美国芝加哥消息:应用简单加压技术的超声下肢检查可成为深部静脉血栓(DVT)的快速普查试验方法。据普罗维登斯Brown大学诊断放射学副教授John J Cronan说,此项简单的非侵犯性试验可在10分钟内完成,可大大减少痛苦的静脉造影诊断DVT的次数,DVT造成90～95％的肺栓塞病例。估计每年因此病死亡人数为5万～20万。 Cronan在北美放射学会年会上说,此种非常简单的检查方法不需特殊设备,用普通的超声扫描仪并依靠加压寻找静脉血栓的位置。正常静脉在超声换能器的轻微压力下发生萎陷,但血栓存在可防止血管壁的压力,得出阳性扫描图象。Cronan在罗得岛医院对51名
Chicago, United States: Ultrasonographic lower extremity examination using simple compression techniques can be a rapid census method for deep vein thrombosis (DVT). According to John J Cronan, associate professor of diagnostic radiology at Brown University in Providence, this simple noninvasive test can be completed in less than 10 minutes, dramatically reducing the number of painful venography diagnoses of DVT that causes 90 to 95% Pulmonary embolism cases. It is estimated that the number of deaths per year is 50,000 to 200,000. Cronan at the annual meeting of the North American Society of Radiology said that this very simple examination without special equipment, using a common ultrasound scanner and rely on pressure to find the location of venous thrombosis. The normal vein collapses under slight pressure in the ultrasound transducer, but the presence of a thrombus prevents the pressure on the vessel wall, yielding a positive scan image.
