Keyword:  彩超下肢静脉应用;
Abstract: 下肢静脉疾病是常见病、多发病,主要包括下肢静脉瓣膜病和下肢深静脉血栓形成。下肢深静脉血栓形成后遗症所致的瓣膜功能不全以及并发肺栓塞可威胁病人生命安全,因而受到临床的重视。现将彩超在下肢静脉疾病中的应用体会介绍如下。1检查内容与注意事项①观察静脉变异、内膜和管腔内回声情况。②探头横切加压探查。③观察静脉腔内是否有自发性血流信号以及血流信号的充盈情况。④观察静脉返流情况。⑤正常瓣膜回声较弱,常不被超声显示瓣膜窦处是血检的好发部位,应仔细观察。⑥有些深部的小腿静脉难以被二维图像清晰显示,可依靠彩色血流显像来证实它们的开放情况。⑦正常小腿胫、腓静脉的自发性血流信号可不存在,但在人工挤压足部或远端肢体后
