Stent placement for the treatment of complex internal carotid bifurcation aneurysms: a review of 16 cases

Abstract

AIm: Stent placements for the treatment of complex internal carotid bifurcation aneurysms are not well documented yet. In this article, we reported a series of 16 such cases to evaluate the feasibility, safety and effectiveness of stent placement for these particular lesions. results: Sixteen stents, including 10 Enterprise, 4 Neuroform, 1 Solitaire and 1 one balloon-mounted coronary stent (BX), were successfully deployed in this series. Immediate angiogram showed complete occlusion in 5, neck remnant in 2 and residual sac in 9. No procedure-related complication occurred. Angiographic follow-up results (mean, 12.1months) were available in 15 patients, 9 of the aneurysms were cured, 1 was improved, 3 were stable, 2 were recanalized, and 1 was retreated. Clinical follow-up (mean, 28.6months) of all 16 patients demonstrated no neurologic deterioration or rebleeding.COnClusIOn: Our result suggests that stent placement for the treatment of complex ICA bifurcation aneurysms is feasible and safe. However, its efficacy should be further evaluated by larger case series and more adequate follow-up. BulGulAr: 10 Enterprise, 4 Neuroform, 1 Solitaire ve 1 balona monte edilmiş koroner stent (BX) dahil olmak üzere 16 stent bu seride başarıyla yerine yerleştirildi. Hemen yapılan anjiyogram 5'inde tam oklüzyon, 2'sinde kalan boyun kısmı ve 9'unda rezidüel kese gösterdi. İşlemle ilgili komplikasyon oluşmadı. Anjiyografik takip sonuçları (ortalama 12,1 ay) 15 hastada mevcuttu ve anevrizmaların 9'u tamamen iyileşmişti, 1'i daha iyiydi, 3'ü stabildi, 2'sinde tekrar kanalizasyon vardı ve 1'i tekrar tedavi edildi. Klinik takip (ortalama 28,6 ay) 16 hastanın hiçbirinde nörolojik bozulma veya tekrar kanama göstermedi. sOnuÇ: Sonucumuz kompleks IKA bifurkasyon anevrizmaları için stent yerleştirmenin kullanılabilir ve güvenli olduğunu düşündürmektedir. Ancak etkinliği daha büyük vaka serilerinde ve yeterli takiple daha ileri olarak değerlendirilmelidir.
