Abstract: Objective: This study evaluated percutaneous lymphatic contrast-enhanced ultrasound (CEUS) for preoperative localization in preparation for lymphovenous anastomosis (LVA) microsurgery. Methods: Fourteen healthy volunteers and 14 patients with lower limb lymphoedema were studied. SonoVue® (Bracco, Milan, Italy) was used to measure lymphatic vessel diameters and depths in the dorsal foot, ankle, and lower leg of the subjects. In the lymphoedema patients, lymphatic vessels were observed for continuity, distortion, dilation, interruption, and other abnormalities. On the basis of the CEUS images, the lower limb lymphatic vessels were categorized as normal, dilated, contracted, or sclerotic. In the lymphoedema patients, the locations of lymphatic vessels with good visibility were marked on the skin, and the accuracy of preoperative localization was evaluated based on the basis of surgical results. The data were analysed using IBM SPSS Statistics27.0 (IBM Corp., Armonk, NY, USA). Continuous data are expressed as the means ± standard deviations and were compared using paired t-tests, with P
