OBJECTIVES: Intracerebral hemorrhages are associated with significant morbidity and mortality. While the ENRICH trial supports the efficacy of surgical evacuation for lobar hemorrhages, the impact of antithrombotic therapies on minimally invasive surgery outcomes remains unexplored. This study evaluates the effects of chronic anticoagulants and antiplatelets on the technical and longterm outcomes of minimally invasive intracerebral hemorrhage evacuation.
MATERIALS AND METHODS: A prospectively collected registry of patients undergoing minimally invasive surgery for intracerebral hemorrhage from a single institution was analyzed (December 2015-September 2022). Data included key demographics, comorbidities, antithrombotic/reversal status, presenting clinical/radiographic characteristics, procedural metrics, and clinical outcomes. Patients were divided into control (neither therapy), antiplatelet-only, and anticoagulant-only groups, with antiplatelet/anticoagulant reversals conducted per current American Heart Association/American Stroke Association guidelines. Variables significant in univariate analyses (p<0.05) were advanced to multivariable regression models.
RESULTS: Among 226 intracerebral hemorrhage patients treated with minimally invasive surgery, 41% (N=93) had antithrombotic medication history; 28% (N=64) received antiplatelets, and 9% (N=21) received anticoagulants. Patients on both therapies (N=6) were excluded. The antiplatelet group presented more frequently with lobar hemorrhages (56% vs. 37%; p=0.022), while patients on anticoagulants showed increased rates of intraventricular hemorrhage co-presentation (62% vs. 46%; p=0.011) compared to controls. Despite univariate analyses showing a higher postoperative hematoma volume (3.9 vs. 2.9 milliliters; p=0.020) and lower evacuation percentage (88% vs. 92%; p=0.019) for the antiplatelet group, and longer procedures for patients on anticoagulants (2.3 vs. 1.7 hours; p=0.042) compared to control, multivariable analyses indicated that antiplatelets and anticoagulants had no significant impact on these technical outcomes. Longitudinally, antithrombotics were not associated with increased rebleeding, less frequent discharge to home, lower 30-day mortality, or worse, 6-month Modified Rankin Scale scores.
CONCLUSIONS: Patients on chronic antiplatelets and anticoagulants exhibited characteristic intracerebral hemorrhage phenotypes without worse technical or long-term outcomes after minimally invasive intracerebral hemorrhage evacuation, suggesting the procedure's safety for these patients.
