ABSTRACT
Background: Pulmonary Thrombo-Embolism (PE) is a common and potentially lethal complication of deep venous Thrombosis (DVT). High sensitivity and specificity of Multi Detector Computed Tomography Pulmonary Angiography (MDCT-PA) in direct visualization of embolic material within the pulmonary arteries is due to its improved spatial and temporal resolution. Methods: We conducted a Prospective study to evaluate Non-invasive 256 Slice MDCT-PA in one hundred unselected patients with clinically suspected Pulmonary Embolism. Results: The total number of patients with thrombo-embolic disease in our study was 35 (35%), out of which acute PE & acute DVT were observed in 32% and 8% respectively. The percentage of Sub-segmental emboli among patients with acute PE was 34.37%, segmental thrombi was 87.5% and central thrombi was 96.87%.Conclusion: MDCT-PA possess the advantage of direct visualization and quantification of thrombo-embolic material and hence we advocate it to be the first-line imaging study for patients with clinically suspected PE.
ABSTRACT
Objective To investigate the clinical characteristics of pulmonary artery sarcoma (PAS) and pulmonary thromboembolism(PTE), to improve doctors' awareness and the early diagnosis of PAS.Methods The clinical data of 10 PAS cases confirmed with biopsy were retrospectively analyzed,and 10 cases with PTE were selected as control group.Results (1) Main clinical manifestations of the two groups were chest tightness, shortness of breath, intermittent syncope, palpitations, chest pain and cough, and there were no statistical significance differences between the two groups (P＞0.05).(2)There were 2 cases (20.0％) PaO2 ＜80 mmHg in patients with PAS.However, there were 8 cases (80.0％)PaO2 ＜ 80 mmHg in control group.The two groups had statistically significant difference (x2 =7.200, P =0.023).(3) Wells score : the cases with PAS was in low risk (80.0％ and 10.0％),however, the cases of control group was in medium and high risk(90.0％ and 20.0％).The two groups had statistically significant difference (P =0.005, 0.001).(4) The two groups had no statistically significant difference in ECG, UCG, X-ray, lung ventilation/perfusion (P＞ 0.05).(5) There had statistically significant difference in terms of LDH and CRP between PAS and PET group (100％ vs.0, x-2 =10.796,P=0.003;100％ vs.0, x2 =15.000, P =0.000).There was faster ESR in PAS group than control group,and the two groups had statistically significant difference (75％ vs.0, x2=1.400, P =0.011).There was no case of D-Dimer＞500 μg,/L in PAS group, while 10 cases in control group, and the two groups had significant statistical difference (x2 =17.000, P =0.000).(6) There was 1 case (12.5％) with DVT in PAS group, 6 cases (60.0％) in PTE group, and the two groups had significant statistical difference (x2=10.568, P =0.001).(7) The CTPA in PAS group showed filling defect in the main pulmonary artery trunk (85.7％ vs.0) ,left pulmonary artery (85.7％ vs.10.0％) ,right pulmonary artery(100％ vs.10.0％) and both left and right pulmonary artery (85.7％ vs.10.0％), the two groups had significant statistical difference (x2 =13.247, P =0.001;x2 =9.746, P=0.004;x2 =13.388, P =0.000;x2 =9.746, P =0.004).Conclusion PAS and PTE can' t be distinguished from the clinical symptoms, ECG, UCG, X-ray,lung ventilation/perfusion imaging.PAS is easily misdiagnosed as PTE.More attention should be given.PAS can be identified early through the blood gas analysis, hypoxemia,Wells score, LDH, CRP, ESR, D-Dimer, DVT and CTPA.
ABSTRACT
When treating coxarthrosis, each treatment method including conservative treatment, osteotomy, or artificial joint replacement, has an optimal stage for treatment of the disease. Joint preservation surgery has a good result for cases in the early stage, but total hip arthroplasty (THA) is selected for advanced stage hip osteoarthritis, and in Japan, more than a 40000 THAs are performed each year. Good postoperative results lasting up to 15 years are reported today, but, on the other hand, postoperative problems still clearly exist. Deep venous thrombosis/pulmonary embolism (VTE/PTE) are given as perioperative problems, and postoperative dislocation and postoperative range of motion of the hip joint are given as the problems that most relate to ADL. These days, information about THA is abundant so that there is extensive demand for the procedure amongst patients, and elevated technique is demanded of the surgeon. The onset of postoperative VTE/PTE as a lethal complication and interest about its prevention have risen these days with the increase in the number of artificial joint replacements performed in Japan. This time, we introduce a postoperative THA rehabilitation schedule and report the results of our postoperative complication prevention efforts carried out in our hospital. When THA of late years is thought about, for a patient, it is natural that the long-term results are good, and the postoperative satisfaction degree from an early stage is the demand that it is necessary. In consideration of these things, the range of hip motion needed about the origin and preventing dislocation that were one element of long-term satisfaction since only a short-term of normal ADL movement was investigated, and this was viewed from the aspect of joint stability against postoperative dislocation by difference in the approach method of surgery. Finally, we also discussed the importance of early rehabilitation after surgery for the prevention of VTE/PTE as a serious complication of surgery.
ABSTRACT
El tromboembolismo pulmonar (TEP) es una posibilidad diagnóstica que obliga a determinar una probabilidad a través del puntaje (score) de Wells, con el fin de evitar subdiagnósticos o realizar diagnósticos tardíos en el servicio de urgencias. En ocasiones el TEP se presenta como una condición amenazante de la vida que requiere intervención inmediata, siendo la trombolisis el tratamiento adecuado cuando se acompaña de inestabilidad hemodinámica y no hay contraindicaciones para su realización. Se presenta el caso de un hombre de 61 años que ingresa a un servicio de urgencias de alto nivel de complejidad, con diagnóstico de TEP masivo y se procede a trombolisis con Alteplase®, obteniéndose adecuada reperfusión de la circulación pulmonar y estabilidad cardiorrespiratoria luego de realizar el procedimiento.
Pulmonary thromboembolism (PTE) is a diagnosis possibility that implies determining a probability with Wells score in order to avoid subdiagnosis or late diagnosis in emergency services. In some occasions, it presents as a life threatening condition that requires immediate intervention. Thrombolysis is the adequate treatment when PTE is accompanied with hemodynamic instability and when there are no counter-indications. The following article describes the case of a 61 year old man who enters a high complexity level emergency service with a diagnosis of massive PTE and thrombolysis is carried out with Alteplase ®. Adequate reperfusion of pulmonary circulation is obtained as well as cardio respiratory stability following the procedure.

Pulmonary thrombo-embolism in operating room is one of the important cause of morbidity and mortality in patients undergoing femur neck fracture surgery. However, the diagnosis of pulmonary thromboembolism may not be easy because sudden shock can have many different causes (e.g. myocardial infarction, hypovolemia, pneumothorax, non-cardiogenic pulmonary edema, pulmonary thrombo- embolism) and specialized diagnostic tools are not readily available in the operating room. Rapid and accurate diagnosis of pulmonary thromboembolism is very important in outcome of patients. We report a case in which pulmonary thromboembolism under spinal anesthesia occured just before the beginning of operation.
