The aim of this study was to report the "Single Port Technique" for perfluorocarbon liquid-silicone oil (SO) exchange for the management of giant retinal tear detachments.
The previously reported techniques of direct perfluorocarbon liquid-SO exchange used two ports to achieve the influx and outflux of fluid. The term "Single Port" refers to the use of only one port as the exclusive port for the inflow of SO and the outflow of fluid meniscus and perfluorocarbon liquid, performed alternately. This technique is proposed, with illustrated instructions and a surgical video.
The newly proposed "Single Port Technique" offers a straightforward step using a switch between active aspiration by the vitreous cutter and active SO injection through a single port without the need for assistance. This method has been performed by the authors on 29 patients, including 22 giant retinal tear detachment patients and 7 patients with rhegmatogenous retinal detachment caused by dialysis, and it has demonstrated its simplicity and reliability for use with only standard vitrectomy tools and machine settings.
The single-port technique for perfluorocarbon liquid-SO exchange for the management of giant retinal tear detachment and rhegmatogenous retinal detachment caused by dialysis has been tried and tested, and it is a valuable tool that can be easily used by any vitreoretinal surgeon.
本研究的目的是报告用于全氟碳液体 - 硅油（SO）交换以治疗巨大视网膜裂孔性视网膜脱离的“单端口技术”。
先前报道的直接全氟碳液体 - SO交换技术使用两个端口来实现液体的流入和流出。“单端口”一词是指仅使用一个端口作为SO流入以及液体弯月面和全氟碳液体流出的唯一端口，交替进行。本文提出了该技术，并配有说明指导和手术视频。
新提出的“单端口技术”提供了一个简单的步骤，通过玻璃体切割器的主动抽吸和通过单个端口的主动SO注入之间的切换，无需辅助。作者已对29例患者实施了该方法，其中包括22例巨大视网膜裂孔性视网膜脱离患者和7例因视网膜脱离引起的孔源性视网膜脱离患者，并且已证明其仅使用标准玻璃体切除工具和机器设置时的简单性和可靠性。
用于治疗巨大视网膜裂孔性视网膜脱离和因视网膜脱离引起的孔源性视网膜脱离的全氟碳液体 - SO交换单端口技术已经过试验和测试，是一种任何玻璃体视网膜外科医生都可以轻松使用的有价值工具。
