Background: Neuroform stent-assisted coil embolization facilitates the endovascular treatment of wide-necked intracranial aneurysms. However, the safety and efficacy of its long-term use have not been fully elucidated.
Objective: To retrospectively examine the long-term results of Neuroform stent usage in conjunction with coil embolization in wide-necked intracranial aneurysms.
Methods: Between November 2002 and December 2010, 79 patients harboring wide-necked intracranial aneurysms were treated with use of the Neuroform stent. The stenting procedure failed in 2 patients. Therefore, 77 patients harboring 79 intracranial aneurysms were included for analysis. Patient and aneurysm characteristics, progression of aneurysm occlusion, and occurrence of complications were analyzed. Follow-up imaging included digital subtraction angiography (DSA) or magnetic resonance angiography (MRA). Kaplan-Meier analysis, as well as univariate analysis were performed to determine the progression of aneurysm occlusion and to examine the predictive factors for complete aneurysm occlusion, respectively.
Results: Overall, complete aneurysm occlusion was observed in 42.4% of the cases immediately after treatment and progressed to 96.5% at 7-year follow-up. The mean angiographic follow-up time was 25.8 months (range, 0-84 months). Eleven aneurysms (14%) were re-treated. Sixty-eight patients (88.3%) had favorable clinical outcome with a modified Rankin Scale (mRS) ≤ 1, 3 patients (3.9%) had an mRS of 2, and 5 patients (6.5%) did not have a clinical follow-up. The mean clinical follow-up time was 45.4 months (range, 3-92 months). One patient (1.3%) died of a procedure-related hemorrhage.
Conclusion: Neuroform stent-assisted coil embolization of wide-necked intracranial aneurysms prevents hemorrhage and provides a high rate of aneurysm occlusion at long-term follow-up.

Background: Surgical clipping and endovascular coiling are well-established treatments for acutely ruptured intracranial aneurysms leading to acute subarachnoid hemorrhage (aSAH). However, these modalities have limitations, particularly in cases involving wide-necked, bifurcating, or dissecting aneurysms. Flow diverter (FD) devices, initially used for unruptured aneurysms, have emerged as an alternative treatment for ruptured aneurysms despite concerns about hemorrhagic complications.

Objective: To investigate the effectiveness, safety, and efficacy of Atlas stents in the treatment of distal intracranial aneurysms (IAs).
Methods: We retrospectively analyzed patients with IAs who underwent stent-assisted coiling (SAC) from January 2018 to January 2022 and divided them into two groups: distal IAs treated with Atlas SAC and wide-necked aneurysms in other locations treated with SAC. The clinical data, imaging data, and postoperative follow-up data for the two groups of patients during hospitalization were collected.

Background: The Woven EndoBridge (WEB) is a treatment modality available for the treatment of intracranial aneurysms, specifically beneficial in wide-necked bifurcation aneurysms. Conventional sizing methods rely on the manipulation of aneurysm width and height measurements. This results in frequent need for re-sizing after initial WEB insertion attempts.
