Background and purpose: There are risks of recurrent stroke and systemic embolism during the early period after mechanical thrombectomy (MT) especially in patients with hemorrhagic transformation because of delayed initiation of anticoagulants. We assessed the rate of early recurrent embolism (ERE) after MT and the effect of intracranial hemorrhage on ERE. Methods: Patients who underwent MT for acute ischemic stroke in our institution between January 2014 and July 2019 were retrospectively reviewed. ERE was defined as symptomatic recurrent stroke and systemic embolism within 14 days after MT. A multivariable logistic regression model with prespecified covariates including anticoagulants within 48 hours after MT was constructed to determine the association between ERE and parenchymal hemorrhage (PH) within 36 hours (SITS-MOST definition). Adjustment for differences in baseline characteristics between patients with and without PH was performed using the inverse probability of treatment weighting (IPTW). Results: A total of 300 patients (mean age, 75.4 years; female patients, 49%; median baseline National Institutes of Health Stroke Scale score, 18 [IQR, 12-25]) were included. ERE was observed in 12 of 300 patients (8 strokes and 4 systemic embolisms; 4.0%; 95% confidence interval [CI], 2.3 to 9.3). The median time from MT to ERE was 6.5 days (IQR, 3-8) and no ERE occurred before PH. Patients with PH were not likely to be initiated anticoagulants within 48 hours after MT (41 % vs. 77%, p < 0.01). In multivariable analysis, PH was significantly associated with an increased risk of ERE (unweighted odds ratio, 5.61; 95% CI, 1.25 to 25.27, p = 0.025). After weighting for IPTW, PH remained an independent predictor of ERE (weighted odds ratio 6.20, 95% CI, 1.05 to 36.57, p = 0.044). Conclusions: ERE occurred in about 4% of patients after the MT. Our results reveal a dilemma that intracranial hemorrhage after reperfusion therapy may increase the risk of recurrent embolism.
