64排128层螺旋CT肺动脉CTA对肺动脉栓塞的诊断价值探讨

Diagnostic value of 64 row 128 slice spiral CT pulmonary artery CTA in pulmonary embolism

目的:分析螺旋CT血管造影(CTA)诊断肺动脉栓塞的临床效果。方法:选取我院收治的35例肺动脉栓塞患者,纳入时间为2015年12月—2017年12月。利用64排128层螺旋CT扫描仪,对患者进行常规扫描和CTA增强扫描,观察诊断结果,分析影像学特征。结果:35例患者中,CTA诊断阳性率为94.3%,高于CT诊断的68.6%,差异有统计学意义(P <0.05)。肺动脉栓塞位于左肺动脉11例、右肺动脉14例、叶动脉6例、段动脉4例;栓塞类型:偏心性13例、中心性10例、附壁性8例、完全性4例。结论:CTA诊断肺动脉栓塞效果优于常规CT,具有安全便捷的优势,可以作为临床治疗和预后评估的依据。

Objective To analyze the clinical effect of spiral CT angiography(CTA) in the diagnosis of pulmonary embolism. Methods 35 patients with pulmonary embolism admitted in our hospital were selected from December 2015 to December 2017. Using 64 row 128 slice spiral CT scanner, routine scanning and CTA enhanced scanning were performed to observe the diagnostic results and analyze the imaging features. Results In 35 patients, the positive rate of CTA diagnosis was 94.3%, higher than that of CT diagnosis(68.6%), and the difference was statistically significant(P < 0.05). Pulmonary embolism was located in 11 cases of left pulmonary artery, 14 cases of right pulmonary artery, 6 cases of leaf artery and 4 cases of segmental artery. The types of embolism were 13 cases of eccentric, 10 Central, 8 wall attachment, and 4 complete. Conclusion CTA is superior to conventional CT in the diagnosis of pulmonary embolism. It has advantages of safety and convenience, and can be used as a basis for clinical treatment and prognosis evaluation.
