Background: Intraluminal thrombi in the abdominal aortic aneurysms (AAA) were demonstrated to increase aneurysm growth. The effect of treatments on thrombus reduction upon AAA enlargement and clinical endpoints is uncertain Therefore, this study aimed to investigate the effect of antiplatelet and anticoagulant therapy on AAA growth and clinical outcomes.

Method: A total of 357 patients with AAAs were enrolled in this study. They were divided into 2 groups based on their medical therapies. Patients on antiplatelet and anticoagulant therapy were assigned to group 1 (n = 234) and group 2 (n = 92), respectively.

Results: The greatest reduction in thrombus diameter change was observed in patients with anticoagulant therapy (group 1, −2.26 mm; group 2, –8.16 mm; P =.001). The greatest aneurysmal enlargement was found in patients with antiplatelet therapy. There was less AAA progression with anticoagulant therapy than with the other therapy (group 1, 2.08 mm; group 2, 1.31 mm P =.027. The more operational need was observed in patients with antiplatelet therapy than in patients with anticoagulant therapy ( group 1 67, group 2 16, P =.036)

Conclusion: In our study, it was revealed that anticoagulant therapy has been associated with decreased thrombus diameter and less aneurysmal enlargement compared with antiplatelet therapy. Furthermore, this beneficial effect on the thrombus size and aneurysmal diameter decreased the operational need in patients with anticoagulant therapy.
