目的 :评价99mTc MAA肺灌注显像对判断急性肺栓塞溶栓继以抗凝治疗的效果及预后价值。方法 :肺栓塞患者 16例 ,治疗前、治疗后 1周、1个月和 3个月均行肺灌注显像 ,结果 :患者经溶栓继以抗凝治疗 1周后 ,临床好转 ,肺灌注显像 42 .2 %的稀疏缺损区得到不同程度的放射性填充 ;1个月及 3个月后复查 ,分别有 6 6 .9%、72 .1%的稀疏缺损区得到不同程度的放射性填充。结论 :肺灌注显像为无创性检查 ,根据稀疏缺损变化可随访观察肺栓塞的消退 ,选择用药并及时调整治疗方案。
OBJECTIVE: To evaluate the efficacy and prognostic value of 99mTc MAA lung perfusion imaging in judging acute pulmonary embolism followed by anticoagulant therapy. Methods: 16 cases of pulmonary embolism patients before treatment, 1 week after treatment, 1 month and 3 months were perfusion perfusion imaging results: patients after thrombolytic therapy followed by anticoagulation for 1 week, clinical improvement, pulmonary perfusion 42.2% of the sparse defect areas were found to have different degrees of radioactive filling. After 1 month and 3 months of follow-up, there were 66.9% and 72.1% of the sparse defects respectively. Conclusion: Lung perfusion imaging is a noninvasive method. According to the changes of sparse defects, the pulmonary embolism regression can be observed, the medication choice and timely adjustment of the treatment regimen.
