摘要:目的： 分析肺动脉血栓栓塞症（PTE）的临床特征、诊断方法及治疗。提高诊断率和治愈率,改善预后。 方法 ：回顾分析我院过去七年间收治的25例PTE患者的危险因素、临床表现、辅助检查、治疗情况等临床资料。 结果 ：PTE的危险因素有深静脉血栓、高龄、心肺疾病、长期卧床等慢性基础疾病以及近期手术、外伤史等。其临床表现各异,D-二聚体、CT肺动脉造影（CTPA）敏感性高。 结论 ：PTE临床表现多样,D-二聚体可作为筛选检查首选;CTPA可作为无创检查之首选。确诊后正确及时治疗可使预后显著改善。Abstract: Objective: to analyze the clinical character\ methods of diagnosis and therapies of pulmonary thrombus embolism, to improve the precisions of diagnosis and therapy, to make prognosis better. Method : 25 patients of pulmonary thrombus embolism admitted in our hospital in the past seven years, were analyzed by risk factors, clinical manifestation accessory examination and therapies. Result : risk factors of pulmonary thrombus embolism included thrombus in venue profound, senility the diseases of heart and lung, keeping in the bed for a long time, above clinic diseases, operation and trauma in the near future their clinical manifestations were different, the sensitivity of dipolymer and CT pulmonary arteriography were high. Conclusion : clinical manifestations of pulmonary thrombus embolism were various, dipolymer may be regarded as the firster to diagnbose pulmonary thrombus embolism, CT pulmonary arteriography may be regarded as the first non-traumatogenic examination to diagnose pulmonary thrombus emboklism. After the diagnosis, correct therapies in time can greatly improver prognosis.
ObjectiveTo explore the clinical application value of antithrombin Ⅲ (ATⅢ) in pulmonary thromboembolism (PTE).MethodsA retrospective study included 204 patients with confirmed PTE who were admitted to Fujian Provincial Hospital from May 2012 to June 2019. The clinical data of the study included basic conditions, morbilities, laboratory examinations and scoring system within 24 hours after admission. The relationship between ATⅢ and PTE in-hospital death was analyzed, and the value of ATⅢ to optimize risk stratification was explored.ResultsFor ATⅢ, the area under receiver operating characteristic curve (AUC) of predicting in-hospital mortality was 0.719, with a cut-off value of 77.7% (sensitivity 64.71%, specificity 80.21%). The patients were divided into ATⅢ≤77.7% group (n=48) and ATⅢ>77.7% group (n=156) according to the cut-off value, and significant statistically differences were found in chronic heart failure, white blood cells count, platelets count, alanine aminotransferase (ALT), albumin and troponin I (P<0.05). According to the in-hospital mortality, patients were divided into a death group (n=17) and a survival group (n=187), and the differences in count of white blood cells, ATⅢ, D-dimer, ALT, albumin, estimated glomerular filtration rate and APACHEⅡ were statistically significant. Logistic regression analysis revealed that ATⅢ≤77.7% and white blood cells count were independent risk factors for in-hospital death. The risk stratification and the risk stratification combined ATⅢ to predict in-hospital death were evaluated by receiver operating characteristic curve, and the AUC was 0.705 and 0.813, respectively (P<0.05). A new scoring model of risk stratification combined with ATⅢ was showed by nomogram.ConclusionsATⅢ≤77.7% is an independent risk factor for in-hospital death, and is beneficial to optimize risk stratification. The mechanism may be related to thrombosis, right ventricular dysfunction and inflammatory response.
