Abstract
Background
Endovascular treatment for patients with symptomatic nonacute middle cerebral artery occlusion remains clinically challenging, and proof of a beneficial effect on functional outcome is lacking. We aim to evaluate the effectiveness and safety of endovascular recanalization for patients with symptomatic nonacute middle cerebral artery occlusion.
Methods
Ninety‐eight patients with symptomatic atherosclerotic nonacute middle cerebral artery occlusion were divided into drug treatment groups (42) and endovascular treatment groups (56). The rate of recanalization, peri‐procedural complications, and follow‐up results were evaluated.
Results
Among the 56 patients who received endovascular treatment, 53 (94.6%) achieved successful recanalization. The rate of peri‐procedural complications was 7.1% (4/56), and the death rate was 1.8% (1/56). Any stroke within 90 days was 7.1% (4/56). Among the 42 patients in drug treatment group, any stroke within 90 days was 19.0% (8/42), death rate was 0.
Conclusion
Among patients with symptomatic nonacute middle cerebral artery occlusion with a short length of occlusion and a moderate‐to‐good collateral circulation, endovascular treatment seems to be safe. And endovascular treatment could reduce the recurrence rate of stroke.
