Purpose: This study was done to examine the relationship among knowledge, health belief, and preventitive behavioral intention related to venous thromboembolism (VTE) in patients with lower-limb musculoskeletal disorders. Methods: This transversal descriptive study looked at 145 adult patients with lower-limb musculoskeletal disorders, who were hospitalized in C hospital in G city. Data were collected from September 29 to October 6, 2012. Knowledge, health belief and preventitive behavioral intention were measured by structured questionnaires. Date were analyzed by descriptive statistics, one-way ANOVA, independent t-test, and Pearson correlation, using the SPSS program. Results: The mean score of knowledge related to VTE was low. The mean scores of health belief and preventitive behavioral intention related to VTE were moderate or higher than average. Preventitive behavioral intention positively correlated with knowledge, perceived benefit, and health motivation. Whereas, there was a negative correlation between preventitive behavioral intention and perceived barriers. Conclusion: These results suggest that developing a health care program which is able to enhance knowledge, perceived benefit, and health motivation related to VTE and reduce perceived barriers, is essential in order to promote preventitive behaviors.

Purpose: The purpose of this study is to identify knowledge, awareness, and risk of occurrence of venous thromboembolism among pregnant women. Methods: Subjects were 106 pregnant women treated as inpatients and outpatients at a women's health hospital in a metropolitan city February 19-March 22, 2018. Instruments consisted of questionnaires that included knowledge, awareness, and risk of occurrence of venous thromboembolism queries. Collected data were analyzed by t-test, one-way analysis of variance, Mann-Whitney U test and Kruskal-Wallis test. Results: Mean score of subjects' knowledge of venous thromboembolism was 4.47 (0-15), mean score of subjects' awareness of venous thromboembolism was 66.98 (25-100), and mean score of subjects' risk factor of venous thromboembolism was 0.98 (0-44). Conclusions: Pregnant women's level of knowledge and awareness of prevention and risk factors on venous thromboembolism, is significantly low. To raise their awareness of risk symptoms and prevent occurrence of the disease, it is essential for nurses as well as medical staffs to: 1) provide an educational program on venous thromboembolism for patients; 2) assess and monitor pregnant women with a risk factor of venous thromboembolism; and 3) implement proper prophylaxis for patients.

We report a rare case of pulmonary artery sarcoma mimicking pulmonary artery thromboembolism in a 57-year-old man who suffered with 2-month dyspnea and exacerbated for 1 week. He was transferred from private clinic and he was diagnosed as acute pulmonary artery thromboembolism on the basis of chest CT. Chest CT, pulmonary artery angiogram, and perfusion scan were examined. We performed surgical excision with aid of CPB. The final pathologic report was that the mass was a pulmonary artery sarcoma. We experienced one case of pulmonary artery sarcoma and reported it with reference.

The estimated relative incidence of primary pulmonary sarcoma to lung cancer is 0.4%. Furthermore, osteogenic sarcoma of the pulmonary artery is extremely rare. We report a case of a 63-year-old woman who visited our emergency room with the chief complaints of chest pain, dyspnea and dizziness. On echocardiography, right heart failure due to acute pulmonary artery embolism was diagnosed and we performed emergency operation. After opening the main pulmonary artery trunk, we found a mass attached to the arterial wall and massive thrombi around the mass. The mass was diagnosed as primary pulmonary artery osteosarcoma through postoperative evaluation. The patient received chemotherapy and radiotherapy. The patient is alive without specific symptoms 16 months postoperatively.

Background : Vital stability and right side heart failure are major prognostic factors of acute pulmonary thromboembolism. While it is important to recognize right side heart failure, it is often difficult in real practice. Recently, several studies have described early diagnostic tools for detecting right side heart failure including echocardiography and biochemical markers. This study, we evaluated the prognostic role of the B-type natriuretic peptide (BNP) in an acute pulmonary thromboembolism. Methods : Thirty-four patients with a diagnosis of acute pulmonary thromboembolism were enrolled in the study. The BNP levels were measured and echocardiography was performed at the Emergency Department. Data on the prognostic factors including ventilatory support, vital stability, pulmonary artery pressure, degree of tricuspid valve regurgitation, complications and death was collected from the patients' medical records. The patients with an acute pulmonary thromboembolism were divided into two groups based on the vital stability and the BNP level and the cutoff values and prognostic factors of the two groups were compared. Results : The predictors of the vital stability that influence the prognosis of patients with acute pulmonary thromboembolism were the BNP level, ventilatory support and death. The plasma BNP levels showed a strong correlation with the vital stability, ventilatory support, thrombolytic therapy and death. When the BNP cutoff level was set to 377.5 pg/dl in a ROC curve, the sensitivity and the specificity for differentiating between the groups with stable or unstable vital signs was 100% and 90%, respectively. Conclusion : This study indicates that a measurement of the plasma BNP levels may be a useful prognostic marker in patients with an acute pulmonary thrombo-embolism.

A free-floating ball thrombus in the left atrium that may cause fatal systemic emboli or left ventricular inflow obstruction, which often resulting in sudden death, is rarely seen. We describe a very unusual case of a patient with a large, free-floating left-atrial ball thrombus who underwent mechanical mitral valve replacement 7 years ago.

A 45 year old man was admitted for aggravated dyspnea, abdominal distension and poor oral intake. On Echocardiogram, mitral stenosis(severe), tricuspid regurgitaion(IV), and LA thrombus were diagnosed. We used heparin with continuous infusion for prevention of systemic thrombo embolism. On the 11th day of admission, the patient showed thrombocytopenia and we suspected Heparin-induced thrombocytopenia. Hirudin was used in this case as alternative anticoagulant during cardiopulmonary bypass to prevent serious complication of heparin. The patient was recovered without any complication as postoperative bleeding or systemic thromboembolism.

Interventricular membranous septal aneurysms are rare. Since these aneurysms can lead to complications such as obstruction of right ventricular outflow and thromboembolism, the detection of this aneurysm has clinical significance. Herein, we report a case of an interventricular membranous septal aneurysm with an internal thrombus thought to be the cause of a cerebral infarction.

Pulmonary Embolism can develop in variable conditions, and presents with nonspecific symptoms and signs. If diagnosis is delayed, it can be resulted in catastrophic results. Therefore, early diagnosis and adequate treatment is crucial in Pulmonary Embolism. Lung Perfusion Scan is useful screening test. Negative result can exclude pulmonary embolism. But, perfusion defects don't always mean pulmonary embolism. To find the better methods of interpretation of lung perfusion scan and To evaluate the clinical course and outcomes of the patients, in whom pulmonary embolism was suspected by lung perfusion scan, we reviewed the clinical records of 49 cases suspected by lung perfusion scan at Seoul National University Hospital during the period of January, 1995 to July, 1996. The results are as follows. First impression of cases in which PE was present at time of admission were pulmonary embolism (63%), heart diseases (26%), and pneumonia (11%) in orders. Underlying diseases of cases in which PE developed during admission were malignancy (36.5%), ICH (22.7%), sepsis (13.7%), and SLE (9.1%) in orders. The predisposing factors were operation (20%), cancer (16%), immobility (16%), connective tissue disease (16%), heart dis. (10%), old age (10%), and preg/pelvic dis. (8%) The results, of lung perfusion scan were HPPE 40 cases(26.8 %), IPPE 21 cases(14.1%), LPPE 88 cases (59.1%), and cases(%) of treatment in these cases were HPPE 34 cases(85%), IPPE 9 cases(42.9%), LPPE 0 case(0.0%). Treatments were heparin and warfarin (69.5%), heparin alone (8.2%), warfarin alone (2.0%), embolectomy (4.1%), thrombolytics (2.0%), IVC filter (2.0%), and no treatment (12.2%) In 34 cases (69.4%), follow up could be done, and 5 cases were recurred (10.2%). The causes of recurrence was incomplete anticoagulant therapy (3 cases) and recurrence of predisposing factor (2 cases). Expired case due to pulmonary embolism was one who was expired just before trial of thrombolytic therapy. Conclusion : Efforts should be made to shorten the interval from onset of Sx to Dx, ie, high index of suspision.

Background : 'Major pulmonary thromboembolism' is defined as right ventricular (RV) dysfunction, with or without shock, accompanied by significant morbidity and mortality. In this study, those with major pulmonary thromboembolism were divided into the shock and RV dysfunction only groups, and then investigated the mortality and complications in thrombolysis or anticoagulation, respectively. Methods : In a retrospective study, between January 1995 and December 2004, 60 eligible patients with a major pulmonary thromboembolism, admitted in Asan Medical Center, were included. Results : A total of 57 patients were treated with medical therapy. Thrombolysis was performed in 13 patients (23%) and anticoagulation in 44 (77%). There were no differences in the APACHEII and SOFA scores between the two groups. 6 (46%) and 11 (25%) patients died in the thrombolysis and anticoagulation groups, respectively (p=0.176). In the 19 patients (33%) showing shock, thrombolysis was performed in 9 (47%) and anticoagulation in 10 (53%). 4 (44%) of the 9 patients treated with thrombolytic agents and 3 (30%) of the 10 treated with anticoagulants died (p=0.650). In the 38 patients (67%) showing RV dysfunction only, thrombolysis was performed in 4 (11%) and anticoagulation in 34 (89%). 2 (50%) of the 4 patients treated with thrombolytics and 8 (24%) of the 34 treated with anticoagulants died (p=0.279). Three patients (23%) who underwent thrombolysis had a major bleeding episode, compared with 2 (5%) who were treated with anticoagulants (p=0.072). Conclusion: The results of our study showed that thrombolysis did not lower mortality and tended to increase major bleeding compared with anticoagulation in both the shock and RV dysfunction only groups. Further evaluation of the efficacy and safety of thrombolytic therapy for major thromboembolism appears warranted in Korea.
