摘要

Objective

This study aimed to investigate the efficacy of endovascular embolization in treating ruptured intracranial aneurysms (RIAs).

Methods

RIA patients (n = 89) were grouped according to different surgical methods. The control group (n = 42) received aneurysm clipping surgery, whereas the observation group (n = 47) received endovascular embolization. The National Institutes of Health Stroke Scale (NIHSS) was used to assess neurological function pre-treatment and at 7 days post-treatment. Oxidative stress status, including superoxide dismutase (SOD) levels and serum malondialdehyde (MDA) levels, was compared between the two groups pre-treatment and at 7 days post-treatment. Intraoperative bleeding, operative time, and hospitalization time were compared between the two groups. Vascular endothelial function, including von Willebrand factor (vWF), endothelin-1 (ET-1), and nitric oxide (NO), was evaluated pre-treatment and 3 months post-treatment. Postoperative complications and surgical outcomes were observed.

Results

After treatment, compared to the control group, the observation group had lower NIHSS scores, higher SOD levels, and lower MDA levels, with statistically significant differences (all P < 0.001); the observation group also had less intraoperative bleeding, shorter operation times, and shorter hospital stays, along with lower vWF and ET-1 levels, higher NO levels, and statistically significant differences (all P < 0.001). The incidence of postoperative complications was lower in the observation group, with a statistically significant difference (P = 0.048). The therapeutic effect was better in the observation group, with a statistically significant difference (P = 0.041).

Conclusion

Compared with microscopic aneurysm clipping, endovascular embolization offers better efficacy for patients with RIA and causes less vascular endothelial damage.
