Introduction: Intracranial aneurysms (IA) are a focal dilatation of the vessel wall, the rupture of these, causes subarachnoid hemorrhage. Until now, endovascular management is the ideal treatment, providing the interventionist a range of options among which the stent and coils embolization stands out because of its occlusion rate. This study presents the results of a retrospective cohort comparing the effectiveness, morbidity, and mortality of IA treatment with laser-cut stent-assisted coils versus braided stents. Methodology: Retrospective cohort of patients diagnosed with unruptured intracranial aneurysms treated with coil-assisted laser-cut stents or braided stents between January 2014 and December 2021. Results: In total, 138 patients with 147 intracranial aneurysms were analyzed, 91 of them were treated with laser-cut stent and 56 with braided stents. The main antecedent was arterial hypertension (48.55%). In the immediate angiographic control, a Raymond Roy scale (RRO) I was obtained in 86.81% of the patients with laser-cut stents and 87.50% of the patients with braided stents. In the angiographic follow-up at 12 months, an RRO I occlusion rate of 85.19% was reported in both groups. Perioperative complications occur in 16 patients treated with laser-cut stents and 12 patients treated with braided stents. Three patients presented bleeding complications during the 12-month follow-up, of which two correspond to patients treated with braided stents and one with a laser-cut stent. Conclusion: Treatment of patients with intracranial aneurysms with laser-cut stents or braided stents and coils is just as safe and effective.
