목 적 : 저자들은 RDS 환아의 임상 경과 중에서 PDA가 동반되는 군과 동반되지 않은 군을 비교하여, 이들의 주산기 병력의 특성, 임상 양상과 경과를 비교 관찰하여 두 군 사이에 차이점이 있는지를 검토함으로서, 향후 RDS 환아의 관리에서 PDA 동반에 따른 효율적인 관리의 정보를 얻기 위하여 본 연구를 실시하였다. 방 법 : 2000년 1월부터 2002년 12월까지 경희대학교병원 신생아 집중치료실에서 신생아 RDS로 진단되어 치료한 총 83례를 대상으로 하였다. 총 83례 중에서 PDA를 동반한 군(A군)은 17례, PDA를 동반하지 않은 군(B군)은 66례였다. PDA는 울혈성 심부전의 임상증상을 보이거나, 청진상 심잡음이 들리며, 방사선 소견상에서 폐부종이 심해지거나 CT ratio가 증가되는 경우에 심초음파를 하여 진단하였다. 후향적 방법으로 증례들의 임상 기록지를 검토하여, 두 군 사이의 임상적 양상과 경과의 차이점을 분석하였다. 결 과: A군에서 B군에 비해 재태기간이 짧고 출생 체중이 낮아 미숙의 정도가 심할수록 PDA의 발생 빈도가 높았다. 주산기 가사의 빈도는 A군에서 의미있게 높았다. 만성 폐질환, 뇌실 내출혈, 괴사성 장염, 미숙아 망막증, 구루병, 패혈증, 담즙성 황달의 빈도가 B군에 비하여 A군에서 높았다. 결 론 : 두 군의 주산기 병력의 특성은 유의한 차이를 보임을 알 수 있었고 만성 폐질환 등의 합병증의 발생이 유의한 차이를 보였으나 후자의 경우 재태기간을 포함한 여러 인자를 고려하여야 하므로 앞으로 더 많은 연구가 이루어져야 한다고 사료된다.

Background: Treatment for patent ductus arteriosus (PDA) in premature infants can consist of medical or surgical approaches. The appropriate therapeutic regimen remains contentious. This study evaluated the role of surgery in improving the survival of premature neonates weighing less than 1,500 g with PDA. Materials and Methods: From January 2008 to June 2011, 68 patients weighing less than 1,500 g with PDA were enrolled. The patients were divided into three groups: a group managed only by medical treatment (group I), a group requiring surgery after medical treatment (group II), and a group requiring primary surgical treatment (group III). Results: The rate of conversion to surgical methods due to failed medical treatment was 67.6% (25/37) in the patients with large PDA (${\geq}2$ mm in diameter). The number of patients who could be managed with medical treatment was nine which was only 20.5% (9/44) of the patients with large PDA. There was no surgery-related mortality. Group III displayed a statistically significantly low rate of development of bronchopulmonary dysplasia (BPD) (p=0.008). The mechanical ventilation time was significantly longer in group II (p=0.002). Conclusion: Medical treatment has a high failure rate in infants weighing less than 1,500 g with PDA exceeding 2.0 mm. Surgical closure following medical treatment requires a longer mechanical ventilation time and increases the incidence of BPD. Primary surgical closure of PDA exceeding 2.0 mm in the infants weighing less than 1,500 g should be considered to reduce mortality and long-term morbidity events including BPD.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary leaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 UR.), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasohographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

From April, 1984 to August, 1986, 214 cases of cardiovascular surgeries had been performed at Yeungnam University Hospital consisting 158 open heart surgeries and 56 non-open heart surgeries. The leading cardiac anomaly of open heart surgeries was ventricular septal defect which was 43% of congenital heart diseases, and most of remaining non-open heart surgeries were ligating patent ductus arteriosus. We had observed 33 postoperative complications such as wound problems, transient arrhythmia, postpericardiotomy syndrome, bleeding requiring reoperation and so on. 3 cases of surgical mortality were present [2 in congenital heart diseases and 1 in acquired heart disease], which resulting 1.9% of surgical mortality rate in the open heart surgeries.

A clinical study was performed on 69 cases of isolated PDA surgically treated at the Department of Thoracic and Cardiovascular surgery of Kyung-Hee University Hospital from Mar. 1986 to Feb. 1994. Retrospective clinical analysis of these patients were as follows: 1.23 males and 46 females ranged in age from 16 days to 49 years. [mean 8.69yrs.,sex ratio M:F=1:2 2. Chief complaints were frequent URI in 44%, dyspnea on exertion in 16%,palpitation in 8%, easy fatigability in 6%, and no subjective symptoms in 26%. 3. On auscultation, typical continuous machinery murmur heard in 84%, and systolic murmur in 16% on Lt 2nd or 3rd intercostal space. 4. Simple chest x- ray showed increased pulmonary vascularity in 67%, cardiomegaly in 61%,and within normal limit in 16%. 5. EKG findings were LVH in 42%, biventricular hypertrophy in 17%, RVH in 3%, and within normal limit in 38%. 6. Echocardiogram was performed from all patient, and direct visualization of ductus in 93% 7. Cardiac catheterization was performed in 39 patients. The mean value of the results were;Differance SaO2[MPA-RV =11.03$\pm$ 5.26%,Qp/Qs=2.44$\pm$1.35,systolic pulmonary arterial pressure=40.69 $\pm$ 17.69mmHg. 8. 66 patients were operated through the left posterolateral thoracoctomy ; closure of ductus by double ligation in 43 cases, triple ligation in 23 cases.3 patients were operated by simple closure under cardiopulmonary bypass. 9. There was no death associated with the operation. The operative complications were atelectasis in 8 cases, pneumonia in 4 cases recannalization in 2 cases, and hoarseness in one case. 10. Systemic diastolic pressure was increased 8.12$\pm$ 0.13mmHg, and pulse pressure was decreased about 9.52 $\pm$ 1.87mmHg.

목 적 : 경피적 동맥관 폐쇄술은 동맥관 개존증의 표준 치료로 시행되고 있다. 저자들은 동맥관의 최소 직경(MD)과 체혈류와 폐혈류의 비(Qp/Qs ratio)를 기준으로 하여 선택한 각각의 기구들로 경피적 동맥관 폐쇄술 시행한 후 추적 관찰 결과를 비교, 분석하여 새로운 기구 선택 기준의 효용성과 안전성을 알아보았다. 방 법 : 2003년 2월부터 2006년 1월까지 본원에서 동맥관 개존증을 진단받고 동맥관의 크기 및 Qp/Qs 비에 따라 CDC, PNO, ADO를 선택하여 경피적 동맥관 폐쇄술을 시행받은 138명의 환자를 대상으로 하였다. 그리고 2000년 2월부터 2003년 1월까지 본원에서 DO, PNO로 경피적 동맥관 폐쇄술을 시행받은 89명의 환자들을 대조군으로 설정하였다. 시술 전 환자의 임상적, 혈역학적 지표들을 확인하였고 시술 후 1일, 1개월, 6개월, 12개월, 그리고 12개월 이후 잔류 단락 유무 및 합병증을 평가, 비교하였다. 결 과 : 대상군 138명 모두에서 시술에 성공하였고 기구 색전도 없었으며 시술 후 12개월 이후 잔류 단락이 남아있지 않았다. 주요 합병증의 빈도는 대상군 138명 중 0명(0%), 대조군 89명 중 7명(7.9%)이었고(P<0.05) 전체 합병증의 빈도도 대상군 138명 중 2명(1.4%), 대조군 89명 중 8명(9.0%)으로(P=0.001) 대상군에서 대조군에 비하여 의미 있게 합병증의 빈도가 낮았다. 결 론 : 과거에 경피적 폐쇄가 어려웠던 큰 크기의 동맥관 개존에 ADO를 사용하게 되고 이전 기구들의 단점들이 개선된 최근 기구들을 각각의 특성에 적합하게 전략적으로 선택하여 시술함으로써 경피적 동맥관 폐쇄술의 결과가 향상되었고 더욱 안전하고 완전한 효과를 나타내게 되었다.

Pulmonary perfusion scan with radioactive $^{113m}In$-iron hydroxide particle was performed in the 25 cases of heart disease which had been diagnosed by cardiac catheterization prior to surgery from July, 1972 to July, 1973 at the Department of Radiology and Nuclear Medicine, Yonsei Medical College. It consists of 7 mitral stenosis, 2 mitral insufficiency, 1 aortic insufficiency, 3 atrial septal defect, 5 ventricular septal defect, 2 patent ductus arteriosus, 1 transposition of great vessel and 4 Tetralogy of Fallot. Findings of pulmonary perfusion scan in relation to hemodynamic data of cardiac catheterization were examined. 1) Out of 10 cases of acquired valvular heart disease, In 6 cases of mitral stenosis and 1 case of aortic insufficiency, radioactivity was increased at both upper lung. This finding is noted when pulmonary wedge or venous pressure was elevated above 22 mmHg and arterial systolic pressure above 33 mmHg. 2) Out of 15 cases of congenital heart disease. In almost all cases of atrial septal defect and ventricular septal defect except 2 cases, radioactivity was even at both entire lung. In 2 cases of patent ductus arteriosus, radioactivity was decreased especially at the left lung. It is observed that in acyanotic congenital heart disease, radioactivity of lung is not related with pulmonary arterial pressure. In 3 cases of Tetralogy of Fallot, radioactivity was even at both entire lung and in 2 of them, extrapulmonary radioactivity of liver or kidney which depends on size of defect and volume of right to left shunt reversible, was noted.
