中文摘要

背景: 当由迂曲的经骨枕动脉(OA)供血动脉供血的硬脑膜动静脉瘘(dAVF)无法实现远端置管,且竞争性流出使Onyx从瘘口分流时,其栓塞仍然具有挑战性。我们描述了一种新型双球囊血流隔离技术。
病例描述: 一名79岁女性,患有Cognard IV型横窦dAVF,表现为认知功能下降、头痛和搏动性耳鸣。血管造影显示迂曲的经骨OA供血动脉汇聚于一个瘘口,并伴有皮质静脉反流和静脉瘤。在供血动脉置管失败后,将两根Scepter Mini球囊微导管置于单一OA蒂内。近端和远端血流阻断选择性地隔离了单支供血血管,从而允许用力注射稀释的Onyx。Onyx通过经骨供血动脉,越过瘘口,并填充引流静脉和静脉瘤,实现了完全的血管造影闭塞,且无并发症。
结论: 当远端置管不可行且竞争性流出限制Onyx渗透时,双球囊血流隔离可能有助于实现治愈性栓塞。

英文摘要

BACKGROUND: Embolization of dural arteriovenous fistulas (dAVFs) supplied by tortuous trans-osseous occipital artery (OA) feeders remains challenging when distal catheterization is not achievable and competing runoff diverts Onyx from the fistulous connection. We describe a novel dual-balloon flow-isolation technique.
CASE DESCRIPTION: A 79-year-old woman with a Cognard type IV transverse sinus dAVF presented with cognitive decline, headache, and pulsatile tinnitus. Angiography demonstrated tortuous trans-osseous OA feeders converging on a fistulous connection with cortical venous reflux and a venous varix. Following unsuccessful feeder catheterization, two Scepter Mini balloon microcatheters were positioned within a single OA pedicle. Proximal and distal flow arrest selectively isolated a single feeding vessel, permitting forceful injection of diluted Onyx. Onyx traversed the trans-osseous feeders, crossed the fistulous connection, and filled the draining vein and venous varix, achieving complete angiographic obliteration without complications.
CONCLUSIONS: Dual-balloon flow isolation may facilitate curative embolization when distal catheterization is not feasible and competing runoff limits Onyx penetration.
