双源CT肺动脉成像在鉴别急慢性肺动脉栓塞中的诊断价值
The value of dual-source CT pulmonary angiography in identifying acute and chronic pulmonary embolism
摘要
Abstract
Objective To investigate into the value of dual-source computed tomography (DSCT) and pulmonary angiography (CTPA) in detecting acute and chronic pulmonary embolism (PE) . Methods Totally 64 patients confirmed with acute PE, who underwent CTPA examination before treatment and 15 days to 3 months after treatment, were retrospectively analyzed. This study was combined with clinical, ultrasound and laboratory examination, in order to make a comprehensive analysis of the CTPA images. Results 26 patients were confirmed with chronic PE after review. Acute or chronic PE involvement level 1, level 2, level 4 and their pulmonary artery branch number was statistically significant (P ＜ 0.05) . The direct signs of acute PE included complete and central filling defect, while in patients with chronic PE with the attached wall filling defect (P ＜ 0.001) . The incidence rate of pulmonary artery branch reduction in acute and chronic PE was different (P ＜ 0.05) . The indirect signs had no significant statistic difference between the acute and chronic PE (P＞ 0.05) . Conclusion DSCTPA is helpful in the characterization of acute and chronic PE according to direct signs, and has certain guiding significance for clinical treatment.关键词
