探讨128层螺旋CT在肺动脉栓塞中的应用价值

　　【摘要】 目的：肺動脉栓塞病症患者应用128层螺旋CT进行病症诊断，对其诊断结果进行讨论研究。方法：参与本研究的疑似肺动脉栓塞55例患者均进行128层螺旋CT检查，对其检查诊断结果进行研究讨论。结果：所有患者接受128层螺旋CT检查，诊断结果阳性率为67.27%。从动脉栓塞情况来看其中以叶肺动脉栓塞、肺动脉主干栓塞、段肺动脉栓塞和左右肺动脉栓塞为主，分别为19、1、59和
　　2支，共计81支。将其进行整理归纳可以总结为累及左侧肺动脉和累及右侧肺动脉，其所占比例分别为62.96%和37.04%。经128层螺旋CT检查能够确定动脉血栓的征象可以分成直接征象和间接征象。本研究诊断阳性的37例患者动脉血栓直接表象来讲，其中以附壁性、中心性、完全梗阻和偏心性为主，其四种表现的栓子数量分别为10、27、9和35处。同时再从诊断阳性的37例患者动脉血栓间接征象来看，其中主要包括肺动脉高压、马赛克特征、肺梗死和胸腔积液，其分别为16、25、3和22例。本研究检验确诊的37例肺动脉栓塞病症患者均经过临床治疗症状好转。结论：在肺动脉栓塞病症的临床诊断中应用128螺旋CT操作简单、安全、明显，同时在扫描检查过程中能够准确确定实际患病程度、栓塞情况及栓塞的位置和数量等，能够提高病症诊断的准确性能够也能够为临床治疗方案制定予以参考作用。

　　【Abstract】 Objective：To investigate the diagnosis of pulmonary embolism by using 128 slice spiral CT.Method：A total of 55 patients with suspected pulmonary embolism were underwent 128 slice spiral CT examination，and the results of diagnosis and treatment were discussed.Result：All patients were received 128 slice CT examination，the positive rate of diagnosis was 67.27%.A total of 81 pieces of embolus were found in 37 cases，which were found among 19 pulmonalis lobar arteria，1 pulmonary artery trunk，59 pulmonalis segmental arteria，2 pulmonalis dextra arteria.It can be summarized as the involvement of the left pulmonary artery（62.96%）and the right pulmonary artery（37.04%）.The appearance of arterial thrombosis were divided into direct signs and indirect signs by 128 slice spiral CT examination.The direct signs of arterial thrombosis were divided into attached artery walls（10 embolus），center（27 embolus），complete obstruction（9 embolus）and eccentric（35 embolus）. The direct signs of arterial thrombosis were divided into pulmonary artery pressure（16 cases），mosaic features（25 cases），pulmonary infarction（3 cases）and pleural effusion（22 cases）.37 cases of pulmonary embolism were improved by clinical treatment.Conclusion：The application of 128 slice spiral CT in the diagnosis of pulmonary embolism disease has the advantages of simple operation，safety and obvious.Meanwhile，it can accurately determine the actual prevalence and degree of embolism，embolism position and quantity in scanning process.Therefore，the application can improve the accuracy of diagnosis，and be able to develop for clinical reference treatment plan.
