Risk Factors for Spinal Cord Injury After Minimally Invasive Aortic Repair

This study aims to identify factors linked to spinal cord injury after aortic repair. The aorta is the body's main artery. The repairs studied use a fabric-covered tube, called a stent graft, placed inside the aorta. Sometimes, blood flow to the spinal cord is reduced after these procedures. This is called spinal cord ischemia and can cause leg weakness or loss of feeling. Researchers will review existing medical records and scans from adults aged 18 or older. They will compare patients who developed spinal cord ischemia with those who did not. They will examine patients' health, repair details, blood pressure during the procedure, medicines used, and blood vessels supplying the spinal cord. The study will also describe when this complication develops, how it is treated, and how patients recover. It will assess survival and time spent in hospital. The findings may help identify patients at greater risk and inform future prevention strategies. This study uses information collected during routine care. Patients will not need additional tests, scans, treatments, or visits.

Inclusion Criteria: * Age 18 years or older at the time of the endovascular aortic intervention. * Treatment with thoracic endovascular aortic repair (TEVAR), branched thoracic endovascular aortic repair (bTEVAR), fenestrated endovascular aortic repair (FEVAR), or branched endovascular aortic repair (BEVAR). Exclusion Criteria: * Previous or concomitant open aortic procedures.
