Abstract
Background: The objective is to study the relation between the velocity of the arterial feeder and the progression of the postendovascular aneurysm repair aneurysm to find out the cut point velocity, which causes a significant increase in size of the aneurysm sac. Methods: Retrospective study of patients with Type II endoleak followed up with the duplex ultrasound between January 2010 and June 2022. The sensitivity, specificity, and accuracy of the velocity, number of feeding artery, and flow pattern were studied. Receiver operating characteristic analysis was performed to evaluate a test performance and the most appropriate cutoff velocity of the arterial feeder. Results: The peak systolic velocity (PSV) of >75 cm/s, multiple feeding arteries, and the to-and-fro pattern show a significant distinguish the stable size from the significant increase in the size of the aneurysm with a sensitivity of 100.0%, a specificity of 100.0%, and an accuracy of 100.0% (P = 0.002). Conclusion: The patient with a PSV >75 cm/s, multiple feeding arteries, and the to-and-fro pattern are correlated with significant aneurysm expansion and need closer follow-up than the patient with low PSV, single feeding artery, and monophasic pattern.
