Endovascular Management of a Ruptured Aortic Arch Pseudoaneurysm Using the Snorkel Technique and Coil Embolization

We report a reoperation case of a ruptured infectious aortic arch pseudoaneurysm, which was stabilized with thoracic endovascular aortic repair and snorkel bypass of the innominate artery (IA) and the left common carotid artery (LCCA). A 57-year-old Chinese woman with multiple comorbidities and previous open repair for Stanford type A aortic dissection 5 years ago presented with a ruptured 10.7 cm × 7.3 cm aortic arch pseudoaneurysm involving the origins of the LCCA and the left subclavian artery. The patient underwent emergent endovascular aortic repair with placement of a stent graft in both IA and left carotid artery coursing parallel to the aortic arch endograft.
