Hand-held Doppler (HHD) examination and duplex ultrasound scanning of patients with varicose veins are more accurate than clinical assessment alone. To assess how the introduction of HHD and the availability of duplex ultrasound scanning affects patient management, a retrospective review was carried out comparing the year before the introduction with the subsequent 2 years. Information was extracted from a computer database containing details of all new venous outpatients, their initial management and investigations and subsequent operations. HHD and duplex ultrasound resulted in a marked increase in secondary investigations (16% versus 41%) and fewer patients being listed directly for surgery (47% versus 29%). Operations on the long saphenous vein decreased from 84% to 76% whereas short saphenous surgery increased from 6% to 21% during this time.
手持多普勒（HHD）检查和对静脉曲张患者进行的双功超声扫描比单纯的临床评估更准确。为了评估HHD的引入和双功超声扫描的可用性如何影响患者管理，我们进行了一项回顾性研究，比较了引入前一年与随后两年的情况。信息从一个计算机数据库中提取，该数据库包含所有新静脉门诊患者的详细信息、他们的初始管理和检查以及后续手术情况。HHD和双功超声导致二次检查显著增加（16%对41%），直接列入手术名单的患者减少（47%对29%）。在此期间，大隐静脉手术从84%降至76%，而小隐静脉手术从6%增至21%。
