摘要:目的： 分析肺動脈血栓栓塞癥（PTE）的臨床特征、診斷方法及治療。提高診斷率和治愈率,改善預后。 方法 ：回顧分析我院過去七年間收治的25例PTE患者的危險因素、臨床表現、輔助檢查、治療情況等臨床資料。 結果 ：PTE的危險因素有深靜脈血栓、高齡、心肺疾病、長期臥床等慢性基礎疾病以及近期手術、外傷史等。其臨床表現各異,D-二聚體、CT肺動脈造影（CTPA）敏感性高。 結論 ：PTE臨床表現多樣,D-二聚體可作為篩選檢查首選;CTPA可作為無創檢查之首選。確診后正確及時治療可使預后顯著改善。Abstract: Objective: to analyze the clinical character\ methods of diagnosis and therapies of pulmonary thrombus embolism, to improve the precisions of diagnosis and therapy, to make prognosis better. Method : 25 patients of pulmonary thrombus embolism admitted in our hospital in the past seven years, were analyzed by risk factors, clinical manifestation accessory examination and therapies. Result : risk factors of pulmonary thrombus embolism included thrombus in venue profound, senility the diseases of heart and lung, keeping in the bed for a long time, above clinic diseases, operation and trauma in the near future their clinical manifestations were different, the sensitivity of dipolymer and CT pulmonary arteriography were high. Conclusion : clinical manifestations of pulmonary thrombus embolism were various, dipolymer may be regarded as the firster to diagnbose pulmonary thrombus embolism, CT pulmonary arteriography may be regarded as the first non-traumatogenic examination to diagnose pulmonary thrombus emboklism. After the diagnosis, correct therapies in time can greatly improver prognosis.
