Clinical Analysis And Diagnosis Of 66 Patients With Pulmonary Thromboembolism

Objective To analyze the clinical manifestation, diagnosis of pulmonary thromboembolism(PTE) and to improve the diagnostic level of PTE. Methods clinical data of 66 patients with PTE were collected and retrospectively analyzed. Results There is an increasing trend of incidence of PTE in recent years. The prevalence of pulmonary embolism was higher at the age of 61-70 years. Deep venous thrombosis (DVT) was a dominant risky factor to PTE . The other risky factors include chronic cardiopulmonary disease, surgical operation, trauma, bone fracture and malignant tumors. The proportion of misdiagnosis and missed diagnosis was 57. 6% in those patients. In all 66 patients with pulmonary thromboembolism, 91. 2% had hypoxe, 89. 5% had D-Dimer ≥0. 5mg/L , 70% had typical findings on ultrasonic cardiogram, 96. 3% had at least one segmental perfusion defect. The positive rates of CT pulmonary angiography (CTPA) were 95.4% respectively. Conclusion Because the symptoms of PTE are unspecific, it may be difficult to make a clinical diagnosis . The incidence of pulmonary thromboembolism is closely related to the risky factors.A close attention should be paid to the clinical feature of the disease. Blood gas, D-dimer and electrocardiograph could be regarded as convenient means for screening patients with PTE. perfusion lung scanning and CTPA are noninvasive and reliable methods for diagnosing PTE.
