Objective

The aim of the present retrospective study is to compare outcome of the endovascular treatment using the Enterprise stent in intracranial wide-necked saccular and dissecting aneurysms.

Methods

Forty-six patients with 50 complex intracranial aneurysms admitted between June 2009 and November 2010 were treated using Enterprise stents. Thirty-one aneurysms were wide-necked saccular, 19 aneurysms dissecting. In 48 cases, aneurysms were occluded by stent-assisted coiling; in 2 cases, by stent alone.

Results

Among the aneurysms treated with the Enterprise stent, patient sex, aneurysm location, hypertension history and the immediate angiographic results differed significantly between the saccular and dissecting aneurysm groups. However, recurrence rate, clinical follow-up outcomes did not differ significantly between the saccular and dissecting groups. There was 1 (2%) procedure-related complication, which caused death in the saccular group. At mean 9.1-month follow-up, the result was good in all dissecting cases and good in 30 saccular cases. There was 1 recurrence in each group.

Conclusions

Enterprise stent is very useful for endovascular embolization of intracranial wide-necked saccular and dissecting aneurysms because it is easy to navigate and place precisely. The overall morbidity and mortality rates were low.  相似文献

Introduction We report the results of a prospective clinical study using a new self-expanding nitinol stent (Enterprise) designed for the treatment of wide-necked intracranial aneurysms. Methods We treated 31 saccular, wide-necked intracranial aneurysms in 30 patients. Ten aneurysms had recanalized after prior endovascular treatment without a stent, and 21 aneurysms had not been treated before. Results Stent deployment was successful in all procedures. Additional coil embolization was performed in all aneurysms. Initial complete angiographic occlusion was achieved in 6 aneurysms, a neck remnant was left in 18 aneurysms and there were 7 residual aneurysms. Angiographic follow-up examinations of 30 lesions after 6 months demonstrated 15 complete occlusions, 8 neck remnants and 7 residual aneurysms. One patient refused the 6-month angiographic follow-up. Spontaneous occlusion of the aneurysm had occurred in 14 patients, and 6 aneurysms showed recanalization. Four of these residual aneurysms were retreated. At the 6-month follow-up, 29 parent arteries were unaffected, whereas two parent vessels demonstrated minor asymptomatic narrowing at the stent site. Two patients experienced one or more possible or probable device-related serious adverse events during the 6-month follow-up period. There was no procedural morbidity or mortality at 6 months after the procedure. Conclusion The reported results demonstrated the safety and feasibility of the Cordis Neurovascular Enterprise stent in the treatment of wide-necked intracranial aneurysms. Initial clinical and angiographic results are favorable. Werner Weber and Martin Bendszus contributed equally to this work.  相似文献

Introduction

The novel Low-profile Visualized Intraluminal Support (LVIS?, LVIS and LVIS Jr.) device was recently introduced for stent-supported coil embolization of intracranial aneurysms. Periprocedural and midterm follow-up results for its use in stent-supported coil embolization of unruptured aneurysms are presented herein.

Methods

In this prospective multicenter study, clinical and radiologic outcomes were analyzed for 55 patients with saccular aneurysms undergoing LVIS-assisted coil embolization between October 2012 and February 2013. Magnetic resonance angiography or digital subtraction angiography was performed to evaluate midterm follow-up results.

Results

The standard LVIS device, deployed in 27 patients, was more often used in internal carotid artery (ICA) aneurysms (n?=?19), whereas the LVIS Jr. (a lower profile stent, n?=?28) was generally reserved for anterior communicating artery (n?=?14) and middle cerebral artery (n?=?8) aneurysms. With LVIS-assisted coil embolization, successful occlusion was achieved in 45 aneurysms (81.8 %). Although no instances of navigation failure or stent malposition occurred, segmentally incomplete stent expansion was seen in five patients where the higher profile LVIS was applied to ICA including carotid siphon. Procedural morbidity was low (2/55, 3.6 %), limited to symptomatic thromboembolism. In the imaging of lesions (54/55, 98.2 %) at 6-month follow-up, only a single instances of major recanalization (1.9 %) occurred. Follow-up angiography of 30 aneurysms (54.5 %) demonstrated in-stent stenosis in 26 (86.7 %), with no instances of stent migration. Only one patient suffered late delayed infarction (modified Rankin Scale 1).

Conclusion

The LVIS device performed acceptably in stent-assisted coil embolization of non-ruptured aneurysms due to easy navigation and precise placement, although segmentally incomplete stent expansion and delayed in-stent stenosis were issues.  相似文献

Introduction Aneurysms of the posterior cerebral artery (PCA) are rare, and most of the studies reported in the literature in which the endovascular approach was applied were carried out on a limited number of patients with PCA aneurysms. We retrospectively reviewed our cases of PCA aneurysms – at various locations and of differing shapes – that received endovascular treatment and evaluated the treatment outcome. Methods From January 1996 to December 2006, 13 patients (eight females and five males) with 17 PCA aneurysms (nine fusiform and eight saccular) were treated using the endovascular approach. The age of the patients ranged from 20 to 67 years, with a mean age of 44 years. Of the 13 patients, ten presented with intracranial hemorrhage, and one patient, with a large P2 aneurysm, presented with trigeminal neuralgia; the aneurysms were asymptomatic in the remaining two patients. Results All 13 patients were successfully treated, with only one procedure-related symptomatic complication. Seven patients were treated by occlusion of the aneurysm and parent artery together; five patients, by selective embolization of the aneurysm; one patient, by partial coiling. Although infarctions were found in two patients treated with selective embolization and in three patients treated with parent artery occlusion, only one patient with a ruptured P2 aneurysm treated with parent artery occlusion developed transient amnesia as an ischemic symptom. Conclusion Posterior cerebral artery aneurysms can be treated safely with either occlusion of the aneurysm together with the PCA or with a selective coil embolization. Infarctions may occur after endovascular treatment, but they are rarely the cause of a disabling symptom.  相似文献

Broad-based intracranial aneurysms: thrombosis induced by stent placement   总被引:26,自引:0,他引:26  
For broad-based intracranial aneurysms, both surgical and endovascular treatments are demanding. Flexible metallic stents provide an alternative treatment option for these patients, because they enable coil placement through the stent mesh. Evidence from extracranial arteries indicates that aneurysms may also spontaneously thrombose after stent placement. This case report documents three patients with saccular intracranial aneurysms in whom aneurysm thrombosis occurred after stent placement only, without additional packing of the aneurysms with coils.  相似文献

Introduction The aim of this retrospective study was to evaluate the clinical efficacy and limitations of different endovascular modalities in the treatment of very large and giant intracranial aneurysms. Methods A group of 20 patients with very large and giant intracranial aneurysms treated by endovascular approaches were retrospectively analyzed. Of the 20 patients, 9 had been treated by parent artery occlusion, 8 by coil embolization, and 3 with an intracranial covered stent. Two recurrent aneurysms initially treated with coil embolization were retreated with an intracranial covered stent. Patients were followed for 9–83 months after the procedure. Results Endovascular treatment was technically feasible in all 20 patients. One patient died 7 days after the procedure from rebleeding caused by incomplete aneurysmal occlusion. Immediate postprocedural angiograms showed that complete occlusion was achieved in 11 aneurysms, subtotal occlusion in 7, and incomplete occlusion in 2. The final angiographic results in the other 19 surviving patients confirmed complete occlusion of 15 aneurysms, subtotal occlusion in 3, and incomplete occlusion in 1. Clinical evaluations performed at the final follow-up visit showed an excellent outcome in 11 patients and a good outcome in 8. Conclusion Endovascular treatment of giant intracranial aneurysms with coil embolization is often associated with a low complete occlusion rate and a high recanalization rate, and parent artery occlusion remains a practical option in selected patients. Based on our limited experience, the use of an intracranial covered stent appears to be a relatively simple and safe procedure for occluding very large and giant aneurysms while still maintaining the patency of the parent artery.  相似文献
