Posterior Cerebral Circulation Approach for Left Vertebral Artery Endoleak Embolization

Type II endoleaks (ELIIs) occur in up to 10% of patients who undergo thoracic endovascular aortic repair (TEVAR) (1). Although after TEVAR, ELIIs are usually considered benign, they can be associated with high reintervention rates (1). Treatment of ELIIs can be challenging due to complex postsurgical anatomy and difficulty in visualization. Urgent treatment of ELIIs is indicated in patients with increasing aortic diameter and/or large endoleak cavities (1). This case is of a patient who had expansion of the false lumen (FL) of a chronic type 1 dissection secondary to ELII caused by retrograde flow from a left vertebral artery (VA) arising directly from the aortic arch.
