The need for a reliable noninvasive method to detect deep venous thrombosis (DVT) is apparent from its prevalence, the fallibility of its clinical diagnosis, and the several drawbacks of phlebography. Experience with phleborheography (a plethysmographic technique for detecting DVT) over three years is presented. Phleborheography (PRG) is found to have an overall accuracy of 93% compared to phlebography. It is recommended that treatment decisions can be based on unequivocal PRG results, and PRG should be used to screen high risk patients. The medical, economic, and social benefits of PRG are described.
从深静脉血栓形成(DVT)的患病率、临床诊断的易错性以及静脉造影的若干缺点来看,对一种可靠的非侵入性检测深静脉血栓形成的方法的需求是显而易见的。本文介绍了三年来静脉血流图(一种检测深静脉血栓形成的体积描记技术)的应用经验。与静脉造影相比,发现静脉血流图(PRG)的总体准确率为93%。建议治疗决策可基于明确的PRG结果,并且PRG应用于筛查高危患者。文中描述了PRG的医学、经济和社会效益。
