Endoscopic ultrasonic aspiration of an intraparenchymal hematoma in a newborn

Neonatal intracerebral hemorrhage is associated with substantial morbidity and mortality. Treatment is largely conservative, though interventions to evacuate intraventricular and intraparenchymal hematomas (IPHs) have been applied. Endoscopic ultrasonic aspiration for the treatment of IPH has increasingly been shown to be a useful strategy in adults; however, it has not been studied in children, and the technology has been more commonly applied to intraventricular hemorrhage (IVH). Here, the authors describe, to the best of their knowledge, the first use of endoscopic ultrasonic aspiration for IPH in a newborn. An 8-week-old female presented with IPH secondary to left M₃ aneurysm rupture, which was treated with coil embolization for aneurysm securement and vessel sacrifice, followed by IPH evacuation using endoscopic ultrasonic aspiration. Through applying this approach in a newborn, the authors gained technical insight not previously reported in the application of this technique in similar cases in adults or in cases of IVH. They highlight this case to share learning points and technical challenges regarding the application of endoscopic ultrasonic aspiration in a newborn along with learning points for imaging and visualization. Endoscopic ultrasonic aspiration can be used to treat IPH in select newborns. Further study is needed to improve efficacy and ease when applying this approach in very young patients.
