Type II Endoleaks Involving an Accessory Renal Artery and the Inferior Mesenteric Artery

Two patients are described with type II endoleaks involving an accessory renal artery and the inferior mesenteric artery. One patient was successfully embolized via the translumbar route. The other continues to be observed; the endoleak is expected to close spontaneously because both the inflow and outflow are significantly compromised.
