Robot-Assisted Hematoma Evacuation With Intrahematoma Tenecteplase for Post-Reperfusion PH2 Hemorrhagic Transformation

The purpose of this phase I trial is to evaluate the safety and feasibility of robot-assisted stereotactic minimally invasive hematoma aspiration, followed when eligible by intrahematoma tenecteplase administration, in patients who develop symptomatic supratentorial PH2 hemorrhagic transformation after reperfusion therapy for acute ischemic stroke. The main study questions are whether this strategy is associated with an acceptable early rebleeding risk and whether it can achieve clinically meaningful hematoma reduction with accurate catheter placement and relief of hematoma-related mass effect.
