Abstract

Background: This study aimed to quantify the blood flow of free flaps and compare the blood flow of small vessel (<0.8 mm) and larger vessel (>0.8 mm) anastomosed free flaps.

Methods: This retrospective study included patients treated successfully with a perforator free flap in the lower extremity between June 2015 and March 2017. A color duplex ultrasound system measured the flow volume through the pedicle by analyzing the mean flow peak velocity, flow volume, and flow volume per 100 g of the flap.

Results: A total of 69 patients were enrolled in this study. There was no statistical difference in peak velocity between the small vessel anastomosed free flap (25.2 ± 5.6) and larger vessel anastomosed free flap (26.5 ± 5.4). Flow volume (6.8 ± 4.2 vs. 6.3 ± 3.6) and flow volume/100 g (3.6 ± 3.9 vs. 6.2 ± 6.9) also did not show significant differences.

Conclusion: Small vessel (<0.8 mm) free flaps showed similar flow velocity and flow volume to larger vessel (>0.8 mm) anastomosed free flaps. Blood flow to the small vessel anastomosed free flap was sufficient despite its small vessel size.

小血管（0.8mm以下）与大血管（0.8mmm以上）吻合游离皮瓣的比较研究；超级显微外科手术能为游离皮瓣提供足够的血液流动吗？

背景：本研究旨在量化游离皮瓣的血流量，并比较小血管（0.8mm）吻合的游离皮瓣的血流。方法：一项回顾性研究纳入了2015年6月至2017年3月期间接受下肢无穿支皮瓣治疗的患者。彩色双相超声系统通过分析平均流量峰值速度、流量和每100g皮瓣的流量来测量通过椎弓根的流量。结果：本研究共纳入69例患者。小血管吻合游离皮瓣（25.2±5.6）和大血管吻合游离瓣（26.5±5.4）的峰值流速无统计学差异。流量（6.8±4.2对6.3±3.6）和流量/100g（3.6±3.9对6.2±6.9）也无显著差异。结论：小血管（0.8mm）吻合游离皮瓣。血管吻合的小血管游离皮瓣的血流量是足够的，尽管它的血管很小。

期刊介绍： The Journal of Reconstructive Microsurgery is a peer-reviewed, indexed journal that provides an international forum for the publication of articles focusing on reconstructive microsurgery and complex reconstructive surgery. The journal was originally established in 1984 for the microsurgical community to publish and share academic papers. The Journal of Reconstructive Microsurgery provides the latest in original research spanning basic laboratory, translational, and clinical investigations. Review papers cover current topics in complex reconstruction and microsurgery. In addition, special sections discuss new technologies, innovations, materials, and significant problem cases. The journal welcomes controversial topics, editorial comments, book reviews, and letters to the Editor, in order to complete the balanced spectrum of information available in the Journal of Reconstructive Microsurgery. All articles undergo stringent peer review by international experts in the specialty.
