摘要
目的探讨基层医院经胸超声心动图在肺栓塞诊断及鉴别诊断中的应用价值。方法回顾2007年1月-2012年2月38肺栓塞患者临床资料,所有患者均经增强计算机断层摄影术（CT）诊断。应用SPSS 13.0软件对超声心动图及肺CT结果进行分析。结果超声示肺动脉分叉处血栓1例（2.6%）,右心增大14例（36.8%）,肺动脉增宽13例（34.2%）;肺动脉压轻度增高13例（34.2%）,中度增高6例（15.8%）,重度增高7例（18.4%）;D型征9例（23.7%）,左心增大7例（18.4%）,大致正常4例（10.5%）。CT示肺动脉主干及双支病变20例（52.6%）,动脉分支及单支病变18例（47.4%）。分支或单支病变者,超声示右室内径（22.5±3.2）mm,肺动脉压力（25.5±26.4）mm Hg;双支及主干病变者,超声示右室内径（26.96±4.7）mm,肺动脉压力（56.3±25.4）mm Hg;两组右室内径及肺动脉压力比较,差异有统计学意义（P〈0.05）。结论超声心动图不但可以对肺栓塞高危患者进行筛查,更重要的是可与心脏急危重症进行鉴别。在基层医院经胸超声心动图在肺栓塞诊断及鉴别诊断中具有重要应用价值。
Objective To explore the application value of transthoracic echocardiography in diagnosis and differential diagnosis of pulmonary embolism in basic-level hospital.Methods Clinical date of 38 patients with pulmonary embolism were analyzed retrospectively from January 2007 to February 2012,all patients were diagnosed by enhanced computed tomography（CT）.The echocardiography and lung CT results were analyzed by software SPSS 13.0.Results 1 case（2.6%） was found thrombosis in pulmonary artery bifurcate place by echocardiography;14 cases（36.8%） were found right-entricular enlargement;13 cases（34.2%） were found pulmonary artery broadening;pulmonary artery pressure of 13 patients（34.2%） had slightly increasing,which of 6 patients（15.8%） had moderately increasing,and 7 cases（18.4%） had severely increasing.9 cases（23.7%） had D type;7 patients（18.4%） had left-entricular enlargement and 4 cases（10.5%） had roughly normal results.CT showed that 20 cases（52.6%） had main pulmonary artery or double blood vessels embolism,18 cases（47.4%） had branch or single blood vessel embolism.Echocardiography showed right ventricular diameter and pulmonary arterial pressure in patients with branch or single blood vessel embolism were（22.5±3.2） mm and（25.5±26.4） mm Hg,which in patients with main pulmonary artery or double blood vessels embolism were（26.96±4.7） mm and（56.3±25.4） mm Hg;the differences were statistically significant（P 0.05）.Conclusion Echocardiography not only can screen high-risk patients with pulmonary embolism,but also can identify it with acute or critical heart diseases.In basic-level hospital,transthoracic echocardiography has important application value in diagnosis and differential diagnosis of pulmonary embolism.
