Stent thrombosis in aortic aneurysm: evaluation by multidetector CT *

ObjectiveTo evaluate the demographic characteristics and imaging findings of thrombosis in a series of patients submitted to endovascular stent-graft repair of abdominal aortic aneurysm (ESGAAA).MethodsWe evaluated the imaging features, which allowed the diagnosis of endoluminal thrombosis in a series of 30 patients undergoing ESGAAA and followed from 5 to 29 months, using 64-channel multidetector computed tomography (MDCT).ResultsThrombosis was diagnosed in 10 patients (33.3%), and in 3 of those patients, total thrombosis was observed in an iliac branch.ConclusionMDCT allowed the diagnosis of different types of endoluminal thrombosis in patients submitted to ESGAAA. The use of this minimally invasive diagnostic technique should be encouraged in clinical practice.
