Safety and effectiveness of Neuroform Atlas stent-assisted coil embolization for ruptured intracranial aneurysms.

OBJECTIVE

The treatment outcomes of ruptured intracranial aneurysms using the Neuroform Atlas stent were evaluated.

METHODS

This study represents a retrospective review that included patients who underwent endovascular treatment for ruptured aneurysms at a single institution. Between January 2018 and September 2022, endovascular treatments including simple coiling or Neuroform Atlas stent-assisted coil embolization were performed in 191 patients with ruptured intracranial aneurysms.

RESULTS

Intraprocedural rupture was observed in 11 (8.7%) patients in the Simple Coiling (SC) group, which was slightly higher than that in 4 (6.3%) patients in the Neuroform Atlas stent-assisted coiling (NASAC) group (p=0.241). However, Thromboembolic event (TEE) was slightly more prevalent in the NASAC group, with 4 (6.3%) cases as compared to the 5 (3.9%) cases in the SC group (p=0.235). The retreatment rate was slightly higher in the SC group, with 19 (26.4%) patients as compared to the 10 patients (22.2%) in the NASAC group (p=0.342).

CONCLUSIONS

The use of the Neuroform Atlas stent (NAS) for ruptured aneurysms might be safe and effective.
