Surgeon-modified fenestrated stent graft deployment in type B aortic dissection.

The treatment of aortic dissections and aneurysms may be challenging for vascular surgeons. Currently, thoracic endovascular aortic repair is usually the first treatment option for descending aortic pathologies. Left subclavian artery coverage during this procedure is often required to achieve a sufficient proximal landing zone. Most surgeons agree that the left subclavian artery can be selectively covered, but revascularization is preferred to reduce the risk of neurological or ischemic complications. The chimney method, hybrid operations with extra-anatomic bypass, back table or in situ fenestrations are assistive techniques in this procedure. Herein, we present a surgeon-modified fenestrated stent graft for a type B aortic dissection patient.
