Solitaire AB stent-assisted coiling of wide-necked intracranial aneurysms: short-term results from a prospective, consecutive, European multicentric study

Introduction

Solitaire AB stent-assisted coiling facilitates the endovascular treatment of wide-necked intracranial aneurysms. Solitaire Aneurysm Remodeling is the first prospective, consecutive, European multicentric study whose main objective was to evaluate the safety, short-, and long-term efficacy of the Solitaire AB stent. This first analysis is focused on the short-term results.

Methods

After exclusion of one patient, 66 Solitaire AB stents were used to treat via endovascular approach 64 aneurysms (63 patients) in seven European centers. Technical and clinical complications were recorded. A core laboratory evaluated the angiographic efficacy by using the Raymond classification scale.

Results

The mean width of aneurysm sac was 7.5 mm, and the mean diameter of aneurysm neck was 4.7 mm. Complete occlusion was achieved in 27 aneurysms (42.2 %); neck remnant was seen in 25 aneurysms (39.1 %) and aneurysm remnant in 12 aneurysms (18.7 %). Technical and clinical complications related to the procedure were encountered in eight patients (12.7 %). Postprocedural modification of the clinical status was observed in one patient (1.6 %). No patients died (0 %); one had a permanent deficit (1.6 %), and one had a transient deficit (1.6 %). Treatment-related mortality was 0 %, and permanent morbidity was 1.6 %.

Conclusion

The Solitaire AB stent has an excellent rate of technical success navigation with the absence of dislodgement. The safety and short-term efficacy are comparable to those previously reported with coiling alone. Mid- and long-term follow-up will be required to elucidate the impact of the Solitaire AB stent on recanalization rate.     

Coil embolization of anterior circulation aneurysms supported by the Solitaire™ AB Neurovascular Remodeling Device

Introduction

The purpose of the study is to evaluate patients with wide-necked or complex aneurysms of the anterior circulation who underwent Solitaire? AB Neurovascular Remodeling Device-assisted coil embolization.

Methods

From February 2008 to March 2009, consecutive data were collected from 45 patients with anterior circulation aneurysms. Eighteen of the patients presented with acute subarachnoid hemorrhage. Forty-six aneurysms were treated with the aid of different applications (n?=?49) of the Solitaire? AB Remodeling Device followed by standard coiling procedure (n?=?43) using bioactive coils or/and bare coils.

Results

Successful positioning of the remodeling device was obtained in 95.9% of the cases. There were two thromboembolic complications (4.1%) and one severe vasospasm requiring retrieval of the device. Permanent procedural morbidity was observed in one patient (2%). The proportion of patients in whom Raymond class 1 occlusion was obtained was 53.5% (n?=?23). Raymond class 2 occlusion was achieved in 42% (n?=?18) and Raymond class 3 occlusion in 4.7% (n?=?2). Thirty-nine patients left the hospital with a good clinical status.

Conclusion

The initial technical and clinical results of Solitaire? AB device-assisted coiling of aneurysms in the anterior circulation are highly encouraging. This technique may enhance the possibilities of the endovascular treatment of these aneurysms in clinical routine.

Mechanical Recanalization Using Solitaire AB Device for Severe Thromboembolic Events in Endovascular Treatment of Intracranial Aneurysms

Introduction

Severe thromboembolism with complete occlusion of the proximal arteries during or after coil embolization can cause serious neurologic deficits. The study aimed to assess the effectiveness and safety of Solitaire AB device as a rescue therapy for severe thromboembolic complications in the endovascular treatment of intracranial aneurysms.

Materials and Methods

Between February 2013 and April 2016, 1047 intracranial aneurysms treated with endovascular procedures were retrospectively reviewed in our center. Severe thromboembolisms occurred in ten patients and were treated by Solitaire AB device including clot retriever and permanent stent deployment.

Results

The location of arterial occlusion was distal to the aneurysm rather than the coil/parent artery interface or in-stent area. Four patients had distal thromboembolic events before coil embolization, and six patients had it after coiling. The complete arterial recanalization (TICI 3) was achieved in all patients, and no cerebral hemorrhage was related to the procedure after the rescue therapy. Among these patients with the aforementioned neurovascular procedures, the mean Glasgow Outcome Scale (GOS) score was 4.5 (ranging 3–5) and eight cases had good outcome with a score of GOS 4–5 at discharge, while eight patients presented mRS ≤2 at 3-month follow-up.

Conclusions

These results demonstrate that mechanical recanalization using Solitaire AB device seems to be effective and safe as a rescue therapy for severe thromboembolic events during cerebral aneurysm embolization.

     

Stent-assisted coil embolization of intracranial aneurysms using the Solitaire™ AB Neurovascular Remodeling Device: initial and midterm follow-up results

Introduction

The purpose of this retrospective review was to present our experience in using the Solitaire? AB Neurovascular Remodeling Device in the stent-assisted treatment of intracranial aneurysms, focusing on midterm results. To date, this is the largest series using the Solitaire? AB Neurovascular Remodeling Device.

Methods

From February 2008 to December 2010, 102 patients harboring 104 wide-necked or complex intracranial aneurysms were consecutively enrolled. Forty-five patients presented with an acute subarachnoid hemorrhage. Stent implantation was combined with a standard coiling procedure in 100 patients; in 13 of them, by bailout stenting. On average, at least one clinical and angiographic follow-up was available in 63 patients after 6.3 months. Forty-nine patients were followed for up to 13.6 months.

Results

Of the stents, 98.4 % could be deployed successfully. A Raymond class 1 occlusion was obtained in 51 % of the aneurysms, a Raymond class 2 occlusion in 44 %, and in the remaining 5 % a Raymond class 3 occlusion was obtained. Procedure-related morbidity was 3.9 % (n?=?4) and procedure-related mortality was 2.9 % (n?=?3). During the follow-up period, 39.2 % of the aneurysms showed further thrombosis, 45.1 % remained unchanged, and 15.7 % recanalized. In the follow-up clinical examination according to the modified Rankin Scale, 16.3 % of all patients presented with clinical improvement, 73.5 % were unchanged, and 10.2 % of patients deteriorated.

Conclusion

Considering that stent-assisted coiling is indicated in unfavorable aneurysms, which are not amenable to standard coiling procedures, the Solitaire AB stent proved to be an efficient and safe device in midterm angiographic and clinical follow-up results.
