A choroidal detachment may form during pars plana vitrectomy when the infusion line is partially disinserted and fluid is infused into the choroid or suprachoroidal space instead of into the vitreous cavity. We describe a new surgical technique that was used successfully in 4 patients who developed intraoperative choroidal detachments during 23-gauge vitrectomy after the infusion cannula was accidentally partially disinserted. During surgery, the infusion line was disconnected from the partially disinserted cannula and was reconnected to another fully inserted cannula. After resuming infusion into the vitreous cavity, the partially disinserted 23-gauge cannula was left in position and was used to immediately drain the choroidal detachment that had formed intraoperatively. In all 4 patients, the surgery then proceeded without complication.
当灌注管部分脱出，液体注入脉络膜或脉络膜上腔而非玻璃体腔时，在扁平部玻璃体切除术中可能会形成脉络膜脱离。我们描述了一种新的手术技术，该技术成功应用于4例患者，这些患者在23G玻璃体切除术中因灌注套管意外部分脱出而发生术中脉络膜脱离。手术过程中，将灌注管与部分脱出的套管断开，重新连接到另一根完全插入的套管上。在恢复向玻璃体腔灌注后，将部分脱出的23G套管留在原位，用于立即引流术中形成的脉络膜脱离。所有4例患者随后的手术均未出现并发症。
