There are few studies on flow diverters with diameters >5 mm. We present our preliminary experience with the 5.5-8 mm Derivo Embolization Device (DED) implants for the treatment of cerebral aneurysms.
A consecutive series of 26 patients (median age: 60 years) treated for 32 aneurysms in 26 procedures was retrospectively analyzed for procedural characteristics, complications, and mid-term angiographic results.
The median aneurysm size was 10.5 mm, 2 of 30 (6%) aneurysms were ruptured and 9 (28%) had a fusiform or dissecting morphology. DED implantation was performed in the internal carotid artery in 18 of 26 (69%) procedures and in the vertebrobasilar artery in 8 (31%). Device deployment failed in 1 (4%) procedure. The 7 and 8 mm implants were successfully deployed in 5 cases. Additional balloon angioplasty or stent implantation was performed in 3 (12%) cases to improve wall apposition. Complications included 1 (4%) major stroke and 2 (8%) minor strokes. Angiographic follow up at a mean of 6 months showed complete occlusion in 8 of30 (27%) aneurysms and favorable occlusion in 14 (47%).
The use of large diameter DEDs was safe and feasible. The mid-term occlusion rates are acceptable considering the complex subset of aneurysms studied. Further studies are warranted to define the indications for large-diameter DEDs and to evaluate their long-term efficacy.
关于直径大于5毫米的血流导向装置的研究较少。我们展示了使用5.5 - 8毫米Derivo栓塞装置（DED）植入治疗脑动脉瘤的初步经验。
回顾性分析连续26例患者（中位年龄：60岁），在26次手术中治疗32个动脉瘤，分析手术特征、并发症和中期血管造影结果。
动脉瘤中位大小为10.5毫米，30个动脉瘤中有2个（6%）破裂，9个（28%）呈梭形或夹层形态。26次手术中有18次（69%）在颈内动脉进行DED植入，8次（31%）在椎基底动脉进行。1次（4%）手术中装置部署失败。7毫米和8毫米的植入物在5例中成功部署。3例（12%）进行了额外的球囊血管成形术或支架植入以改善贴壁情况。并发症包括1例（4%）严重卒中，2例（8%）轻度卒中。平均6个月的血管造影随访显示，30个动脉瘤中有8个（27%）完全闭塞，14个（47%）闭塞良好。
使用大直径DED是安全可行的。考虑到所研究的动脉瘤复杂亚组，中期闭塞率是可以接受的。有必要进一步研究以明确大直径DED的适应证并评估其长期疗效。
