Approximately 500,000 cases of pulmonary embolism appear each year in the United States, with most having clots that originated in the deep veins of the lower extremities. Since the clinical diagnosis of deep venous thrombosis (DVT) is accurate only half the time, a safe method that affords immediate and definitive diagnosis of DVT is urgently needed. One diagnostic technique now available is phleborheography (PRG). We examined 1,076 patients (2,152 limbs) during the period of 1976 to 1979. By performing PRG before hospital admission, 392 patients who had negative study results were not hospitalized, resulting in an estimated savings of +960,400 and avoiding both the hazardous treatment and the stigma associated with a diagnosis of DVT. After one to three years of follow-up in 593 patients (1,186 limbs) who had had negative results from PRG, only three (0.5%) have shown evidence of postphlebitic swelling and one (0.2%) has had pulmonary embolus.
在美国，每年大约出现50万例肺栓塞病例，其中大多数血栓起源于下肢深静脉。由于深静脉血栓形成（DVT）的临床诊断仅有一半时间是准确的，因此迫切需要一种能够立即做出DVT明确诊断的安全方法。目前可用的一种诊断技术是静脉血流图（PRG）。在1976年至1979年期间，我们检查了1076例患者（2152条肢体）。通过在入院前进行PRG，392例检查结果为阴性的患者未住院，估计节省了960400美元，同时避免了危险的治疗以及与DVT诊断相关的污名。在对593例（1186条肢体）PRG结果为阴性的患者进行一至三年的随访后，只有3例（0.5%）出现了血栓后肿胀的迹象，1例（0.2%）发生了肺栓塞。
