急性肺栓塞(acute pulmonary embolism,APE)是一种涉及心肺循环的临床危重症,因其临床表现复杂、多变,起病凶险,病死率高,极易造成临床误诊或漏诊,因此早期诊断、及时治疗是成功救治的关键[1-3]。本研究应用超声心动图对溶栓治疗的30例急性肺栓塞患者的早期疗效评估。1资料与方法1.1病例选择选择山东省烟台山医院2002年12月至2006年4月间由临床表现、心肌酶学、肺动脉CT和/或肺动脉造影证实的APE患者30例,其中男16例,女14例,年龄(62.7±11.3)岁。本组30例于发病3～72h内实行了静脉内滴注组织型纤溶酶原激活剂50mg溶栓治疗。1.2仪器与方… | | |  推荐 CAJ下载  PDF下载 | | | CAJViewer7.0阅读器支持所有CNKI文件格式，AdobeReader仅支持PDF格式 | | | | Cardiographic assessment following thrombolysis for acute pulmonary embolism | | | GUO Fang-ming;XIA Ai-jun;TANG Yan. Department of Echocardiography;Yantai Hill Hospital;Yantai 264001;China | | | Objective To evaluate the cardiographic changes following thrombolysis and anticoagulation for acute pulmonary (embolism with embolus of pulmonary artery and structures and functions of right atrium ventricular. Method Thirty patients with acute pulmonary embolism, confirmed by computed tomographic angiography or angiography of pulmonary artery, were enrolled in this prospective nonrandomized control study and performed thrombolysis therapy between December 2002 and April 2006. The embolus and inner diameter of pulmonary artery,right atrial diameter, right ventricular diameter, right ventricular anterior wall movement, right ventricular end diastolic volume, right ventricular ejection fraction, tricuspid valvular regurgitation and the systolic pressure of pulmonary artery were observed by using transthoracic echocardiography or bedside echocardiography. Results After twenty to thirty six hours and during a month follow-up after thrombolysis,the right heart morphology was increasingly improved,which presented with shortening of right atrium transversal diameter and left-right diameter of the right ventricles,pulmonary artery inner diameter and right ventricular end diastolic volume(P<0.01),increasing of right ventricular anterior wall movement and right ventricular ejection fraction, reducing of pulmonary artery systolic pressure. The pulmonary artery embolus in 5 of 30 patients had been dissolving after the thrombolysis and anticoagulation therapy for one month. Conclusions Echocardiography had important value in evaluating the effects of thrombolysis acute pulmonary embolism in timing and non-invasive way, especially in probing embolus dissolved, right atrium-ventricular structure, right ventricular over-load and pulmonary hypertension.
