Abstract

After endovascular treatment of AAA, regular clinical and radiologic surveillance is necessary for early diagnosis and treatment of mid-term and long-term complications. The purpose of this report was to evaluate the efficacy of magnetic resonance imaging (MRI) in screening for type II endoleaks and assessing the results of treatment by embolization. From March 1996 to November 1999, 64 patients with uncomplicated infrarenal abdominal aortic aneurysm (AAA) were treated by endovascular exclusion with a covered aortic stent. Radiological surveillance included plain abdominal roentgenogram (PAR), CT scan, and pelvioabdominal MRI at 1 month, 3 months, 6 months, and every 6 months thereafter. Arteriography was performed routinely after 1 year or sooner if an endoleak was suspected. Based on the results of this study, MRI seems to be more sensitive than CT scanning for detection of type II endoleaks. The negative predictive value of MRI is also better. In this series, all endoleaks were treated by embolization. In most cases, the maximum transverse diameter and maximum anteroposterior diameter decreased after embolization. Further follow-up will be necessary to confirm these findings.
