Introduction “Neuroform Atlas stent’ is an open-cell stent that can be used in smaller caliber microcatheter for coil and is widely used in unruptured cerebral aneurysms. Because the Neuroform atlas stent has a thin wire and lower radial force, it is thought that a safer procedure will be possible even in ruptured case.

Aim of Study The safety and effectiveness of using the Neuroform Atlas stent for ruptured cerebral aneurysms were compared with simple coiling.

Methods Clinical and Radiological records of cases of coil embolization for ruptured aneurysms during 5 years were retrospectively reviewed. Patient data including procedural complication, follow-up result etc. were collected. The total population was divided into the simple coiling group and the Neuroform atlas group. The initial procedural complications and the angiographic follow-up result were compared.

Results The Neuroform atlas stents were used in 64 patients, and simple coiling was performed in 127 patients. Comparing the two groups, the rate of thromboembolism among early complications occurred in 6.3% (4 cases) in the atlas group compared to 3.9% (5 cases) in the simple coiling group. Of the total 117 patients who underwent angiographic follow-up, 45 patients were in the Atlas group, and among them, the rate of recurrence requiring treatment was 22.2% (10 patients), and the simple coiling group was 26.4% (19 patients).

Conclusion Considering the complicated anatomic conditions of the aneurysm-parent vessel in the stent group, the use of the Neuroform Atlas stent in ruptured cerebral aneurysms might be resonable.
