Cerebral Infarctions Following Palliative Transarterial Chemoembolization with Embozene of a Vertebral Body Metastatic Tumor.

Preoperative transarterial chemoembolization has been widely used as an adjunct therapy for hypervascular metastatic spinal tumors. Several therapeutic iodized oil-based agents have been used in combination with anticancer drugs for injection into a feeding artery. Novel spherical agents with narrow-range particles and lower tendency to clump are preferred for the embolization of vascular malformations and hypervascular tumors. We describe the first case of cerebral embolization resulting in posterior circulation infarctions following transarterial embolization of a vascular vertebral body metastatic tumor with Embozene microspheres.
