trocar catheter as 81.6%, and 12 F pigtail catheter as 71%. Twenty one out of 23 patients that had failed with small bore catheter treatment added large bore conventional thoracostomy, and another 2 patients received surgery. The causes for treatment failure were presented as continuous air leakage in 12 cases (52.2%) and tube malfunction in 7 cases (30%). The causes for failure did not present significant differences by tube type. Statistically significant factors affecting treatment performance were not discovered. Conclusion: Closed thoracostomy with small bore catheter proved to be effective for iatrogenic pneumothorax. The success rate was not difference for each type. However, it is important to select the appropriate catheter by considering the patient status, pneumothorax aspect, and medical personnel in the cardiothoracic surgery department of the relevant hospital.

Iatrogenic ureteral injury is a complication that can occur during a variety of pelvic or abdominal surgeries. The most frequent causes are gynecological ones, followed by colon and vascular surgeries. Management of ureteric injury depends on the time of diagnosis and the severity of organ damage. Injuries diagnosed intraoperatively should be treated immediately. Occasionally, intraoperative ureteral injury is overlooked, and symptoms of the late diagnosis of ureteral injury are usually nonspecific; therefore, the diagnosis is delayed for days or weeks postoperatively. Management of injuries diagnosed postoperatively is more complex. There are differing opinions on whether an initial conservative or immediate operative intervention is the best line of action. Delayed repair is suggested on the grounds that it will reduce inflammation and tissue edema. However, many authors are in favor of early repair, perhaps because tissue planes are easier to find before fibrosis becomes too dense. Ureteral injuries occurring at the level of the pelvic brim should be best managed with an end-to-end anastomosis, preferably around a ureteric stent. More distal injuries also should be ideally managed with an end-to-end anastomosis, after excision of the crushed or compromised segments. However, if the remaining distal segment is short, ureteral reimplantation is the procedure of choice. The Boari flap technique for ureteral reimplantation is invaluable in cases with a short proximal segment. Delayed recognition of iatrogenic ureteral injury may be associated with serious complications, so prompt recognition of ureteral injuries is important. Recognition of the injury before closure is the key to easy, successful, and complications-free repair. Increased awareness of the risk for ureteral damage during certain operative maneuvers is vital to prevent injury, and to decrease the incidence of iatrogenic injury. A sound knowledge of abdominal and pelvic anatomy is the best prevention.

Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures should be taken by dentist. A patient visited the clinic with the chief complaint of 'My lower teeth bite the palate and it hurts'. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.

Chylothorax is a rare disease and massive lymph fluid loss can cause life-threatening condition such as severe malnutrition, weight loss, and impaired immune system. If untreated, mortality rate of chylothorax can be up to 50%. This is a case report of a 3-year-old child with iatrogenic chylothorax. Despite conservative treatment and procedures, like perm catheter insertion, the patient failed to improve the respiratory symptoms over 3 months of period. As an alternative to surgical option, such as pleurodesis and thoracic duct ligation which has high complication rate, the patient underwent lymphovenous anastomosis (LVA) and lymph node to vein anastomosis (LNVA). Follow-up at fourth month showed clear lungs without breathing difficulty despite perm catheter removal. This is the first report to show the effectiveness of LVA and LNVA against iatrogenic chylothorax.

Intussusception after colonoscopy is an unusual complication. A MEDLINE search revealed only 7 reported cases. We present a report of a 28-year-old man who developed abdominal pain several hours after routine colonoscopy and in whom computed tomography (CT) revealed colocolic intussusception. We postulate that this condition is iatrogenic and induced by suctioning of gas on withdrawal of the colonoscope. A common observation among the reported cases was abdominal pain several hours after colonoscopy and right-sided intussusception. All cases had colonoscopy reaching the right side of the colon. Treatment for adult intussusception remains controversial with regard to reduction versus resection, especially given the high association with a pathological cause and malignancy. Among the 8 reported cases, only the current case did not require surgery. A combination of benign colonoscopy, CT, and the clinical picture should provide sufficient information to initially choose a more conservative treatment approach.

Percutaneous nephrostomy is relatively safe for temporary urinary diversion. However, colonic perforation due to percutaneous nephrostomy can happen with an incidence of 0.2% as reported in the English literatures. To our knowledge, this is the first case being reported as a complication following treatment for traumatic renal injury. This paper is to share our treatment approach which differs from the usual approach according to existing literatures. We report on a young man who sustained grade IV renal injury due to blunt trauma and was managed conservatively. The treatment of traumatic renal injury via urinary diversion was complicated with an iatrogenic colonic perforation. The management and subsequent treatment of this patient is discussed in this case report.

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.
