Perfusion and ventilaion imagings of the lung are well established procedure for diagnosing pulmonary embolism, differentiation it from chronic obstructive lung disease, and making an early detection of chronic obstructive lung disease. To evaluate the usefulness of radioaerosol inhalation imaging (RII) in chronic obstructive lung disease, especially pulmonary emphysema, we analyzed RIIs of five normal adult non-smokers, five asymptomatic smokers (age 25-42 years with the mean 36), and 21 patients with pulmonry emphysema (age 59-78 years with the mean 67). Scintigrams were obtained with radioaerosol produced by a BARC nebulizer with 15 mCi of Tc-99m-phytate. Scanning was performed in the anterior, posterior, and lateral projections after five to 10-minute inhalation of the radioaerosol on sitting position. The scans were analyzed and correlated with the results of pulmonary function studies and chest radiographs. Also lung perfusion scan with $^{99m}Tc-MAA$ was performed in 12 patients. In five patients, we performed follow-up scans for the evaluation of the effects of a bronchodilator. Based on the X-ray findings and clinical symptoms, pulmonary emphysema was classified into four types: centrilobular (3 patients), panlobular (4 patients), intermediate (10 patients), and combined (4 patients). RII findings were patternized according to the type, extent, and intensity of the aerosol deposition in the central bronchial and bronchopulmonary system and lung parenchyma. 10 controls, normal five non-smokers and three asymptomatic smokers revealed homogeneous parenchymal deposition in the entire lung fields without central bronchial deposition. The remaining two of asymptomatic smokers revealed mild central airway deposition. The great majority of the patients showed either central (9/21) or combined type (10/21) of bronchopulmonary deposition and the remaining two patients peripheral bronchopulmonary deposition. Parenchymal aerosol deposition in pulmonary emphysema was diffuse (6/21), discrete(6/21), intermediate (3/21), or combined (6/21). In 12 patients studied also with perfusion scans, perfusion defects matched closely with ventilation defects in location and configuration. But the size of the ventilation defects was generally larger than the perfusion defects. In all four patients treated with bronchodilators, the follow-up study demonstrated decrease in abnormal of radioaerosol deposition in the central airway with improvement of ventilation defects. RII was useful technique for the evaluation of regional ventilatory abnormality and the effects of treatment with bronchodilators in pulmonary emphysema.

Acute respiratory failure has become an increasingly frequent cause of death following shock or trauma. Interstitial or diffuse alveolar edema, as chief pathophysiologic change of acute respiratory insufficiency, can be the result of sepsis, fat embolism, cardiac failure, lung congestion, and oxygen toxicity. These pulmonary problems are extremely difficult to treat without early recognition of their development and aggressive management. If the treatment is delayed, the progressive respiratory failure is almost uniformly fatal. Authors have experienced two cases of acute respiratory insufficiency following the blunt chest trauma, which were healed uneventfully. Literatures were briefly reviewed.

In Behcet syndrome, cardiac involvements are rare and have been reported pericarditis, myocarditis, right heart endocardial fibrosis, right ventricle mural thrombus with pulmonary embolism, active endocarditis, granulomatous endocarditis, conduction disturbance, acute aortic insufficiency, mitral valve prolapse. Our three patients underwent AVR because of aortic insufficiency and ascending aorta enlargement combined with Behcet syndrome. Two patients had mitral regurgitation too. So one underwent MAP and the other underwent MVR concomitantly. One who underwent AVR have been well for 50 months. Another who underwent AVR+MAP and redo AVR due to aortic paravalvular leakage was died of congestive heart failure. The other who underwent AVR+MVR and repeated AVR three times because of aortic paravalvular leakage is in condition of aortic paravalvular leakage. Paravalvular leakage is considered to recur due to progressive dilatation and fragility of aortic root that is the result of pathologic change of Behcet syndrome in it. If Open heart surgery is needed in Behcet`s syndrome during inflammatory reaction is active, postoperative complications such as paravalvular leakage or suture line rupture may be prevented with pre- and postoperative anti-inflammatory management.

Congenital coronary arteriovenous fistula is relatively uncommon and widespread use of echocardiogram and selective coronary angiogram are being recognized with increasing frequency. The right coronary artery is most commonly involved and the fistulous communication is most common to right ventricle. Surgical correction is strongly recommended to prevent the development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and pulmonary hypertension, as well as coronary aneurysm formation, with subsequent rupture or embolism. We report two cases of coronary arteriovenous fistula originated from right coronary artery terminated in the right ventricle. These 8 year-old female and 7 year-old male patients had surgical interventions using cardiopulmonary bypasses.

This is a report of a case in which a left atrial myxoma was successfully removed by total cardiopulmonary bypass with total hemodilution and moderate hypothermia. The patient was a 17 old girl with mitral valvular symptoms that occured suddenly three months prior to operation. After the onset of symptoms. it was progressively aggravated to serious general condition. The preoperative diagnosis of left atrial tumor was made from echocardiography. and the tumor was confirmed as myxoma by the histopathological examination of the tumor tissue removed during operation. The myxoma was unusually originated from posterior wall of the left atrium. which was located between drainage orifices of right and left pulmonary veins, The tumor developed in the left atrial cavity and one of the polypoid processes of the myxoma was prolapsed into the the left ventricle through the mitral orifice. Following operation. there was no evidence for peripheral vascular embolism, and all valvular symptoms disappeared. The postoperative course was uneventful.

Venous thromboembolism, encompassing deep vein thrombosis and pulmonary embolism, has increased in cancer patients and adversely affects their prognosis. Low-molecular-weight heparins are recommended as efficacious and safe anticoagulation treatment in cancer patients. However, in practice, oral anticoagulation is preferred, especially if longterm or extended treatment is necessary. Novel oral anticoagulants have recently emerged as an alternative to the standard therapy owing to the ease of administration, predictable anticoagulation effect without the need of laboratory monitoring, and fewer drug interactions. These new agents have been shown as effective and safe for the management of cancer-associated thrombosis in ongoing head-to-head comparative trials. Here we review the advances and limitation of current anticoagulant therapies.

Central venous catheterization via an internal jugular vein or subclavian vein has become a common procedure in monitoring CVP and managing severely ill patients. However, there have beennumerous reports of complications associated with central venous catheterization. These include vessel injury, pneumothorax, hemothorax, nerve injury, arrhythmias, arteriovenous thrombosis, pulmonary embolism, and infection at the insertion site. We report a case of hemothorax after subclavian vein catheterization failure, along with successful treatment.

No one technique provides an optimal outcome for all body contouring patients. There are many surgical options for abdominoplasty. Among these, this abdominoplasty without undermining consists of liposuction around abdominal subcutaneous fatty tissue, excision of lower abdominal flap. The procedure allows aggressive thinning and sculpting of abdominal flap. This operation minimizes the dead space, which often leads to postoperative complications, and preserves neurovascular supply to the abdominal skin. From 1999 to 2004, 18 patients underwent the abdominoplasty without undermining, resulting in high satisfaction rates with no significant complications, such as, pulmonary embolism and deep vein thrombosis. Patients could return to normal activity within a week. This abdominoplasty without undermining is an effective and safe alternative with low complication rate and enhances aesthetic results compared to traditional abdominal surgery.

During the 4 years period to be reported, 34 operations were performed on the mitral valve in the department of Thoracic and cardiovascular surgery, Korea University hospital, from Aug. 1975 to April 1979. At the first 1-year period, the closed technique was used in 12 patients. After that, open-heart surgery was used routinely; 8 patients had open mitral commissurotomy and 14 patients had valve replacement. There were 18 men and 16 women with sex ratio of 1.1: 1. The age of the patients varied widely from 18 years of the youngest to 46 years of the oldest-average aged of 32.5 years. All had symptoms and the mean duration of symptoms was 6 years and 1 month. Preoperative atrial fibrillation was 47% and embolizations were in 3 of 34 patients. The operative mortality was none for the closed and 14% for the open technique combined rate of 9 per cent which were valve thrombosis, brain embolism and left pulmonary vein rupture in deauriculization. But surviving patients undergoing open heart surgery enjoyed symptomatic benefits comparable to these of the patients of closed.

From July 1988 to January 1991 six patients, aged 29 to 70 years underwent transfemoral thrombectomy for the treatment of deep vein thrombosis. Preoperative venograms showed thrombi in the following locations: calf veins[five], superficial femoral or popliteal veins [four], common femoral veins[three], and iliac veins[three], Durations of symptoms before admission were from 1 day to 20days. Operations were performed under local anesthesia and all the patients were requested for doing Valsalva maneuver during thrombectomies. All patients were received heparin pre-and postoperatively, which was switched to Coumadin for preventing of rethrombosis. One patient was transferred to other hospital 4 months after operation due to regional reason, and the remained five patients were evaluated with a mean follow-up time of 20 months. There was no evidence of postoperative pulmonary embolism. Three of five patients were clinically asymptomatic. One complained of the heaviness of involved leg in the evening, and the other had discomfort on walking Even though our cases were a few in number, we concluded that thrombectomy is a valuable treatment modality of deep vein thrombosis.
