目的 探讨下肢静脉病变与肺栓塞 (PE)发病之间的关系。方法 对 5 0例正常对照者和 2 0 0例临床高度怀疑PE和下肢静脉病变的患者 ,行99Tcm 大颗粒聚合白蛋白 (MAA)和99Tcm 葡聚糖酯 (GP)双下肢静脉显像和肺灌注 /通气显像 ,其中 15例进行了肺动脉造影。结果 对照组下肢静脉显像和肺灌注 /通气显像均显示正常 ,2 0 0例患者肺灌注 /通气显像示 :175例为多发性PE ,2 5例正常。175例PE患者中 12 8例有下肢静脉病变 ,占 73.14% (12 8/ 175例 ) ,其中下肢深静脉血栓 (DVT) 119例 ,占 6 8.0 0 % (119/ 175例 ) ;2 5例非PE者均有下肢静脉病变。 15 3例下肢静脉病变者中检出PE 12 8例 ,占 83.6 6 % (12 8/ 15 3例 )。下肢DVT 119例 ,其中由髂、股静脉血栓引发PE者 10 1例 ,占 84.87% (10 1/119例 )。结论 双下肢静脉显像与肺灌注 /通气显像联合应用 ,有助于PE及其病因的诊断
Objective To investigate the relationship between venous leg disease and pulmonary embolism (PE). Methods Fifty patients with normal controls and 200 patients with clinically suspected PE and lower extremity venous lesions underwent 99Tcm MAA and 99Tcm dextran ester (GP) Perfusion / ventilation imaging, of which 15 cases had pulmonary angiography. Results In the control group, venous perfusion of the lower extremities and lung perfusion / ventilation imaging were all normal. Lung perfusion / ventilation imaging in 200 patients showed 175 cases of multiple PE and 25 cases of normal. Of the 175 patients with PE, 12 8 had lower extremity venous lesions, accounting for 73.14% (12 of 175 cases), including 119 cases of deep venous thrombosis (DVT), accounting for 6 8.0% (119/175 cases); 25 Non-PE who have lower extremity venous disease. Fifty-eight cases were detected in 15 3 cases of venous lower extremity lesions, accounting for 83.6% (12 out of 8/15 cases). There were 119 cases of lower extremity DVT, of which 101 cases were caused by iliac and femoral vein thrombosis, accounting for 84.87% (10 1/119 cases). Conclusions The combination of venous imaging of both lower extremities and lung perfusion / ventilation imaging is helpful for the diagnosis of PE and its etiology
