ABSTRACT
Objective:
To investigate the effect of the number of retrieval attempts on the outcomes after successful recanalization of mechanical thrombectomy in patients with acute ischemic stroke.Methods:
Patients with acute large vessel occlusive ischemic stroke underwent mechanical thrombectomy and successful postoperative recanalization in the Stroke Center of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2019 to May 2020 were retrospectively enrolled. According to the number of retrieval attempts during the procedure, the patients were divided into <3-attempt group and ≥3-attempt group. The demographic data, procedure-related indexes, periprocedural complications and outcomes at 90 d after the procedure were compared between the two groups.Results:
A total of 106 patients, aged 69.8±1.3 years, were enrolled, and 55 were males (51.9%). Eight-three patients (78.3%) were in the <3-attempt group, and 23 (21.7%) were in the ≥3-attempt group. Forty-one patients (38.7%) had good outcomes (the modified Rankin Scale score ≤2) at 90 d, and 11 (10.4%) died. There were no significant differences in the incidence of intracranial hemorrhage (30.4% vs. 20.5%; χ2=1.019, P=0.313), the good outcome rate at 90 d (34.8% vs. 39.8%; χ2=0.188, P=0.665) and mortality (8.7% vs. 10.8%; P=0.999) between the ≥3-attempt group and <3-attempt group, but the incidence of symptomatic intracranial hemorrhage was significantly higher than that in the <3-attampt group (13.0% vs. 1.2%; P=0.031). Multivariate logistic regression analysis showed that the number of retrieval attempts was not significantly associated with poor outcome.Conclusion:
The more retrieval attempts may be related to symptomatic intracranial hemorrhage, but it does not affect the clinical outcomes of patients with successful recanalization at 3 months.
