Background: Mechanical Thrombectomy (MT) has improved outcomes in acute ischemic stroke (AIS) due to Large Vessel Obstruction (LVO). However, there is limited data on the safety and outcomes of MT in AIS patients with thrombocytopenia. This study aims to assess the efficacy and safety of MT in this population., Methods: Following the PRISMA guidelines, a comprehensive systematic review was conducted using PubMed, Embase, Web of Science, and Scopus. Studies meeting inclusion criteria underwent rigorous risk of bias assessment using the ROBINS-I tool. We compared outcomes between patients with and without thrombocytopenia undergoing MT. Using the R software version 4.3.1, meta-analyses were conducted employing random-effect models., Results: This meta-analysis encompassed data from 5 studies. Thrombocytopenic AIS patients who underwent MT (n = 974) exhibited lower rates of functional independence (OR 0.83, 95% CI 0.71-0.98; p = 0.030) compared to patients with normal platelet counts (n = 2036). In addition, the thrombocytopenic group experienced higher mortality as compared to the group with normal platelet counts (OR 1.76, 95% CI 1.26-2.45; p < 0.001). Rates of sICH were found to be similar between groups (OR 1.20, 95% CI 0.74-1.93; p = 0.456), as were rates of successful recanalization (OR 0.94, 95% CI 0.47-1.87; p = 0.863). Lastly, no significant differences were observed in procedure times between thrombocytopenic and non-thrombocytopenic groups., Conclusion: As compared to patients without thrombocytopenia, thrombocytopenic AIS patients undergoing MT displayed lower functional independence and higher mortality rates, with no significant differences in sICH or successful recanalization., (© 2024.
