Abstract
Objectives:: Endovascular treatment of intracranial aneurysms (IAs) has evolved in recent years and is currently the preferred treatment worldwide. We analyzed the trends in the number of patients, number of aneurysms, aneurysm characteristics, and techniques used in a pure endovascular cohort of patients treated in a reference center. Materials and Methods:: Between 2010 and 2020, a retrospective data collection of patients who underwent endovascular intervention of IAs was performed. We used the Mann-Kendal test to evaluate the trends. In addition, the moving-average technique was used to assess smoother curves. Results:: Eight hundred and forty-five aneurysms were treated in 765 patients, the mean age was 53.9 14.6 years and 81% were women. The number of patients (P = 0.016) and aneurysms (P = 0.003) increased significantly. Unruptured (P = 0.029) and posterior communicating artery aneurysms increased their frequency of treatment (P = 0.042). Balloon remodeling (P = 0.01) and the use of flow diverters showed a positive trend (P = 0.016). Conclusion:: There have been an increased number of patients and aneurysms treated endovascularly at our institution, including unruptured and posterior communicating aneurysms. Advanced endovascular techniques also increased. Comparative studies including surgical cases must be done in our region to determine the best approach.
