Y-Stenting Endovascular Treatment for Ruptured Intracranial Aneurysms : A Single-Institution Experience in Korea

Objective

Stent-assisted coiling on intracranial aneurysm has been considered as an effective technique and has made the complex aneurysms amenable to coiling. To achieve reconstruction of intracranial vessels with preservation of parent artery the use of stents has the greatest potential for assisted coiling. We report the results of our experiences in ruptured wide-necked intracranial aneurysms using Y-stent coiling.

Methods

From October 2003 to October 2011, 12 patients (3 men, 9 women; mean age, 62.6) harboring 12 complex ruptured aneurysms (3 middle cerebral artery, 9 basilar tip) were treated by Y-stent coiling by using self-expandable intracranial stents. Procedural complications, clinical outcome, and initial and midterm angiographic results were evaluated. The definition of broad-necked aneurysm is neck diameter over than 4 mm or an aneurysm with a neck diameter smaller than 4 mm in which the dome/neck ratio was less than 2.

Results

In all patients, the aneurysm was successfully occluded with no apparent procedure-related complication. There was no evidence of thromboembolic complication, arterial dissection and spasm during procedure. Follow-up studies showed stable and complete occlusion of the aneurysm in all patients with no neurologic deficits.

Conclusion

The present study did show that the Y-stent coiling seemed to facilitate endovascular treatment of ruptured wide-necked intracranial aneurysms. More clinical data with longer follow-up are needed to establish the role of Y-stent coiling in ruptured aneurysms.     

Y-Stent embolization technique for intracranial bifurcation aneurysms

Wide-necked bifurcation aneurysms often require the use of the technically complex Y-stent technique, which has recently been shown to narrow bifurcation angle in a hemodynamically favorable manner. We sought to evaluate the single center efficacy and safety of Y-stent supported aneurysm coil embolization. All patients undergoing Y-stent supported coiling between September 2006 and December 2012 were identified; records were analyzed for procedural results and complications, with follow-up evaluated for occlusion rate and neurological adverse events. Twenty consecutive patients underwent technically successful Y-stent supported coiling, with complete aneurysm occlusion achieved in 19/20 cases (95%). There were no peri-procedural clinically evident neurological complications following Y-stenting. Clinical follow-up was available for a mean of 20.0 months and radiographic follow-up was available for a mean of 18.5 months. During the follow-up period, three patients (15%) required re-treatment with through-stent coiling for recanalization. At latest follow-up, Raymond grade I occlusion was achieved in 16 patients (80%), Raymond grade II occlusion achieved in four patients (20%) and Raymond grade III occlusion in zero patients. Y-stenting for complex intracranial aneurysms appears effective in achieving durable aneurysm occlusion with an acceptable safety profile. Though the procedure is technically more complex than single-stent procedures, the Y-stent configuration should be considered when single-stent supported coiling is not feasible or sufficient.

Y-stenting with braided stents for wide-neck intracranial bifurcation aneurysms. A single-center initial experience

IntroductionThe treatment of wide-neck bifurcation aneurysms is still challenging despite the use of new techniques, such as Y-stenting, the waffle-cone technique and intrasaccular flow disrupters, in recent years. Moreover, the use of flow diverter stents in bifurcation aneurysms has been proposed by several teams, although the results remain controversial. This study aims to evaluate the feasibility and efficacy of Y-stent assisted coiling of bifurcation aneurysms with braided stents.MethodsWe retrospectively reviewed all patients in whom Y-stenting with braided stents had been performed in our center. Six patients were identified and analyzed. Technical success, complications, angiographic outcomes, procedural data, and follow-up controls are reported here. This study was approved by our local ethical committee.ResultsTechnical success was achieved in all procedures. Overall procedure-related morbidity and mortality was 0%. In the immediate post-treatment angiography, adequate occlusion (neck remnant or total occlusion) was observed in all patients. Short- and long-term follow-up angiography showed adequate occlusion of the aneurysms.ConclusionsIn this small, retrospective single-center analysis we showed that Y-stent assisted coiling with braided stents is a safe and feasible technique. Moreover, it has a high immediate occlusion rate and very good long-term stability.
