Total anomalous pulmonary venous return (TAPVR) is very rare congenital heart disease. 25-year old male was admitted our hospital with dyspnea, headache and syncope as chief complaint. He was confirmed as mixed type TAPVR by echocardiography and cardiac catheterization. In this case, mixed type TAPVR was consisted with supracardiac type connection of left pulmonary vein and cardiac type of right pulmonary vein. Supracardiac type of left pulmonary common channel was anastomosed to the left auricular appendage during total cardiopulmonary bypass with fibrillating heart. Cardiac type of right pulmonary vein was operated during moderate hypothermia and aortic cross clamping. Coronary sinus septum was incised into ASD and closed with Gore-Tex patch so that right pulmonary blood flow directed to the left atrium. The patient's post-operative course was uneventful.

Pulmonary arteriovenous malformation(PAVM) is an uncommon congenital anomaly. As pulmonary arteriovenous malformation is a direct communication between the branches of pulmonary artery and vein which originated from the malformation of capillary development, major disturbances in gas exchange can result. This malformation results in the several symptoms such as dyspnea, hemopyssis, cyanosis, and severe neurologic complaints. However, the most of patients are usually asymptomatic. Selective pulmonary angiography is well known the helpful diagnostic method. Recently, therapeutic embolization has been advocated as the treatment of choice for pulmonary arteriovenous malformations. We report a case of multiple pulmonary arteriovenous malformation, which was detected on the simple chest X-ray and successfully treated with coil embolization in a 19-year-old asymptomatic woman.

Four neonates with critical pulmonary outflow obstruction underwent emergency palliative operation between February 1988 and May 1989 at the department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. There were three boys and one girl, the mean age was 12.25 days [ranging from 3 days to 26 days], and the mean body weight was 3,625 gm [ranging from 3,450 gm to 4,200 gm]. Two patients had severe pulmonic valvular stenosis with intact ventricular septum, a third had pulmonary atresia with intact ventricular septum, and another had pulmonary atresia with ventricular septal defect. All were cyanotic, showed arterial desaturation with metabolic acidosis, and had congestive heart failure. To relieve the pulmonary outflow tract obstruction, we performed transventricular pulmonary valvulotomy [Brock operation] with a mosquito clamp in all cases without extracorporeal circulation. Three patients survived the operation and showed satisfactory postoperative results. The patient who had pulmonary atresia with ventricular septal defect expired 5 days after surgery. We consider transventricular pulmonary valvulotomy [Brock operation] with a mosquito clamp as one of the preferable procedures for critical pulmonary outflow obstruction in the neonatal period.

Primary intracardiac repair of tetralogy of Fallot with low mortality and early good results, has been accomplished in recent years. But palliative procedures have been reserved for those hypoplastic pulmonary arteries, a hypoplastic left ventricle or anomalies of the coronary artery would make total correction difficult. And the Blalock-Taussig shunt operation is recognized as a standard and popular palliative procedure. I undertook a retrospective determination of the effect of the Blalock-Taussig shunt operation on the development of the main pulmonary artery and the right and left pulmonary arteries. Between January, 1980, and April, 1987, at the Severance Hospital, 16 patients were studied by cardiac catheterization and angiocardiography, before undergoing Blalock-Taussig shunting procedures for the palliation of severe symptoms of tetralogy of Fallot, and some time later, usually prior to a second procedure. The mean interval between catheterizations was 22.25 months. Patients with tetralogy of Fallot and pulmonary atresia or with an occluded shunt were not included. The primary and secondary angiograms of each patient were reviewed, and measurements of the diameter of the main pulmonary artery, the right and left pulmonary arteries, and the descending thoracic aorta were taken. The results are as follows; 1. The hematocrit decreased from 56.39% to 50.34%[p< 0.05], and the arterial oxygen saturation increased from 62.00 % to 81.31 %[p< 0.001] following shunt procedures 2. The ratio of the diameter of the right pulmonary artery plus the left pulmonary artery to the diameter of the descending thoracic aorta increased 1.30 k 0.28 times [p< 0.01]; but the ratio of the diameter of the main pulmonary artery to the diameter of the descending thoracic aorta increased 1.10 * 0.33 times, which was not. significant[p< 0.05]. 3. The interval between shunting and second catheterization was not related to the magnitude of change in the pulmonary arteries[r=0.141, p >0.05]. 4. The changes in the ratio of the diameter of the right pulmonary artery plus the diameter of the left pulmonary artery to the diameter of the descending thoracic aorta was inversely related to the initial ratio[r=0.757, p >0.001], but the change in the ratio of the diameter of the main pulmonary artery to the descending thoracic aorta was not related[r=0.059, p >0.05]. 5. There were no differences in enlargement of the pulmonary artery on the side of the shunt [ipsilateral] versus enlargement on the opposite side [p >0.05], nor according to the size of the shunt[p >0.05]. In conclusion, this study suggests that the Blalock-Taussig shunt is effective for the development of the right and left pulmonary arteries but not effective for the main pulmonary artery.

Background: When we define the pressure of pulmonary vasculature in which a recruitment of blood flow occurs as $P_I$ and the proportion of change in pulmonary artery to that in cardiac output as IR and then we compare PI and IR with pulmonary vascular resistance, we would find some problems in pulmonary vascular resistance. In other words, it is the theory that, IR should be increased mainly in pulmonary embolism in which decreases the cross sectional area of pulmonary vasculature. But there are many contradictory reports resulted from various researches and the fact is known widely that any difference exists between PVR and PI, IR. For this reason, the purpose of this study is to observe how PI and IR change at the time of the outbreak and during treatment of the pulmonary embolism, and to find out the meaning of these new indicators and the difference from the pulmonary vascular resistance used generally when we subdivide the pulmonary vascular resistance into PI and IR. Method: After making AV fistula in experimental dog, we controlled cardiac output at the intervals of 15 minute in case of three kinds(all AV fistula are obstructed, only one of fistula is open and all of fistula is open), and after evoking massive pulmonary embolism with radioactive autologous blood clots, we measured the mean pulmonary artery pressure, and calculated PI and IR. We observed the pattern of change in PI and IR, without giving the control group any specific treatment and with injecting intravenously rtPA in the Group 1 and Group 2 at the dose of 1mg per kg, for 15 minutes fot the former and 3 hours for the latter. Result: 1) Pulmonary vascular resistance showed a change similar to that of pulmonary artery pressure and in all three group, PVR increased significantly, but group 1 and group 2 showed tendency that PVR keeps on decreasing after treatment, and the rate of decrease in group 1 is more rapid than group 2 significantly. 2) Both intersection(PI) and degree(IR) are proved statistically significant, in view of the straight line relationship between cardiac output and pulmonary artery pressure, calculated by minimal regression method. 3) PI changed similarly to pulmonary vascular resistance, while in the IR which is theoretically more similar to PVR, there was no significant difference or change after rtPA infusion. Conclusion: In the pulmonary embolism, Both change in IR which means real resistance of pulmonary vasculature and PI which was developed due to secondary vasoconstriction by pulmonary embolism are reflected same time.

Background : The tuberculin skin test has been used to diagnose latent tuberculosis infection, but is not widely used to diagnose or exclude pulmonary tuberculosis. The objective of this study was to evaluate the diagnostic utility of the tuberculin test in diagnosing and excluding pulmonary tuberculosis, and differentiating pulmonary tuberculosis from nontuberculous mycobacteria (NTM) pulmonary disease, when a sputum acid-fast bacilli (AFB) smear was positive. Material and Methods : From October 2002 to August 2003, among all the inpatients of the Division of Pulmonary and Critical Care Medicine at Samsung Medical Center, 258 patients with clinical suspicion of pulmonary tuberculosis were enrolled and underwent a tuberculin test. Results : 156 males and 102 females were included, with a mean age of 57.5 years. The final diagnoses included lung cancer in 89 cases (34.5%), pulmonary tuberculosis in 59 cases (22.9%), bacterial pneumonia in 33 cases (12.8%) and NTM pulmonary disease in 24 cases (9.3%). The positive tuberculin test rate was higher in the tuberculosis than non-tuberculosis group; 81.4 (48/59) vs. 42.4% (81/199). (p<0.001). In 208 patients with a negative sputum AFB smear, the result of the tuberculin test was positive in 69.4% (25/36) of the tuberculosis group and in 44.8% (77/172) of the non-tuberculosis group (p=0.007), so a positive result of the tuberculin test could predict pulmonary tuberculosis with 69.4% sensitivity, 55.2% specificity, a 24.5% positive predictive value and a 89.6% negative predictive value. In 50 patients with a positive sputum AFB smear, the positive rates of the tuberculin test were 83.9% (26/31) in tuberculosis group and 21.1% (4/19) in NTM pulmonary disease group (p<0.001), so a positive result of the tuberculin skin test could predict pulmonary tuberculosis with 83.9% sensitivity, 78.9% specificity, a 86.7% positive predictive value and a 75.0% negative predictive value. Conclusion : The tuberculin test could be useful in excluding pulmonary tuberculosis when the sputum AFB smear is negative, and to differentiate pulmonary tuberculosis from NTM pulmonary disease when the sputum AFB smear is positive.

Pulmonary arterial thrombosis develops during hypercoagulable states, intra-arterial tumorous conditions, and congenital heart disease accompanied by pulmonary hypertension. Thrombosis in the main pulmonary arterial stump after pneumonectomy can also occur. Herein, we report a very rare case of pulmonary arterial thrombosis in a patient with pulmonary hypertension and a lung destroyed by tuberculosis. He presented with aggravated dyspnea without fever or purulent sputum. His chest computerized tomography scan showed left main pulmonary arterial thrombosis as a convex shape, with the ipsilateral distal arteries and arterioles showing parenchymal destruction. After excluding pulmonary thromboembolism and hypercoagulable disorders, we diagnosed pulmonary arterial thrombosis and treated him with an anticoagulant.

Objective: To explore the feasibility of pulmonary lobectomy combined with pulmonary arterioplasty by complete video-assisted thoracic surgery (VATS) in patients with lung cancer, and summarize its surgical methods. Materials and Methods: Twenty-one patients with lung cancer in Beijing Chest Hospital Affiliated to Capital Medical University from Feb., 2010 to Jun., 2013 were selected, males and females accounting for 15 and 6 cases, respectively. Ten underwent right upper lobectomy, 5 right lower lobectomy, 4 left upper lobectomy (in which left upper sleeve lobectomy was conducted for 2) and 2 left lower lobectomy. At the same time, local resection of pulmonary arterioplasty was performed for 12 patients, and sleeve resection of pulmonary arterioplasty for 9. Results: Twenty-one patients recovered well after surgery. Thoracic drainage tube was maintained for 3-8 days, with an average of 4.9 days, and hospital stays were 8-15 days, with an average of 11 days. There were no deaths in the perioperative period, and the complications like pulmonary embolism, bronchopleural fistula, chest infection and pulmonary atelectasis did not occur after surgery. Conclusions: Performance of pulmonary lobectomy and pulmonary arterioplasty together by complete VATS is a safe and effective surgical method, which can expand the indications of patients with lung cancer undergoing thoracoscopic pulmonary lobectomy, and make more patients profit from such minimally invasive treatment.
