Pulmonary embolism is a one of the major cause of postoperative death. Surgery predisposes patients to pulmonary embolism, even as late as one month after the operation. The accurate detection of pulmonary embolism remains difficult, and the differential diagnosis is extensive. The prevention of pulmonary embolism is thus of paramount importance. We report a case of pulmonary embolism after coverage of pressure sore on the left ischium on the 8th day after operation. The patient was 60 years old, a severe smoker, in the high quantity of body mass index and had hypertension. The risk factors are 60 years of age or older who were in the highest quantity of body mass index. Heavy cigarette smoking and high blood pressure are also identified as risk factors. Plastic surgeons should keep the probability of pulmonary embolism development after operation in mind. When taking history, the risk factors should be checked certainly. The immobilization may explain the probability of pulmonary embolism development. Therefore absolute bed rest or positional maintenance should be avoided. Until recently, low molecular weight heparin has been used for preoperative prophylaxis. Plastic surgeons should be concerned in low molecular weight heparin for prophylaxis of the pulmonary embolism and study the indications and effectiveness in liposuction or abdominoplasty.

Although chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) have distinct clinical features, both diseases may coexist in a patient because they share similar risk factors such as smoking, male sex, and old age. Patients with both emphysema in upper lung fields and diffuse ILD are diagnosed with combined pulmonary fibrosis and emphysema (CPFE), which causes substantial clinical deterioration. Patients with CPFE have higher mortality compared with patients who have COPD alone, but results have been inconclusive compared with patients who have idiopathic pulmonary fibrosis (IPF). Poor prognostic factors for CPFE include exacerbation, lung cancer, and pulmonary hypertension. The presence of interstitial lung abnormalities, which may be an early or mild form of ILD, is notable among patients with COPD, and is associated with poor prognosis. Various theories have been proposed regarding the pathophysiology of CPFE. Biomarker analyses have implied that this pathophysiology may be more closely associated with IPF development, rather than COPD or emphysema. Patients with CPFE should be advised to quit smoking and undergo routine lung function tests, and pulmonary rehabilitation may be helpful. Various pharmacologic agents and surgical approaches may be beneficial in patients with CPFE, but further studies are needed.

Three hundred consecutive adult patients having cardioaortic surgery under the cardiopulmonary bypass for a variety of cardioaortic lesions were evaluated retrospectively for postoperative hyperbilirubinemia[above 5mg/100ml].We found twenty eight patients with postoperative hyperbilirubinemia and divided them into two groups according to the postoperative day of peak s-bilirubin .Group A was the patients with a peak s-bilirubin level within three days ,and group B above three days postoperatively.Group B was divided into group S[survive] and group D[death] . We had compaired the survival & death group and observed the correlation between the decreasing tendency of postoperative s-bilirubin & the nutrition per os in group B. The incidence of postoperative hyperbilirubinemia,as defined by a s-bilirubin concentration of 5.0mg/100ml or greater,was 9.3%.The mortality rates of group A & B were 0.0% and 35.7% respectively.Important contributing factors between group A & B were the age,duration of ICU,Max.DOAB[maximum dose of catecholamine used],amount of blood transfused during or shortly after surgery and preoperative pulmonary hypertension[main pulmonary artery pressure > 30mmHg] and backward heart failure. The risking factors of group D compared to group S were as follows the age,preoperative & postoperative SGOT[serum glutamic-oxaloacetic trasaminase],postoperative total & indirect bilirubin,cardiopulmonary bypass time,duration of ICU & mechanical ventilation ,Max.DOAB,preoperative pulmonary hypertension and backward heart failure.The six patients in group B showed good correlation between the decreasing point of s-bilirubin and the starting day of oral or tube feeding.

Respiratory syncytial virus (RSV) is a main cause of hospitalization for bronchiolitis and pneumonia in infants worldwide. Children with hemodynamically significant congenital heart disease (HS-CHD), as well as premature infants are at high risk for severe RSV diseases. Mortality rates for CHD patients hospitalized with RSV have been reported as about 24 times higher compared with those without RSV infection. Recently with advances in intensive care, mortality rates in CHD patients combined with RSV have decreased below 2%. The requirements of intensive care and mechanical ventilation for CHD patients with RSV infection were still higher than those without RSV infection or with non-CHD children. RSV infection has frequently threatened CHD infants with congestive heart failure, cyanosis, or with pulmonary hypertension. As a progressive RSV pneumonitis in those infants develops, the impairment of oxygen uptake, the breathing workload gradually increases and eventually causes to significant pulmonary hypertension, even after the operation. Preventing RSV infection as much as possible is very important, especially in infants with HS-CHD. A humanized monoclonal antibody, palivizumab, has effective in preventing severe RSV disease in high-risk infants, and progressive advances in supportive care including pulmonary vasodilator have dramatically decreased the mortality (<1%). Depending on the global trend, Korean Health Insurance guidelines have approved the use of palivizumab in children <1 year of age with HS-CHD since 2009. Korean data are collected for RSV prophylaxis in infants with CHD.

Objectives : Elastic fibers are found in the skin, lungs, arteries, veins and other structures. Elastases destroy the elastic fibers and cause the emphysema and pulmonary hypertension. Oxidative stress is needed for these pathologic changes. Accordingly, present study was designed to investigate the effect of Yukmigeehwang-hwan extracts (YHE) on elastase activity and anti-oxidative effects of YHE. Methods : The inhibitory effects on elastase and DPPH and NO free radical scavenging activities of YHE were measured. Results : The elastase activity was significantly inhibited by YHE. YHE significantly scavenged DPPH and NO free radicals as well. Conclusion : YHE showed the elastase-inhibiting effects and anti-oxidative activities in vitro. These results suggest that YHE may have potential roles in the treatment of pulmonary emphysema and pulmonary hypertension.

Recently, the arterial switch operation has received more interest and increased application for many patients with TGA [Transposition of the Great Arteries]. Not all patients, however, are suitable candidates for this approach, and its success will be measured against the Senning procedure. From June 1982 through June 1989, 48 consecutive patients underwent correction of TGA by a modification of the Senning procedure in our hospital. 34 were males and 14 females, with ages ranging from 3 months to 99 months [mean age 14 months]. The patients were divided into two groups, group I [TGA with intact ventricular septum or without significant pulmonary hypertension] and group II [TGA with significant pulmonary hypertension]. The hospital mortality was 9.5 % in group I and 55.6 % in group lI. 31 patients were discharged from the hospital after a Senning operation and have been followed a mean of 31.2 months. There were 5 late deaths, 3 in group I and 2 in group II. All patients were followed up with EKG, echocardiogram, and in several cases, Holter monitor and cardiac catheterization and angiography were also performed. There have been arrhythmias in 7, superior vena caval obstruction in 5, pulmonary venous obstruction in 2 and tricuspid insufficiency and/or right ventricular dysfunction in 16 patients. The Senning operation for Simple TGA can be performed with a low operative mortality and morbidity, but tricuspid insufficiency and/or depressed right ventricular function can be a problem with prolonged follow up.

Pulmonary embolism (PE) is a potentially fatal disease if the diagnosis or treatment is delayed. Currently, multidetector computed tomography (MDCT) is considered the standard imaging method for diagnosing PE. Dual-energy CT (DECT) has the advantages of MDCT and can provide functional information for patients with PE. The aim of this review is to present the potential clinical applications of DECT in PE, focusing on the diagnosis and risk stratification of PE.

신생아 폐고혈압 지속증은 치료가 힘들고 사망률이 높은 질환이나, 산화질소 흡입 치료가 시행된 이후 사망률의 많은 감소를 가져왔다. 그러나, 신생아 집중 치료실이 있는 병원이라도 이러한 산화질소 흡입 치료가 가능하지 않는 곳이 많고, 산화질소 투여에도 호전되지 않는 경우도 있다. 흡입 iloprost는 최근 원발성 혹은 이차성 폐고혈압 환자에서 사용이 늘고있는 폐동맥 확장제로, 신생아 폐고혈압 지속증에 사용한 증례가 외국에 보고된 바 있다. 환아는 출생시 심한 태변 착색과 출산 질식, 진행되는 저산소증을 보였으며, 신생아 폐고혈압 지속증으로 진단되었다. 환아는 지속적인 저산소증을 보였으며, 통상적인 지지 치료에도 호전되지 않았다. 당시 저자들의 병원에는 산화질소 흡입 치료가 가능하지 않아, iloprost 흡입 치료를 시도하였다. Iloprost 흡입 치료 이후 수시간 내에 산소 포화도가 증가하였으며, 심초음파상에는 동맥관을 통한 우좌 단락이 좌우로 바뀌었고, 우심실 압력이 감소하였다. Iloprost 흡입 치료를 하는 동안 특별한 부작용은 관찰되지 않았다. 저자들은 산화질소 흡입치료가 가능하지 않은 상황에서 신생아 폐고혈압 지속증 신생아의 치료로 iloprost 흡입 치료를 시도한 경험을 보고하는 바이다.

8개월령 암컷 포메라니안 개가 심잡음과 심비대를 주호소로 내원하였다. 검사결과 좌-우단락 동맥관 개존증과 중등도의 심부전 (ISACHC II) 으로 진단되었다. 잔존 동맥관은 우측 대퇴동맥을 통한 $5mm{\times}3loops$ 코일 색전술을 통해 성공적으로 치료되었다. 2개월 후 환축은 현저한 저혈압과 심한 설사, 흉수가 차는 증상으로 다시 내원하였다. 검사 결과 심각한 폐성고혈압과 삼첨판 역류가 발견되었다. Sildenafil (3 mg/kg, PO, TID) 을 투여함으로써 임상증상은 조절되었으나, 코일빠짐과 보호자의 부적절한 투약으로 인해 환축은 폐사하였다. 부검 결과 폐성고혈압의 원인은 비정상적인 위치로 빠진 색전 코일에 의한 것으로 밝혀졌다. 토이 품종에서 PDA의 치료를 위해 색전 코일이 널리 사용되고 있지만, 장착된 코일이 빠질 위험을 줄이기 위해서는 PDA의 크기와 형태에 대한 한층 더 세심한 평가가 필요하다.
