A 57-year-old female presented with a left petroclival meningioma fed by the meningohypophyseal trunk of the internal carotid artery (ICA). The enlarged tentorial marginal artery and inferior hypophyseal artery were successfully embolized with the TruFill DCS Detachable Coil System through a 0.019-inch inner diameter microcatheter. Superselective catheterization into the dorsal meningeal artery could not be achieved with the same microcatheter, because the catheter tip was too large to pass into the vessel. Subsequently the feeding artery was successfully embolized with a Guglielmi detachable coil (GDC) through a 0.016-inch inner diameter microcatheter. The patient underwent surgery without blood loss on the day after embolization. Our subjective impression was that the TruFill DCS was softer and had less resistance during insertion, whereas the GDC could be delivered through a smaller caliber system for smaller vessels. Appropriate use of the TruFill DCS and GDCs can allow efficient embolization of the feeding branches of the ICA.
