Comparison of Outcomes Following Neuronavigation-Assisted Aspiration and Thrombolysis Using Single and Multiple Catheter Insertion for Moderate-Volume Supratentorial Spontaneous Intracerebral Hemorrhage: A Single-Center Retrospective Study of 102 Patients

BACKGROUND: This retrospective study from a single center aimed to investigate 102 patients with isolated moderate-volume (30–60 mL) supratentorial spontaneous intracerebral hemorrhage (sICH) treated with neuronavigation-assisted aspiration and thrombolysis to compare outcomes using single and multiple catheter insertion. MATERIAL/METHODS: We retrospectively enrolled 102 patients (58 single-catheter insertion recipients and 44 multi-catheter insertion recipients) diagnosed with isolated moderate-volume supratentorial sICH who underwent neuronavigation-assisted aspiration and thrombolysis surgery in a single center between March 2017 and December 2019. The impact of multi-catheter insertion on the radiologic and clinical outcomes and complications were compared with those of single-catheter insertion. RESULTS: The baseline characteristics, clinical status, and outcomes of both groups were not significantly different, except for the number of inserted catheters and surgical time. The single-catheter group had a significantly shorter surgical time than the multi-catheter group (39.52±8.76 min vs 61.39±16.6 min; P<0.001). The surgery-related complication catheter tract hemorrhage (CTH) occurred significantly more frequently in the multi-catheter group than in the single-catheter group (8.6% vs 27.3%; P=0.019). In the regression analysis, international normalized ratio prolongation and multi-catheter insertion were independent risk factors for CTH. CONCLUSIONS: Single-catheter insertion is not inferior to multi-catheter insertion for isolated moderate-volume (30–60 mL) supratentorial sICH in terms of radiologic and clinical outcomes and significantly shortened the surgical time and reduced the incidence of CTH.
