Infantile dural sinus malformation: curative embolization in two stages with the Scepter mini balloon microcatheter.

Endovascular embolization is the mainstay for treatment of infantile dural sinus malformations.1 2 Distal access and flow control are limiting factors in controlled embolization.3-6 The Scepter mini catheter (Microvention, Aliso Viejo, California, USA) is a low-profile, dual-lumen balloon microcatheter designed to provide navigability in small-caliber, tortuous intracranial vessels. In this technical video, we demonstrate the staged embolization of a dural sinus malformation with multiple arteriovenous fistulae using the Scepter mini catheter (video 1). In the newborn patient, embolizations were performed through the parietal branches of the left and right middle meningeal arteries. The catheter easily navigated into the small feeding arteries. No neurological complications occurred due to the procedures. Post-embolization injections demonstrated significant flow reduction into the malformation. Three-month follow-up angiography illustrated resolution of the previously dilated left transverse sinus. Complete obliteration of the dural sinus malformation was achieved in the newborn patient.neurintsurg;neurintsurg-2021-018608v1/V1F1V1Video 1.
