    Endovascular treatment of wide-necked bifurcation aneurysms may be challenging. The waffle-cone technique can be used in these aneurysms in case of acute angulation between parent artery and distal artery of the aneurysm. Solitaire (R) stent (Ev3, Irvine, CA, USA) has the significant advantage of mitigating the potential complication risks. This study reports the second case in the literature in which endovascular treatment of a wide-necked bifurcation aneurysm with the double waffle-cone technique by using twin Solitaire (R) stents proved to be successful.

    The gently pull-back technique for neck bypass in treatment of wide-necked internal carotid artery aneurysms: A report of three cases and review of the literature
    (Sage Publications Inc, 2015-12-01) Kaçar, Emre; Hakyemez, Bahattin; NAS, ÖMER FATİH; Nas, Ömer F.; KAYA, AHMET TUFAN; Kaya, Ahmet; Erdoğan, Cüneyt; Kocaeli, Hasan; KOCAELİ, HASAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; 0000-0002-8813-6513; AAG-8561-2021; AAS-5392-2021
    Neck bypass failure in endovascular treatment of wide-necked internal carotid artery (ICA) aneurysms may adversely affect the technical success of the procedure. We used the gently pull-back technique to bypass the aneurysm neck and access the distal parent artery during endovascular treatment in patients with wide-necked ICA aneurysms. In this technique, a loop was made in the aneurysm and the distal parent artery was reached by using a small diameter microguidewire and a microcatheter. After providing reliable distal access, the microguidewire was removed and the whole system which consists of the microcatheter was gently pulled back. Finally the microcatheter was straightened and the aneurysm neck was passed. After crossing the aneurysm neck, a flow-diverting stent treatment and stent-assisted coiling were performed in three cases with wide-necked ICA aneurysm. The gently pull-back technique is a simple and effective method which requires no extra intravascular device and helps to bypass the aneurysm neck through a small diameter microguidewire and a microcatheter. This technique may be useful for neck aneurysm bypass in endovascular treatment of wide-necked ICA aneurysms.

    Modified Y-configured stents with the waffle-cone technique by use of solitaire® stent for patients with wide-necked bifurcation aneurysms
    (Springer, 2015-08-01) Nas, Ömer Fatih; Kaçar, Emre; Kaya, Ahmet; Erdoğan, Cüneyt; Hakyemez, Bahattin; NAS, ÖMER FATİH; KAYA, AHMET TUFAN; Erdoğan, Cüneyt; HAKYEMEZ, BAHATTİN; 0000-0002-3425-0740; Uludağ Üniversitesi Tıp Fakültesi Radyoloji Anabilim Dalı; 0000-0002-8813-6513; AAS-5392-2021; AAI-2318-2021; AAG-8561-2021; COE-1124-2022
    Endovascular treatment of wide-necked bifurcation aneurysms can be challenging, despite improvements in endovascular techniques. Y stent-assisted coiling is one such technique, but this may not be technically feasible, especially in cases of acute angulation between the proximal and distal parent arteries, and may require use of "modified Y-configured stents with the waffle-cone technique". We report three cases of wide-necked bifurcation aneurysms that were successfully treated by use of the Solitaire (R) stent.
