Microsurgery has made great contributions to the advancement of surgery. In parallel with the developments in microsurgery, various techniques have been developed to perfect the technique. Microvascular anastomotic coupler device (MACD) is one of these techniques. The aim of the study was to evaluate the effectiveness of anastomoses created by using hand-sewn microsurgery (HSM) and MACD.
Twenty male Sprague-Dawley rats weighing 250 to 300 g were divided into 2 groups randomly. Arteriovenous shunt was performed between carotid artery and internal jugular vein with the principles of HSM in the first group (n=10) and by using the 1-mm anastomotic microvascular device in the second group (n=10). Groups were evaluated for anastomose time, success of anastomosis, thrombosis formation, color Doppler ultrasonography, and histopathological features.
Anastomotic time was faster with the coupler device compared with HSM technique. Flow rates were found significantly higher in the MACD group. Endothelialization and wall integrity rates were better in MACD group.
Microvascular anastomotic coupler device is faster than HSM. High quality and durability of vascularization, insignificant foreign body reactions are histopathological advantages of MACD.
显微外科技术为外科手术的发展做出了巨大贡献。随着显微外科技术的发展，各种技术也得到了发展，以完善该技术。微血管吻合器（MACD）就是其中之一。本研究旨在评估使用手工吻合（HSM）和 MACD 进行吻合的效果。
将 250-300 克雄性 Sprague-Dawley 大鼠 20 只随机分为 2 组。第一组（n=10）按 HSM 的原则在颈总动脉和颈内静脉之间进行动静脉分流，第二组（n=10）使用 1mm 吻合微血管装置。评估两组的吻合时间、吻合成功率、血栓形成、彩色多普勒超声和组织病理学特征。
与 HSM 技术相比，使用吻合器装置的吻合时间更快。MAC 组的血流速度明显更高。MAC 组的血管化内皮化和壁完整性率更好。
微血管吻合器比 HSM 更快。MAC 具有更快的吻合时间、更好的血管化质量和耐久性、较小的异物反应等组织病理学优势。
