Extensive basal ganglia hematomas treated by local thrombolysis versus conservative management – a comparative retrospective analysis

Abstract

Objectives: Single-target puncture plus catheter insertion into the clot is a routine step in hematoma aspiration and local thrombolysis for spontaneous intracerebral haemorrhage (ICH). However, multiple-target puncture of this procedure may imply faster hematoma reduction for large-area ICH. We retrospectively examined the outcomes after clot aspiration plus local thrombolysis with single-/double-target and conservative therapy for extensive basal ganglic hematomas. Methods: A case note review was conducted on a consecutive series of ICH patients in a single centre with huge basal ganglia hematomas who underwent clots aspiration and thrombolysis or pure medical therapy. We analysed the clinical presentation, radiological features and treatment outcomes of ICH patients in single-target group, double-target group and conservative group. Results: A total of 92 ICH cases were included in this study. At the post-treatment assessment, the average level by hematoma size in single-target and double-group was respectively smaller than that in the conservative group (20.61 ml vs. 15.75 ml vs 60.53 ml, p < 0.01). The 30-day case fatality rate in conservative group was respectively significantly higher than that in single-target and double-target groups (50% vs. 14.70% vs. 20.59%, p < 0.01). At the time of 6-month follow-up, the proportion of good survival in conservative group was respectively remarkably less than that in single- and double-target group (29.17% vs.64.71% vs. 67.65%, p < 0.01). But no difference was detected with respect to 30-day mortality or long-time outcome between the two micro-invasive groups (p = 0.53 and 0.798, respectively). Conclusion: Our data suggested for the massive basal ganglia hematomas, clot aspiration and thrombolysis can improve the short- and long-term prognosis compared with the pure conservative therapy. But, no evidence was found to demonstrate double-target of this procedure to be more effective than single-target to improve the outcome.
