The sine qua non to best ensure viability of any autogenous tissues used for breast reconstruction is to maximize the appropriate circulatory pattern to that tissue. This overview of tools used in this regard, all based on the physical principles of the Doppler effect, compares the role today of acoustic Doppler sonography, color duplex ultrasound, and laser Doppler flowmetry for perforator identification and flap monitoring. The audible Doppler has recognized limitations, but remains the simplest and most universally available device to assist in this purpose. Laser Doppler flowmetry provides a reasonable system for both intraoperative and post-procedure objective monitoring of the chosen tissue transfer.
确保用于乳房重建的任何自体组织存活的必要条件是最大限度地提高该组织的适当循环模式。本文综述了在这方面使用的工具，这些工具都是基于多普勒效应的物理原理，比较了声学多普勒超声、彩色双功能超声和激光多普勒血流仪在穿支血管识别和皮瓣监测中的作用。可听多普勒存在公认的局限性，但仍然是最简单和最普遍可用的设备，可用于辅助这一目的。激光多普勒血流仪为术中及术后选择的组织转移的客观监测提供了一个合理的系统。
