Safety and long-term efficacy of endovascular treatment of small posterior communicating artery aneurysms by coiling with or without stent: A single center retrospective study

Objectives

Endovascular stents have been widely used in intracranial aneurysm embolization. In this work, we compared the safety and long-term efficacy of stent-assisted coiling with those of conventional coiling for small posterior communicating artery aneurysms, aiming at a better understanding of the related safety and efficacy profiles.

Methods

Between January 2008 and December 2011, 114 small PcomA aneurysms (defined as 3 mm ≤ maximum diameter < 10 mm in this study) in 108 patients were treated by endovascular treatment in our department. Patient demographics, aneurysm characteristics, angiographic results (initial and follow-up), and procedural complications were assessed.

Results

Embolization was successfully performed in all the patients. Complications occurred in 7.4% of patients in both groups. There was no associated mortality. Based on initial post-procedural angiography, the rate of complete aneurysm occlusion, neck remnant and residual sac in the stented group were 37.9%, 24.1%, and 37.9%, while in the conventional group the figures were 42.9%, 48.2%, and 8.9%, respectively. The initial angiographic results were significantly better in the conventional group, compared with the stented group (P = 0.038). The follow-up results showed that the rate of improvement in the stented group was significantly higher (53.3% vs. 14.0%; P < 0.001) and the recurrence rate was significantly lower than that in the conventional group (4.4% vs. 3.02%; P = 0.001).

Conclusion

Compared with conventional coiling, stent-assisted coiling of the small posterior communicating artery aneurysms does not increase the risk. Stents bear an advantage in reducing the recurrence rate, increasing progressive occlusion rate, and improving long-term prognosis in endovascular treatment of intracranial aneurysms.

血管内治疗低级别破裂前交通动脉动脉瘤合并颅内血肿的临床分析

目的探讨血管内治疗低级别(Hunt-Hess分级Ⅰ~Ⅲ级)破裂前交通动脉(ACoA)动脉瘤合并颅内血肿的安全性及有效性。方法回顾性分析2015年3月至2020年3月于南京医科大学第一附属医院介入放射科接受血管内治疗的42例低级别ACoA动脉瘤合并颅内血肿患者的临床及影像学资料。42例ACoA动脉瘤采用单纯弹簧圈栓塞32例,支架辅助弹簧圈栓塞10例;颅内血肿均采取保守治疗。术后影像学随访采用数字减影血管造影(DSA)或CT血管成像,并采用Raymond分级标准评估动脉瘤的栓塞程度;临床随访采用格拉斯哥预后评级(GOS)(出院时)和改良Rankin量表评分(mRS)评估(6个月时)。结果42例ACoA动脉瘤栓塞术后即刻DSA显示,动脉瘤完全闭塞(RaymondⅠ级)21例(50.0%),近全闭塞(RaymondⅡ级)20例(47.6%),部分闭塞(RaymondⅢ级)1例(2.4%)。总体并发症的发生率为9.5%(4/42),包括1例支架辅助术后血栓栓塞性事件及3例迟发性脑缺血事件。术后复查头颅CT显示血肿均较前吸收,出院时GOSⅤ级34例(80.9%),Ⅳ级7例(16.7%),Ⅲ级1例(2.4%),无死亡患者。42例患者中,36例(85.7%)接受DSA复查,复查的中位时间为6.5个月(4~12个月),其中RaymondⅠ级32例(88.9%),Ⅱ级4例(11.1%)。1例动脉瘤复发,予以支架辅助弹簧圈再次栓塞治疗。术后6个月的临床随访显示,患者的预后良好(mRS 0~2分)率为97.6%(41/42)。结论血管内治疗低级别ACoA动脉瘤合并颅内血肿安全有效,支架辅助栓塞并未增加并发症的发生风险,血肿经过栓塞后可吸收,但需大样本数据及长期随访进一步证实。

Waffle-Cone Technique Using Solitaire AB Stent

The waffle-cone technique is a modified stent application technique, which involves protrusion of the distal portion of a stent into an aneurysm fundus to provide neck support for subsequent coiling. The authors report two cases of wide necked basilar bifurcation aneurysms, which were not amenable to stent assisted coiling, that were treated using the waffle-cone technique with a Solitaire AB stent. A 58-year-old woman presented with severe headache. Brain CT showed subarachnoid hemorrhage and angiography demonstrated a ruptured giant basilar bifurcation aneurysm with broad neck, which was treated with a Solitaire AB stent and coils using the waffle-cone technique. The second case involved an 81-year-old man, who presented with dizziness caused by brain stem infarction. Angiography also demonstrated a large basilar bifurcation unruptured aneurysm with broad neck. Solitaire AB stent deployment using the waffle-cone technique, followed by coiling resulted in near complete obliteration of aneurysm. The waffle-cone technique with a Solitaire AB stent can be a useful alternative to conventional stent application when it is difficult to catheterize bilateral posterior cerebral arteries in patients with a wide-necked basilar bifurcation aneurysm.     

Retrograde stenting through anterior communicating artery in coil embolization of the posterior communicating artery aneurysm: contralateral approach

During coil embolization of wide-necked posterior communicating artery (PcomA) aneurysms, stent assistance is sometimes limited if PcomA is acutely angled at its origins from saccular neck. Herein, we present two instances where retrograde stenting was used for coil embolization of PcomA aneurysms. Both procedures involved a contralateral approach via anterior communicating artery (AcomA). To achieve this, the stent-delivery microcatheter was inserted retrograde from contralateral to ipsilateral internal carotid artery (ICA) across AcomA, arriving at ipsilateral PcomA. A separate microcatheter, passed through ipsilateral ICA, was then used to select the aneurysm sac for coil delivery. Coil embolization ultimately took place under protection of a horizontally placed stent extending from PcomA to terminal ICA. Each aneurysm was properly coiled and occluded, without procedural complications. This stenting technique is a reasonable option, offering a means of strategic coil embolization in wide-necked PcomA aneurysms and providing complete neck coverage through contralateral access.
