目的应用超声观察急性肺血栓栓塞症(PTE)患者血栓直接征象。方法选择资料完整、符合PTE诊断标准的PTE患者502例,其中大面积、次大面积PTE224例(溶栓治疗),非大面积PTE278例(抗凝治疗)。超声观察治疗前和治疗后(14d)右心系统血栓直接征象和下肢静脉血栓情况。结果超声检查发现右心系统血栓直接征象者31例,占6.2%。治疗前溶栓组血栓直接征象28例(11.6%),治疗后为8例(4.0%),P﹤0.01。抗凝组血栓直接征象6例(2.9%),治疗后2例(0.9%),P﹥0.05。502例患者检出下肢静脉血栓者326例(64.7%),治疗前发现静脉血栓血管数为785条(11.2%),治疗后仍存在血栓者458条(6.5%),P﹥0.05。结论超声检测PTE患者血栓直接征象可有助于观察治疗前后变化,以溶栓治疗对血栓直接征象改善显著。下肢静脉血栓短期治疗改善缓慢。
Objective To observe the direct signs of thrombus in patients with acute pulmonary thromboembolism (PTE) by using ultrasound. Methods A total of 502 PTE patients with complete data and PTE diagnostic criteria were selected. Among them, 224 were PTE (large-area and sub-large area) (thrombolytic therapy) and 78 were non-large-area PTE (anticoagulant therapy). The symptoms of right ventricular systolic thrombosis and venous thrombosis of lower extremities were observed before and after treatment (14 days) by ultrasound. Results Ultrasound examination revealed 31 cases of direct signs of right heart thrombosis, accounting for 6.2%. There were 28 cases (11.6%) of thrombosis in thrombolysis group before treatment, 8 cases (4.0%) after treatment, P <0.01. There were 6 cases (2.9%) of direct thrombosis in anticoagulation group and 2 cases (0.9%) after treatment, P> 0.05. There were 326 cases (64.7%) in 326 cases of venous thrombosis of lower extremity detected in 222 cases. 785 (11.2%), 458 (6.5%) were still thrombosis after treatment, P> 0.05. Conclusion The direct detection of thrombus in patients with PTE by ultrasound can be helpful in observing the changes before and after treatment. Thrombolytic therapy can improve the direct signs of thrombus. Short-term treatment of venous thrombosis slow improvement.
