To describe a novel technique to facilitate Tube Extender implantation.
Two Tube Extender implantations were performed on 2 eyes of 2 patients.
Before implanting the Tube Extender onto the cut tube of the glaucoma drainage device, a 30-G cannula, coated with viscoelastic, is threaded through the distal end of the extender and emerges from the proximal end. The cannula, with the extender laced over it, is then inserted into the cut tube, and the surgeon slides the Tube Extender down the cannula for insertion onto the cut tube.
Retraction of the glaucoma drainage device from the anterior chamber occurs for various reasons, often the growth of the globe in pediatric patients. Tube Extenders can be implanted to lengthen the glaucoma drainage device to reenter the anterior chamber. However, the surgical technique can often be technically difficult to perform due to the flexibility of the glaucoma drainage device tube. We present a novel technique for Tube Extender implantation that makes the procedure easier to perform.
描述一种便于植入引流管延长器的新技术。
对2例患者的2只眼睛进行了2次引流管延长器植入手术。
在将引流管延长器植入青光眼引流装置的切断管之前，将涂有粘弹性物质的30G套管穿过延长器的远端并从近端穿出。然后将套有延长器的套管插入切断管，外科医生将引流管延长器沿套管向下滑动以插入切断管。
青光眼引流装置从前房退缩的原因多种多样，在儿科患者中通常是眼球的生长。可以植入引流管延长器来延长青光眼引流装置以重新进入前房。然而，由于青光眼引流装置管的柔韧性，手术技术往往在操作上具有挑战性。我们提出了一种用于引流管延长器植入的新技术，使该手术更容易实施。
