Unidirectional Doppler is a common diagnostic tool by the Reconstructive Microsurgeons; however, it may generate false signals and surely provides less imaging data as compared to duplex ultrasonography. We have reviewed the use of Portable Duplex Ultrasonography (PDU) in 16 patients who underwent complex soft-tissue/bone reconstruction, aiming to determine its role in the design and management of free tissue transfer. According to our data, there were modifications either of the surgical plan and/or of patient's management, based on PDU findings, in 10 out of 16 patients (62.5%). The use of ultrasound directed to subtle modifications in three patients (19%), but to significant changes of the surgical plan in four patients (25%). Also, the use of ultrasound improved significantly the postoperative management in three patients (19%). Thus, significant impact of PDU in patient's treatment was recorded in 44% of cases. Portable ultrasound represents generally available method for preoperative, intraoperative, and postoperative diagnosis and decision-making in free tissue transfer, hence could replace in the near future the unidirectional Doppler in the hands of Microsurgeons.
单向多普勒是重建显微外科医生常用的诊断工具；然而，与双功能超声相比，它可能会产生错误的信号，并且提供的成像数据肯定更少。我们回顾了便携式双功能超声（PDU）在 16 例接受复杂软组织/骨重建的患者中的应用，旨在确定其在游离组织转移的设计和管理中的作用。根据我们的数据，在 16 例患者中有 10 例（62.5%）基于 PDU 发现对手术计划和/或患者管理进行了修改。在 3 例患者（19%）中，超声用于指导细微的手术计划修改，而在 4 例患者（25%）中，超声用于显著改变手术计划。此外，超声的使用显著改善了 3 例患者（19%）的术后管理。因此，PDU 在患者治疗中的显著影响记录在 44%的病例中。便携式超声是游离组织转移术前、术中和术后诊断和决策的常用方法，因此在不久的将来可能会取代显微外科医生手中的单向多普勒。
