Complications in Computed Tomography Angiography Following Thoracic Endovascular Aneurysm Repair and Endovascular Aortic Aneurysm Repair

Background: This study aimed to investigate the frequency and types of complications observed in computed tomography angiography (CTA) following thoracic endovascular aortic repair (TEVAR) and endovascular aneurysm repair (EVAR). Methods: This cross-sectional study included 96 patients who underwent TEVAR and EVAR for thoracic and abdominal aortic aneurysm treatment at the Rajaie Cardiovascular Medical and Research Center. Two experienced radiologists evaluated CTA results and recorded the types of complications following TEVAR and EVAR. Results: The mean patient age was 17.82 +/- 56.56 years, with 86.46% male patients. Post-intervention complications occurred in 47.8% of cases, with the most common complications being endoleak (33.3%), occlusion (11.5%), pelvic ischemia (9.4%), hemothorax (3.1%), and hemopericardium (1%), respectively. Although complications were more frequent among women and elderly patients, no significant correlation was found between age, sex, and complication frequency. Conclusions: Over one-third of our patients experienced complications following TEVAR and EVAR. Endoleak, occlusion, and ischemia were the most common complications. To ensure early detection of potential complications, performing at least 1 CTA within a month after the interventions is recommended.
