目的分析肺血栓栓塞症(PTE)患者临床资料,寻找诊断依据。方法对40例确诊PTE患者临床资料进行回顾性分析,探索诊断的敏感指标。结果40例患者,存在高危因素占95%,最常见原因是深静脉血栓脱落占75%。临床表现中最常见是呼吸困难占65%。血气分析异常占80%,心电图变化以V1~V4导联ST-T改变最多,超声心动图异常占90%,表现为右房、右室增大,肺动脉增宽。D-二聚体阳性率为90%。结论患者存在高危因素,出现临床难以解释的呼吸困难、晕厥,结合D-二聚体阳性应考虑肺血栓栓塞症,CT肺动脉造影(CTPA)、核素肺通气/灌注扫描、肺血管造影是确诊PTE的主要检查手段。
Objective To analyze the clinical data of patients with pulmonary thromboembolism (PTE) and find the basis of diagnosis. Methods The clinical data of 40 patients with confirmed PTE were retrospectively analyzed to explore the diagnostic sensitivity index. Results Forty patients had 95% risk factors, the most common cause was deep venous thrombosis (75%). The most common clinical manifestation is dyspnea 65%. Blood gas analysis abnormalities accounted for 80%, ECG changes to V1 ~ V4 lead ST-T changes the most, echocardiographic abnormalities accounted for 90% of the performance of the right atrium, right ventricular enlargement, pulmonary artery widening. D-dimer positive rate of 90%. Conclusions Patients with high risk factors, clinically unexplained dyspnea and syncope, pulmonary thromboembolism in combination with D-dimer-positive disease, CT pulmonary angiography (CTPA), radionuclide ventilation / perfusion scan, and pulmonary angiography were diagnosed PTE’s main means of inspection.
