摘要
目的探讨双源CT肺动脉成像在急慢性肺动脉栓塞鉴别中的诊断价值。方法回顾性分析64例确诊急性肺动脉栓塞患者治疗前、治疗后15 d—3个月CT肺动脉成像资料,结合临床、超声及实验室检查对图像进行综合分析。结果26例患者复查确诊为慢性肺动脉栓塞,急慢性肺动脉栓塞累及1级、2级、4级肺动脉分支数差异有统计学意义(P<0.05),急性肺动脉栓塞患者中充盈缺损形态以完全和中心充盈缺损为主,慢性肺动脉栓塞患者中以附壁充盈缺损为主(P<0.001);急慢性肺动脉栓塞肺动脉分支减少出现率差异有统计学意义(P<0.05);间接征象急慢性肺动脉栓塞对比分析差异无统计学意义(P>0.05)。结论根据直接征象双源CT肺血管成像能较准确地判定急慢性肺动脉栓塞,对临床治疗具有一定指导意义。
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.
