Successful thoracic endovascular aortic repair (TEVAR) for type B aortic dissections (TBAD) relies on securing the stentgraft's distal landing zone to prevent retrograde flow and false lumen pressurization. We describe a 60-year-old male with a TBAD undergoing TEVAR with electrocautery-wire fenestration of the dissection septum, providing a controlled method to enhance the distal landing zone for graft placement. Postoperatively, the patient experienced spinal cord ischemia, resolving with the placement of a lumbar drain and increasing mean arterial pressures. Follow-up imaging demonstrated a well-sealed repair without endoleaks. This case highlights the importance of surgical technique selection and postoperative monitoring for complications.
