【摘要】 目的 :了解肺血栓栓塞症 (PTE)的发病特点。方法 :回顾性分析 10 2例PTE的临床表现特点、胸部CT平扫、肺通气和灌注核素显像特点 ,并对胸部CT平扫和肺通气和灌注核素显像结果进行对比。结果 :深静脉血栓形成 (DVT)是导致PTE的最主要危险因素。慢性心肺疾患、外科手术、创伤及骨折和恶性肿瘤也是PTE的主要危险因素。本组病例肺通气和灌注核素显像呈高度可疑 (HP)者为 87.5 %。本组病死率 15 .7%。结论 :PTE仍是一个易被临床忽视的疾病 ,应密切加强关注其临床特征并综合加以分析 ,其胸部CT平扫的影像学特点对PTE的诊断价值也不容忽视更多还原

【Abstract】 Objective: To enhance the recognition and diagnosis of pulmonary thromboembolism(PTE).Methods:A retrospective study was done to analyze 102 cases of patients with PTE with respective to the characteristics of clinical manifestation,the radiography of chest CT scan,ventilation and perfusion (V/Q) scan,and comparison of the results between CT scan and V/Q scan. Results: Deep venous thrombosis (DVT) was a dominant risky factor to PTE.The other risky factors included chronic cardiopulmomary diseases,surgical operation,trauma,bone fracture and malignant tumors.The study found a 87.5% of High probability(HP) with V/Q scan in the group.A mortality of 15.7% was also revealed in the patients.Conclusion: PTE is still the illness which is often ignored in clinical practice.A close attention should be paid to the clinical features of the disease.The varied of the characteristics of the CT scan is of a important value in diagnosis of the disease.更多还原
