Abstract:
Thoracic endovascular aortic repair with the provisional extension to induce complete attachment (PETTICOAT) technique can cause persistent false-lumen perfusion through distal re-entry tears, leading to late aneurysmal degeneration and challenging reinterventions. We report the use of renal artery covered stent placement to treat persistent false-lumen perfusion after PETTICOAT caused by a re-entry tear in a 57-year-old man with chronic type B aortic dissection. Preoperative assessment of the relationship between the re-entry tear and bare-stent struts enabled device delivery and false-lumen exclusion, while preserving renal perfusion. This approach represents a feasible branch-preserving reintervention strategy after PETTICOAT.
