This study was undertaken to determine if a duplex scanner equipped with a new 10 MHz probe could accurately evaluate microvascular anastomotic patency. The overall predictive accuracy of the duplex scanner was 90% (p less than 0.0001) with no difference noted among the three main anastomotic groups examined--acute artery, acute vein, and long-term artery. There was, however, a statistically significant difference (p less than 0.05) in the ability to interpret vessels that were patent (100%) versus those that were partially occluded (73%) or occluded (88%). It is believed that the duplex scanner has potential applications to preoperatively and intraoperatively study microvessels and postoperatively to supplement other techniques in monitoring acute and long-term anastomotic patency.
本研究旨在确定配备新型10兆赫探头的双功扫描仪能否准确评估微血管吻合的通畅情况。双功扫描仪的总体预测准确率为90%（p<0.0001），在所检查的三个主要吻合组（急性动脉、急性静脉和长期动脉）之间未发现差异。然而，在解读通畅血管（100%）与部分闭塞血管（73%）或闭塞血管（88%）的能力方面，存在统计学上的显著差异（p<0.05）。据信，双功扫描仪在术前和术中研究微血管以及术后补充其他技术监测急性和长期吻合通畅情况方面具有潜在应用价值。
