Background:

Examine the clinical and technical outcomes following the placement of peripheral FDS and Identify any predictors of poor technical and clinical outcomes

Material(s) and Method(s):

We performed a retrospective analysis of a multicenter prospective cohort of all consecutive stroke patients with BAO who underwent MT. We compared clinical outcomes between BAO patients stratified by ENI. Multivariate analyses were performed to determine the impact of ENI on favorable 90-day outcome (modified Rankin scale of 0-3) and report factors contributing to ENI.

Result(s):

A total of 237 patients were included. An ENI was seen in 70 (30%) patients. Outcomes were significantly better in ENI+ patients, with 84% achieving favorable outcome (mRS 0-3) at 3 months versus 30% for ENI- patients (p<0.0001). In multivariate analysis, ENI was an independent predictive factor associated with higher rates of favorable outcome (Odds-ratio 18.12 [3.95-83.10], p=0.0001). A higher number of passes (Odds-ratio 0.62 [0.43-0.89], p=0.010) and need for stenting (Odds-ratio 0.27 [0.07-0.95], p=0.041) were negatively associated with ENI.

Conclusion:

ENI at day 1 following MT for BAO is a strong independent predictor of a favorable 3-months clinical outcome.
