Aim:We report our experience of distal small artery aneurysms treated with the 2.5-mm Surpass Evolve flow diverter (FD).Material and Methods:Forty-one patients with 52 aneurysms were included in the study. Clinical and radiological records, procedural and follow-up outcomes were retrospectively evaluated.Results:The aneurysm morphology was saccular in fourty-five, dissecting in five, and fusiform in two. Totally fifty-two aneurysms were treated with 41 Surpass Evolve.The mean proximal and distal parent artery diameters were 2.56 mm and 2.17 mm respectively. The mean follow-up was 16.2±6.6 months. Four (10%) patients had acute subarachnoid hemorrhage. Two patients with two and one patient with four tandem aneurysms were treated with a single FD in the same session. Procedural complications occurred in two patients, intraprocedural hemorrhage and femoral artery pseudoaneurysm. Digital subtraction angiography was performed on 38/41 (92%) patients with 47/52 (88%) aneurysms. Complete occlusion (OKM D) was observed in 39/47 (82%), near complete-complete occlusion (OKM C-D) was observed in 46/47 (98%) aneurysms.Conclusion:The endovascular treatment of distal cerebral aneurysms with the 2.5 mm Surpass Evolve provides a high rate of aneurysm occlusion with low periprocedural complications even in ruptured and tandem aneurysms.
