Purpose: As the care of surgical patients becomes increasingly complex and catheter-based techniques are more frequently applied, the pattern of iatrogenic vascular injuries may be increasing. Major vascular injuries can jeopardize a patient's life or limb survival. The purpose of this study was to examine the current etiology and prognosis for iatrogenic vascular injuries. Methods: We reviewed medical records of 29 cases of iatrogenic vascular injury that were treated Seoul National University Bundang Hospital between October 2003 and October 2008. We studied clinical variables including demographics, cause of injury, clinical presentations, management and prognosis. Results: The mean age was 60.8 years (range: 25-86), and the male to female ratio was 1.9 : 1. The causes of injuries were operation related complication in 18 cases (62.1%), endovascular intervention and diagnostic angiography in 11 cases (37.9%). The types of vascular injury were partial severance in 14 cases, pseudoaneurysm in 8, arteriovenous fistula (AVF) in 3, thrombosis in 2, complete severance in 2. Especially, device related complication including percutaneous closing device were occurred in 9 and the others came from inadvertent physician's procedure. Primary repair were done in 12 cases, end-to-end anastomosis in 5, interposition graft in 4, ligation in 2, patch angioplasty in 1, peudoaneurysm excision and arteriorrhaphy in 1, hematoma evacuation in 1, and endovascular repair in 3. There were 2 cases of mortality, one of them due to hemorrhagic shock and the other due to septic shock. Conclusion: Proper selection of treatment modalities should be important to have better outcome according to the type of injury as well as anatomical location. Each physician should be familiar to new device as well as patient's topographical feature. Immediate referral to vascular specialist is also essential to reduce morbidity.

Pure esophageal atresia without tracheoesophageal fistula is a uncommon form of congenital malformation of the esophagus, which is able to be suspected by fetal ultrasonograpy before delivery and diagnosed definitely by simple chest X-ray and esophagogram immidiately after delivery. We performed delayed primary repair in 2 cases of pure esophageal atresia by using stomach for conduit in one case and colon in the other case. But there were graft failure in the latter case, so reoperation was performed by using stomach. Postoperatively, two patients showed no stenosis and leakage in anastomotic site and were discharged in good oral intake without dysphagia.

기관식도루를 동반하지 않은 원간격결손 식도폐쇄증 1예를 미리 조성한 위루와 경구를 통하여 주기적 부지를 함으로써 식도길이를 확장하여 식도-식도단단문합술로 식도의 개통복원을 할 수 있었음을 경험하였다. 이때 상부식도맹단부로부터 이중관을 이용한 지속적인 섬프배액술이 경과에 아주 긴요하며, 수술시 식도길이의 여유를 위하여 식도근환상절개술을 한 후에는 근절개부위의 협착 발생 가능성에 항상 주의하여 술 후 조기(술 후 2-4주)에 추시함이 꼭 필요하다고 생각하였다. 식도부지를 할 때에는 길이 뿐만 아니라 직경확장(특히 하부식도에서)에도 관심을 갖이면 더욱 좋은 결과를 얻을 수 있다고 판단된다.

The labiomandibulotomy approch to the oral cavity and oropharygeal region was first described by Roux in 1836 and become popular for oral and oropharyngeal tumors in cases where there are no clinical and radiological signs of mandible invasion. Anterior labiomandibulotomy and swing procedure provides excellent access and facilitate a mandibular resection and subsequent repair. In last two years, 8 cases of oral and oropharyngeal tumors were treated by this approach at the Dept. of Oral & Maxillofacial Surgery, Holy Family Hospital, Catholic University of Korea. And we analyzed postoperative complications as well as functional evaluations, and the results were as follows; In 4 cases, marginal mandibulectomy were combined with labiomandibulotomy and in case of malignancies, neck dissection was performed simultaneously. In almost case, plate and miniscrew fixation was used for osteotomy sites. Histologic evaluation of the resection margins of the specimens revealed tumor free in all cases. The postoperative complications were occured in 3 cases, one case of nonunion, one case of orocutaneous fistula, and one case of wound dehisence. Occlusal stability, jaw movement and swallowing function were acceptable postoperatively in 3 months. From above results, we concluded that, this approach not only provides wide exposure, permitting radical removal of benign and malignant lesions but also preserves function with minimal complications.

To evaluate criteria, indications, and prognosis of the various reconstructive methods on the patients with intraoral soft tissue defect who had been treated at Dept. of Oral and Maxillofacial Surgery, Pusan National University Hospital from 2003 to 2005, we have reviewed the clinical data of the patients and analysed. The results were as follows: 1. Tongue flaps have been mainly applied on anterior portion of palate and maxilla. The survival rate was high percent, but the cooperation of patient was inevitable for the success. 2. Palatal mucosa rotational flaps were available on relative large defect on palate, oroantral fistula site. The side effect was a scaring band from secondary healing on denuded donor palate site. Sometimes the band came to be a hinderance to swallowing, phonation. 3. Forearm free flap was a workhorse flap for everywhere in intraoral defects. We had used the flap on cheek, floor of mouth, tongue without any significant complications. But the application of the flap was required for long operation time, which was disadvantageous to the old, weak patients. 4. Cervical platysmal flap could be easily applicable for buccal cheek, floor of mouth after excision of the cancer lesion. The design of the flap could be made simultaneously on neck dissection, but the danger of cancer remnants on the flap always might be remained. 5. Buccal fat pad pedicled flap must have been a primary flap for repair of oroantral fistula especially on posterior maxilla. The flap survival will be expected if the considerations for above reconstructive methods on site, size, condition of defects primarily could be made.

순 구개열(cleft lip and palate)은 구강악안면 영역에서 가장 빈번하게 발생하는 선천성 기형 중 하나로 유전적, 환경적 요인에 의해 발생된다. 순 구개열 환자는 입술, 코 등의 기형을 보이며 치과적 문제점으로, 이환측 측절치는 결손되어 있거나 과잉치가 존재하고 형태적 이상을 보이는 경우가 많고, 맹출하지 못하거나 이소맹출을 하게된다. 이른 시기에 수행된 수술의 반흔조직(scar tissue)으로 인하여 상악골 성장의 장애가 발생되어 흔히 골격성 III급 부정교합이 야기되기 쉬우며, 섭식장애와 발음장애를 보이기도 한다. 이러한 복잡한 문제로 인하여 여러 분야의 전문가들로부터 다양한 관리가 필요하다. 순/구개열(cleft lip and alveolus only)은 악안면 영역에 제한적으로 영향을 미친다. 비이환측은 전방으로 회전되어 수평피개가 증가되고, 이환측은 내측으로 회전되어 견치부에서 end to end 관계, 혹은 반대교합을 보인다. 순/구개열 수술은 이와 같은 문제점 등을 개선시키기 위한 것이며, 상악골의 전후방적 성장에는 큰 영향을 미치지 않는 것으로 보고되고 있다. 본 증례는 좌측에 순/구개열을 가진 5세 3개월의 여아로 생후 3개월 및 3세에 두 번의 구순열 봉합 수술을 받았으며, 상악 좌측 유측절치와 영구측절치가 결손되어 있었고, 다발성 우식증 및 비구누공(oroantral fistula)이 존재하였으며, 골격성 3급 부정교합을 보였다. 그러나 본 증례가 지니고 있는 골격성 III급 부정교합은 구순열 수술후의 반흔조직에 의한 것은 아닌 것으로 판단되었으며, 환자의 기능과 심미성을 회복하기 위하여 혼합치열기 동안 공간관리(space supervision) 및 악기능 장치 (functional regulator)를 이용한 골격성 부정교합을 치료하였으며, 영구치열기 동안 고정성 교정치료를 시행한 후 보철 치료를 시행하여 비구누공을 key and keyway attachment와 Konus crown을 이용한 가철성 obturator로 폐쇄하여 양호한 결과를 보였다.

During 42 month period 91 consecutive patient underwent coronary artery bypass surgery. The mean age of these patient was 57 years [range from 28 to 78 years . There were 57 men and 34 women. The preoperative risk factors that include beyond the 50 % of total patients were male sex, obesity, hypo-high-density lipoproteinemia, smoking, hypercholesterolemia, hyper-low-density lipoproteinemia, hypertriglyceridemia and hypertension. Preoperatively 27 patients had stable angina pectoris and 39 patients of unstable angina pectoris. Twenty five patients had previous myocardial infarction history. The patterns of disease were 8 patients of single vessel involvement, 18 patients of double vessel involvement, 54 patients of triple vessel involvement and 11 patients of left main coronary artery disease. Fifty five patients were in Canadian Cardiovascular Society functional class III. Myocardial revascularization was performed under emergency conditions in 5 patients. Nine percent of patients had previous PTCA history. We performed 16 cases of sequential anastomosis, internal mammary artery harvest in 86 percent of total patients and total 284 distal anastomoses[mean 3.1 anastomosis per patient . The mean ACC time was 60.5 minutes and ECC time was mean 110 minutes. The combined surgeries were 16 cases of endarterectomy, 2 cases of LV aneurysmectomy, 1 case of Bentall operation, 1 case of repair of sinus of Valsalva, 1 case of ligation of coronary AV fistula and 1 case of excision of breast mass. The most common complication was wound infection[12 cases, 13 % . There was one hospital death due to postoperative respiratory failure and low output syndrome in patient with postinfarction VSD, LV aneurysm. Postoperative 88 patients were in Functional class I or II. The 99mTc-MIBI myocardial perfusion scan that used as evaluation of postoperative state was well correlated with patient`s symptoms instead of some disadvantages.

Esophageal reconstruction was performed in 344 patients with irreversible stricture of the esophagus resulting from caustic burns at National Medical Center from 1959 to 1982.There were 113 males and 231 females, and ranging from 2.5 to 58 years of age, and mean age was 26.5 years, and 25 cases were less than 10 years old. Caustic materials were 286 [83.2%] alkali and 50[14.5%] acid. The most frequent stricture site was upper thoracic esophagus as 56.7%, and the next was cervical as 31.4%, and lower, 11.9%. The stomach was involved in 10.8% totally, and hypopharyngeal stricture was also noticed in 3.2%, and in 3 cases, hypopharyngeal reconstruction was needed due to extensive scar change. In 329 of total 344 cases, colon interposition was performed without resection of the strictured esophagus except 4 cases which were complicated T-E fistula or perforation, and most of them, about 10-15 cm of terminal ileum with right half of the colon was used as the graft. The left colon with anti-peristalsis was used as graft only in 30 cases. The most common postoperative complication was anastomotic leak as 16.7% of total cases, and it was 12.5% from neck, 3.3% from ileocolostoma and 0.9% from cologastrostoma. Next common complication was neck stenosis [8.8%], aspiration pneumonia [6.4%], and graft necrosis [3.9%] in order. Overall operative mortality was 5.5% [14/329], and main causes of death were graft necrosis, sepsis due to anastomotic leak, gastric bleeding, and intestinal obstruction. Besides of colon interposition, according to shape or level of the stricture, plastic repair or segmental resection and direct anastomosis was done in 9, and 1 of them were complicated stenosis at the anastomotic site. In lower stricture, esophagogastrostomy was done in 10 cases, and 1 case expired due to hepatitis, and anastomotic stenosis was occurred in 2 cases at 1.5 months and 2.4 years later. During follow-up of 298 cases colon interposition from 6 months to 22 years, 82.6% was excellent, and 2.9% was complained of mild discomfort, and 4 cases were dead laterly, but 3 of them were not related to reconstruction.

Iatrogenic vascular injury (IVI) can occur with any technique or type of surgery performed around a blood vessel. Patients with severe trauma are at risk of IVI. In this study, we describe our experiences of IVI in the trauma field. We reviewed five patients who were diagnosed with an IVI and received either surgical or endovascular treatment. Of the five patients, one had an arterial injury, three had venous injuries, and one had an arteriovenous fistula, a form of combined arterial and venous injuries. Of the five patients, four had undergone orthopedic surgery. The IVIs of three patients were immediately identified in the operating room and simultaneous vascular repair was performed. The remaining one patient underwent additional surgery for occlusion related to entrapment of the superficial femoral artery by a surgical wire used during orthopedic surgery. Complications presumably related to the IVI were identified in two patients. IVI in trauma patients can be successfully managed, but significant morbidity can occur. If an IVI is suspected, immediate evaluation and management are required.
