Summary
Background Minimally invasive puncture surgery followed by thrombolysis has been proven to be an effective approach for managing hypertensive intracerebral hemorrhage. Nevertheless, its impact on improving neurological outcomes remains controversial. The integration of neuronavigation-assisted stereotactic (NAS) technology will significantly help enhance the accuracy of catheter placement, while tenecteplase (TNK), a third-generation thrombolytic agent, with greater potency in lysing platelet-rich clots and heightened specificity for fibrin may improve thrombolysis efficiency. However, the efficacy and safety of combining NAS minimally invasive puncture combined with TNK in reducing disability and mortality rates among patients with acute spontaneous deep intracerebral hemorrhage remain unknown.
Aim To evaluate the efficacy and safety of neuronavigation-assisted stereotactic MIPS combined with TNK thrombolysis NAS-TNKin reducing disability and mortality in patients with deep hypertensive intracerebral hemorrhage.
Design NAS-TNK is a randomized, open-label, outcome-blinded multicenter trial, involving 732 participants with acute basal ganglia or thalamic hemorrhage with a hematoma volume ranging from 20-50 mL. This study will evaluate the efficacy and safety of NAS minimally invasive puncture combined with TNK, administered every 24 hours at a dose of 0.009 mg per milliliter of hematoma volume, compared to participants receiving standard medical care. All patients will be followed up for 180 days.
Study outcomes The primary efficacy outcome is the proportion of subjects in the NAS-TNK group with a modified Rankin Scale (mRS) score between 0 and 3 at 180 days. The primary safety outcome is the all-cause death at 30-day.
The NAS-TNK study will help improve our understanding of the benefits of NAS minimally invasive puncture combined with TNK in patients with acute spontaneous deep intracerebral hemorrhage. This ongoing research will provide Level I evidence to guide clinicians in managing acute intracerebral hemorrhage treatment options.
