Abstract

AIM: We report our experience with flow diverter devices in the treatment of intracranial aneurysms arising from anterior circulation with mid and long-term follow-up.

MATERIAL AND METHODS: 78 aneurysms in 61 patients (range 25-81 years, 13 male, 48 female) were treated with flow diverter devices. 40 (51,3%) aneurysms were treated with pipeline embolization device (PED), 24 (30,8%) aneurysms were treated with SILK stent, 12(15,4%) aneurysms were treated with flow redirection endoluminal device (FRED) and two aneurysms were treated with P64 Flow Modulation Device (P64). Angiographic follow-up data at six month and one yea were recorded and the occlusion degrees of aneurysms were evaluated according to the scale which was formed by Kamran et al.

RESULTS: At six month follow-up, complete occlusion (grade 4) rate was 60,8% and at one year increased to 74,3%. Statistical analysis revealed significant difference (p=0,002) between six month and one year follow-up results but there was no significant association (p=0,531, p=1,000) between aneurysm occlusion rate and aneurysm diameter. Two patient (3,2%) died due to hemorrhagic complication.

CONCLUSION: Endovascular treatment of intracranial anterior circulation aneurysms with flow diverters is a safe and effective treatment option. A high rate of stable occlusion is achieved at long term follow-up.
