To report a case of endovascular stent placement to assist stable coil deployment in a symptomatic, wide-necked, partially clipped aneurysm.
A 48-year-old woman presented for endovascular treatment of a symptomatic posterior communicating artery aneurysm remnant that was surgically clipped 10 years ago. A 3.5-mm x 12-mm balloon-expandable stent was placed across the aneurysm orifice followed by complete obliteration of the remnant with coils implanted through the stent mesh. Digital subtraction angiography documented continued patency of the arterial lumen and complete obliteration of the aneurysm at 11 months.
Partial aneurysm clipping may assist or complicate secondary interventional procedures and interfere with correct visualization of the neck. Stent placement obviates the need for the balloon-assist method of coil embolization for wide-necked aneurysm remnants, acting as a mechanical barrier to hold the coils in a very unfavorable anatomy.
报告1例血管内支架置入术，以辅助在有症状的宽颈、部分夹闭动脉瘤中稳定地进行弹簧圈栓塞。
一名48岁女性因10年前接受手术夹闭的有症状的后交通动脉瘤残余灶前来接受血管内治疗。在动脉瘤开口处放置一个3.5毫米×12毫米的球囊扩张支架，随后通过支架网眼植入弹簧圈将残余灶完全闭塞。数字减影血管造影显示11个月时动脉管腔持续通畅，动脉瘤完全闭塞。
部分动脉瘤夹闭可能有助于或使二次介入手术复杂化，并干扰对瘤颈的正确观察。对于宽颈动脉瘤残余灶，支架置入避免了使用球囊辅助弹簧圈栓塞方法的必要性，在非常不利的解剖结构中起到机械屏障作用以固定弹簧圈。
