摘要
目的探讨肺血栓栓塞症(PTE)的临床特征和诊断方法。方法对89例PTE确诊的病例进行回顾性分析。结果PTE患者常有多种危险因子,最常见的临床表现为不明原因的呼吸困难,伴有下肢深静脉血栓形成,其他常见的症状和体征包括呼吸急促、胸痛和心动过速等。动脉血气分析、心电图、胸部X线、超声及D-二聚体试验对PTE诊断有提示作用;核素肺通气/灌注扫描和CT肺动脉造影是诊断PTE最常用的技术。结论PTE是一种常见肺血管疾病,对不明原因呼吸困难的高危患者应及时给予确诊试验,如核素肺通气/灌注扫描和CT肺动脉造影。
Objective To explore the clinical feature and diagnostic approach to pulmonary thromboembolism （PTE）. Methods Retrospective analysis of clinical deta of 89 patientyconfirmed PTE was. Results The patients with PTE often had one or more risk factors. The most common clinical manifestation of PTE was unexplained dyspnea with deep venous thrombosis （DVT） in the lower extremity. Other common symptoms and signs included tachypnea, chest pain and tachycardia. Blood gas analysis, electrocardiography, chest X ray, uhrasonography and D-dimer testing were predictive for the diagnosis of PTE. Ventilation-perfusion （V/Q） scanning and CT pulmonary angiography （CTPA） were common diagnostic techniques for PTE. Conclusion PTE is a common disease involved in the lung vasculature. High risk patients with unexplained dyspnea should have diagnostic tests early, such as, ventilation-perfusion scanning and CT pulmonary angiography.
