Abstract

Abstract:

Objective:

To evaluate the medium and long term outcome of revascularization and stenting of nonacute basilar artery occlusion.

Methods:

12 cases of nonacute basilar artery occlusion for over 24 hours treated by endovascular revascularization in our center were retrospectively collected and analyzed. Complications and recurrent ischemic events during the follow-up period were recorded. The modified Rankin scale (mRS) scores were used to compare the relative changes of pre- and post-procedure.

Results:

Among the 12 patients, 11 (91.7%) obtained successful recanalization. However, 2 patients developed procedural complications that worsened their situation. 8 patients received imaging follow-up during the median 12 months, restenosis occurred in 2 cases, and both are symptomatic.In the subsequent clinical follow-up after the procedure, 2 ipsilateral strokes and 1 ipsilateral transient ischemic attack occurred. The mRS scores decreased significantly in the first 3 months after the procedure in survivors.

Conclusions:

Revascularization and stenting of nonacute basilar artery occlusion can prevent recurrent ipsilateral ischemic event and improve recovery, but re-occurring stenosis should draw more attention.

Key words: Basilar occlusion, Nonacute, Intervention treatment, Modified Rankin scale
