Endovascular treatment of giant and large intracranial aneurysms using the neuroform stent-assisted coil placement

BACKGROUND: Giant and large intracranial aneurysms represent enormous therapeutic challenges for neurosurgeons as well as for endovascular therapists. Since they may involve entire vessels or be irregular in shape, the rate of complete obliteration with GDCs is low and the incidence of recanalization is very high. So the technique of stent-assisted coil placement is designed to treat aneurysms. OBJECTIVE: This study was to evaluate the endovascular treatment of giant and large intracranial aneurysms using neuroform stent-assisted coil placement. METHODS: Thirty-six patients harboring giant or large intracranial aneurysms were treated by using the neuroform stent-assisted coil placement. It was parallel to navigate the neuroform stent and the microcatheter. RESULTS: Thirty-five of neuroform stents were easily delivered and deployed at the desired location. Of the 35 aneurysms successfully stented, all the aneurysms were occluded with stent-assisted coiling. Twenty-nine were totally occluded, and six aneurysms were with neck remnants. There was no complication related to the procedure except for the asymptomatic migration of the stents in two cases. All the patients recovered well. CONCLUSION: The neuroform stent-assisted coil placement may be a favorable technique for treatment of giant and large intracranial aneurysms. Further study is necessary to assess the long-term outcome.

Stent,balloon-assisted coiling and double microcatheter for treating wide-neck aneurysms in anterior cerebral circulation

Abstract

Objective:

To investigate the clinical application of adjuvant coiling techniques in treating anterior-circulation wide-necked aneurysms.

Methods:

Over 4·5 years, 93 anterior-circulation wide-neck aneurysms in 81 patients were treated with different endovascular techniques: balloon-assisted, stent-assisted, and double-microcatheter coiling. Demographic, clinical, and angiographic data were reviewed retrospectively.

Results:

Of the 93 aneurysms, 45 were treated using stent, 28 using balloon, and 20 using double microcatheter. The proportion of ruptured aneurysms was significantly lower in the stent group (53·3%) than in the balloon (71·4%) or the double-microcatheter group (75%). Stent embolization was used for 61·1% of aneurysms located in the internal carotid artery, whereas aneurysms in the anterior communicating and middle cerebral arteries were mainly treated with balloon remodeling (42·9%) and double microcatheter (52·4%). The majority of aneurysms with neck ≧ 7 mm (87·5%) and all aneurysms with a dome/neck ratio < 1·0 (100%) were treated by stent-assisted coiling. For aneurysms with neck < 4 mm, the mean dome/neck ratio was 0·93 in the stent group, 1·08 in the balloon group, and 1·16 in the double-microcatheter group. Total occlusion was achieved in 21 cases (46·7%), with the rates for stent being significantly lower than for balloon (78·6%) or double microcatheter (75·0%). Clinical outcome was favorable in 73 cases (Glasgow Outcome Scale (GOS) 4–5) and fair in 4 (GOS 3), while 2 were severely disabled (GOS 2) and 2 others died (GOS 1).

Conclusion:

Double microcatheter was better for distal aneurysms with dome/neck ratio of 1·1–1·2, while stent was better for proximal aneurysms with an extremely wide neck (≧ 7 mm) and for loudspeaker-shaped aneurysms (dome/neck ratio < 1·0) with poor vessel condition. For emergency cases, both balloon remodeling and double microcatheter are better choices than stent.

Experiences and complications in endovascular treatment of paraclinoid aneurysms

Endovascular treatment is a promising therapeutic alternative for paraclinoid aneurysms. The purpose of this study was to assess the feasibility and results of endovascular treatment for these lesions. We retrospectively reviewed the clinical data, results and complications of endovascular treatment of a series of 47 consecutive patients with paraclinoid aneurysms. Nineteen of these patients presented with acute subarachnoid hemorrhage, and 28 patients were treated for unruptured aneurysms. Endovascular treatment was performed for 50 aneurysms in 47 patients including stent-assisted coiling (19), balloon-assisted coiling (five), coiling without adjunctive techniques (25) and stent alone (one). Technical failures occurred in two patients (one stent deployment failure due to unsuccessful distal access across the aneurysm neck and one coiling failure due to unsuccessful microcatheter navigation through the stent). Periprocedural complications were observed in six patients (12.8%), with permanent morbidity in one patient resulting from a thromboembolic event. Immediate complete occlusion was achieved in 36 aneurysms (72%). During follow up, enlargement of a partially occluded giant aneurysm was observed in one patient, which was treated with parent artery occlusion. No delayed hemorrhagic complications were seen in the remaining patients. Endovascular treatment is technically feasible and safe in most patients with paraclinoid aneurysm, with a low rate of procedural complications.

目的 总结血管内支架技术辅助弹簧圈治疗颅内复杂动脉瘤的疗效，探讨其技术要点、并发症防治及评估该技术的安全性。方法 回顾性分析106例颅内复杂动脉瘤血管内支架技术应用。单纯支架技术6例，一期支架辅助弹簧圈治疗动脉瘤59例，二期支架结合弹簧圈栓塞动脉瘤40例，一期治疗病例中，先放微导管后放支架28例，先放支架后放微导管31例。结果 106例患者宽颈动脉瘤60例，梭形动脉瘤25例、夹层动脉瘤15例、假性动脉瘤6例。支架无法到位1例，105例第一次栓塞术后即时造影动脉瘤完全栓塞70例(66．7％)，动脉瘤大部分栓塞35例(33．3％)。术中动脉瘤破裂3例，术后脑梗塞4例，支架移位4例。80例3个月至24个月造影随访，动脉瘤消失50例(62．5％)，部分残留30例(37．5％)，其中20例行再次弹簧圈栓塞，完全栓塞15例(75％)。80例两次完全栓塞共65例(82．5％)。临床随访105例病人死亡1例，术后遗留永久性神经功能障碍2例。结论 支架技术辅助微弹簧圈栓塞提高了颅内复杂动脉瘤的近期疗效，是治疗颅内复杂动脉瘤的一种有效方法，但长期疗效尚有待进一步的随访研究。     

Stent-assisted coiling strategies for the treatment of wide-necked basilar artery bifurcation aneurysms

Stent-assisted coiling is now the preferred treatment option for wide-necked basilar artery bifurcation aneurysms (BABA). However, the optimal choice of specific treatment strategies is still not well documented. In this paper, based on the “two-neck” theory of BABA, we classified the stent-assisted coiling treatment of BABA into three types: unilateral stent-assisted coiling, unilateral stent plus contralateral microcatheter or microwire-assisted coiling, and bilateral stent-assisted coiling. We assessed the feasibility and effectiveness of different stent-assisted coiling strategies for the treatment of BABA. Twenty-three BABA patients treated with stent-assisted coiling between May 2003 and September 2012 were included. Of the 23 aneurysms, 16 were treated with unilateral stent-assisted coiling, two were treated with unilateral stent and microcatheter or microwire-assisted coiling, and five were treated with bilateral stent-assisted coiling. All 23 BABA were successfully embolized, with a technical success rate of 100%. According to the Raymond classification, the immediate procedural outcome was grade I in nine patients, grade II (neck residue) in four patients and grade III (body filling) in 10 patients. The rate of procedure-related complications was 4.3% (1/23), where intra-operative hemorrhage occurred during coiling due to rupture of the aneurysm. Of the 23 patients, 16 (69.6%) had angiographic follow-up. The mean follow-up duration was 13.5 months (range 1–46 months). Angiographic follow-up showed complete occlusion in 10 patients (62.5%), improvement in two patients (12.5%), stability in three patients (18.7%), and recanalization in one patient (6.25%). The various stent-assisted coiling strategies available at present are feasible and effective for the treatment of wide-necked BABA.
