Abstract

The objective of this report is to present a challenging case of a mycotic aneurysm of the innominate artery (IA) in a patient with a bovine aortic arch. An 85-year-old woman presented with intermittent fever and positive blood cultures for Staphylococcus aureus. An echocardiogram and a positron emission tomography-computed tomography were performed, showing a hypermetabolic dilation of the IA compatible with a mycotic aneurysm with a type one bovine aortic arch. Conventional open arch repair and total endovascular repair with a custom-made aortic endograft were rejected given the elderly age and need for urgent repair. Treatment was achieved with a hybrid procedure, including a left carotid transposition and exclusion of the aneurysm with a modified Endurant II® iliac limb (two stents were cut off and it was resheathed in an inverted fashion) released through a prosthetic graft sutured onto the right axillary artery, followed by coil embolization of the sac. One year after the repair, the patient is well with complete exclusion of the aneurysm. Under the need for urgent repair, "on-the-table" modification of standard endograft components can be an effective solution for aneurysm exclusion when off-the-shelf endovascular stent ...Continue Reading
