To report our experience with the 2.5-mm Surpass EvolveTM flow diverter (FD) in the treatment of distal small cerebral artery aneurysms. This study included 41 patients with 52 aneurysms. Clinical and radiological records and procedural and follow-up outcomes were reviewed retrospectively. The aneurysm morphology was saccular in 45 patients, dissecting in five patients, and fusiform in two patients. Fifty-two aneurysms were treated with 41 Surpass Evolve FDs. The mean diameters of the proximal and distal parent arteries were 2.56 and 2.17 mm, respectively. The mean duration of follow-up was 16.2 ± 6.6 (6-28) months. Four (10%) patients had acute subarachnoid hemorrhage. In the same session, two patients with two tandem aneurysms and one patient with four tandem aneurysms were treated using a single FD. Intraprocedural hemorrhage and femoral artery pseudoaneurysm occurred in two patients during the procedure. Digital subtraction angiography was performed on 38/41 (92%) patients with 47/52 (88%) having aneurysms. Complete occlusion (OKM D) was observed in 39/47 (82%) aneurysms, and near complete-complete occlusion (OKM C-D) was observed in 46/47 (98%) aneurysms. Endovascular treatment of distal cerebral artery aneurysms with the 2.5-mm Surpass Evolve < sup > TM < /sup > FD provides a high rate of aneurysm occlusion with low periprocedural complications, even in ruptured and tandem aneurysms.
