Intercostal Artery Pseudoaneurysm Formation after Irinotecan Transarterial Chemoembolization of a Spinal Metastasis from Colorectal Cancer

Figure 3

Left T9 intercostal artery immediately after TACE with irinotecan-eluting beads. Note that there is a small branch off of the T9 intercostal artery which still seems to supply the tumor, indicating the need to repeat the procedure in two weeks to completely chemoembolize the branch with irinotecan-eluting beads.
