IntroductionWe sought to examine midterm results and remodeling effect of false-lumen occlusion treatment using AFX VELA in case of chronic dissection repair.Material and MethodsFrom June 2019 to May 2022, we performed false lumen occlusion treatment using a modified Candy-Plug technique with AFX VELA on 8 chronic aortic dissection patients with a patent false lumen. We collected operative data, short-term clinical outcomes, mid-term clinical outcomes and imaging test results. We conducted follow-up examinations at postoperative, 6-month and 1-, 2- and 3-year intervals, including contrast-enhanced computed tomography to evaluate the diameter, false lumen thrombosis and any events.ResultsThe average time from the symptom onset to the thoracic endovascular repair was 81.5 (35-155) months. The aorta showed aneurysmal dilation with an average maximum short-axis diameter of 58.9 (41-91) mm. Two cases needed emergency surgery due to rupture and impending rupture. There were no postoperative deaths. Complete thrombosis within the false lumen was achieved in 6 cases (75%), but 2 cases had incomplete thrombosis, requiring additional treatment. The mean maximum diameter showed a significant decrease at 6 months, 1 year and 2 years postoperatively compared to preoperative measurements ( P < .05).ConclusionWe showed the results of false lumen occlusion treatment using the AFX VELA cuff. We observed favorable clinical outcomes and remodeling effects. While the long-term durability and efficacy of this technique in aortic remodeling will need to be monitored with further observation, the use of this cuff is considered a reliable approach to false lumen occlusion treatment.

AFX VELATM 糖果塞技术假腔闭塞治疗慢性主动脉夹层的效果

介绍我们试图检查在慢性夹层修复中使用 AFX VELA 假腔闭塞治疗的中期结果和重塑效果。材料和方法从 2019 年 6 月至 2022 年 5 月，我们使用改良的 Candy-Plug 技术和 AFX VELA 进行假腔闭塞治疗对 8 名假腔明显的慢性主动脉夹层患者进行了研究。我们收集了手术数据、短期临床结果、中期临床结果和影像学检查结果。我们在术后、6个月以及1年、2年和3年的时间间隔进行随访检查，包括增强计算机断层扫描以评估直径、假腔血栓形成和任何事件。结果从症状出现到出现症状的平均时间胸部血管内修复术为81.5（35-155）个月。主动脉呈动脉瘤样扩张，平均最大短轴直径为 58.9 (41-91) mm。2例因破裂及即将破裂需要紧急手术。无术后死亡。6例（75%）假腔内血栓完全形成，2例血栓不完全，需要额外治疗。与术前测量相比，术后 6 个月、1 年和 2 年平均最大直径显着减小 ( P < .05)。结论我们展示了使用 AFX VELA 袖带进行假腔闭塞治疗的结果。我们观察到良好的临床结果和重塑效果。虽然该技术在主动脉重塑中的长期耐久性和功效需要进一步观察来监测，但使用该袖带被认为是假腔闭塞治疗的可靠方法。
