Résumé

The study aimed to compare outcomes of mechanical thrombectomy (MT) in pediatric patients with acute ischemic stroke (AIS) caused by focal cerebral arteriopathy (FCA) versus cardioembolism (CE). Data from the Save ChildS and KidClot cohorts were merged. Children with AIS because of FCA or CE that underwent MT were included. The study used the Childhood Arterial Ischemic Stroke Standardized Classification and Diagnostic Evaluation (CASCADE) for stroke cause assessment. Descriptive statistics and multivariable regression models were used to analyze final modified thrombolysis in cerebral infarction (mTICI) scores, periprocedural complications, and functional outcomes assessed by the modified Rankin scale (mRS) at 6 to 12 months. The analysis included 60 children with 14 FCA and 46 CE cases. CE etiology was associated with better revascularization (good to excellent thrombolysis in cerebral infarction scores) and shift toward better outcomes (common adjusted odds ratio of mRs for CE vs FCA: 0.27, 95% CI: [0.06-0.97], p = 0.039), with no difference in favorable outcome rates. FCA was associated with significantly lower rates of excellent revascularization (21% vs 65%, p < 0.001). No difference in complications' rates was observed between the groups (7.2% in FCA vs 5.5%, p = 0.69). We found that pediatric AIS because of CE etiology has more favorable procedural outcomes compared to FCA following MT. This translated to mixed functional outcomes that may be more favorable in the CE group. These findings highlight the need for further research to refine treatment protocols for pediatric stroke, particularly in understanding and managing FCA in children. ANN NEUROL 2024.

BACKGROUND BACKGROUND
The study aimed to compare outcomes of mechanical thrombectomy (MT) in pediatric patients with acute ischemic stroke (AIS) caused by focal cerebral arteriopathy (FCA) versus cardioembolism (CE).
METHODS METHODS
Data from the Save ChildS and KidClot cohorts were merged. Children with AIS because of FCA or CE that underwent MT were included. The study used the Childhood Arterial Ischemic Stroke Standardized Classification and Diagnostic Evaluation (CASCADE) for stroke cause assessment. Descriptive statistics and multivariable regression models were used to analyze final modified thrombolysis in cerebral infarction (mTICI) scores, periprocedural complications, and functional outcomes assessed by the modified Rankin scale (mRS) at 6 to 12 months.
RESULTS RESULTS
The analysis included 60 children with 14 FCA and 46 CE cases. CE etiology was associated with better revascularization (good to excellent thrombolysis in cerebral infarction scores) and shift toward better outcomes (common adjusted odds ratio of mRs for CE vs FCA: 0.27, 95% CI: [0.06-0.97], p = 0.039), with no difference in favorable outcome rates. FCA was associated with significantly lower rates of excellent revascularization (21% vs 65%, p < 0.001). No difference in complications' rates was observed between the groups (7.2% in FCA vs 5.5%, p = 0.69).
INTERPRETATION CONCLUSIONS
We found that pediatric AIS because of CE etiology has more favorable procedural outcomes compared to FCA following MT. This translated to mixed functional outcomes that may be more favorable in the CE group. These findings highlight the need for further research to refine treatment protocols for pediatric stroke, particularly in understanding and managing FCA in children. ANN NEUROL 2024.
