To assess the utility of the Thiel arterial model in microsurgical research, we compared interrupted horizontal mattress (HM) sutures to simple interrupted (SI) sutures in human vessels.
A microsurgical set-up using an operating microscope and Thiel-embalmed arteries was used to practice ten SI and HM anastomoses. Vessel patency, leak and stricture were evaluated using angiography, and vessel wall architecture was evaluated using light microscopy and scanning electron microscopy (SEM). The technique speed was also assessed.
We have successfully evaluated all outcomes. All anastomoses were patent. The stricture rate was higher with HM than with SI (60% vs. 35% surface area reduction). Three minor leaks occurred with HM sutures versus one with SI sutures. Edges were evenly everted without any intimal flaps with HM compared to SI. The anastomoses were performed faster using HM than SI sutures (7:58 min vs. 12:41 min, respectively).
This is the first study to evaluate the feasibility of a Thiel-embalmed artery model for research purposes. The HM microvascular suture is a promising technique that requires further in vivo validation.
为了评估 Thiel 动脉模型在显微外科研究中的实用性，我们将人体血管中的间断水平褥式缝线（HM）与单纯间断缝线（SI）进行了比较。
使用手术显微镜和 Thiel 防腐动脉建立了一个显微外科设置，用于练习 10 个 SI 和 HM 吻合术。通过血管造影评估血管通畅性、漏血和狭窄，通过光镜和扫描电子显微镜（SEM）评估血管壁结构。还评估了技术速度。
我们成功评估了所有结果。所有吻合口均通畅。HM 的狭窄率高于 SI（60% vs. 35% 面积减少）。HM 缝线有 3 个小漏，而 SI 缝线有 1 个。与 SI 相比，HM 的边缘均匀外翻，没有任何内膜瓣。HM 缝线的吻合速度快于 SI 缝线（分别为 7:58 分钟和 12:41 分钟）。
这是第一项评估 Thiel 防腐动脉模型用于研究目的的可行性的研究。HM 微血管缝线是一种很有前途的技术，需要进一步的体内验证。
