Key result
The chimney technique was used as a bailout procedure for accidental partial coverage of the left common carotid artery during ISF-TEVAR for left subclavian artery revascularization.
The chimney technique can serve as a bailout procedure for accidental left common carotid artery coverage during ISF-TEVAR in patients with a bovine arch.
Chimney bailout may address inadvertent LCCA coverage in ISF-TEVAR; leaves open durability and generalizability in bovine arch.
We describe the use of the chimney technique as a bailout procedure during in-situ fenestration-Thoracic Endovascular Aortic Repair (ISF-TEVAR) for revascularization of the left subclavian artery (LSA), complicated by accidental partial coverage of the left common carotid artery (LCCA) in a patient with a bovine arch configuration.
