나국주,김병표,홍성범,최용선,김상형,안병희 대한흉부외과학회 2005 Journal of Chest Surgery (J Chest Surg) Vol.38 No.1

A bronchopleural fistula after pulmonary resection is still showing high mortality and morbidity despite of advancing of treatment. Several treatment options have been developed including surgical treatment. In 1990, endobronchial closure using vascular occluding coils was introduced. These coils can occlude a bronchial air-leakage by mechanical obstruction as well as inducing fibrosis. We report, herein, the experience using a vascular occluding coils in treating postoperative bronchopleural fistula. 폐 절제술 후의 기관지 늑막루는 지금까지 치료법이 발달하였음에도 불구하고 높은 치명률을 보인다. 수술적 치료를 포함하여 많은 치료법이 발전하였는데 1990년 코일을 이용하여 기관지를 막는 방법이 소개되었다. 이 코일은 물리적인 폐쇄와 섬유화를 유발하여 기관지의 공기 누출을 막을 수 있다. 최근 수술 후 발생한 기관지 늑막루에서 코일을 이용한 치료법을 경험하였기에 보고하고자 한다.

From August, 1986 to December, 1993, mitral valve replacement was performed in 178 patients. Of the valve implanted, 114 were St.Jude Medical, 47 Duromedics, 16 Carpenter-Edward and 1 Ionesc-Shiley. The hospital mortality rate was 2.8%[5 patients and the late mortality rate was 7.5%[13 patients . The causes of hospital death were LV rupture in 1, renal failure in 1, cardiac tamponade in 1, valve malfunction in 1 and hypoxic brain damage in 1. The causes of late death were sudden death in 6, congestive heart failure in 4, brain ischemic injury in 3. Follow-up was done on 155 surviving patients : mean follow-up period was 50.94$\pm$8.04 months. The actual survival rate was 88.2% at 8 years. We concluded, therefore, that good clinical results could be achieved with mitral valve replacement in mid-term follow-up, and long-term follow-up is also necessary.

나국주,김광휴,안병희,김상형,Na, Guk-Ju,Kim, Gwang-Hyu,An, Byeong-Hui,Kim, Sang-Hyeong 대한흉부심장혈관외과학회 1996 Journal of Chest Surgery (J Chest Surg) Vol.29 No.3

Rupture of the main bronchus due to blunt chest trauma is very rare, especially In childhood although the incidence is increasing. Early diagnosis and primary repair not. only restore normal lung function but also avoid the difficulties and complications associated with delayed diagnosis and repair. We experienced 2 cases of right main bronchial rupture caused by traffic accidents. Patients suffered from progressively developing dyspnea and subcutaneous emphysema on the neck, anteriorchest,andanteriorabdominalwall. Emergency operations were performed through right posterolateral thoracotomy incision at the 4th intercostal space. Intraoperatively, the right main bronchus completely transsected and separated. Corrective bronchoplasty was performed with end-to-end anastomosis using interrupted suture with 3-0 Vicryle and the suture line was reinforced with azygos vein and parietal pleural flap. Postoperative courses were uneventful and patients discharged without any specific pro lems.

흰쥐의 적출 작업성 심장에서 허혈성 심정지시 Fructose-1.6-diphosphate(FDP)의 심근보호 작용

나국주 대한흉부심장혈관외과학회 1990 Journal of Chest Surgery (J Chest Surg) Vol.23 No.4

Currently numerous methods are in use for myocardial protection from the ravages of ischemia and hypoxia. This study was designed to compare with FDP-GIK[Group II, n=8] and GIK cardioplegic solution[Group I, n=8] in ability of myocardial protection and was examined in the isolated working rat heart subjected to long period[120 min] of hypothermic[10 - 15K] ischemic arrest with multidose[every 30 min] cardioplegic infusion. During postischemic reperfusion period 20 min, hemodynamic functions[aortic flow, coronary flow, peak aortic pressure, cardiac output, heart rate], biochemical enzymatic & electrical activities were evaluated. The time from onset of reperfusion to the return of regular sinus rhythm was significantly reduced from 87$\pm$3 sec to 17$\pm$2 sec[P<0.05]. The postischemic recovery of aortic flow was better in the group II [95.1$\pm$3.3% of its preischemic control level] than in the Group I [75.4$\pm$6.8%] [P<0.05]. Cardiac output and stroke volume was also better in the group[91.3$\pm$1.6%, 89.4$\pm$2.6%, respectively] than in the Group I [79.1$\pm$3.7%, 77.0$\pm$4.8%, respectively] [P<0. 05]. Creatine kinase leakage was also significantly reduced from 33.8$\pm$4.9 IU /10 min / gm * dry weight to 15.4$\pm$3.6 IU /10 min /gm * dry weight[P<0.05]. It is suggested that adding FDP to GIK cardioplegic solution improves its ability to protect the heart against long period of hypoxic ischemia.

전남대학교병원 흉부외과학교실에서는 1986년 8월 부터 1995년 7월 까지 65례의 대동맥판치환술을 경험하였다. 48명이 남자였고 17명의 환자가 여자였으며 19세에서 68세의 연령분포를 보였다. 판막질환의 원인은 류마티성 질환이 29례 (44.6%), 선천성 판막질환이 6례 (6.2%), 심내막염이 6례 (6.2%) 등을 보였다 동반된 수술은 10례에서 있었는데 5례가 선천성 심장 질환의 교정술이었고심막절제술 1례, 관상동맥우회로 조성술 1례, 발살바 동맥동 수술 2례, 대동맥 판막하막 절제술이 1례 등이었다. 사용된 판막은 St. Jude-Medical판이 42개, Duromedics판막이 22개, Bjork-Shiley판막이 2개, Carpentier-Edward판막 이 1개 있었다. 병원내 사망은 3례(4.6%)있었고 만기사망이 2례(3.2%)있었다. 수술후 사망례를 제외하고 100%의 환자에서 추적 관리가 되었고 10년 생존율은 85.3%를 보였다. 술후 합병증은 저심박출증이 8례, 부정맥이 5례, 기계판막과 관련된 용혈이 1례 있었다. 수술후NYHA기능분류는 수술전 2.79$\pm$ 0.66에서 수술후 1.25 $\pm$ 0.49로 개선되었고 단기 및 중장기 추적 조사 결과 우수한 기계판의 혈역학적 동태를 보였고 혈전증의 발생율은 아주 낮았다. From August 1986 until June 1995, single aortic valve replacement was performed in 65 patients at the Chonnam National University Hospital. worthy-eight were male and 17 were female patients, ranging from 19 to 68 years of age(median : 43 years). The causes of the valve lesions were rheumatic in 29 patients (44.6%), bicuspid aortic valve in 6 patients (6.2%), endocarditis in 6 patients(6.2%), unknown in others. Concomitant surgical procedures were performed in 10 patients : repair of congenital defect in 5, pericardiectomy in 1, coronary artery bypass grafting in 1, noncoronary sinus plication in 1, Valsalva sinus aneurysmectomy in 1, subaortic membrane resection in 1 Used valves were 51. Jude-Medical valve in 42, Duromedics valve in 22, Bjork-Shiley valve in 2, Carpentier-Edward valve in 1. There were 3 hospital deaths (4.6%), and 2 late deaths (3.2%). Follow-up was 95.2% complete. The 10-year acturlal survival rate was 85.3%. Postoperative complications were low cardiac utput in 8, arrythmia in 5, valve related hemolysis in 1, cerebral infarction in 1, and gastrointestinal bleeding in 2. Reoperation was performed in 4 for surgical bleeding, in 3 for paravalvular leak. The mean improvement in New York Heart Association functional class is from 2.79 $\pm$ 0.66 preoperatively to 1.25 $\pm$ 0.49 postoperatively(p < 0.001) The change of cardiothoracic ratio from preoperative to postoperative is 0.57 $\pm$ 0.06 to 0.54 $\pm$ 0.05 (p < 0.05). The left ventricular ejection fraction change is not significant perioperatively. There are no mechanical failures. This early and intermediate-term follow-up suggests that in adults in whom valve repair is not possible, the mechanical valve is a reliable and durable prosthesis with good hemodynamic function and a low rate of thromboembolic event.

The prevalence of gastroesophageal reflux disease(GERD) has been increased recently in Korea. Most patients who have GERD are well treated by medication. But patients who have suboptimal disease control under medical therapy are needed further treatment. Nowadays minimally invasive surgery using laparoscopy and thoracoscopy has become popular in the operation of GERD although antireflux surgery is vary. Antireflux surgery is a well-documented, effective therapeutic alternative to control GERD.

심장 점액종의 임상적 고찰

나국주 대한흉부심장혈관외과학회 1990 Journal of Chest Surgery (J Chest Surg) Vol.23 No.6

From 1981 to 1990, we performed operation on 6 patients with cardiac myxomas, which were located in the left atrium in 5, in the biatrium in 1. There were 3 male and 3 female patients ranging in age from 13 years to 69 years. Symptoms included exertional dyspnea, palpitation and signs of systemic illness. Diagnosis was accomplished by angiography[3 patients] and echocardiography [3 patients]. In all cases, myxomas were excised successfully through incision of interatrial septum There were no operative deaths or intraoperative embolic episode. Follow-up has been 40.0\ulcorner40.6 months[ranging from 1 month to 9 years], results of each patient were excellent We suggested that excision of intracardiac myxomas is curative and follow-up results are excellent. The transseptal approach provides adequate exposure and allows complete removal of the tumor regardless of its location.

염증성 근섬유 아세포종은 주로 어린이와 젊은 성인에서 발생하는 고형 종양으로, 고립성 폐 결절의 약 0.7%를 차지한다. 1937년 처음으로 폐에서 발생한 예가 보고된 이후 장간막(mesentery)이나 심장 식도 부위(cardioesophageal region)에 발생한 것들이 보고되고 있다. 이것은 조직학적으로는 양성이지만 국소 침습성과 재발성 때문에 악성을 완전히 배제하기 어렵다. 최근 본 병원에서 좌측 폐에 발생한 염증성 근섬유 아세포종을 수술적 절제 후 재발 소견 없이 추적 관찰 중이다. Inflammatory myofibroblastoma is a solid tumor, occurring mainly to children and young adults, and occupying 0.7% of total isolated pulmonary nodules. Since 1973, several cases about inflammatory myofibroblastoma have been reported. Firstly, this tumor was found in lungs. Then, tumors have been founded and reported in mesentery or cardioesophageal region. Histologically, this tumor can be classified as a benign tumor. However, since this tumor has two characteristics showing malignancy, that is, local invasion and recurrence, malignancy can not be completely excluded. Recently, a patient with pulmonary inflammatory myofibroblastoma underwent surgical resection without any signs or symptoms of recurrence.
