상완골 근위부 골절의 치료를 위해서 실시하는 상완골 두 치환술은 고난도의 수술이다. 그러나 수술 수기에 만전을 기하고 골절을 위해서 특별하게 고안된 치환물을 사용하면 통증을 해소되는 것은 물론이며 대부분의 견관절 기능도 회복이 가능하다고 생각한다. 또한 보다 좋은 결과를 얻기 위해서는 치환물과 수술 수기 등에 대해서 지속적인 개선이 매우 중요하다고 생각한다.

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.

Background. Infective endocarditis s an uncommon but serious disease in children. Optimal treatment strategy, especially surgical indications, continues to evolve. Method. In this report, we retrospectively reviewed 19 patients who underwent operations in Seoul National University Children's Hospital for infective endocarditis between September 1986 and February 1996. There were 8 male and 11 female patients(mean age 70.6 months) and their main symptoms were fever and dyspnea. Preoperative echocardiography detected vegetation in 14 cases out of 19. Congenital anomalies were in 15 cases and acquired forms were in 4 cases. Causative organisms were identified in 12 cases and Gram-positive cocci were in 7 cases. Adequate preoperative antibiotic management was done. Result. With cardiopulmonary bypass in all cases, surgical corrections including vegetation removal were performed. 4 patients died after operations(21.1%). All the mortality cases were having underlying complex cardiac anomalies. There were no late deaths. Act arial survival rate was 79.0% at 1 year and 79.0% at 5 year and reoperationfree survival rate was 73.7% at 1 year and 73.7% at 5 year. Collclusion. Despite advances in antibiotic therapy, early surgical treatment is imperative in a significant subset, and concurrent intracardiac repair should be appropriate.

Purpose: This study evaluated the preoperative and postoperative radiologic findings of patients with complete repairs after massive rotator cuff tears along with the incidence of re-tear and the clinical outcomes. Materials and methods: This study evaluated 33 cases who had open complete repairs for massive rotator cuff tears and these patients were followed up for more than 24 months. The clinical evaluation was performed according to the shoulder joint function test of the American Shoulder and Elbow Surgeons (ASES), and the degree of arthritis related to the massive rotator cuff tears was evaluated using the Hamada classification. Results: The ASES scores improved from 37.6 preoperatively to 85.6 postoperatively. The mean preoperative acromio-humeral interval (AHI) score was 6.5 mm, which increased to 9.3 mm immediately after surgery, and there was a decreased to 6.5 mm noted at the last follow up. The lower radiology stages of arthritis according to the classification showed better preoperative and postoperative results. Conclusion: An open complete repair as the surgical treatment for a massive rotator cuff tear showed satisfactory results for pain relief and an improvement in the shoulder joint function though re-tear after surgery.

배경 및 목적: Stand A형 급성대동맥박리증의 박리 시발점이 수술치환부위 내에 있는 경우와 그렇지 않은 경우의 임상적 차이점을 분석하여 치료에 도움을 주고자 하였다. 방법: 1991년 3월부터 1999년 7월까지 본원에서 급성상행대동맥박리증으로 진단되어 상행대동맥치환술을 받은 40명의 환자를 대상으로 병력기록을 근거로 수술 소견 상 찢어진 부위를 발견한 환자 27명을 1군, 발견 못한 나머지 13명을 2군으로 나누고 환자의 술 전 상태와 수술소견 및 술후 경과의 임상적 차이점을 분석하였다. 결과: 1군에서 술전에 저혈압, 대동맥판막부전, 심허혈, 신부전 등이 더 많이 발생되었다. 수술 소견 상 대동맥근부 이상은 1군에서 많았다. 가성 내강 내 혈종은 2군에서 더 많이 관찰되었지만 통계적으로 유의하지는 않았다. 술후에 2군에서는 신부전이 더 많이 발생하였고 술후 출혈로 인한 재수술은 1군에서 더 많았다. 조기 수술사망은 1군에 6명으로 사망률은 22.2%이었고 2군에는 사망 례는 없었다. 결론: 본 연구를 통하여 상행대동맥에서 내막 파열이 발견된 1군에서는 2군에 비해 술전 상태가 불량하였고 대동맥판막 병변으로 수술이 복잡해져 사망률이 높다고 생각된다. 반면 원위부 하행대동맥에서 박리가 진행되어 상행대동맥으로 이어진 2군에서는 1군에 비해 순환 장애로 인해 술후에 신부전이 더 많이 발생되었다. 결론적으로 상행대동맥내막에 파열점이 없었던 군에서 수술 예후는 상행대동맥내막에 파열점이 있는 군보다 더 좋았다.

Infected aortic aneurysms are rare, but the mortality of patients with infected aortic aneurysms remains high. Open surgical procedures are the standard of care for infected aneurysms of aorta, but the surgical results are often disappointing. The risk factors related to the high mortality include aneurysm rupture and a suprarenal aneurysm location. The classic method for treating infected aneurysms has been aneurysm resection, soft tissue debridement, remote arterial reconstruction out of the field of infection and antibiotics. Infected anuerysms located in the suprarenal aorta are highly lethal because of the need to reimplant the visceral or renal arteries and the graft related complications. We reported here on a case of suprarenal infected aortic aneurysm in a 55-years-old man. We also include a review of the relevant medical literature.

Background: The author studied to define the current indications for surgical management of chest tuberculosis and to analyze the results of the operative procedures. Material and Method: The records of 87 patients among 107 patients operated on between January 1992 and May 1995 were reviewed. These patients were divided into 4 groups. Group I patients (n=45) underwent decortication with or without wedge resection of the lesion. Group II patients(n=23) underwent radical curettages of chest wall involving rib caries with or without thoracotomy. Group III patients(n=12) underwent standard pneumonectomy or pleuropneumonectomy. Group IV patients(n=7) underwent exploratory thoracotomy or wedge resection of tuberculous lung lesion. Result: Statistical analysis revealed an inverse correlation between AIs and intratumoral microvessel densities in squamous cell lung carcinoma(Spearman rank correlation coefficient r=- 0.229, p=0.047). Conclusion: The author concludes that surgery for chest tuberculosis is the definite management for therapeutic indications and surgical radication of tuberculous carriers for management of chest tuberculosis is safe and has satisfactory results.

Surgical resection is the most effective treatment in operable lung cancers. However, less invasive local treatments are being applicated to the patients having high surgical risk due to their poor general condition. Cryosurgery is known to be highly effective and safe in the treatment of liver and prostate cancers and it is also being applicated in the treatment of lung cancers, especially with the excision of tracheal mass and lung parenchymal cancers. In our hospital, we have tried a less Invasive method, the cryotherapy, to a patient who had a newly developed lung cancer at his right lower lobe after he had been treated with right upper lobe resection and left upper lobe resection due to bilateral lung cancels. After the treatment, he is being followed up at our out patient department for 2 years. Here, we present the method and result that have been applicated in this case.

흉선종은 비교적 드문 종양으로 알려져 있다. 예후를 알 수 있는 가장 중요한 인자는 수술시 육안적인 종양의 침윤정도이며, 치료는 수술에 의한 종양의 제거가 무엇보다 중요하고, 방사선 치료 역시 수출 후 국소적 계발의 방지를 위해 쓰이고 있다. 근치적 목적의 방사선 치료도 수술이 어려운 경우에 시행되고 있는 형편이다. 저자들은 1977년 1월부터 1984년 12월까지 세브란스병원 연세암센타 치료방사선과에서 흉선종 진단받고 치료한 14명의 환자를 후향성 분석에 의해 다음과 같은 결과를 얻었다. 1. 6명의 환자$(14\%)$가 근무력증을 나타냈다. 2. 주변조직의 침윤이 $86\%(12/14)$에서 관찰되었다. 3. $43\%$에서 육안적 완전 절제를 시행하였고 $14\%$에서 부분결제, 그리고 $43\%$에서는 생검만 시행 하였다. 4. 수술 후 혹은 근치적 목적의 방사선치료는 8명의 환자에서 시행하였으며 그중 현재 5명은 생존(4년, 2.8년, 1.6년, 1.4년, 1.3년), 3명은 사망(1년, 0.6년, 0.6년)하였다. 5. 방사선 치료선량은 대체료 $4,000\~4,500rad(1950\~7,000rad)$를 전후 흉곽 부위에 외부 조사하였다.

From 1970 to 1982, thirty one patients with malignant tumors of the parotid gland were treated with radiation therapy at department of Radiation Oncology, Yonsei University College of Medicine, Yonsei Cancer Center. Indication for radiotherapy were as follows: 1) when there were microscopic or gross residual diseases (6 patients), 2) when the patients considered to have high risk factors (15 patients), 3) when the tumor found to be inoperable (6 patients), 4) when there was recurrence after surgery (4 patients). Most patients were treated with a total of 5,000 to 6,500cGy in 5 to 6 weeks except when there were gross diseases, in which patients received slightly higher dose up to 7,000 cGy in 7 weeks. Locoregional failure rate was $43\%$ in patients with microscopic or gross residual disease and high risk factors (postoperative radiotherapy group) and 20 in patients with inoperable tumor and recurrence after surgery (Primary radiotherapy group). There was no difference in the failure rates amen!1 the various histological types. Eight patients failed distantly, Severe complications appeared only in 2 patients irradiated for inoperable advanced diseases.
