摘　　要：为了解肺栓塞(PE)患者下肢深静脉血栓(DVT)的情况,对71例PE患者行99Tcm-MAA下肢深静脉显像。结果表明,71例PE患者中有55例(77.5%)可检测到下肢DVT;在36例伴有下肢DVT症状的PE患者中,32例(88.9%)可检测到DVT,而在35例无下肢DVT症状的PE患者中有23例(65.7%)可检测到DVT;无下肢症状患者DVT多位于远端静脉,有下肢症状患者DVT多累及到近端静脉。因此,99Tcm-MAA下肢深静脉显像对有下肢症状和无下肢症状的PE患者的DVT检出率均较高,应作为肺灌注显像前的常规检查手段。To study the prevalence of DVT in patients with pulmonary embolism（PE） ,^99Tc^m-MAA lower extremity vein scan is performed in 71 PE patients. The results show that 55 of 71 PE patients are found with DVT, and 32 cases are found with DVT in 36 PE patients with symptoms of DVT, while in 35 PE patients without symptoms of DVT,23 cases are found with DVT. Asymptomatic DVT is often found in distal veins, while symptomatic DVT in proximal veins. ^99Tc^m-MAA lower extremity vein scan could detect both asymptomatic DVT and symptomatic DVT ,so it should be used as a routine examination in PE patients before lung perfusion scan is done.
