Safety and efficacy of rescue endovascular treatment in ischemic stroke patients with early neurological deterioration caused by large vessel occlusion.

OBJECTIVES

The optimal treatment after deterioration following ischemic stroke has not been established in the current guidelines. Therefore, this study evaluated the efficacy of rescue endovascular treatment in patients with early neurological deterioration after acute ischemic stroke.

METHODS

This study analyzed data retrospectively retrieved from the electronic medical records at the First Affiliated Hospital of Anhui Medical University.

RESULTS

A total of 20 patients were included in the rescue endovascular treatment group and 23 in the medical group. The 90-day favorable outcome rate in the rescue endovascular treatment group was significantly better than that of the medical group (75.0% 34.8%, =0.031). However, no significant difference in all-cause mortality within 90 days was observed between the rescue endovascular treatment group and the medical group (5.0% 8.7%, =1.000). The 90-day prognosis of patients with mild stroke of anterior circulation and large vessel occlusion who underwent rescue endovascular treatment after deterioration was significantly better than that of those in the medical group (76.5% 31.6%, =0.010).

CONCLUSION

Rescue endovascular treatment is effective and safe for patients with ischemic stroke and deterioration due to large vessel occlusion, leading to no significant increase in the risk of hemorrhage or death even when the time window exceeds 24 h.
